How do I get a phone number?
Pick one when you sign up by entering an area code. During early access, more numbers are added on request: email support@mail.topaz.tel with the area code you’d like. Each phone number costs $4.99 a month, taken from your credit every 30 days. Eligible new accounts (card saved at signup) get their first number’s first month free. If your credit can’t cover a number’s fee, we keep it for 7 days, then release it.
