People often ask this as:

  • The app does not receive OTP from Telegram, WhatsApp, Twitter, why so?

First, please be aware about Virtual Number through the article.

Such websites and apps like Telegram, WhatsApp, Twitter, etc. often do not allow use of virtual numbers and may not guide user. This sometimes results as a long waiting mode and still no OTP received by a user! :(

The 2ndLine does not have any restriction about receiving SMS message or call from a number or site/app.
