3G is not working anymore

RouterOS General
1

Hi I have several RB751U and RB951G devices with a UMTS stick.
Now they stop working.
Dialing out,
Modem hang up.

If I reconfig it with my settings (firste reset with no default configuration and than insert my settings) It will work ony once. If I power off the device and restart it, 3g is not working any more.

What can it be??

Hi!

At some point MT inverted the data and info channels - I think from 5.25 to 6.0

I had this problem and if I before hade “1” as DataChannel I now have to use “0” and the
same for Infochannel
