I recently sold an extra iPhone 5C that I had after switching to the 5S. The phone was deactivated on my line, find my iPhone turned off and restored to its original settings etc. Now the seller is upset with me because I didn't mention to them that a SIM card would be needed to activate the iPhone and has to wait until Wednesday to receive one from Sprint. I guess I could have and probably should have mentioned it but I didn't think about it being that the buyer basically seemed to know all his stuff regarding activating the phone except apparently that a SIM card is needed. Any other way that he can activate it without a SIM card? I've got new problem trying to help him find a solution but I do not appreciate my integrity as a seller being insulted especially when at this point the activation process is out of my hands.
