1. No signal

The first cause is due to signal problems. How 'great' the SIM card you have depends on how strong the signal or network it has. When the signal is down or even exhausted it will definitely cause problems for you. One of these problems is when you type in the MMI code, it will say that the code is invalid.

2. Incorrect network settings

Errors in network settings may also indicate that your MMI code is invalid. To solve this, please check your network settings. Adjust to the existing network in your area whether it supports 4G or not.

3. Network operator interference

For these three reasons, it can be said that there is nothing you can do. You just need to wait until your operator has finished fixing the problem.
