Samsung Galaxy S6 SIM registration
I have a BYOD Sprint locked Galaxy S6. I purchased the required SIM and completed the BYOD activation. Everything works on WiFi as expected. I can:t get cellular data when off WiFi. I found every article I could find, used the diagnostics app, did several carrier resets. When I reset I get a Sprint activation that indicated I am an existing customer trying to swap SIM cards. I attempt to complete the process but it asks for a phone number (the what's this link says it is a Sprint PIN) and everything I try fails as an invalid phone number. Can someone help me get my SIM and device active for cell data please.
