Why is twitter saying my phone number is invalid?
Also know, why can't I add my phone number to twitter?
Tap Settings and privacy. Tap Account, then tap Phone number. If you haven't previously added a phone number, tap Add. Note: If you have already added a phone number, tapping this button will give you an option to Update phone or Delete phone.
Furthermore, why can't Airbnb verify my phone? To verify your phone number: Go to Profile on airbnb.com. We'll send you a 4-digit code via text message (SMS) or an automated phone call. Enter your code and click Verify.
Secondly, why is twitter asking for my phone number?
Twitter does not require new users to provide a phone number when they sign up — and so a user who was banned, and decided to create a new account, could do so even if they had harassed users previously. This move doesn't resolve Twitter's whack-a-mole troll problem entirely.
Can you have a twitter account without a phone number?
Yes, creating an account without a phone number is easy, described in other posts. It involves selecting email instead of phone.
