Connection problem or Invalid MMI code

[xJoshx]

Ok so I've had a problem for awhile now about this error message and I've put my sim card into another phone and it doesn't show up on there,but when I put my sim card back into this phone (A22 5G) it just gives me that error code!

What is wrong-?

It might be the sim card with a fault

But it works in other phones??

You must've made a mistake explaining on your original post.

Have you tried other sim cards on your phone to see if they work?

And also take a screenshot after dialing that code, I want to see what it shows

Ok I'll send a screen shot and test and different SIM card give me a moment

[xJoshx]

There

All is well there, just try using a different sim and see if you'll still receive the same errors or not

Ok I must find a different SIM card ,I know I have one but I misplaced it so will get back to you when I have found it
