  • free use phone numbers
    Https://freephonenum.com/ is one example, googling "single use phone numbers" (no quotes) yield others, but be careful: lots of "verify your phone number" sites are now disallowing these numbers for verification. Source: almost 4 years ago
  • Unlimited SMS code verification?
    Sites like https://freephonenum.com/ will give you a free number, but some websites now block numbers like that, including google voice numbers. Not sure if anyone's blocking numbers from paid providers such as twilio. Source: almost 4 years ago
  • Do you need a new phone number every time you create a new twitter account?
    I think I’ve used https://freephonenum.com but I don’t remember, you can try it out if you don’t mind the risk. Or you could get another phone, maybe a prepaid one for a month or something like that. Source: about 4 years ago
