I've not dabbled much into this, so forgive me if my ignorance is too overwhelming
In the last week or so I've had luck using friends SIM cards in my phone. Both were serviced by ATT. Then I tried it with a pre-paid SIM that belongs to my grandparents that has plenty of time on it. This however, does not work. It just says Searching constantly. I've also tried it in my unlocked G1 (actually got in touch with T-mobile and obtained an unlock code) and I get the same.
This is of particular concern to me because I will be leaving the country in about a month and I'd really like to know if it's going to work at my destination. Is there some other setup I need to be doing that differs from a regular sim to a pre-paid sim?
Was it a Boost Mobile prepaid? Those are known to not work, due to the network they use.

I was told it's through Net One, which I've never actually heard of. Wonder if that's why it doesn't work.

I can not get the nvm folder unlocked on the 9k port. I do need it unlocked to be able to write the data settings and have them stick, correct? Also to change the MEID? I have CDMA WS 2.7, QPST 366, DFS 4.0.0.4. Can anyone help?
I am trying to flash this phone to cricket-
I do have 1x data with a AT&T sim installed. Text and calls work.
I also have 1x data with no sim card installed, but I can't make calls.
Yes I am trying to unlock and edit the 9k port with the vzw sim in the phone.
Edit: 'open sesame door' DOES NOT WORK
The radio itself ia the problem. It doesnt work at the frequencies that at&t operates on. Yes it does have a sim but it isnt the same as a sim that is in an at&t phone.

CDMA doesn't use sim card. Sim card is gsm by default. The one on the tbolt is not a "sim" as we know it. Im pretty sure it I for 4g LTE only. Everything else should work, yes 3g cdma, without it present. I think it is a UIM card. I have heard Verizon is using it for CDMA authentication as well, but I am not sure on that one. CDMA does not need a "sim" card, but a carrier could choose to use a UIM or any hardware key if they desired. If you aren't on Verizon's network, it should be 100%. If you are(even through a third party carrier that uses Verizon for their cdma service) you will need a new card. Once they are issued, they get tied to the account and phone number and cannot be changed for security reasons.

So you are saying the data fields on the 9k port are irrelevant to my data issue. All the NV items on 9k port still have Verizon information, so the UM and AN User ID and so forth are all the old Verizon information. I can NOT write to these fields, from what I understand this might be the reason I am not getting 3G.
So if those settings are not needed, is it my Radio? Like I said all my calls, texts, MMS even all WORK. My only issue is 1x Data, I can't seem to get 3g.
ALSO WHEN THE VERIZON UIM/SIM CARD (WHICH EVER IT IS) IS IN THE PHONE, I HAVE NO DATA AT ALL, I ONLY GET DATA WHEN I USE A SIM CARD FROM ANOTHER PROVIDER.
THE DATA WORKS WITH NO UIM/SIM IN THE PHONE, BUT WHEN THERE IS NO UIM/SIM I CAN NOT MAKE CALLS.
Have you seen this article? You are correct with your approach, this may help you.

Anyway if I were to switch to tmobile, can this phone be used or is it completely impossible? Other countries use gsm networks only so being a world phone I would assume that it can be used with US gsm networks. Thanks.

Okay did some research and youre correct. Invalid sim pops up when a local sim is inserted. Lets say I flash the google edition rom stock rooted. Now I know it will mess up all radio with cdma but will this bypass or does sprint have a hardware lock on the device?

Yes, it will work on tmobile for text and call when you unlocked it. For data, you need to change the apn setting to epc.tmobile.com. I am sure that you will get EDGE but not sure about 3g/4g or LTE.

You can't do it, it is impossible. Sprint has US carriers blocked and there is no method to unlock to use a Sprint phone on Tmobile. So here is the steps to follow: List your Sprint phone on Ebay or Craigslist, Sell it, go buy a Tmobile S4, enjoy.

There seems to be a very dismissive attitude in this thread.
I have a Sprint HTC One and I can easily throw a T-Mobile SIM in there and get full service (sans LTE) with T-Mobile. The HSPA+ is faster than the Sprint 3G.
So while I do not have personal experience with the S4 in this fashion, I do not see why it would not be possible to get it unlocked and used on T-Mobile. (Unless Samsung/Sprint are blocking it for whatever reason)

Just check the sim card. A USIM means the Sim card does the LTE authentication while the device does the CDMA authentication. A CSIM means that both LTE and CDMA Authentication comes from the sim card and you can hot swap devices by using the sim card just like the Iphone 5s/5c which uses CSIM.

USIM .. like most current Sprint devices. So most of the provisioning is still done in the EFS.. unlike the 5s which relies entirely on the sim card.

Sounds like maybe LTE 2600 (B41) hand off issues between the different LTE bands that is causing the delay. What does this phone being an exclusive triband have to do with it? Obviously the demo units are already available so the phone must be done. I doubt it is due to production issues since LG shouldn't need to make as many phones at launch like Verizon or ATT do. Doesn't sound like it makes any sense to me. Oct 25th would have already been pushing it.

That seems to be my guess that Sprint is waiting on the LTE 2600 network to be built out a bit more before launch. But it also could be that Sprint can be having LTE 2600 TD-LTE to LTE 1900 FDD LTE hand off issues that is causing the delay.

Call the international department and tell them you plan to go to Europe soon so you need to unlock the phone. They will send a update to your phone. You can check by setting a international Sim or even an ATT or Tmobile Sim into the phone. If it shows "no sim inserted" then it was not correctly unlocked.

From what I was recently told... yes. May test this soon myself.

Call the international department and tell them you plan to go to Europe soon so you need to unlock the phone. They will send a update to your phone. You can check by setting a international Sim or even an ATT or Tmobile Sim into the phone. If it shows "no sim inserted" then it was not correctly unlocked.

You mean Asia,not Europe
One additional question for you patient souls: once I've got it all unlocked with (hopefully) the sim working correctly, can I just leave the sim in the phone and switch between the CDMA & GSM modes or do I need to actually remove it when I return to the US and back to Sprint service?

The Sprint sim is required to receive LTE so yes, you must put the Sprint sim back in and reset your APNs for Sprint.

Thanks. I've been doing a lot of reading about the Spring S4 with international Sim and see a lot about needing to manually edit APNS to get data and that one needs to be rooted to do that. Is that so? I am not rooted.
There are apps in the play store that can add the APNs for you automatically. Not sure if you need to be rooted to use them though. Search the play store for APN apps and the descriptions will tell you if they require root or not.
