Hi. Thank you, for your quick response, but i do not have any suitable drop down Menu in the network Area.
The Button deafult SIM is on, Deny data Roaming is of, Service mode is Auto, Pin is clear because of deactivated on the Sim Card Itself, Band selection Auto.
Operator Settings only one button - enable is off
SMS Limit and USSD are off/clear.
Where do you want me to change the APN manually?
Edit after the Comment under this one: ( there is no Comment Button activated)
I Works. It seems to be my fault, and i am obviously not familiar enough with this Router and Setup.. but i will give it a try.
Thanks for your support. it Works an suspected.
