Translation and explanation of revised Japanese SIM lock guidelines

Edit: I forgot to mention the best part. Not only will it be free, it will also be automated, meaning no more painful, time consuming experiences dealing with untrained shop staff. And, that of course means you will be provided with the unlock code.

I've now read the updated SIM unlocking guidelines from the Ministry of Infrastructure and Communications (MIC). I've also translated them below.

In short, I'm very pleased with the new guidelines. They are short, concise, specific, and (most importantly) thorough. I was worried that the MIC would focus narrowly just on SIM locks, leaving carriers free to cripple phones by a myriad of other means, such as locking out the APN settings menu on the phone (like Apple typically does).

The guidelines specifically state that any other restrictions added by carriers should be removed. Hopefully this means the end of the Docomo's automatically changing of APN when tethering, which breaks tethering with MVNOs, other SIM cards, and the mopera.net ISP.

The guidelines also specifically state that carriers can no longer unlock a phone then refuse to provide service using non sequiturs like "because your phone is unlocked we are no longer able to service it." That is as logical as saying the train was a minute late because I put ham in the refrigerator.

Carriers will also be required to specifically disclose which frequency bands a phone supports,  as well as what services will cease to work. Currently, getting this information from docomo is tedious and uncertain.

Phones will still be sold in a locked state, and the guidelines allows for an a short period of time that the phone cannot be unlocked.

It would seem that Juggly was right (as usual). There is no room at all that I can see for carriers to take an opposite approach and cripple unlocked phones.

The guidelines do not go in effect until May 2015. Though there is a clause stating that these guidelines should apply to phones announced before that date, I do not at all expect that to happen. In that sentence, there was a line break that caused me to read over a very important character, 前. The old guidelines will apply to existing phones. Purchase phones that initially go on sale after May 5.

(なお、それ以前に発売された端末については、平成 26 年●月改正 前のガイドラインの趣旨に沿って適切に対応することが適当である。)

For the iPhone, this would mean the next iteration that would presumably become available around October/November 2015.



(Anything in [brackets] is added by me.)

May 2010 (Revised: 2014)

Overview


Currently in Japan, handsets provided by MNOs are "SIM Locked," preventing usage on other mobile networks.

Users of these devices have expressed the desire to both use their domestic devices while overseas with locally-obtained SIM cards and to continue using the same phone after porting their number to a different MNO.

Due to problems arising from large differences in specifications [i.e., WCDMA v CDMA-2000], frequencies, and platforms [i.e., carrier mail, etc.], individual MNOs were requested to voluntary abide by the "Guidelines Concerning SIM Locks" in 2010.

However, unlocking by MNOs remains limited at present. In addition, SIM locks have not only hindered users, but have also increased the cost to other MNOs of acquiring new customers, partially leading to the [unreasonably] large cash back offers.

Now, the spread of LTE and smartphones has changed the mobile marketplace, increasing interoperability of specifications and frequencies between MNOs. Therefore, both the basic and specific points of these guidelines should be adjusted accordingly.

Note: The guidelines defined 役務 (service) as electronic communication services concerning mobile phones, including mobile phone access service, 3.9G [LTE] access service, and virtual mobile electronic communication services associated with mobile phones.

Ministry Opinion


Article 29, Paragraph 1, Item 12 of the Telecommunications Business Act of 1984 allows for the invoking of measures to reform telecommunication practices that are unreasonable or unjust and may or do result in unsound industry development or are not in the best interest of the populace.

SIM locks constitute an inconvenience that prevents receiving service with existing handsets upon switching MNOs, as well as usage of a locally-obtained SIM card while overseas. SIM Locks further increase the cost incurred by MNOs in recruiting new customers and are the cause of differentiation in service fees and content [between new and existing customers], hindering competition. SIM locks are also the root of the large cash back offers used to acquire new customers that are promoting an unfair situation between longterm users and those who frequently change MNO.

However, MNOs have expressed the following concerns regarding not implementing SIM locking. 1) Lack of full support by other MNOs for unlocked handsets may cause confusion for users. 2) Compared to a market with locked handsets, promotional costs will increase, likely resulting in retail prices above current. 3) Loss of incentive to develop original brands and services.

