Most registration sites now require you to submit your mobile phone number in order for them to send SMS verification. Most available online SMS/Phone number services (https://www.textnow.com/) can't be used and registration forms give our "This number can't be used" errors. I don't want to give our my actual mobile phone number because or robocalls. Are there online SMS/Phone number services with numbers that aren't blocked? I would be willing to pay monthly subscription, but free one-time services would be the best solution.
