USSD Code does not work

I’m in Malaysia
I own a MX4 Pro but since i bought this phone
online, i only managed to get a China version - “U” ROM (that is from Unicom).
Currently i tried to use USSD code ( *11# bla bla) in order to access to my telco menu. But sadly it cannot be done and it goes force close.

I want to try to flash “I” ROM version but from this forum i just knew that “I” ROM cannot be flash to the “A,U or C” version.

Does anybody also got this problem too? please help me to solve this problem

Download the latest(A) firmware and install it with clear data.

If you want to access the sim card uSIM menu you can try that with uSIM tool

The uSIM tool/app is only available on (U) Unicom firmware.

When you enter uSIM app
You’ll get the carrier specific options.

Here are my uSIM options

Hi, I am also from Malaysia with a MX4 Pro. My ROM version is “I” but I can’t seem to use USSD also

When you insert the sim card,the uSIM menu pops up automatically only if the sim card has programed uSIM menu.

If your sim card doesn’t have programed uSIM menu from the operator,
the USIM app will not appear because it is not present/programed inside the sim card chip.

Looks like your connection to Meizufans was lost, please wait while we try to reconnect.