Regarding 1), it is appropriate to leave the decision to users after sufficient explanation. Regarding 2), it is not likely to cause a large problem considering the typical user situation in which an amount equivalent to the handset cost is discounted monthly from the service cost. Furthermore, the cash back amounts at the time of purchase have become excessive, creating an unfair situation between longterm customers and frequent switchers and becoming a problem for fair competition. The removal of SIM locks is expected to result in restraint regarding these promotions. Regarding strategies for original branding (3), rather than using SIM locks to forcibly retain customers, it is preferable to develop and provide services that take maximum advantage of a handset's appeal.

Thus, the above concerns do not constitute proper and reasonable grounds to continue SIM locking. Finally, the traditional problem for unlocking (incompatible frequencies, standards, and specifications) continues to be lesser and lesser of a problem.

Considering the above, MNO's users (including those who have already cancelled service) have called for unlocking handsets, and in the lack of valid justification to the contrary from MNOs, it is necessary to invoke measures to reform current practices under Article 29, Paragraph 1, Item 12 of the Telecommunications Business Act to protect the interest of users and foster sound industry development.

Specifics for SIM unlocking

  1. Eligible handsets
    1. Carriers should in principle remove SIM locks from all handsets.
    2. Refusal to remove SIM locks is limited to cases that would result in unfair competition or excessive hinderance to usage with other carriers. (This applies to specialized devices that pose technical issues, i.e., nonstandard mobile specifications or frequencies and does not include general usage devices such as those commonly known as feature phones, smartphones, tablets, mobile routers, and USB modems)
  2. Unlocking process
    1. Carriers should whenever possible quickly and simply conduct unlocking through the internet or over the phone at no additional cost. (Alternate means for unlocking at no cost does not preclude the levying of a service charge if in-store unlocking is performed at the customer's request. A service charge may also be levied against customers with no active service contract for in-store unlocking.)
    2. Carriers may make exceptions and add a limited no-unlock period to prevent improper use of unlocked phone and mitigate the risk of loss of subsidized phones
  3. Unlocking process should be set in advance and publicly disclosed

Points to note during SIM unlocking

  1. Explanation to Users
    At the time of handset sale, SIM unlocking, or conclusion of a service contract, MNOs should make reasonable effort through means such as in-store explanation, pamphlets, or websites to ensure that the user understand the following points in particular.
    1. At time of purchase
      1. Whether the handset is eligible for unlocking
      2. The conditions and process of unlocking
      3. Which mobile services, applications, etc. will be partially or fully inoperable with another MNO SIM card
      4. The frequency bands supported by the handset
    2. At time of unlocking
      1. The conditions and process of unlocking
      2. Which mobile services, applications, etc. will be partially or fully inoperable with another MNO SIM card
      3. How to obtain service or repair for the unlocked handset
    3. At time of contract conclusion
      Which mobile services, applications, etc. will be partially or fully inoperable with another MNO SIM card
  2. Clarification of means for inquiry by users of unlocked handsets
    MNOs should consult with handset makers to prepare and clarify a means to perform service on unlocked handsets.
  3. Confirmation of proper technical certification
    MNOs should make efforts to confirm that uncertified phones are not used on their network.

Others

Because it is desirable that unlocked handsets are as fully functional as possible, appropriate effort should be made to remove together with the SIM lock any additional restrictions on functionality that were set by the MNO.

Implementation of these guidelines

  1. These guidelines will be applied to new devices brought to market after May 5, 2015. It is further appropriate to suitably apply the pre-2014 guidelines to previously announced handsets.
  2. The Ministry of Internal Affairs and Communications will reevaluate these guidelines as necessary following based on the situation following implementation.

Reasonably priced voice and data rental SIMs finally come to Japan: B-Mobile PAYG


SIM card rental in Japan is exorbitantly expensive because law prohibits non-residents from obtaining cellular voice contracts, blocking them out of the (relatively) reasonably priced market. The only options are rental services.

The rental market predates 3G, and Japan never used GSM. In the past, visitors had no choice but to rent hardware, which created an environment that (somewhat) justified premium pricing. There was no significant decrease in price following the start of SIM card rental after introduction of 3G networks, and once smartphones proliferated, mobile data options were added data but at laughable prices.

Not anymore.

