How to unlock Iphone 4 Verizon?

Hi,

My friend just bought a GSM Iphone4 Verizon from someone but isn't with Verizon. She does the no contract thing with a mobile company called Straight-Talk. (It's sort of like a pre-paid thing).


But I'm trying to figure out how to help get her phone to where it isn't lokced into only Verizon. I've heard that unlocking a phone can allow any carrier, but I've also heard unlocking only allows international carriers? Plus, we tried calling Verizon to ask for an unlock and they said no. So we have no clue how to get her phone to work...

Yes, Verizon iPhone4 is CDMA only--that is well understood.


What is not so clear is if a Verizon iPhone4 with a clean MEID can be activated with a different CDMA carrier such as Sprint.


Does a CDMA iPhone4 need to be "unlocked" to work on any other CDMA carrier?


It should be pretty clear that noway, nohow, nowhere is it possible to use a CDMA iPhone4 on a GSM network, and I'm not sure why there is so much confusion about that question. It is a completely different to ask whether an verizon iPhone4 can be unlocked, or whther that is even necessary.

That's easy... No. You can't activate it with a different CDMA carrier at all.

There's no such thing as an "unlocked" CDMA iPhone.

I just got off the phone w/ Verizon. They can not -- or more likely, will not -- unlock an iPhone4 CDMA. ***** to be us.

They literally cannot. CDMA phone's are locked in firmware, so the only way to "unlock" it from Verizon is for another CDMA carrier to reflash the firmware with their network settings and access codes. Verizon quite literally cannot do that, and no other CDMA carrier will do that (and in reality, none really have the equipment to do it nor do their customer service people know how to even if they had the equipment).

You apparently didn't get everything from this thread. If you buy a Samsung make sure you buy a 2009 model from Verizon. Then try to switch carriers. You will have the same issue. There are two major phone technologies in use in the US, CDMA (Verizon and Sprint primarily) and GSM (AT&T and T-Mobile primarily). In 2009 when the iPhone 4 for Verizon was released their were no hybrid radio chips so you bought a CDMA phone or you bought a GSM phone. You have a CDMA phone. The only other carrier you could use that phone with is Sprint but they don't accept carry in phones (including Samsung).


With the iPhone 4s, and other companies phones, in 2010, cell phones did have the technology to be both a CDMA and GSM phone. But if you had a 4s or a Samsung, or an HTC or a Nokia with Verizon then you would have to get it unlocked through them and it would olnly be able to use foreign carriers. You could not take it to AT&T or T-Mobile. This is Verizon's policy.


With the iPhone 5 and including the 5c and 5s the GSM side of the iPhone is unlocked and can be used with any GSM carrier, no unlocking is necessary. You still can't use it with Sprint though, they still don't accept carry in phones of any manufacturer.
