The APN is the "entry ticket" for the Internet. For the Internet dial-up of your data+ card, it is therefore necessary to configure the APN in the device.
To dial into the Internet via mobile network with your wherever SIM data+ card, it is necessary to set the APN correctly. The access data are as follows:
APN: wsim
Authentication method: none
Authentication user: blank
Authentication password: blank
Roaming: activate
We are aware that dial-up to the Internet works with some network operators even without a correctly set APN. Please note that we can only guarantee the best possible coverage and compatibility if the APN is set correctly. SMS and voice services also work without the APN being set.
