Actually misunderstanding?"Garakae" does not end with 3G stop (itmedia mobile) --Yahoo! News

au mobile phones (Win devices) will not be available since April 2022

　3G stops of NTT DOCOMO, au, and Softbank are approaching. The timing of the waves is scheduled for DOCOMO on March 31, 2026, au for au on March 31, 2022, and Softbank in late January 2024. [Image] When the 3G mobile service that can be used after 3G stop is completed, it is often reported that conventional mobile phones (feature phones) and so -called "Garakae" cannot be used, but there are misunderstandings here. increase. Not all conventional mobile phones cannot be used. Let's look at the au case, which is the closest to 3G stop. au will end the 3G communication service "CDMA 1X Win" on March 31, 2022. Along with this, voice calls and data communication will not be available on Win terminals and smartphones and mobile phones that are not compatible with au volte (even if LTE is not compatible, data communication will not be available). The Win device contains so -called garage, but in fact some smartphones can no longer be used at the end of March 2022. In the case of iPhone, it corresponds to the iPhone 4s that is not compatible with LTE and the iPhone 5 / 5s / 5c that does not support au VoLTE. Then, what about mobile phones? Like the iPhone mentioned earlier, models that do not support au voltes can no longer be used at the end of March 2022. In other words, if you are compatible with au VoLTE, you can continue to use it after April 2022. The mobile phone compatible with au VoLTE has the "G'zone Type-XX" just released on December 10 in the latest model. The oldest is the "AQUOS K SHF32" released in July 2015, and "Infobar XV", "Gratina KYF39 / Kyf42", "Easy Mobile KYF41", and "Easy Mobile Light KYF43" are also compatible with au VoLTE. increase. Both have a familiar numeric keypad with conventional mobile phones, and are folded except for Infobar XV. For users who are eligible for the service termination, KDDI is taking measures to replace it for free for smartphones and au VoLTE compatible mobile phones. Free replacement models include simple mobile phones and Gratina (KYF42), so those who are familiar with the familiar folding will be a candidate. Then, what about docomo and SoftBank? If you have a mobile phone that supports LTE and VOLTE, you can use data communication and voice calls even after 3G stop. It is important to note that voice calls will not be available if they do not support VoLTE even if they are compatible with LTE. In relatively new models, DOCOMO is LTE, such as "ARROWS mobile phone F-03L", "AQUOS mobile phone SH-02L", "Card mobile phone KY-01L", and SoftBank is "Digno Mobile Tay 3", "AQUOS Mobile 3", and "Easy Mobile Phone 10". And support VoLTE. A few readers of ITMEDIA Mobile are using conventional mobile phones as the main, but if you have a mobile user around your family or around you, you may want to check if it supports LTE and Volte. In addition, all three carriers have strengthened the transfer measures to smartphones, and it is likely that new mobile phones will decrease in the future. au has introduced new mobile phones in 2021, including G'zone Type-XX and Gratina, but DOCOMO has not included new mobile phones since 2020 and Softbank after 2021. 。 If you still want to use a mobile phone for several years, you should get it early.
