Hi I have a HTC ONE MODEL: HTCPN072. It is a sprint phone I just baught on the web. The problem I have is that the cellphone cannot connect when ever i put in a Jamaican SIM Card in it. When ever I put in a GSM sim card it is saying 'Invalid SIM CARD. 4G service are unavailable as the sim/UICC is invalid'' I dont know if u can Help me please because this phone is a brand new one!
Can this phone be used in Jamaica? on 2G and 3G networks?
How do I know if it is a GSM OR CDMA mobile phone?

Is the phone sim unlocked? I don't know how it works with Sprint but that would be the case with GSM providers
If it's Sprint, it's CDMA.AT&T and T-Mobile are the only GSM providers in the US. However, it should work there if you get the SIM unlocked. The SIM unlock code is formulated based on the IMEI, so there are three ways to get it:
From Sprint. Probably the simplest, but tricky if you're not the phone's original owner.
Pay a site or unlocking service with the algorithm that decodes it from the IMEI. Usually runs around $10-$20.

You can also try this app, but it only works on rooted phones running the original ROM:

Good luck.

Bro, A CDMA PHONE CANNOT BE UNLOCKED. IT WON'T EVEN WORK ON ANOTHER CDMA CARRIER LIKE VERIZON. ONLY SPRINT SIMs WILL WORK.
Make sure u buy a GSM phone if u plan 2 use it on another carrier.
But the phone uses GSM! It picks up the network here but I just cant get the unlock box

Then it simply isn't a Sprint handset. CDMA phones can only work on that particular network. The phone is custom-made just for that network
Has anyone been able to SIM / network unlock Sprint variant of LG G4? For international use? for domestic carriers?
The phone appears to be locked. I tried putting GSM micro SIM and putting phone in to GSM mode. Got an icon about invalid SIM in notification tray. But no prompt to unlock. Also no menu in settings to unlock via network like my note 3 had. Even worse, no menu to select GSM Network operator in the settings.

I know , that is the theory, I am curious if anybody actually tried it. I am concerned about the fact that I don't see a menu to select GSM network, which was there in Note 3
it almost looks like the phone can roam on GSM network using Sprint SIM, but all the menus that would allow presence of different SIM where removed.

that option is just hidden, when someone get the phone unlocked the option in the menu will be enabled, are you inside USA
I did try a Simple Mobile Sim and it worked just fine. Have you tried any of the movs from Att or Tmobile??

Friend called Sprint and they unlocked his phone OTA. Now when non-sprint SIM is inserted it no longer complains about invalid SIM, however it will not connect to any networks in USA and still no way to see a list of networks or do a manual selection of network. That menu is still missing. I suspect the phone will now work outside of the USA in automatic network selection mode only, which may not be a good thing some times.

Doesn't matter what you try, you cannot use Sprint's phone on AT&T T-mobile here or any US GSM carriers. When sprint unlocks it for you, then you can use it outside of US on GSM Networks.

You must be new here. Domestic gsm has been unlocked on most modern Sprint smart phones. Just in the years I've been with Sprint ive unlocked the Moto Q, G2, S4, and now the G3 for ATT and straight talk. Ive read of several others having the same ability. The s5 can also be unlocked but only one guy knows how but you gotta pay him for it. Kinda ****ty but it actually works.

You didnt listen... Sprint phone works 100% for att.. They jt blocks it at the software level... But my friends has unlocked all the newer sprint phones till now.. I dont see why he shudnt be able to do it here
Any chances of unlocking when outside US? I got my phone from Amazon and got it shipped in my country. Tried calling them but they said they only unlock activated phones. Also tried various sites that offer unlock codes but since G4 is not asking for unlock code, they can't do anything.
Do I have any other options?
For those still trying to unlock, I've followed this post for unlocking the G3.
http://forum.xda-developers.com/sprint-lg-g3/general/sim-unlocking-ls990-zv8-t3083567
And I can now accept calls, will try it out some other time if I can get data as well.
Note: Make sure you have the correct permissions on the files that you'll copy.

I can't confirm, since I don't have access to any AT&T SIM at the moment. If you're already rooted, you can try it out, but make sure to back up the files.
Another update: After updating the APN, my data finally worked. LTE is impossible at the moment since the this doesn't support the LTE bands here in my country
Warning: Don't try to disable auto activation for now. I got the Security Error and still on the process of fixing it.

Internationally.
!!!!! i got it working on at&t!!! calling and sms work..I dont have data so i can't test that...ending a call gives issues as it hangs there for a bit!!!
I have the Sprint LG G4
I also got the unlock code from Sprint. But I can't get the phone to ask for the unlock code. Any hints. Can I force it to ask?
1) My friend (U.S.) gave me (Canada) a T-Mobile Galaxy Note 4. I am trying to use it with Wind Mobile.
2) He claims that T-Mobile performed a carrier unlock, which seems to be confirmed because putting a foreign SIM card in does not ask for an unlock code.
3) My Wind Mobile SIM can't register on network. I tried a Rogers SIM as well and a different Wind Mobile SIM and they didn't work either.
4) The Wind Access Point Names have been entered, but manually selecting the network does not work either. It just says "Unable to connect, try later".
Am I missing something here? Is there another type of lock I need T-Mobile to remove? Do I need to flash the ROM? Thanks in advance.
If same sim cards work in other phones i would think that phone is blacklisted. On the other hand nowadays tmobile can issue temporary unlock codes for international travel. I dont know if Canada is considered international or not. Tmobile will permanently fully unlock device when paid off.
I have the SM-N950F and I can't call or connect to 4g on the MetroPCS network I've tried multiple APN's but nothing works, when I try to make a call it just says not registered on network.

MetroPCS uses T-MOBILE networks just like Cricket Wireless, my current carrier, uses At&t. Have you tried any sim card from any other carrier to see if it's a problem with settings or with the sim card itself?

Disregard this step because you have exynos.
I have it working for metropcs. Follow the guide for changing carriers and then use the "TMK" mobile code. I'd recommend the unlocked firmware (xaa) or else you'll flash tmobiles with all the bloat.
You will also need to call metropcs from a phone that you are not switching the sim on. They will ask for your imei number and switch it over. The sim cards used by metropcs only work for the phone that it is registered to.

Thanks it's working now.
I purchased a used galaxy s10 G973U from someone who bought directly from samsung.com unlocked version. he used it with tmobile. Now im trying to activate with sprint and it wont let me. Network sim setting show that sim is unlocked. Im trying to activate my phone on sprint website and it says "This phone can't be activated
Sorry, but this phone can't be activated with Sprint service. Try to re-enter your IMEI/MEID or try another phone."
I thought this phone is supposed to be able to be used with both gsm and cdma network carriers. what are my options besides trying to return it?

Did you contact Sprint and get a sim kit sent to you? You'll have to do that and then it should work. If it doesn't after that, I'd initiate a chat with them through the support page on their website.
Another option is to go to a Sprint store to activate it. They will have the sim card available for it. Im using an unlocked model switching between carrier and carrier-free firmware no problem.
(PS, once you do get it working there's a way to enable hotspot support without it on your plan.)?
