I am using Android phone on Verizon now. Last weekend, I got a present from friend "ARCCOS Golf" system which only works together with iPhone 4S or later. I contacted ARCCOS support center and got the confirmation of "Unlocked iPhone 4S" can be used for Wi-Fi only (without contract) mode which I bought from Amazon.com and tried to start the iPhone 4S. It was stuck on "Insert SIM" but I do not have SIM Card nor I do not know how to insert it etc. Please help me!!! Thanks, S H Keum
Just a get a dummy SIM card off of eBay or maybe even from Verizon. Also look on the left side of the iPhone and you should see an oval indented with a hole in it. Stick a paperclip straight in and the tray holding the SIM card should pop out. If this isn't clear enough, I'm sure there is some YouTube videos on the subject.
