Is it possible to unlock a CDMA iPhone 4S (from Virgin Mobile) to use another SIM in it?

Question

My friend has an iPhone 4s, it was bought from in the USA from Virgin Mobile. I want to do a factory unlock (unlock the SIM). I already know how to jailbreak, would jailbreaking work? Any help would be appreciated.

I read this answer, but was told the following:

Virgin Mobile USA iPhones are CDMA. If you need a refresher - CDMA means the phone is locked to the network forever.

You will never be able to unlock your iPhone from Virgin Mobile USA. They do not use sim cards - so there is no way to unlock it.

Is that correct? My question is, is it possible to unlock CDMA iPhone 4S from Virgin Mobile?

Answer 1

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.

Answer 2

Of course, it's possible!

Simply buy a Gevey Turbo SIM ultra S CDMA. Note: type "geve" into google and watch it autofill with "gevey sim". Good news- You're in luck because the price is not bad for the CDMA Gevey SIM turbo at this time.

sometimes, they're close to $100. only $35 right now.

also, i've included some other links to help explain

Answer 3

Unlocking a CDMA phone is a touchy thing. CDMA means no SIM card, so you are mainly stuck with another CDMA carrier, and most of the time, they won't be using the correct bands for you phone.

In short: not worth it, you won't be able to change to another carrier with it

If you are certain that your future carrier runs CDMA networks and uses bands that your particular phone support, then go for it.

Worked with my 4S as well.
