No. Okinawa has no GSM carriers, only CDMA.
Yes, you can flash a Verizon phone to ATT. However, you will also need to insert a Verizon SIM card into the ATT phone in order for it to properly work.
The sim card will only work in a different phone if the phone is ulocked, in not, no

hi i have a go phone att will it work in Guadalajara Mexico if it doesn't what prepaid company from the us work over there need a answer quick will leave in a month
Env would not work on ATT as the phone would not be compatible to the technology used by the carrier. Env is a CDMA phone, while ATT is a GSM phone, and these two technologies are not compatible with each other.
An AT&T Go Phone is a prepaid phone that you buy phone cards for and add talking time to your account. There is no contract for a Go Phone.
Att is a Internet , Cable , and Home phone company. There is no 1 thing that att does
yes u can I had my att go phone unlocked and tried to use my sim card from st. talk which I found out uses att service towers in my area however, it didn't work. It stated "sim crash"
Yes, provided your ATT phone is SIM unlocked.
Only if the T-Mobile phone is unlocked. If the T-Mobile phone is still locked, only T-Mobile SIMs will work.
