I’m surprised no one has mentioned the issues with using Plivo to receive SMS. Maybe it’s due to recent changes from after the author wrote this article, but basically it won’t work for SMS verification in many cases.
I set up a Plivo number and got the email forwarding working, but when I tried to add the number to my Paypal account it wouldn’t work.
I asked Plivo support and got this reply:
“We would like to inform you that receiving verification codes on virtual numbers from various websites like Google, Instagram, Twitter etc., are not guaranteed as they get blocked by the providers. We would recommend you to use a valid mobile sim card number for receiving verification codes.”
So, basically, it’s useless for SMS two-factor authentication, which is my main issue. Any other solutions out there?
