I used a TL 100. But now want to install a new TL MR 6400.

I use the Tether app to add the MR 6400.

i have a sim card from Odido ( T Mobie).

It is the sim card I used in the 100.

When I inatall the new 6400 it says everyrhing works. But the connection with internet does not work.

i tried a lot, but without luck.

i now took the sim out and use it in the 100. There it works good.

i need the 6400 to be able to connect more wires

I have no clue what I do wrong.
