Hello, trying to send code to enable option on the mobile sim without any luck, Every code I try, even the ones that work fine on a mobile using a SIM from the same provider are returning an error message "USSD session is terminated by the network." and I am not getting any response.
Is there any way to do this without removing the simcard?
That fancy sticky adapter also does not help to make it quickly and without tools in case you got a modern micro-sim and need to use it for fit.
