I've searched quite a bit and I saw a few threads that said that the Verizon GS4 comes sim unlocked. But I put in a friends Sprint Sim and I got an error message that said "non verizon sim." I also saw tutorials on how to go into the phones menu by typing *#06# or *#0011# but these do not work on my phone. Is there a code that will work on my phone? Also, do I have to install a custom ROM on this phone to get the sim unlocked? I really don't want to go that route but if I have to I will.

OK. I found out that you have to enable the hidden menus first. There is a forum here that talks about it. It's titled [how to] Enable Hidden Menus for Verizon Galaxy S4. And from there you can sim unlock.

This is true. I have put in an active ATT sim got "non-Verizon SIM" message and could still make calls and Internet from the ATT SIM.

I am currently in China and trying to get my sch-i545 to work with a sim card I purchased. While my phone is able to recognize that the sim card is there I recieve the message that the sim card is from an unknown source. Is there any way to fix this with the sch-i545 even though it is not the international version of the phone.

Are you rooted? Are you running a custom ROM?

This is only works with gsm. The cdma side is still locked unless you call Verizon and get them to unlock it.

Are they capable of doing this with the S4? Assuming they are, are you speaking theoretically or with certainty? Could you confirm via experience or perhaps cite the information?

Reason I'm asking I tried to use a non-Verizon sim once with limited success on an S3. Called Verizon to see if it was a sim-lock related issue and they insisted that the phone shipped as unlocked as could possibly be, which would contradict your statement assuming the same holds true for the S4.

That's interesting, but doesn't answer my question - that being about Verizon being able to unlock the S4 for CDMA carriers. I'm aware that it's GSM unlocked.

Sorry I misunderstood. Don't mention sim unlock to them since the cdma doesn't use the sim. There is another thread floating around here that mentioned this but I couldn't find it. What it boiled dien to was telling that you are traveling overseas and would like them to unlock cdma. This doesn't Guarantee that they will. Sorry I couldn't find the link.

Anyone ever call Verizon and had their s4 or S3 unlocked thru them before who finished their contract? If so can you explain what the process was they walked you thru?

Actually it's quite easy to do. You go on your My Verizon account, or call them and add the $4.99 international package. That does NOT include any data, only the capability to use it on CDMA elsewhere or the Global option on your Verizon Sim.

I recently traveled to Sweden and have used several different Verizon phones (with International SIM) outside the USA and not had issues.

The "Non-Verizon" sim message has absolutely no bearing on being able to use another sim in the phone, its UNLOCKED. If it's a GSM simcard voice will work no problem, data you have to add APN in. You cannot use a Sprint SIM because like Verizon they use authentication by way of ESN or IMEI to be registered on their CDMA network. So it just won't authenticate.

So you don't need to SIM unlock, it's already unlocked.

Adding this feature does not cost anything on my unlimited plan. Only if you want to add additional global data and voice rate plans does it cost to enable the feature.

OK so in that case how do we get 3g and higher speeds when using other Sims? I took mine too ATT they put in the sim and still wouldn't get more then Edge data, We also have a Ver S3 that we have on ST prepay and put in the APNS and we still can't get above edge data either. Here the thing, the s4 is global ready yet it still has some kind of lock to prevent data so has anyone ever contacted Verizon after theit contract to come about unlocking their device to use on other carriers? What is the point of buying these phones, if they won't unlock then for us after contact is up? It would still be there phone, seems were just leasing it cause we can't take it with us to another carrier. Any guide to get these unlocked for3g and data please?!!
