Can't seem to go online when on a call, never had this problem with my G2, any fix?
Under this page you'll find how to enable and disable:
Advanced Calling 1.0 | Verizon Wireless
I'm pretty certain you have to have advanced calling activated.
You should be able to activate it on your phone, settings>advanced calling OR you can go here and log into your account:
Advanced Calling 1.0 - Verizon Wireless - Verizon Wireless
How is the call quality and reliablity on the advanced Calling?
You know I don't have mine activated, but seeing as the call quality as of lately has been rather cruddy I am considering it. I'm pretty certain if you activate it and it doesn't help, you should be able to disable it as well.
