There is no SIM card installed in the iPhone you are attempting to activate.
iPhone 3GS, iOS 5
Well, if a GSM iPhone, a sim card is required in order to activate it. So, do you have a sim card?
yes i inserted the sim card.... even though i am getting the same message..................i tried inserting another sim but no luck 😟
It's sounding like your phone is locked to a carrier which is NOT one of the sims you are trying.
I am using the phone more than 4 years. Initially I unlocked the phone...I didn't remembered How I did that. So please let me know...how can I unlock the phone
You mean you hacked your phone, & Apples's servers have detected such & now you're in the mess you're in.
If you want to fix this, get a sim card from the carrier your phone was originally locked to.
