2021-05-01 07:54:16
Model: TL-MR100
Hardware Version: V1
Firmware Version: 1.3.0 0.9.1 v0001.0 Build 210119 Rel.31129n

I use HO-MOBILE provider (Vodafone).

It was working before the upgrade, I saw there was an upgrade available and after that stopped working.

 

Current ISP version: 20082701

 

I also created a new profile but I think the problem is not here.

I don't see "Signal" informatio at all in the status page and this should be present despite the ISP configuration.

 

I suspect there is a problem gathering IMSI from the SIM -> problem the the last firmware -> need firmware fix

 

No possible a firmware downgrade, already tried.

Can we have a screenshot of the Internet Status page when you insert the SIM card into the router correctly? If the SIM card is not detected, please try to reset the MR100 to factory defaults by pressing and holding the reset button until the LEDs flash off then on, take out the SIM card and put it back in, then confirm if it can be detected.

 

Please also try to put the SIM card into a mobile phone to check whether the SIM card still works.
