Why can't I send text messages on my iphone5? It's the American version. I dialed that number in my head and said I didn't open this service.

The American version is divided into three categories, one is version A, the other is version V, and the other is version S, which is the version of the landlord's mobile phone.

Version a supports mobile and Unicom.

Using v version of tripartite communication,

S version of the mobile phone, wifi, software, that is, except for sending text messages, other functions are normal, that is, you can't send text messages, and there is no solution for the time being. This is a problem with the SMS center. Of course, it will be very useful if the landlord is in America.

It is suggested that the landlord return the goods and replace it with another version of 5, otherwise you can't send text messages and try it out. Call the Unicom artificial station and ask him to send you the number of the SMS information center. You can set this number in the SMS information center of the machine and send it after restarting the machine.
