Question about TP-Link Tl-Mr6400
My SIM is not recognised. I have tried 3 different ones, all of which work in the phone. Firmware is up to date, factory reset and reboots I have also tried several times. Is this a known problem?
Hi, I've had sim cards from different providers in it and they've all worked. Did you deactivate the pin of the SIM before inserting it into the router? Otherwise it won't work because the pin can't be unlocked in the router =) You can remove the PIN if you have the SIM in the mobile phone.
