Mobile Phone Numbers and Text Messages
Dear domain registrars, don’t assume phone numbers for your customers can accept texts. Some businesses have landlines. Provide other options for verification.
After having moved my phone number to plan where I can make and take international calls, but no SMS (at least not yet), it was excruciating to see how many problems this causes. E.g., platforms that will send you a one-time token to your phone number to change your phone number(sic!).
