Hello @industeq,
USSD Codes are defined independently by each SIM provider/carrier network.
You will need to contact your SIM provider/carrier for more details on the USSD codes that they use.
Alternatively you could contact your local Peplink partner and they may be able to guide you on the local codes you are looking for.
Happy to Help,
Marcus
We are using the du network in the UAE. Dialling the USSD code requires us to reply by typing a number command, however, there is no way for us to reply to the instructions, as shown in the screenshot.
