[Q] Vodafone G3 working on Orange

So, I just bought a new G3 from my carrier Vodafone Romania and wanted to unlock it so I can use it with other gsm carriers when I'm abroad.
Before buying a sim unlock code I wanted to make sure that it can be unlocked. So I popped in an Orange SIM and it worked without asking me for a code. Then I tried the other method by typing in the dialer 2945#*855# and got "the phone is permanently locked and cannot be unlocked".
How can this be? It's unlocked but permanently locked? Or this is the message you get after successfully unlocking?
Any insight will be appreciated.
I don't know if this matters but I'm rooted and twrp bumped on v20h

[Q] FREE UNLOCKING LG G2(Tmobile),possible or not?

Hi Guys
I'm from Europe and today I received an LG G2 (Tmobile) phone from a friend,but it seems that it is locked.I put my European SIM CARD and everything is ok when I start the phone,but I can't choose the MOBILE NETWORK option.I guess the phone is locked to TMOBILE USA. Is there a way to UNLOCK this phone for free and if not,which is the cheapest site where I can order UNLOCKING CODE for my LG G2? Is UNLOCKCODE247.com reliable website ?
Thank you

Can a network unlock code screw up your phone if done wrong?

My UK Vodafone 815 only fully works with certain sim cards. I used an unlock code from ebay and have zero issues with O2/GiffGaff sims.
Now I wanted to use a Life Mobile (EE) sim but the data speed won't go beyond E yet the same sim gets H+ in other phones. After the unlock iD Mobile/Three sims wouldn't make calls.
Can the network unlock have gone wrong somehow?
Still struggling with this....let me ask another question.
Is it possible to flash the original vodafone software (assuming I can find one) to re-lock the phone so I can start again with another unlock?

No service/SIM card not being registered

Hello.
I'm from Portugal and bought an HTC 10 wich is locked to T-Mobile.
Already got unlock code for it but i insert a portuguese network sim card and i never get the message to place the unlock code.
I checked the IMEI at T-Mobile website and it shows : Your device is blocked and will not work on T-Mobile’s network.
Already unlocked the bootloader and rooted the phone, thought that would be enough to overcome the T-Mobile app ( wich is to unlock the phone for the network ).
Any tips or comments on how i can solve this issue and use the phone with another sim card?
Thanks in advance
