Does this have something to do with programming?

So you got a response but it is just OK and no data.

Note that it might be necessary to enable reporting first using a AT+CUSD=1 command (which should respone with OK) before querying data using another command like AT+CUSD=1,"*111*2#". The option is usually disabled by default when powering up or sending a reset / default initialisation command.

Finally you should check if the "android samsung modem" and your SIM card supports the command. While the device should (otherwise there should be an error response), the SIM card might not (ask your provider).

As I wrote:
It depends on the device (mobile vs. modem) and the SIM card.

Did you use the same SIM card?
If not, try to use the SIM card from your mobile within the modem.
If yes, check the documentation of your modem.

Please don't shout. Using all uppercase is treated as shouting and being rude in the web.

Note also that I don't have access to the items used by you. I can't even see what you are doing or what is shown on your screen.

I just tried to help and gave you some hints. And we all do it here in our spare time without getting paid.

So sit down, relax, and try to find the source of the problem:

Is it the modem, the SIM card or both?

By using some combinations you should be able to find out.

If it is finally the modem, there is no solution besides using one that supports the required command.
