Samsung Galaxy S7 Edge - "Mobile Network Not Available"
HELP! My Samsung Galaxy S7 Edge worked perfectly until a few days ago, when text messages stopped sending. Then incoming/outgoing calls failed. Have tried the most commonly recommended fixes (airplane mode off, rebooted phone, checked for software updates; reset network settings, removed SIM card and rebooted, cleared cache in safe mode, etc.) Nothing worked. Want to avoid factory reset if possible. Suggested fix, please????
