The U.S. version depends on what operator,The four major operators in the United States,Only the United States V and the United States S support three networks (that is, additional support for telecommunications)

Then you look at whether your machine IMEI starts with 99, if so, it is a triple network machine.

And if your machine is unlocked, it is the kind that does not need to be carded, so you can telecompose without a card at the beginning of 99.

The U.S. version can be unlocked, and if there is no lock, it will not support [you need to cooperate with the card to use the mobile 4G card].

query locked and unlocked methods; Insert the mobile phone card of China Mobile or China Unicom into the mobile phone, and then go to the "Settings - General - About this code vibrator - Operator" in the mobile phone.

3. The above is the situation that the card patch is not installed on the locked machine, if the card patch is installed next to the mold after jailbreak or the card is installed, it will display China Mobile China Unicom, etc., the problem is that there is no such high operator version so far, and the operator will not change after changing the card, for example, the mobile card is China Mobile, and the Unicom card is changed or China Mobile, so the defeat is whether the card is inserted or not, as long as the operator displays China Mobile China Mobile above, China Unicom, it is a locked machine.