Inexpensive data with a voice rental SIM

The B-Mobile line of SIM cards from Japan Communications, Inc. (JCI) got a new product today, the prepaid PAYG rental SIM, which provides 60 minutes of outgoing voice calls (incoming is free) and 3GB of 3G/LTE data for ¥9,980. The SIM is active for 7 days, after which any remaining data and minutes become invalid. The specifics are:

B-Mobile PAYG Rental Voice and Data SIM
  • ¥9,980 for 7 days
  • 60 outgoing domestic/international minutes
  • 3 GB 3G/LTE data
  • 5/75 seconds deducted for domestic/international SMS
  • Free tethering
  • incoming calls and SMS free
  • Prepaid (no worry of unexpected, additional charges)
  • Nano, micro, standard SIM card sizes
The SIM card can be purchased in stores (Yodobashi Camera) or preordered. Unfortunately, complying with Japanese law complicates the activation process. If you preorder, you will first set an activation date and upload a scan or image of the passport page with your photo. Then, following activation but within 24 hours of arrival in Japan, you will have to also upload pictures of 1) your entry stamps and 2) the image of the same passport page originally uploaded. If you buy in a store, then you will need to upload all this together as soon as possible and wait for activation.

In a press release, JCI indicated they are working with the government to try and smooth the activation process. By the way, if Tokyo police have their way, this will be required for ALL SIMs sold to non-residents, even data-only SIMs, which means that most MVNOs won't bother to go through the effort and just start requiring residency for data-only SIMs, just like for voice SIMs.

Traditional data costs with a rental voice SIM

At ¥110/day and ¥110 per minute (with a ¥315 service fee), the current SoftBank rental SIM would cost ¥7,685 over a 7 day period if a comparable 60 minutes were used – a better value for just voice. However, if you want to have minimal background data usage for mail, maps, etc., the SoftBank rental costs increase quickly.

Softbank rental data fees are ¥0.32/packet (128 bytes). Doing the math yields the following:
  • 1 KB: ¥3
  • 1 MB: ¥2,621
  • 2 MB: ¥5,243
  • 250 MB: ¥655,360 ($6,500US)
  • 1 GB: ¥2,684,355 ($27,000US)
  • 3 GB: ¥8,053,064 ($80,500US)
Yes, current Japanese rental SIMs value 3 GB of mobile data at 80,000 US dollars. As I said, laughable. Of course no one would ever use this much, and the daily maximums are capped I believe, so it wouldn't be possible anyway. However, because the traditional rentals are postpaid with a credit card, there will always be the concern of incurring additional charges.

A more realistic comparison

Long time readers will recall that I once did an experiment over about 8 months with a b-mobile FAIR data-only SIM. (There is an interactive chart showing how I consumed data during those 240 days at the bottom of this post.) The FAIR is wide open with no proxy or speed restrictions (and accordingly priced). 1 GB of data costs about ¥8,000 and is good for four months. This translates to 250 MB for ¥2,000.

All the other MVNO SIMs, especially the other b-mobile products, are speed restricted and relatively high latency. Because of this, I think it would be near impossible to use 3 GB with the PAYG SIM in 7 days (or even in an entire month). So comparing prices based on high data consumption is completely unrealistic.

Rather, I will compare prices based on my experience with the FAIR SIM because I think my behavior regarding data usage with a 250 MB monthly quota is a good analog for the way people use traditional Japanese rental SIMs. That is, I thought about the cost of everything I did with the phone. On light-usage days, I would consume around 2 MB, which is the equivalent of uploading one or two photos.

Let's compare costs by taking about a quarter of my light-day usage, 500 KB. Seven days with a Softbank rental SIM, using 500 KB per day and 60 minutes total, would cost ¥16,645. To bring the cost down to the PAYG SIM price over 7 days, total data usage over the entire week must be limited to just under 1 MB. One. Megabyte.

Good luck with that.

Supposedly leaked Nexus 5 service manual indicates support for Japanese LTE bands.


If this is really the Nexus 5 service manual, then this is good for Android users in Japan: Support for LTE without having to deal with a device that locks you out of mobile network settings.

