Hi I'm travelling to the USA for a holiday later this month and I'm currently on a sim only deal that does not allow roaming to the USA. I am looking to buy a USA sim but not sure if my phone would be compatible. Does anyone know if my iPhone 7 plus would be compatible and which sim would be best?
Windows, Windows 10
If your iPhone is carrier-locked, you’ll need carrier roaming, or will need the carrier to unlock it.
If your iPhone is not carrier-locked, most any nano SIM will work.
AT&T, Verizon, and T-Mobile are the major US carriers with networks. Most of the rest of the advertised carriers are mobile virtual operators reselling access into one of those three networks.
As for carrier choices, there are websites with pricing comparisons.
If your phone is not carrier locked then your phone will be compatible. If it is carrier locked contact your carrier and ask about unlocking. I can’t offer advice on what PAYG SIM to get, but any reputable carrier is fine (AT&T, Verizon, T-Mobile, Cricket, MetroPCS, etc)
iPhone 7 plus USA sim compatibility?
