5G, VoWiFi & Voicemail Scenario Testing
Manual system and UAT across iOS and Android
Manual network testing to support developers and senior testers: 5G latch and consumer-site checks, VoWiFi emergency and mid-call network swaps (VoWiFi / VoLTE / 5G), and difficult voicemail scenarios. Defect reports and test-exit reports on iOS and Android.
The Problem & Engineering Constraint
The Core Challenge
Carrier features fail at the seams — latching, emergency calling, and mid-call RAT swaps — and those paths are hard to automate fully on consumer devices.
Technical Architecture & Approach
Engineering Solution & Implementation
Followed a standard test process on iOS and Android: 5G latch and usage, VoWiFi UI and emergency numbers, swapping VoWiFi / VoLTE / 5G mid-call, plus voicemail edge cases. Wrote defect and test-exit reports.
Measured Production Impact
Verified Outcomes & Deliverables
Covered 5G, VoWiFi, and voicemail on both major mobile platforms.
Produced defect reports and test-exit reports for stakeholder communication.