FDD-LTE: Bands 1, 3, 5, 7, 8, 20.
WCDMA (HSDPA 3G): Bands 1, 2, 4, 5, 8

Band 1 is Docomo and Softbank's 2100 MHz, used for both LTE and 3G. As far as I can tell, the Nexus 5 does not support the low frequencies of either carrier, though.

CDMA is mentioned in the manual, but as you can see below, it is not listed as a "Supporting Standard". Therefore, my guess is that the reference to CDMA is probably just a standard copy-paste, to be read as "IF this did CDMA, here's what it would be."

However, as far as I can tell, CDMA is unsupported. (Also FeliCa, mobile Suica, etc. is not supported.)

Tokyo Police push ID verification for data-only SIMs

This sucks and is about as well thought out as a knee-jerk reaction from a politician who knows the internet is in fact not a truck but instead thinks it is a series of tubes.

It will mean the end of cheap data SIMs for visitors, and it's going to take away a large source of revenue during the Tokyo Olympics for scrappy MVNOs like JCI. Maybe the Police haven't considered the olympics and the number of visitors that would need mobile data access, or the have and that scares them.

As I have mentioned numerous times (and why I think an unlocked iPhone could have been a game changer), MVNOs usage is exploding in Japan. The idea that "Japanese people don't even know what a SIM card is" outdated and no longer really applicable. True, there are some that of course do not, but if the Metropolitan Police is making an issue of MVNO SIMs, that means a LOT of people are using them.

Anyway, here is the issue. From the Yomiuri:
通話は従来型の携帯電話、メールやネットはスマホ――携帯電話を使い分ける利用者の増加に伴い、データ通信専用のSIMカードの需要は急増している。

SIMカードは2008年、携帯電話不正利用防止法で販売時の本人確認が義務付けられたが、データ通信用カードは当時、「通話機能がないので、犯罪に悪用されるとは想定していなかった」(総務省)として規制対象から外れた。

しかし、スマホ向けの無料通話アプリの登場で、データ通信用カードでも、このアプリをダウンロードすれば通話ができるようになった。

警視庁幹部は「技術の進歩で、データ通信用カードも通常のSIMカードとほぼ同じ機能を持つことになった。早急に本人確認の義務付けが必要だ」と指摘している。
As the number of people who use a traditional feature phone for voice calls and a smartphone for mail and internet increases, so does demand for data-only SIM cards.

In 2008, a law was enacted requiring identification verification for the sale of voice SIMs, but data-only SIMs are exempt because the Ministry of Infrastructure and Communications didn't imagine they could be used for nefarious purposes since they lacked voice capabilities.

However, downloading free smartphone apps allow voice communications with data-only SIM cards.

Therefore, Tokyo Metropolitan Police Chiefs have pointed out that "as technology has evolved, data-only SIM cards now effectively posses the same functions as voice SIMs. It is necessary to immediately begin identification verification for [data-only SIMs]."
On slashdot.jp is the following:
事件では、データ通信用SIMを使ってLINEやカカオトークといったコミュニケーションアプリを利用し、女子高校生を集め売春させたとのこと。
One incident involved the usage of LINE and KakaoTalk to recruit high school girls into prostitution.
As I understand it, when Line detects a "44010" SIM*, it requires you to login to your mydocomo page, which users of MVNOs don't have. This means line can't even be used with an MVNO (of course other services can, though).


*440 is Japan's Mobile Country Code and 10 is Docomo's Mobile Network Code. So a docomo SIM is often simply referred to by phone geeks as a 44010 SIM. MVNOs using Docomo's network provide 44010 SIMs (which is why they will be locked out of the Docomo iPhone 5S and 5C).

INGRESS tourism in Tokyo

UPDATED with mobile 3G data options for visitors.

Photo by J. Maurice.
December would appear to have been an unusually slow month at Japan Mobile Tech if you were only counting the number of blog posts (three including this one). The reason for the low post activity is preoccupation with something else:

Ingress


Every contributor to JMT is participating in the closed beta of Google's surprisingly addictive GPS maps-based, augmented reality game. (Sorry, we don't have any invites.) One contributor actually left another contributor waiting for over an hour at a local craft beer establishment (!) because he was fighting to retake several portals from The Enlightenment (green). (May we suggest The Resistance as the path best chosen by newcomers?)

