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 the use of virtual numbers and may not guide users. This sometimes results in a long waiting mode and still no OTP received by a user! :(
In many cases, if you try to receive OTP/code by phone call, it is terminated by such sites. This results a 'missed call' on your 2ndLine.
The 2ndLine does not have any restriction about receiving SMS message or call from a number or site/app.
