Project Title: Fix OTP Country Code Issue in Mobile App (Wrong Country Code Sent) Project Description: Hello, I need an experienced mobile app developer to fix an OTP issue in my application. Problem: When users select their country and request OTP verification, the app always sends the phone number with country code +91 (India) instead of the country code chosen by the user. Example: If user selects Iraq (+964), Kuwait (+965), or any other country, the app still sends OTP only with +91. What I Need: - Check and fix country code picker / phone input logic - Make sure selected country code is passed correctly to backend/API - Fix OTP sending process for all countries - Test with multiple countries - Ensure app works properly on Android / iPhone (if applicable) Please Apply If You Have Experience With: - OTP integrations (Twilio, Firebase, MSG91, WhatsApp API, etc.) - Flutter / React Native / Android / iOS - Backend API debugging - Phone number validation libraries Important: Please mention: 1. Your experience with OTP systems 2. Similar projects completed 3. Estimated time to fix 4. Cost I need this fixed urgently.
