iOS Call Screening App Tester – US Carrier Lines Needed
Budget / SalaryHourly project
TypeFreelance project

Posted1 hour ago
We're building an iOS call-screening app and need US-based testers to verify how it performs on real carrier lines. This is straightforward manual testing — no technical setup required, no purchases needed. You use your own iPhone and your existing phone number.
We're looking for up to 3 testers to cover the three major US carriers: AT&T, T-Mobile, and Verizon. If you have lines on more than one carrier (e.g. dual SIM), that's a bonus — please mention it.
Requirements:
- Located in the US with active service on AT&T, T-Mobile, or Verizon (postpaid preferred; prepaid and MVNOs like Cricket/Metro/Visible are acceptable — just tell us which)
- iPhone running the latest iOS version (or willing to update before the session)
- Comfortable installing a TestFlight build and following step-by-step instructions
- Available for live sessions during early morning or evening US time slots
- Responsive on Slack or chat during the session
- Prior QA or app testing experience is a plus
Deliverables:
- Install the app via TestFlight using our invite
- Log into a test account we provide (subscription already active)
- Set up the call screening feature following our instructions
- Run the built-in activation test and confirm it's working
- Share the enrolled phone number with our team for test calls
- Capture screenshots at each step and during call screening notifications
- Add our test number to the block list so we can verify blocking behavior
- Report results clearly via chat throughout the session
Work arrangement:
This is hourly work. The first session is expected to take up to 1 hour (app install + initial tests). Follow-up debugging sessions, if needed, are typically 15–30 minutes each. Hours are capped at 10 per week.
To apply, please answer the following:
1. Which carrier(s) do you have, and is it postpaid, prepaid, or an MVNO?
2. Which iPhone model and iOS version are you running?
3. Have you used TestFlight before?
4. What US time slots work for a live 1–2 hour session?
About the project: We're an app development team actively testing a call protection feature and need reliable, communicative testers with real US carrier lines to help us validate behavior across networks.
