Hi guys, i am a VZW customer using touch pro 2, I am on business trip in Uvalde TX, there is no VZW service there I am on extended network and I am getting a very annoying worning on my phone it comes almost every 5 sec or even less, the worning is " Device is regestering on a voice service only network. Data services are currently unavailable" how can I get rid of this worning, I keep clicking ok and it will close for few sec and then comes back on, I tried to turn data connection off and almost disabled any program that use internet but the message is still pop up every ew seconds. can someone please help me with this issue.
