No one has solved this problem and people have been trying to figure this one out for months. If you just purchased this phone, I highly suggest that you return for a refund if you still can. The HTC Panache has horrible/weak signal strength which is compounded by the disappearing network. No one has conclusively proved that the problem is with either the phone hardware, the phone software, the network, or any other factor. It's probably a combination of all those things. All we know that many Mobilicity customers are having serious problems with this model. This problem is widespread.
