We are very disapointed with this phone. In March, 2006 we switched over to T-Mobile service, got three phones, two were RAZR V3's. The problem, NO SERVICE in any commercial building. If it were just one of the RAZR phones we would have it checked out, but both phones DO NOT WORK inside buildings. We have trouble at times getting service in our own house.We had talked to several people who use T-Mobile and were impressed by the package and service available so we switched. None of those people have a RAZR phone, and none have any problems with reception anywhere. The third phone on our plan (Samsung), has no difficulty getting reception.Don't waste your money on this phone or at the very least, don't plan on using it inside.
