Because I think it's not really well known I started the question just to answer it myself.
Right now it seems to be Bitel.
They're service is not yet spreaded like Movistar or Claro, but they're developing.
So they're the first we came across with a flat rate like we're used to from Germany. Bitel got different pre-payed plans.
1 day flat
1 month flat with different volumes
So, after finishing the volume they just limiting the speed, so you got still internet access.
Tethering works quite nice for us. Check out they're plans
And no, I'm not affiliated in any way. Just like to share knowledge.
