Unlike many of the threads here about using an unlocked phone for data over wifi without a data plan, my issue is making cell calls over wifi. I have had trouble tracking down a sufficient answer via carrier websites and through contact with my current cell carrier. I have the TMobile Hot Spot @Home service, and the companion cellphones that work with a wifi signal for making calls (I use a Blackberry Pearl 8120 and my wife uses a Samsung Katalyst - note: this is NOT regarding the VOIP service that TMobile provides for home phones). However, TMobile no longer supplies cell phones that work with this service, and I am at the end of my contract and looking for alternatives. My problem is that I live in an area with notoriously spotty cell service - which makes the capability of making calls over a wifi signal in my home a critical consideration for me.
Do you know of other carriers that provide a service similar to the Hot Spot @Home, and whether there are any comparison reviews from outlets like CNET to help with decision making? And short of that, do you happen to know whether some of the newer phones that have wifi capabilities allow calls over wifi - or whether the wifi capability is limited to data?
Not sure if there are many others in this similar situation - its likely why the @Home service was discontinued. In any case, I'd appreciate any thoughts you may have. Thanks in advance.
