Sorry if this has been answered already. but, I have the Behold II through T Mobile and when I'm on the road and in certain places I will have full bars but no 3g, or wifi. When I try to send a text it says "Unable to send text, will send once service becomes avalible" When I try to make a call it says service unavalible. It tells me I have full bars, and when I go to network selection, it doesnt matter what network i choose or whats avalible it wont connect to it, a message will pop up and say "Network with limited service avalible, search for network" ..if i say yes it just does the same thing all over again, and if i say no it goes into automatic mode and wont let me do anything once again.. I have full bars, does that not matter? If I have to have 3g then why would it tell me i have a full signal when I really dont.
