Does the XA support VOLTE? The whitepaper on Sony Mobile's site states that the device does. But I am on T-Mobile US network and calls drop to UMTS/HSPA(3G). Sony support says the device does support VOLTE and I need to talk to carrier. Carrier says if the device supports VOLTE it should work. Nobody is giving good support. Does anyone know?
The Xperia XA is VOLTE compatible as you can see by the whitepaper, however it is up to the network to enable it. If you purchased your device unlocked or from another network, the firmware may not have VOLTE enabled. You usually need to the operators firmware to use it.
Thank You for replying. The device is F3113 unlocked from BestBuy store in the US. T-Mobile says the device only needs to support VOLTE. There is nothing they need to do on their side. I have a Moto X Pure Edition that is unlocked and purchased directly from Motorola. VOLTE works on this device with my sim card. But when I put the sim card into the XA(F3113) VOLTE does not work. Does this device support VOLTE or not? I need a clear answer so I can decide weather to return it.
Does Sony have proof that my specific model supports VOLTE? I do not see the option to enable VOLTE or Enhanced Calling as it is called on most phones. I need more support if I am to keep this device?
Your network controls volte, not sony. The device supports it but some networks insist the device has their firmware, or other settings... There is literally nothing Sony can do to activate volte. All troubleshooting and diagnostics on network services need to be done by the network.
