IPhone – trying to unlock iPhone 5c

here is the thing most of the answers work for those who have shsh blobs saved before but the thing is what if one has accidentally upgraded his/her iphone to the newer version and unable to activate it. in my country it doesn't work but he easiest way to activate your phone even without sim card is to call an emergency number like 911 or 112 and before you hear any voice press the power button and then on the notification bar area click again on the phone icon and hangup and you will see your home screen and well the rest is the rest.for video help search something like " Activating iphone with out sim card" on youtube. hope i contribue something and sadly i couldn't get mine to work.

There is another question and answer thread that explains the issue in more detail, but for all intents and purposes if you purchased a CDMA iPhone from a carrier then you will be 100% out of luck; you simply cannot use another provider’s SIM card.

The only way you could ever expect to use a CDMA iPhone with another GSM network is to get a factory unlocked phone directly from Apple. But if you get any CDMA phone from a provider like Verizon, Sprint or Virgin Mobile you are basically locked into their CDMA network. No chance to just pop another carrier’s SIM card in there to get GSM service from someone else.
