SIM Not Valid for iphone 4s?
I bought an unlocked iphone 4s off of ebay (software is up to date). I bought a straight talk sim card, put the sim card in, and went through the activation process- but it still gives me the message "SIM Not Valid - please insert a compatible sim card"
the description of the phone on ebay specified that the phone s unlocked and compatible with any GSM carrier
PS i found a verizon sim card when i opened the phone…
It sounds like the phone isn't actually unlocked
I agree, the phone does not seem to be "unlocked", email your eBay seller
Could be that its not unlocked, or maybe sim card is incompatible, Verizon runs on CDMA network, while ATT, and Tmobile run on GSM network so the sim cards are not the same.

- Would my iPhone warranty be valid? I have an iPhone 4 that stopped working. If there were no signs of water damage, would Apple have to replace it even if it's no longer under contract with AT&T (I have a 4S now.)?
- What does sim not valid mean on iPhone 5? What does this mean? Because the phone carrier on my phone is EE and they recently sent me a new SIM card for my iPhone 5 and they have to activate it and they said I have to wait for it to be activated so does this mean that it isn't activated or does it mean something else?
- SIM not valid for Iphone 3 My iphone broke so my brother gave me a used one that was on the Rogers network that his friend didn't use anymore, I'm under contract with Telus, I put my SIM card in the phone and brought it back to factory settings and then it says SIM not valid. What can I do to fix this so I can use the phone?
- Should FBI be allowed access to encrypted iPhone data when the they have obtained a valid search warrant? Should the FBI be able to force Apple to create an override for the delete after 10 wrong password entries feature on the iPhone to allow the FBI access to encrypted data when the FBI has obtained a valid search warrant?
