I am not certain we can help. If your carrier doesn't support the protocols that your phone understands, there is NOTHING WE CAN DO!
Please understand, I have not and will not look up the specifications of your hardware. What I do know, is, if your "device" wishes to connect to the modern network, it must speak the language (PROTOCOL). You know, like PROTOCOL DROID in STAR WARS!!
It sounds as though your DROID speaks a very old language that the modern network no longer supports!
We can do nothing about your carriers network or lack of support! Lack of your carrier support is what this comes down to: If they don't support it, neither do we!
