So far Verizon is ok inside buildings, but I wonder if the Motorola V265 or A670 (both with the extendable antennas) be able to hold onto a signal better inside buildings than the VX7000? The assistant manager that sold us these phones said that the A670 and the V265 antennas wouldn't help one bit. Is this true? I wonder if Alltel would be better on my campus? Or would it be the same due to me roaming on their network for free? I will have to perform further tests. Thanks in advance for anyone's help.
