Renting a number in Praxivara Phone usually takes just a few moments, but a purchase can stall for a few common reasons: your account needs payment details on file, your card asks you to confirm the charge, or you've reached the number limit included with your plan. This article walks through each one.

Before you buy: what's required

To rent a number, you'll need a payment method and a billing address saved to your account. The billing address lets Praxivara calculate any applicable tax and show you an accurate total before you confirm.

Numbers are billed as a recurring monthly fee. When you buy partway through a billing cycle, the first charge is prorated for the remaining days, and the number then renews with your regular billing.

"No card on file" or missing billing address

If you see a prompt that a payment method or billing address is needed, add them before completing the purchase.

  1. Open your billing settings from the account or Settings area.
  2. Add a valid card as your payment method.
  3. Enter your billing address so tax and totals can be calculated.
  4. Return to Praxivara Phone, search for a number again, and continue to checkout.

Once a card and address are saved, the purchase screen will show the number's price, any tax, and the total before you confirm.

Tip: Review the total on the confirmation step before you buy. This is where you'll see the prorated first charge for the current cycle alongside any tax.

3-D Secure card authentication

Some cards require an extra verification step from your bank, often called 3-D Secure. If your bank requests it, a secure authentication prompt appears during checkout.

  1. Complete the verification when prompted. This may be a one-time code sent by your bank, a push notification in your banking app, or an approval in your bank's own screen.
  2. Wait for the authentication window to finish and return you to Praxivara. Don't close it early.
  3. After your bank approves the charge, the number is provisioned and appears in your Praxivara Phone list.

If authentication fails or times out, no number is purchased. You can safely try again. If your bank keeps declining the step, contact your card issuer or try a different card, then repeat the purchase.

You've reached your plan's number limit

Each plan includes a set number of rentable phone numbers. If you've reached that limit, the option to buy another number is unavailable until you free up a slot or move to a plan that includes more.

Free up a slot

If you have a number you no longer need, you can release it from Praxivara Phone. Releasing a number stops its billing and frees a slot so you can buy a different one.

Note: Releasing a number can't be undone, and if an agent depends on that number to answer or place calls, those calls will stop. Reassign or reconfigure the agent first if you still need it.

Get more numbers

If you need to keep your current numbers and add more, higher plans include a larger number allowance. Upgrade your plan, then return to Praxivara Phone to buy the additional number.

Other things to check

  • Number no longer available. Availability changes quickly. If a specific number can't be purchased, search again by country, area code, or digits and pick another.
  • Card was declined. Confirm the card is active and has funds available, then retry. If it keeps failing, add a different payment method in your billing settings.
  • Purchase didn't complete. If checkout was interrupted, no charge is finalized and no number is reserved. Start the purchase again from Praxivara Phone.

After you buy

Once a number is yours, assign an agent to answer inbound calls and write its greeting, turn Accept inbound calls on, and choose which number is your default for outbound calls. This makes sure incoming calls are answered and outbound calls use the right line.
