I want to use a SONIM XP3300 FORCE UNLOCKED PHONE in the USA, mainly in Southern Arizona. I am confused about what carriers will support this phone. Will any of the major service providers support this phone?

Thanks!
Sid

AT&T and T-Mobile are the GSM networks available in the United States. There are also other providers that use their networks. If it supports AT&T or T-Mobile's frequency it should work fine. You need to purchase a SIM card and insert the SIM card in the phone.
