its odd too TracFone went to Verizon ,so you need new simm maybe and 2 of mine possibly became unlocked
My friend who is ex-telco said that in some cases, it was expensive to pull the 2G equipment out so it is on a low priority. Also I believe there are cases where you just can’t switch it off without reconfiguring things.
Oh my gosh how do you know if you have a 2G or there 3G? As I’m going through my old phones I don’t think they’ll work cuz they are US Cellular & don’t have a SIM card at all
