Platform-by-Platform Recommendation
1. Telegram
Telegram supports almost all global carriers smoothly. * Budget Friendly: Indonesia, Brazil, and Kazakhstan deliver exceptional value. * Speed & Privacy: UK and Estonia numbers deliver SMS codes in under 5 seconds.
2. OpenAI / ChatGPT
OpenAI enforces aggressive bot detection. We strongly recommend United States (+1) or United Kingdom (+44) Non-VoIP numbers for guaranteed 99% OTP delivery.
3. Instagram & Facebook (Meta)
Meta systems demand clean operator lines. European lines (Germany +49, Netherlands +31, France +33) offer the smoothest experience.
