I was recently advised by AT&T telecom that my new, unlocked, international Android phone, purchased here in BA, is incompatible with AT&T's U.S. network. This presents a significant problem namely; that I now cannot receive SMS verification codes (from my bank and credit card companies) sent to my AT&T Florida based number. I cannot even port that number to GoogleVoice. And the physical incompatibility precludes any enhanced AT&T data roaming or WiFi calling solution.
I have researched the issue for countless hours and am now at my wits end. Is anyone aware of a work-around to this situation? Perhaps some type of VOIP / landline hybrid service offering? If yes, your advice and suggestion would be greatly appreciated.
Sincere thanks in advance.
