Can't send SMS with Deco X50-5G anymore
Sunday
Model: Deco X50-5G  
Hardware Version: V2
Firmware Version: 1.1.1 Build 20250922

I'm using the Deco X50-5G with a SIM from O2 5G-plan "unlimited on-demand" with a data plan of 10 GB each day wich can be topped up in 2 GB steps by SMS, when the 10GB are used.

Until end of november 2025 sending SMS was working fine. Since then, sending SMS is generating an error message. When I put the SIM card into my mobile phone, sending SMS is working fine.

What can I do?

Hi,

If you still can reproduce this issue, could you please help me save the web UI system log and send it to support.forum@tp-link.com so that I can forward it to the senior engineer for further assistance.

(Please add forum ID#858356 in the subject.)

 

And can I also have a screenshot of the error message?

Wait for your reply.

Best regards.
