So I put the new TING SIM card in and the S9+ automatically downloaded the carrier info (Sprint). Then I went on the Ting website and entered the IMEI and SIM Card number. Got right to the last page and hit confirm but sadly, I get a "SIM card is not compatible with this device" response. The phone shows all the correct SIM card status (Sprint, in-service, CDMA, etc.); how it cannot be compatible?
