Adsterra & Other Pop Networks for TS Calls — Worth It or Not?

[adwareinc]

Hi everyone,
I want to confirm something from experienced members. For TS call generation, are networks like Adsterra or other pop-traffic networks still effective today? Or do pop-ups mostly give low-quality calls now?

Is it better to stick to Google/Bing for TS calls only, or can pop networks also work in 2025 with the right setup?

Looking for honest feedback from people who have tested both.

Thanks in advance!
