Hi!

If I am not mistaken the router I bought has branded firmware that keeps me away from accessing the Internet from other service providers. I tried to call the the ISP (Orange as far as I know) told me that it is not possible that the device in any way is blocked/simlocked (they suggested contacting TP-Link), although I cannot explain why two other ISPs' SIM cards are not able to connect to the Internet regardless of the all network settings (APN, etc.). One card is properly identified, provides signal, even gives the auto config for the Internet but never connects - I can even send the USSD codes without problem. The second carrier unfroutunately shows that the SIM card is inserted but no signal nor Internet provided.

Is there any way, based on the provided Firmware Version, that someone could assist me with either upgrading/downgrading to see if it works? It's last resort cause I tried to set up proper APN for hours and none of these actualy works.

Any other option is also welcomed.

Cheers! :)
