I have a Samsung Galaxy S20 5G AT&T unlocked smartphone on TracFone service. I can't send or receive text messages from my sister, dad,or niece. I have contacted TracFone and they said that there isn't any problem with the network. I can send a text message to myself and receive some from TracFone. Do you think it is the phone itself that has this problem? It started on May 30,2021 after software update to Android 11. Any help will be greatly appreciated!! I have unlimited call and text messages!!