If you are unfamiliar with the game play and back story, it doesn't really matter. It's very simple: control predetermined points and take territory by linking three into triangles uninterrupted by enemy links. In Tokyo, most of the Googlers are playing on the side of The Enlightenment, which gave them a headstart and a stronghold in the Roppongi, Shibuya, i.e., the Yamanote area. The Resistance are relegated to shitamachi, which is actually quite appropriate because it gave The Enlightenment time to obtain higher levels and more territory — resistance should be defined by lower numbers occupying less desirable areas.

Two remaining resonators were best destroyed from inside a station

A side benefit (really the entire purpose of the game) is improved navigational data (and likely more) for Google Maps. If you can't agree to sharing anonymized location data with Google, then this game isn't for you. I actually see this as not just a good thing, but a brilliant thing. Google's walking directions in Japan, which are still in beta form, need a lot of work. They've gotten better since introduction but will still often direct you across multiple lanes of traffic in locations where no proper crossings exist.

Just ask Apple. You can't build a mapping service from scratch with crowdsourced data.

But you can powerfully augment a robust database with the fundamental background layers already in place. Rather than providing a path to walk, provide two points and analyze the route.

Lose the guidebook for a day



If you've got a day in Tokyo, why not leave the guidebook at the hotel and explore lesser known areas on foot? Many of the "portals" are shrines, monuments, or temples, and often the most interesting of those are not necessarily the largest and most famous.

For getting around, each of the Subway companies (unfortunately there are two independent ones) offer 1-day passes, often for less than the cost of opening a taxi door. Each network is well built out and can get you within a few kilometers of any portal in the 23 wards of Tokyo. Add a few hundred yen for the occasional JR or private rail ticket and you can get just about anywhere.

The best value are the Toei tickets for the services operated by the metropolitan government. All Toei subways (Asakusa, Oedo, Mita, Shinjuku) can be ridden all day for ¥500. However, this is only available during weekends and public holidays during certain times of the year. The standard pass is ¥700 and available all year. This adds the extensive bus system, the rustic Arakawa Line tram, and the Toneri Liner, which departs from Nippori (which is in need of a stronger Resistance presence).

Mobile data options


Japan Communications Inc (JCI) sells a variety of prepaid data-only SIM cards, primarily under the "b-mobile" branding. For around ¥3,000 (perhaps a bit more), you can have mobile data access for portal hacking. Make sure your phone is 1) unlocked and 2) supports UMTS Band 1 (2100 MHz), as explained here. These SIMs can cause high battery usage in some phones, but there is a patch for most rooted phones.

See our comparison of b-mobile SIMs. The easiest by far (but at a relative premium price) are the Visitor SIMs, which can be delivered to a hotel or picked up at major airports.

The "U300" and other reduced speed products might not be the best choice as they have high latency, and Ingress needs to have actions synched between the servers and all clients simultaneously. The 1GB options, which have much fewer speed restrictions, will be more suitable.

The absolute best value is the "1GB Flat Rate" SIM purchased from a major electronics retailer, but this requires activation from a Japanese mobile phone and has no English support other than "pressing 2 for English" during the activation process.

B-Mobile visitor SIM airport pickup


JCI's new Airport pickup Service allows Visitor SIMs to received directly from an airport post office. For an additional ¥210 a SIM card can be sent to New Chitose, Narita, Haneda, Chubu, Kansai, Hiroshima, Fukuoka, Kagoshima, and Naha International Airports. This appears to use Japan Post's Yubinkyoku-dome(郵便局留め)service. A passport is all that is needed for pickup.

A word of warning: Confirm that your flight is scheduled to land during the post office's operating hours! If you flight is delayed or your other wise don't have tim to pick up the SIM before it closes, the package cannot be redirected to your hotel. You'll have to go back and pick it up the following day, which can be quite expensive and time consuming, depending on how far away the airport is located.

This is something that JCI should have done from the beginning. There was originally no differentiation between the standard U300 and Visitor SIMs, other than of course the English support. After prices were increased for the Visitor SIMs, no additional value was added. Airport pickup service now gives people more of a reason to purchase a Visitor SIM.

The extra fee for airport pick up is a bit dubious, though, because the post office doesn't charge any extra for Yubinkyoku-dome.
