Okay, so I'm pretty sure when I bought this phone with contract it was network restricted.. I changed my carrier yesterday to t-mobile, so I bought a sim unlock on the net. I received the SIM unlock code, I couldn't get to the input field though (I'm on CM10), but then I was playing with settings and I could successfully connect to T-Mobile, however the signal is weaker than it was before and it has disconnected twice, but still.. so I don't need the unlock code no more am I right? It was cheap so it doesn't matter, I just don't understand how can this phone can be unlocked.
Just curious, what was your original provider? I don't know specifically about T-Mobile, but some carriers allow other SIMs to be used, because they are sharing networks. For example, if you have a locked Rogers phone in Canada, you can use it with a SpeakOut SIM, because SO is riding on Rogers network. Could it be a similar situation for you?
But it's strange that you don't see a prompt for a network lock code when you insert a non-original SIM... I also had to unlock my phone by code, and I got the prompt right after putting in a different SIM. Could it be because you are on CM ROM? A general recommendation is to always unlock you phone from a stock ROM, before flashing a custom one. I am not sure about this, but just thinking out loud...

I was on Telenor Hungary, now it's T-Mobile, they are whole different providers, no relations at all. Well yeah, I've thought about that stock ROM thing too, but I still don't think it would connect to a different carrier because of the custom ROM. But it works strangely though, couldn't set up mobile net yet, and when I was on the T-Mobile hotline, it disconnected and the phone said the SIM might be corrupted.
So I tested, I can make phone calls, but everytime I reboot the phone I have to connect to the network manually from settings.. So I'm gonna try with stock ROM, and use the sim unlock code. Can I also use stock-based ROMs? Thanks.
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?

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.
Try the steps in this thread:

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

Good luck.
How do i go about unlocking the Sim? I cant get the unlock box where I put in the code to come up!

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
I have this HTC Desire 510 Sprint Phone, it has the SIM slot but in they said me that is only for the G4 connection.
Thanks in advance

tap phone and open the dialing pad an hit *#*#4636#*#* then tap Phone information and scroll down to "set preferred network type" in there you'll find a way to switch to LTE/GSM but I don't know if it will work unless the phone is S-off or already carrier unlocked.
Hi! thank for the responce.
My phone carrier is unlocked, i do what you said, then restar the phone, then put the SIM pin and a pop up message appear "Unlocking SIM" wait for 30 minuts and nothing happens, the little popup window remains there, the only way to take it off is pulling off the SIM.

So does mine and it's also CDMA and from what I know the CDMA phones cannot be unlocked from the carrier to use another network and the only one cable of doing that is the GSM phone not the CDMA ones. So mines still locked to Sprint and I'm s-off too.

If you want to get s-off, and your phone is 32 bit and NOT 64 bit, you can go to the website ---> The Root Ninja and download the app called Sunshine that @jcase made specifically for obtaining s-off. After you get your one time, one use license, if you need help with it you can either talk to @jcase or if he's not available you can come back here and I'll help you out. If your phone is 64 bit don't bother even trying to s-off it's not going to work with Sunshine and don't bother @jcase about it working for 64 bit because it doesn't and won't.

If you're not in USA then it doesn't matter because you're phone is most likely 64 bit since only 32 bit is sold in USA. If you're sim unlocked already there might be a way to get GSM to work so try this... Open the phones dialing pad and enter code *#*#4636#*#* and then tap Phone Information and then scroll down to "Set preferred network type" and select LTE/GSM auto (PRL) and then see if you can get it to work. But you'll most likely need your service providers APN (Access Point Name) and you'll have to set it up in the phones Settings in Network.

no, my phone is a virgin mobile (from sprint) i have tried the 4636 menu but with no luck, the phone only allows me to change to some of the options like LTE only, LTE CDMA, LTE WCDMA, CDMA EVDO GSM WCDMA LTE AUTO, GSM WCDMA LTE AUTO, GSM WCDMA, CDMA + LTE EVDO AUTO, and others and with any it doesnt wrabs signal. any of the gsm ones should do the trick but none does it.
and when i try to auto connect to network show that my simcard dont allow connection to this network and i tried 2 working sims with the same result

I've tried to tell a lot of people that there's no way to get a CDMA Virgin Mobile brand phone to work on GSM Networks, it's impossible and no one bothers to listen to me so I don't tell people to not try anymore I just try to support what they want to do. It's never going to work but you can keep trying and if you find a way to get it to work post the solution here.

ok, but how are you so sure?
the htc one m7 and the m8 from sprint can be used on gsm being cdma phones in first place, in fact i do own a htc one m8 from sprint that i succesfully unlocked and use it right now with a gsm network in my country.
also i do remember that other cdma/gsm phones like the htc pro 2 was capable to work on either network.
maybe something is still missing and we havent done all to achieve succes. ill keep try before selling the desire like this

Because Virgin Mobile purposely made it that way so that it can never be used with any other carrier but them... I know this because I have gone out of the Country a lot because I'm in the Military and when I asked VM to unlock the SIM card they said they cannot unlock it because even if they did it's never going to work with another SIM/Carrier and believe me I tried and tried while I was in Afghanistan and I eventually just gave up and bought a small stupid flip phone to use while over there instead. But like I said, you can keep trying. I'm not trying to tell you not to try because you might find a way when I couldn't.

hello,
we had a discussion about it in other thread. people tried it, soffed 510, and tried all the way. i have sprint, virgin, boost 510 sim unlocked. i am using it with other cdma carrier with evdo working. i even tried it setting to gsm, but it doesnt works. i tried adding gsm bands via dfs tool too, but still it doesnt work. igsm bands are locked in radio or radio doesnt have support for it. We need a gsm 510 radio to work on it. if someone have a knowledge uptill radio level, who can patch radio of 510 then it may work..
but @MrMike2182 is right too.. lol , but we never know... like sprint htc m9... people thought its impossible to unlock, but now you can sim unlock it ..

im begginning to suspect that the lower level devices the issue is that the hardware is acutially different. flagship phones are not made with many different variants,so the simlock and profile are controlled via software and thus able to be "unlocked"
ive gotten a sprint one max to work on gsm,but tried alot of different things trying to get a virgin mobile desire 816 to work with zero success. the fact that folks to use these phones on other cdma networks does indicate they are no longer sim locked.
cheaper phones like this the best advice is to sell it off and just get a gsm version. there are plenty out there that will work without the hassle.

Trust me I've done everything under the sun to get this sucker to work on GSM and it won't do it... When Virgin Mobile refused to SIM unlock it saying it cannot be unlocked I got pissed and S-off'ed the phone and it works with other CDMA carriers but it just won't work with GSM but I was thinking it may have something to do with the radio but I don't want to mess around with that just yet because that'll brick it for sure if I get it wrong..

true. lower end devices, dont have capabilities. i used htc one max sprint on gsm , it works on cdma with nv and also on simcard. m7 also works that way, but to make it work with other cdma sim, we have patched radio for m7, it was realased on some chinese forum, later posted by someone on xda. Htc one m8 sprint, verizon works best. works on gsm, works on cdma sim, works on nv too with other providers, you dont even need to touch radio.. i even relocked and got latest ota. still it works best with all. truly world phone..
