For someone that will want to use in both Thailand and USA, will the US version work fine in LOS?

 

Using T-Mobile in USA.

 

US GSM Model:
GSM/GPRS/EDGE (850, 900, 1800, 1900 MHz)
UMTS/HSPA+ up to 21 Mbps (850, 1700 (AWS), 1900 MHz)

Global GSM Model:
GSM/GPRS/EDGE (850, 900, 1800, 1900 MHz)
UMTS/HSPA+ up to 21 Mbps (850, 900, 1900, 2100 MHz)
 

Looking at those basic specs. It should work on 850mhz 3g . Probably the best network is True. Obviously the global one would be better.

T-Mobile offers 2G free, so it would only need to work on the 2G network really. not even sure what frequency that works on.

 

Seemed to work OK on my Moto G LTE @ 2G with AIS once I set the phone to that.

 

This is for a friend that wants to use in US and Thailand, I think she would be better off with a Moto G LTE.

 

I think she will keep her T-Mobile SIm in the phone.

 

Thanks for the help!
