TL-MR6400 4g Router not woring with DIGI mobile (Spain) sim.
My neighbour has purchased a TL-MR6400 router to use with his Digi sim, however it doesn't seem to work, he never gets a data connection.
We've tried using other sim cards which work fine and his Digi sim works in my MR-600 fine, my own Digi sim won't work in his router either. We updated the firmware also to no avail. We've come to the conclusion that his router doesn't like the Digi sim cards.
Does anyone have any experience on this?
