Verizon iPhone 4S SIM UNLOCK Tutorial

[MountainApple]

I got this done yesterday. The lady first claimed I needed to be a customer for 90 days, not 60. I said that's not what I heard, and persisted a bit, and then she agreed to "make an exception". After inserting a European SIM a few minutes later I activated (you need to be on Wifi) and bingo! I was roaming on T-Mobile.
The whole process went pretty smoothly and now I'm all set for my trip abroad!

I have a Verizon iPhone 4s and have followed the procedure to have the SIM slot unlocked by Verizon.

I have also received and activated a TRU micro SIM. Activation has been confirmed both on-line and via phone help.

A Verizon phone rep confirmed that my SIM slot is unlocked.

So in essence - both TRU and Verizon say they have done their part in making this micro SIM work.

But... I have a problem:

I activated my TRU micro SIM over the internet prior to placing it in my phone.

I confirmed on-line the activation had taken place.

When I removed the Verizon micro SIM from my iPhone it alerted "No SIM In Phone" - that's normal.

When I put the TRU micro SIM in my phone nothing happened - no search for carrier, no indication that anything had changed.

My iPhone still reports its on the Verizon network with the TRU micro SIM in the iPhone.

Is it possible the micro SIM is defective?

Have I failed to follow the instructions somehow?

Does anyone have experience putting a TRU micro SIM in a Verizon iPhone 4s?

I would appreciate any help. As it stands now I have a micro SIM that appears not to function in my iPhone and a trip to the UK in about a month or so.

Any help greatly appreciated!

PDCorlis,

Know the thread is a few months old but having same issue without getting a resolution from either Verizon or Tru. Did you solve your issue. I cannot get my activated Tru Sim to connect to a GSM network. I use CDMA and just want to know if the Verizon sim unlock and the Tru actvation are indeed working before I travel to UK for 2 months. Any help would be greatly appreciated. Was your sim bad or is it just the fact that Tru sims will not connect to GSM while in US.

Thanks,
Gazzer

Still reading conflicting information about this. Can anyone confirm this is possible and does it depend on the foreign sim card or company whether or not this can be proofed to make sure it gets a signal in the US? Don't care to use it just to make sure when I step off the plane at Heathrow it will work and that VZW did the unlock correctly and I am not missing a critical piece in a procedure I thought would be so simple.

Anyone out there experienced this?

I called Verizon and was told that they had unlocked the phone, but that I had to complete the unlock with iTunes after I left the US. When I put in an international prepaid sim card (still in the US), I get an error message that it is not compatible with the iPhone. Anyone have this experience?

If verizon informs that ur fone is unlocked, there is a very easy to confirm this. Get a gsm sim (not us), connect ur phone, restore and update to latest version of ios available. Once update complete, u will get congrats message

Did you have a wifi connection when you put the international sim in? You need to be connected to the internet when you first put in the sim.

I know there has been a lot of question of whether the Verizon iPhone 4S could use a US sim card when unlocked. I know for the world BlackBerry phones, when it was sim unlocked you could throw in an AT&T sim card and use it here just fine, 3G and all. Technically it would be possible to do the same with the 4S. Whether they've implemented some kind of software block or something has yet to be seen. I would guess not because it all goes by GSM bands. Can't wait to find out.

I am using a Verizon iPhone 4S on T-Mobile USA Network. I can can say it will also work on AT&T as well. CDMA iPhone 4S has 2 plist files in every US CDMA iPhone 4S's. Mine had one for Sprint and another for Verizon.

I backed up both and removed them from their original location on the phone's file system. With that being said needless to say youd need a jailbreak to find those files.

Removing these files will disable the CDMA transceiver and default the phone to ALL GSM networks--including USA GSM networks.

Can you give any more details on what jailbreak you used for this? I posted to another thread about how we're waiting to see if Verizon unlocked the phone. Most likely, as noted by another poster, it wouldn't work on T-Mobile. I was thinking we'd try it first, assuming that it ultimately does get unlocked. But, we might try one of the jailbreak methods.
