schmidtj Posted March 27, 2020 Share Posted March 27, 2020 I just want to activate a used Iphone 7 on an existing line. Checking the Sprint site I have determined the SIM part number is SIMOLW506C. I have found that there is either a big letter A or C on the SIM credit card sized thing. The UPCs are identical. So what is the difference between a SIM with a Letter A and one with a Letter C? The Sprint site refers to these letters as SIM Identifiers. Thanks, J Quote Link to comment Share on other sites More sharing options...
