    My 9810 cannot receive and send calls and text messages after installing battery booster free. The signal keeps switching to sos. I do receive bbm messages and I can still browse smoothly, when the red sos sign does not show. What can I do? I have already uninstalled the battery booster free, but I fear that it has already changed settings in the phone.

    Edit: Will a factory reset work?
    Edit: Did a security wipe/factory reset. The problem still persists. I can do data and bbm, but I cannot make or receive voice calls or text messages. The sos radio signal keeps interrupting the H+service

    in short... i would take it back or utilize your insurance if you have it. that doesnt seem right especially after you did a reset.

    It might be that your SIM card isn't connecting solidly in its holder, try a different SIM card
