Hi, I understand you’re looking for Android users in Serbia with a Yettel SIM to help test RingApp by receiving automated test calls and keeping the app running in the background. I’m comfortable following the setup process (sign-up with Yettel number and enabling “Auto-perform tasks”) and completing the required 200-call sets reliably. I can ensure the app stays active and report back if there are any technical irregularities during testing. Looking forward for your positive response in the chatbox. Best Regards, Arbaz H
