Calling & Add-ons

Every phone line can make and receive calls. Two optional add-ons stop the “Potential spam” label some people see when you call. If you pick an add-on at checkout, it’s already paid for: each phone line you order after that gets it automatically, with no new charge.

​

What every phone line includes

• 500 outgoing minutes per line per month, with call recording. Minutes are shared across your phone lines.
• Unlimited incoming calls, free, forwarded to the number you choose. That number must be in the same country as the line’s eSIM.
• Extra minutes: 100 for $3.

A regular call can show “Potential spam” until the person saves your number or taps “Mark as known”. Text them first, then call. To learn why, see Limits: Calling.

​

The two add-ons

Add-ons are chosen per line. Registered caller ID shows your name on US-to-US calls to mobiles on T-Mobile and Verizon. Carriers check your business first, so it can take a few business days to go live. You give us your business details in a short form. See Registered caller ID setup.

​

Add-ons you pick at checkout

When you tick an add-on at checkout, you buy it for every phone line in your plan. It’s charged with your plan. After that, each phone line you order gets one automatically. You don’t tick anything again, and you aren’t charged again.

​

On the line order page after checkout

Right after you pay, you order your lines. If you picked add-ons at checkout, each line shows a green box:

Included with this line, already paid at checkout FaceTime Audio add-on: added to this line automatically. No new charge.

If you picked Registered caller ID, this page also shows the Caller ID details form. You can fill it in now or later. Your line is ordered either way.

​

When you add a line with Provision Line

On Lines → Provision Line, the Calling step shows each add-on you already paid for as ticked and locked, with a Paid at checkout badge and a note like this:

You already paid for FaceTime Audio at checkout (1 unused). It’s added to this line automatically. No new charge.

• The “Charge me for…” box only lists add-ons that will really be charged. If everything you picked was paid at checkout, there’s no charge box at all.
• On the review screen, a paid add-on shows “(already paid at checkout, no new charge)”.
• If you tick an add-on you didn’t pay for at checkout, it’s charged like any other add-on. See the next section.

​

Adding an add-on to a line you already have

1. Go to Lines and click Calling on the line.
2. Tick the add-on you want.
3. Tick the box to agree, then click Add.

What the box says depends on whether you already paid:

• Already paid at checkout. The card shows Paid at checkout and “You already paid for this at checkout (1 unused). Adding it to this line costs nothing today.” The box reads: “Add … to this line using a slot I already paid for at checkout. No new charge. It renews with my plan.”
• Not paid yet. The box reads “Charge me for … on this line”. We charge the card on file today: the setup fee plus a prorated share of the monthly price. Then it’s charged monthly. Non-refundable.

Tuco always uses an add-on you already paid for before it charges for a new one.
