Hi guys. I put up in California and I have a Vodafone connection with me at the present. I have seen that the 3g signal quality of my network is not really good. I think that this is the time when I do change my service provider. What about the at & t? How is the at&t 3g coverage? What will be their plans and pricing like, when it come to the 3g usage. Please tell me all that you can, so that I can get an expert advice in this case. help me in being an intelligent buyer. Thank you.
