For the past several weeks my phone keeps dropping service and all I see is SOS, same thing for my son and my husband’s phone. We have different phones (Apple and Samsung). If we turn on the phone on airplane mode or turn it off and then back on it will pick up a signal but it doesn’t last for long. It’s super frustrating as we miss calls and texts as well. For 300 bucks a month we should have service. Does anyone have a fix for this??
