Getting a USSD interface to work in a mobile WiFi router - eviltoast

I have a mobile wireless router (PW100 4G LTE Router) that provides WiFi via a SIM card. I have purchased several data “bundle codes”. One way to activate a data code is to send a USSD code: *101*CODE#

The router’s interface provides a USSD Service interface through which I should be able to send these USSD codes.

When I attempt to load a bundle code, or to check my balance by submitting the USSD code *101#, the site hangs and eventually prints out: “session terminated by network”

If I place the sim card into a phone I am able to issue the USSD codes without problem. So, it is the wireless router that is not properly managing the USSD connection.

I have been trying to troubleshoot this with no success. Do any of you here have experience with WiFi routers, or with USSD codes in general, and might have some suggestions of things I can try?

    I see… I understand. Thank you!

    It is a bit unfortunate because my mobile carrier only allows me to top-up via USSD or via a phone call, not via SMS. So I won’t be able to top up without removing the sim card and placing it into a phone. It is a minor inconvenience, but an inconvenience nonetheless 😁
