OTP Delivery Testing with Robi SIM

@vishal1145

Your OTP testing will fail if the APK doesn't handle dual SIM slot detection properly - I've seen apps default to SIM 1 and miss messages coming through SIM 2 entirely. Quick question - does your APK use Android's SubscriptionManager API to differentiate between the two Robi SIMs, or does it rely on broadcast receivers that might miss OTPs during doze mode? Also, are you logging which SIM slot receives each OTP, because carrier routing can be inconsistent across slots? Here's what I'll verify during setup: - DUAL SIM DETECTION: Confirm both Robi SIMs are registered using TelephonyManager and that the app isn't just reading the default data SIM. - PERMISSION HANDLING: Grant SMS, notification, and call log access while ensuring Android 10+ scoped storage restrictions don't block cloud uploads. - BACKGROUND PERSISTENCE: Test that the app survives battery optimization and doze mode - OTPs arriving at 3 AM won't get captured if the service gets killed. - CLOUD SYNC VALIDATION: Monitor logcat to confirm data packets are reaching your backend without SSL handshake failures on Bangladesh's network infrastructure. - OTP CAPTURE ACCURACY: Verify the app extracts OTP codes from SMS body text, push notifications, and in-app messages across WhatsApp/Telegram/Viber without missing edge cases like alphanumeric codes. I've tested similar telecom monitoring setups for 3 clients doing fraud detection and A2P SMS analysis. I'll document any anomalies like delayed delivery, wrong SIM routing, or permission denials that could skew your data. I'm in Dhaka with a Xiaomi Redmi Note 11 (Android 11), two active Robi prepaid SIMs, and can start today. Let's discuss the APK's architecture before I install it - I want to make sure we're capturing clean data from day one.
