AT&T(Onyx) or T-Mobile(Driftwood)
Looking forward to switch a wireless carrier from Verizon for Onyx or Driftwood. Which carrier do you recommend to get most out of 9700 device? I’m quiet confused with the VoWi-Fi (UMA???:confused:) support thing.
Please correct me if I misunderstood anything.
• Both Onyx and Driftwood devices are Wi-Fi enabled, can surf Internet with WAP connected
• Onyx can NOT make a phone call via Wi-Fi no matter what, it’s disabled by AT&T
• International calls will not be charged as long as call was established with VoWi-Fi (UMA)
Thanks ahead of you help and advice!
