"SIM Lock" Network Locked - Enter unlock code

Even after doing the Hard SPL the device is asking for unlock code if I insert a foreigh sim card.
I tried doing the USPL also. Same results.
After Hard SPL I also tried to install Touch_IT_wm6.1_Full_-Herald_P4350.zip ROM. It installed well but show same SIM locked error.
Please let me know the steps to start fresh and unlock the phone for international usage. I also wanted to load custom rOM but as SIM not supporting so not able to proceed further.
Apreciate any help in this regard.
Device: T Mob Wing (HERA110)
HardSPL is a cid unlock which does not sim unlock the phone. Seeing as how you have a tmobile wing, you should call tmobile and ask them for the unlock code. Just tell them you're going out of country

in some case you can contact your carrier and give them your imei # and the will give you the sim unlovk code. You can also buy an unlock code from ebay or other internet sites. Did you asked the persons who Jtag repaired your device if they can provide you this code?

SIM UNLOCK PIN seems to be a security code from the sim card, try with another SIM Card from same carrier. Apparently it has nothing to do with unlock code.

So I had SIM unlocked at&t htc one (I obtained unlock code from carrier). Once I unlocked it, i was using european simcard and then revone s-off came out. so I s-offed it successfully and after reboot i got exactly same problem - enter sim imsi unlock code or something like that. Any code would result in unlock successful and reboot phone, but it would ask code again. I ended up sending phone to HTC for repairs. I guess they completely reflashed firware or updated something else, since phone that i received back had different IMEI then what i send them (same physical device though - scratches on the side). I had to obtain new unlock code for new IMEI and new code unlocked it for european sim.

SIM Unlock Reset by HTCDev Bootloader Unlock

Basically, I have an ATT branded M7 that should have been carrier unlocked. First thing I did was complete the HTCdev unlock to install TWRP and supersu. I completed a SIM swap from a mini-SIM to the micro-SIM for this phone and it is asking for the network password which the provider is telling means that it is not carrier unlocked? Could the HTCdev unlock caused this? Seems like the SIM unlock is in a different area of the boot loader that requires s-off so I think no. Need to contact the eBay seller but anyone have any other suggestions? Is S-off and unlock the only option for a permanent SIM unlock?

Bootloader unlock and s-off are not related to sim-unlock. You probably got scammed by the seller, but sim-lock can be removed easily using a sim-unlock code which you can buy online (for really cheap). So it might not worth wasting your time contacting the seller.
There is another method to sim-unlock that require s-off(sieempi)
Sim-unlock is permanent even if you unlocl/relock bootloader or if you turn security on/off (s-on/s-off)
Thanks for confirming. Is there anyway to determine if it has been hardlocked?

what are you talking about? Hardlocked?
Something about if an incorrect code 10 times there's another layer of locks (found AT&T page that references PUK and PUK2 codes). Are those different than the carrier lock we're discussing? Found a cheap code on eBay. Ordered it, will find out shortly I guess.

AFAIK (I'm not an expert on this) PUK codes are used to unlock the device when a wrong PIN was entered to many times in an attempt to access the device. PUK (Pin Unblock Key = Personal Identification number unblock Key) locks the device on a lower level or/and the sim card can become locked (preventing access to data stored on the card) but this have nothing to do with sim-lock that are locking your phone to a specific carrier.
Im not even sure if PUK is still used, ppl just reset their PIN using their google account or they are performing factory reset....
purchase the sim-unlock code, insert the new sim card, enter the code when prompted.
Thanks for the explanation. I did manage to test the new SIM in another phone and it worked and another known good SIM resulted in the same error (new info since OP). Maybe I should have paid more for 15 minute service... ?
Purchased unlock code did the trick.

How to put the sim unlock code?

I have the H/K edition. I bought an unlock code for it. My question is, how do you make the "enter the sim unlock code" appear?
Putting a different sim and turning on the phone doesn't work.

Galaxy S6 relocked itself to T-Mobile after 7 months ?

Hi everyone,
I've been using an SM-920T 64GB Galaxy S6 bought from T-Mobile last summer. I did a permanent unlock using the T-Mobile application and since July I've been using the phone on the AT&T network. I just rebooted my phone today like I always do and upon restarting I got an "Invalid SIM Card" and it brings up a SIM network unlock PIN window that I can dismiss or enter a code into. What is going on?
I'm running XtreStoLite Deo 2.4 if that makes any difference.
Also, does anyone have the T-Mobile Device Unlock apk that comes stock with the phone? This is how I unlocked the phone in the first place but I don't have that app anymore since I run a custom rom, and the play store won't let me download it because I don't have a t-mobile SIM card in the phone.
Thanks!
Well for the benefit of whoever has the same issue. I flashed back the stock ROM via ODIN, ran the T-Mobile Device Unlock app, it said Unlock Unsuccessful in big, but right below it said the phone has been unlocked permanently. I put in my AT&T SIM and it was working again. Then I flashed back my TWRP backup and the phone remained unlocked. The non-Tmo ROMs get the unlock popup when a foreign SIM card is inserted, so getting an unlock code should work, but I didn't want to wait 3 days to receive one.

Can you tell me what ROM you used? I have the g920T also, and bought it USED unlocked from ebay, but it had the FRP (factory reset protection) lock on it. I had my US cellular SIM card in it, even though I was stuck at the "enter your previous used google account on this device" and the SIM seemed to work (saw the LTE bars above).
But the only way for me to bypass the FRP was to flash to the ROM to stock (which I used the G920T tmobile ROM) and I got to the home screen but now it says "Invalid SIM card. Network locked SIM card inserted" just how you were saying.
When I try using the Tmobile unlock app, it says "Server not responding. Please try again later." .
Please help!
