- Check your Nextiva agreement for a notice period before you cancel.
- Don't close the Nextiva account until every number has moved.

Then move it to Onyx Phone
- Start your free trial. You get a temporary local number right away, so you can make and take calls today.
- Forward your current number to the temporary one if you like (most landlines: dial *72 and the number), so customers reach you here during the move.
- In Onyx Phone, open Lines, then Begin a port, enter the details above, and attach the bill. Moving a number is free on every plan.
- Sign the letter of authorization we email you. Nothing starts until it's signed.
- The carriers confirm a date, usually 3 to 7 business days after you sign. On port day your number replaces the temporary one, and calls you place show it.
- The temporary number keeps ringing your line for 30 more days, so anyone you gave it to still gets through, then it's released.
Texting registration doesn't come with the number. US carriers approve each business that texts, so register in Onyx Phone when you start the move; approval usually takes one to two weeks, and calling works meanwhile.

Questions about moving from Nextiva
How long does it take to move a number from Nextiva?
Usually 3 to 7 business days after you sign the letter of authorization. Nextiva and Onyx Phone's carrier confirm the date, and you get an email at each step.
Will my phone stop working while the number moves?
No. Keep your Nextiva service until the move is done. You answer on a temporary Onyx Phone number in the meantime, and you can forward your current number to it so customers reach you either way.
Does moving my number cost anything?
Moving it to Onyx Phone is free on every plan.
Can I text from the number as soon as it moves?
Texting registration doesn't come with the number. US carriers approve each business that texts, so register in Onyx Phone when you start the move; approval usually takes one to two weeks, and calling works meanwhile.
What if Nextiva turns the move down?
Onyx Phone shows what the carrier said, and you can fix the details and send it again. The usual reasons: the account number, name, or address doesn't match what the carrier has. Copy them from a recent bill; the PIN expired or was replaced. Get a new one and send the request again.
