IPFire WAN Modem Settings Help

I disabled NAT on my Router with SIM Card and want to setup the IPFire wan port with all that PPPOE and DialUp Options and so on. I have never configured something like that so I wanted to ask you guys to help me, because the Dialup Page is a bit confusing.
So how do I connect with my APN Credentials and so on?
