I'm looking to start a new campaign on an offer type I haven't seen that many discussions about: carrier billing.
In 2020, everybody uses apps for everything. But since there are still many networks with hundreds of offers in this category—mostly for tier 2 and 3 Geos—I'm wondering, is carrier billing still a thing? Do they make any sense to promote?
Also, would you recommend direct-linking? I know it's not a good practice anymore, and I'm all in for using pre-landers, but in this case, I'm not sure if adding a pre-lander to these offers makes any sense, or if it's possible. What do you think?
Thank you guys in advance!
It´s not dead but it´s by far not as big as it was few years ago.
In many good geos the regulations just got alot harder so that they times of easy flows with high payouts are over.
There are still good carrier billing offers out there, mostly in low tier geos, but often it´s no real 1 click flow anymore but rather a more complicated flow.
Thanks Twinaxe! Your guides are truly inspiring. I will check it now. As I said, I know carrier billing isn't as popular as it was and that direct-linking isn't optimal, I wasn't sure if it made sense. I guess I can only test and see it for myself now. 
In many cases it is the exact same as running sweeps SOI.
A lot of shit-tier geos don’t even have SOI, but have a bunch of pin submits.
Use a lander 
Thank you, sir! Will do.
