The manager at metro by t-mobile said that my phone won't work on metro by t-mobile service because they're an mmo? My phones a cricket s10 galaxy cricket was at&t signal. I need all my services to work either way if I went that route. Currently have the nord as a backup sure through them. My phone is also unlocked as cricket gave the unlock code. If it's unable what's the best deal, besides cricket to keep my s10 up and running?
