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-?

Hi Josh1803, we apologize for the inconvenience.

 Turn off your phone (press the Power button for a few seconds) and reboot again, see if that helps in fixing the connection problem or invalid MMI code on your phone.

Alternatively reboot in safe mode or enter safe mode, follow these steps:

1. Turn off your device.

2. Press and hold the power button to turn on, continue holding the power button until the logo screen appears. Release the power button once you see the logo.

3. Press and hold the volume down button until the reboot is finished.

4. You should see “Safe mode” at the bottom left corner of your screen (left of the screen).

Can you dial *#0011# and scroll down until the imei status and check if it says "OK"

[xJoshx]

Only says IMEI certi**

Are you able to search for networks?

[xJoshx]

If u mean data networks then yes I can

I just meant networks in general and also having network reception, but since you can use data network it answers my question.
