awabout a week ago this error started appearing. I never dried the phone or anything it just came out of the blue. I've already taken out and put back in the sim multiple times, reset the phone completely and cleared some network data I was told to erase from a woman on sprint chat. since I'm assed my 14 days for a switch what could I possibly do?
i have seen this error a few times mentioned in these forums. at times it ends up being the sim card itself..other times (much more rare) it ended up being the sim card tray itself..you will have to take it into a sprint repair store in order for them to really figure out which of the 2 it might end up being. if memory serves there isnt a way to erase your info on the sim card..the sim card is NOT the same as a sd card.
Thanks for posting. Did the chat representative verify the sim card number matches our system? Do you get 4G LTE at all? Please let me know.
