When you sign up for Locket, you'll be asked to enter your phone number. We'll then send you a verification code to confirm your number.
If you see an error message after entering your phone number:
Double-check that the country code at the start of your number is correct.
For US numbers, it should start with +1.
For UK numbers, it should start with +44.
If the country code is incorrect, delete it and manually enter the correct one.
