Does anyone know if these will work with cricket wireless?
Cricket is now owned by AT&T so yeah, probably. They used to be different, but from what I just googled, you will most likely be A-OK Good-To-Go.
I’m looking for an iPhone 6 that I can use with my Mavic Pro drone. It would not be in WiFi mode, just GPS. Does anyone know if I’d have to add this to my AT&T account and get a phone number?
You would not need to add it to your account.
Are these GSM only on the unlocked? Will they work with Verizon?
Only AT&T and GSM for this one so no Verizon.
These will work with all GSM CARRIERS
