It just randomly looses all signal.  If it toggle airplane mode on then off it works again for a few hours.  I took to the t-mo store and they gave me a new sim card.  But that didn’t help.

I factory reset the phone.  This seems to have helped with  the  frequency that it happens  but it still happens.  Just it seems to work for a 3-5 hours before needing a toggle VS before it needed one every hour.
