I am currently using digits for a web-application. I have been testing the application using my personal phone number, which works great. However, after asking my friend to try the app, he could not log in and received the error "Invalid phone number".
This error is very ambiguous. I tested entering his phone number using 3 different devices and different browsers, and the error was the same. There is not much information that I could find about this error.
In addition to testing on my web-app, I asked him to try to sign into: digits.com/signin, where he was also unable to log in and received the exact same error, "Invalid phone number". (The problem is not my application).
This error is especially strange since we have phone numbers from the same area code.
My Verizon number : +1 210 789 xxxx
Works fine
His T-Mobile number: +1 210 723 xxxx
Returns error
Any information on this would be helpful.
Thanks!
