We have switched our account to the new FLEX plan and one of our phones has problems with calls not coming through and delayed text messages. This phone worked perfectly prior to the switch. We have had Ting Support push updates to the phone, reset, powered down & up numerous times. Will a different SIM fix this or will we be required to purchase another phone (we have had to buy two so far). Please help. The phone in question is a MOTO G4 Play.
Thank you for anything you can do.
