Today i run some new offer about app download, traffic is popad also, i use the A/B text, for example:
campaign 1
os: android
traffic type: carrier only — att
geo: u.s only.
device: samsung
campaign 2
os: android
traffic type: carrier only — tmobile
geo: u.s only.
device: samsung
i only change the carrier, so i need to build 4 campaign, is it right?
