I use SXT 4G Kit. I tring to get info by my balance. My 4g operator can send it via ussd request.
I try send the ussd by yours instruction (https://wiki.mikrotik.com/wiki/Manual:T ... D_messages), but I got error:
How can I send ussd request?/interface lte at-chat lte1 input="AT+CUSD=1,\"*105#\",15"
output: +CME ERROR: operation not supported
Or maybe the R11e-4G have any documentation about AT commands?
Or are there plans for utilities similar to SMS sending?
