I've run into a setback I've just got this phone audiovox CDM-8910, and so far I'm wowed by what it does, but my question to you all if you can answer it. I try to send a photo to another phone of the same make and model even the same carrier, and when it tries to send the photo, an error message saying "express network not activated" and the message doesn't get sent out. is this somthing I have to do, or is it on the carrier's hand?
