I am repeatedly receiving an annoying SMS message to my RUTX11 from exactly 1 specific number. I normally do need SMS→email forwarding enabled, but want to block this specific number from receiving/forwarding messages.
Is this somehow possible, using the GUI or otherwise?
The most reliable approach would be to contact your SIM provider and request that they block the unwanted number on their side. There is no built-in functionality in our devices to block specific senders. Even if you configure an SMS whitelist, it will only restrict which numbers are allowed to execute router commands. The SIM card will still receive SMS messages regardless of the sender.
I hope this clarifies the situation. If you have any further questions, feel free to let me know.
