Can I reuse au SIM cards on iPhone and Android?: Cheap SIM Q & A (extra edition)
question
I'm using au's iPhone 5 now.Recently, I'm a little sick, so I'm thinking of replacing it with a SIM rock -free Android smartphone sold at electronics retailers.
In this case, is it possible to use the SIM card in the iPhone 5 as it is?The iPhone 5 will be used as a spare machine after initializing, so I hope both can be used ...

It is not impossible, but there are quite a lot of things to note.(ITMEDIA MOBILE editorial department Inoue)
In the previous Q & A, a question was asked, "Is it possible to use NTT DOCOMO SIM cards with Android smartphones and iPhone?"
As I wrote at the end of the answer article, similar questions have been received from those who use au (KDDI and Okinawa Cellular Phone) and Softbank.This time, I would like to answer about au.
To put it simply, if you have a 4G LTE contract nano SIM card (au nano IC card) that contracts "LTE Net for Data", it is not impossible to reuse it.However, there are many points that you have to be careful about when you compare with DoCoMo, so I will explain in detail.
なお、SIMロックフリー端末でのau回線の利用については、以前のQ&A「SIMフリースマホにキャリアの既存SIMを挿して使える？」でも取り上げていますので、合わせて参考にしてみてください。

注意1：LTEの「Band 1」に対応していても適法に使えるとは限らない
The au mobile phone network is compatible with the following frequency band (Band) (mainly frequency band).
Theoretically, it is compatible with the above frequency band, and it can be used with au if it is a terminal that has acquired "Certificate of Technical Standards of Specific Radio Equipment (such as technical correspondence)".If it supports at least LTE's band 1, it should be used in the same area as the iPhone 5 or the iPad (2012 model) (reference link).
The important thing here is the word "should".The LTE BAND 1 used in the au network is close to the frequency band used by Y! Mobile PHS.Therefore, terminals that use LTE BAND 1 in the au network require a separate measures to avoid interference with the PHS band.If an au SIM card is inserted into a terminal that has not taken this measure, it will not be legal even for a terminal that takes skills.
Therefore, if you use a SIM lock -free Android smartphone with au, be sure to use a clear support to the au network, or if you specify not compatible with au network, be sure to never use it.please.If you are not sure if you can use the model you want to use on the au network, make sure.
KDDIが公表している「当社ネットワークへの接続性検証に関する申込みから検証までの流れについて」（PDFファイル）では、auネットワークに接続する端末にPHSとの干渉対策を施すように求めている注意点2：au 4G LTE契約には「LTE」と「VoLTE」の2種類がある
There are two types of voice call contracts for "au 4G LTE", "LTE Dual (LTE)" and "VoLTE".The simple way of distinguishing is the following features.
Both contracts can use data communication in the same 4G LTE area.However, considering the premise of making a voice call, the LTE contract requires a CDMA2000 -compatible terminal, and the VOLTE contract requires VoLTE -compatible terminals.As mentioned in the previous Q & A, there are not so many SIM lock -free terminals that support au 3G communication or VOLTE, and you will now choose from the following options.
If you don't need voice calls (you only need data communication), you will have a little more options, but the compatible models are limited due to the circumstances listed 1.
The au's iPhone supports VoLTE calls from "iPhone 6", but unlike other terminals, it is now available in Volte by switching operations on the terminal side.If you use the SIM card of the iPhone you bought on au with an Android smartphone, prepare a CDMA2000 compatible.
Conversely, if you use the SIM card used in the Android smartphone of the LTE contract with the iPhone, you need to apply for a free "network setting option".Applications can be made from the web's "au customer support".
On the other hand, if you want to use a VOLTE -compatible Android smartphone! You can change your contract and replace the SIM card at the au shop.The commission is 3000 yen.However, if you use a VOLTE contract SIM card on your iPhone, you will need a SIM lock -free version or a SIM -locked VoLTE compatible iPhone.As long as I verified it, I was able to use a VOLTE contract SIM card with "iPhone SE" (reference article) without SIM locks.
4G LTEは契約区分によってSIMカードが異なる。左がLTE契約用の黒いSIMカード、右がVoLTE契約用の銀色のSIMカードThe same applies to the MVNO (virtual mobile telecommunications carrier) service that uses the au line that the contract is divided between "LTE" and "VOLTE".The caution is basically the same as the genuine line, but you need to keep in mind the following points.
注意3：他社端末を使う場合は「LTE NET for DATA」の契約が必要
There are two types of data communication services for au 4G LTE, "LTE NET" (300 yen per month) and "LTE NET FOR DATA" (500 yen per month), but if you want to do data communication with an AU brand that is not an au brand.A contract for Net for Data is required.LTE NET and LTE NET FOR DATA can be applied, but there are no particular discounts.
AU's Android smartphone and iPhone also support both internet connection services.However, if you use LTE NET FOR DATA on your iPhone, you need to install the APN profile separately.
