Oshimu -chan Recently, I often heard the word "SIM unlock". What is it?
What are you talking about, Shimo -kun?It's not to "unlock SIM lock".
I'm Oshimu -chan, so I don't know what the "SIM lock" is in the first place!
Shimoku -kun.
Uncle Sim Maema.SIM lock is a lock function that hangs on the terminal so that it does not recognize the SIM card of another telecommunications company.For example, a mobile phone (smartphone) sold by NTT DOCOMO can only communicate with docomo SIM cards.
SIM -free smartphones (SIM lock -free smartphones), which can use Shimokun -kun cheap SIM, do not have SIM lock, so if you have a network, you can use it with any communication company's SIM card.
Oshimu -chan.So what does it mean to "unlock it"?
Uncle Sim "Unlock SIM" = "SIM lock -free".Until now, Japanese mobile phones could not be unlocked, but the Ministry of Internal Affairs and Communications' policies have been required to unlock the SIM in principle for mobile phones to be released after May 2015.。By the way, DOCOMO had accepted the SIM lock release before, but SoftBank and KDDI had the same levels of three companies in response to unlocking.
In order to unlock the SIM, about six months have passed since the terminal was purchased ( * 6 months later, au is 180 days later, SoftBank is 181 days later), so unlock it immediately!That's why.
SIMロックを解除すると、1台もスマホでさまざまな通信事業者のSIMカードを使えるようになるOshimu -chan That's right!So, if you cancel, you will be able to use other companies' SIM cards.
Uncle Sim That's right.For example, if you unlock a docomo smartphone, you will be able to communicate using au or SoftBank SIM cards.
Shimo -kun, but for cheap SIMs, you can use a cheap SIM using a docomo network without having to unlock the SIM.
Uncle Sim That's right.When it comes to cheap SIMs, au and Softbank smartphones have a greater advantage of unlocking SIM.In particular, cheap SIM services for individuals using Softbank lines are not offered so far, so the merits are great.
Shimoku -kun au device can be used without unlocking SIM locks with mineo or UQ mobile.
Uncle Sim, however, should be aware that Mineo or UQ Mobile will not be able to use Mineo or UQ Mobile unless the SIM lock is unlocked.
Oshimu -chan Speaking of which, a friend who uses SoftBank's iPhone lamented, "I can't use it on my terminal!"
Uncle Sim, that friend, what generation of iPhone do you use?
Oshimu -chan Uh, it's definitely "iPhone 6".
Uncle Sim, I'm sorry, but the iPhone 6 is a model released before May 2015, so I can't unlock the SIM.At the moment, the iPhone can unlock the SIM is the iPhone 6s, the iPhone 6s Plus, and the iPhone SE.
Oshimu -chan Oh, that's right.
現在、日本のiPhoneでSIMロックを解除できるのは、写真のiPhone 6s／6s Plusか、iPhone SEのみUncle Sim Another thing I want to keep in one corner of my head is the corresponding frequency of the terminal.DoCoMo, KDDI, and SoftBank have published on the website (docomo * PDF, KDDI, SoftBank * PDF) on what frequency their terminals correspond to.
The frequency used by DOCOMO is LTE 700MHz band (Band 28), 800MHz band (Band 19), 1.5GHz band (Band 21), 1.The 7GHz band (Band 3), 2GHz band (Band 1), 3G are 800MHz bands (Band 6 and 19), 2GHz band (Band 1), so it is necessary to support any of these.
各キャリアが公開している、端末の対応周波数。こちらはソフトバンクの端末Oshimu -chan, it seems to be somewhat difficult.
Uncle Sim, with au and SoftBank smartphones, the frequency band of docomo is covered somewhere.In particular, the iPhone has a wide range of frequency bands, so it is safe.In Android, some of the frequency bands of other carriers may not be covered, but I think it is rarely inconvenient for everyday use.If you are interested, please check it.
How do you unlock Oshimu SIM?I wonder if I have to go to the store?
Uncle Sim Uncle can be canceled at each carrier shop, but it costs 3000 yen (excluding tax).The recommendation is to release it on the website.You can release it for free on a website.
Oshimu -chan, but to release it yourself, the hurdle seems to be a little high ...
It's okay if you work according to the instructions on the Uncle Sim site.As a rough flow, enter the terminal's manufacturing number on the support page of each carrier and apply for cancellation.After that, if you operate the terminal, you'll be done.The release method is slightly different between Android and iPhone, but it can be released in about 10 minutes.For more information, check the website of each company (docomo, au, Softbank).

Shimoku -kun is always free, so if you have a good girl, please introduce it.
