[Q] SIM error when using unlock code?!

I have an unlock code for my Mozart but it seems to not be accepted.
When I enter it all I get is a SIM error message and then it asks me to enter my PIN again.
I don't know if there is a limit on entering the unlock code on the phone and I don't want to try over and over. I'm wondering if the problem may be the SIM isn't being recognised because it is a microsim in an adaptor.
Is it worth me trying a full size SIM? I have gotten the same code from multiple sources and so I find it hard to believe the code is wrong?!
Any guidance would be appreciated. Thanks.

Sim Unlock ZTE Midnight Pro (Z828tl)

Hey Guys,
Just wondering if there is a way to Sim Unlock a ZTE Midnight Pro from Simple Mobile (T-Mobile?)
When I insert a different sim card No direct prompt to unlock the sim pops up. It just asks to use the unlock app, and of course the app says it can't unlock the phone.
Surely there's gotta be a way (code, bypass?) to unlock it?
Thanks for the help!
Hi, did you find out how to do it?

Rooting a "semi-unlocked" phone

Hi guys. I have a Huawei M2. It's dialer locked but not network locked (tried 2 diff SIMs).
Most people will slot in a SIM and it prompts the unlock code. Mine doesn't do that. I have the unlock code. But I don't know where to enter it :S

If you've forgotten your Google Account password then there are lots of ways to recover the account:

If you bought the phone from someone, the only solution is for them to give you *their* password so you can unlock the phone, and then change it 72 hours later.
If you came across the phone via other means, factory reset protection is doing exactly what it's designed to do. There are numerous sites claiming to bypass it if you do a quick Google Search.

It's SIM-locked. You can buy an unlock code to fix this. I've used The Unlocking Company in the past for a Mate 20 Pro, so I can confirm that it works.
The bootloader lock irrelevant. It might update to 10.0 or 10.1 automatically when powered up, or when a new operator's SIM card is installed. If that doesn't work, HiSuite will drag it to the latest version.
What a bout frp ?
