Hello all. I have the Samsung Galaxy S2 with Virgin Mobile as my provider (both of which I've been very pleased with up until this point) that out of nowhere has lost all signal. I can still get wifi and it works, but mobile data is "searching for service" everywhere I go. I've taken the battery out, put it back in, nothing. Restarted the phone, nothing. Tried airplane mode, nothing. I've seen removing the SIM card and putting it back in as an option, but this model does not have a SIM card or is embedded into the phone, one or the other. Any suggestions? Thanks
