I've had my Helio for over 5months now the Ocean. I know some people were having problems with their Ocean however,mine has no problems at all. And the Oceans being sold now have a firmware update so most problems have been fixed. I'm am very pleased with the service. I had Tmo and USCellular and they both had a problem working in my house. I don't live in a rural area so I don't know why they wouldn't work, however Helio works just fine with full bars!!
