Hello, I am very new so I'm a little nervous about posting but can somebody please help me?
I have a Sprint HTC One M8 and I have the unlock code from Sprint, however when I put in my sim card the phone reads "Invalid Card". I think this is because I would like to use the phone with T-mobile, a domestic carrier in the US. If somebody knows how to unlock the phone for domestic carriers and can help me or give me instructions I would be very grateful. I'd even be willing to pay if someone could take the time to figure this out. I have tried the unlock tutorials on the forum, but nothing has worked for domestic.

Good luck with your research. Domestic SIM unlock has not been successfully done on M8 as far as I know. There were some people did the domestic SIM unlock on M7 back in 2013 and you may want to leverage their work in your try (search in M7 forums). Sprint classified the M8 as international unlock capable and domestic – non capable in their website. M9 and up series have the capacity to get factory GSM unlock to use domestically. Please share your work if you get success.

Thank you for your reply sir. Which steps exactly are you referring to?
Because a friend got two sprint m8 relocked after he upgraded them to marshmallow. Is sim unlock confirmed for marshmallow? I see no posts to affirm this sir.

Hello,
I am currently living in Europe and i have a Sprint M8. Unfortunately s-off is not compatible with my phone (u might know about the whelp message).
I dont know even if this is possible, but if any of u guys has a contract with SPRINT, can you request an international SIM Unlock (GSM) for me (i dont need unlock for USA carriers, just for other international carriers)?
I can pay if the fee is acceptable.
Thanx!
first why would you get the Sprint version if you live abroad?
second sprint can unlock it so long as its payed off (not on someones contract) and hasnt been reported lost or stolen. just call sprint
Sent from my 831C using XDA Free mobile app
I cant call sprint from where I live. If somebody can do it for me im willing to pay.
I contacted Sprint from their Live Chat, and they told me i have to have an active contract with them in order to unlock. Which i dont have
Can anybody help?

if you want to try something on your responsibility then you can follow the sim unlock method without s-off (remember to make nand backup) & try if you get your device unlocked, if not then you will need to enable gsm band with QPST, with modified HTCOMADM_SPCS.apk.
I followed all that sim unlock method but my device still locked & i can't select gsm networks then i enabled it with QPST & all things worked ok.
the difference between us is s-off only.
I already tried it and the .apk files on /system/apps are replaced after i make the reboot. I guess this is why s-off is needed... I think i have to wait for the new s-off. Or till somebody with a Sprint contract will help me (if it is even possible since im in europe right now)

Try the following on you responsibility
- You should know your SPC, you can read it with CDMA Workshop or CDMA DFS Tool.
- Install QSPT (http://forum.xda-developers.com/showthread.php?t=2263391)
- enable diag mode ##3424#
- open QPST configuration, from port tab add your device diagnostics port.
- from start clients tab choose service programming then ok & click on read from phone.
- on system tab choose automatic for roam preferences.
- on UMTS System tab choose any for pref service domain & any band (last bottom right) for proffered band.
- click write to phone, then your device should work on GSM mode with modified HTCOMADM_SPCS.apk.
I'm with rooted, S-Off , bootloader unlocked HTC One M8 Sprint variant... I've even tried sim unlock... But it's still not accepting GSM sim cards... I think we need to have specific Prl update or UICC unlock for it to work

geeez... guess I can try one of those unlock sites..
I bought a used Sprint M8 Not HK version
And I successfully unlocked the simlock,because I have been to China and I can use the GSM and CDMA network there.
I want to change my carrier as AT&T or T-mobile even if Version Wireless,but it just tell me the SIM Card Is Invalid !
I visited a lot of website and tried any possible solution on the Internet,include but not limite in: Change ROM,Flash Radio,Format /cache /sytem /data,Retry simlock again and again,Set QPST,Set CDMAworkstation,Set DFS ...
Well,
I even want to buy the unlock code from xxxxxx.com,but they warn me do not buy the code if the phone didn't request.
Why the phone didn't request the unlock code?
I truly hope I can unlock this phone,
If you know how to deal with it,Please help me!
I am using Sprint (maybe)original ROM,Software version 3.31.654.2,OS vision Android 4.4.4,Baseband version 1.08.20.0916
Even if you SIM unlock the phone you can't use it on another domestic carrier. If you're international that's another story.

But it is designed can enter the unlock code to unlock domestic carrier and international carrier.
And the domestic unlock code is actually exist,just have no idea why this phone not ask.
Maybe the unlock program damage the part of domestic unlock function?
I try to unlock my Sprint M8,I tried T-mobile and AT&T sim card.
But my phone didn't likes youtube video, My phone didn't ask me about the unlock code. It just simply tell me the sim card is Invalid.
I have tried to use the unlock helper to unlock it, but it just unlock the internation lock.
I still want to unlock the domestic carrier lock.
Is it the ROM problem?
My phone use the Android 4.4.3,and it is S-OFF.
Please help me!
If you're trying to unlock your phone to use it on another domestic carrier, you're not going to be able to do that. SIM unlocking will work for international use.

Because your phone is carrier branded, you must sim-unlock it to be able to use it on another carrier.
You can sim-unlock using a paid code. There are many onlince service for that. A sim unlock code generaly cost between 5 - 15$ US. You put the sim card in the phone, boot the phone and then you'll be prompted to enter the code. (phone must be on stock rom)
This is an example of a website offering that service (not tested myself) http://www.doctorsim.com/us-en/unlock-phone/htc/
If your phone is s-off, you can sim-unlock for free if you have the required hardware and knowledge (SIEEMPI method)
There is also a new method to sim-unlock by using the Sunshine app (which was previously only useful to achieve s-off). The app cost 25$.
Version 3.1
Added HTC m9 support (not Verizon)
Added Experimental HTC Simunlock (Not m9, Not CDMA devices)

so try sunshine method, if it doesn't work, you'll have s-off anyway so it will be possible to unlock using the sieempi method
HTC 612 Verizon
is there a way to S-Off this HTC device for free like the old firewater I have no problem paying Sunshine app but I need this phone SIM unlock for a customer what if after paying for the app and gaining S-Off the SD Card method don't work for this phone
then I'm out of 25 dollars again no problem with that but I only need S-Off to SIM unlock the phone for a customer
Thanks

Your phone needs to be bootloader unlocked first. If it is, root was available from day one. If it is still locked, then no. AT&T can unlock your phone through tech support. You probably need to be paid off first though.
So I read that sum unlock will bootloader unlock also. How is this done? Through a sim card?
That's what I was just told.. let's see what happens here..

Once sim unlocked, the option to enable bootloader unlocking in developer settings will become available iirc.
No idea whats up with using a new sim card to sim unlock, if that's actually true or if that guy is full of it. The other thread mentioned its a server setting that needs to be done on ATT's side.

Only AT&T can SIM unlock your AT&T phone. Once your phone is paid off in full, wait 24 hours and then call AT&T tech support or go into an AT&T store. They will SIM unlock the phone, and then the "toggle OEM unlock" option will be available for you to unlock the bootloader.

I always thought it was done via pin input. I know the pixel 4 is different. When I was on chat with at&t I made it clear I wanted to use the dual SIM function in the phone and that it needed to be sim unlocked in order to do so. Supposedly this new sim that's bei g sent to me will sim unlock... IDK.we will see I guess
