International calling on Allo lets you reach any country in the world. Each destination has a transparent per-minute rate, billed from a credit balance on your account. Some popular destinations are free.

​
Enable international calling on a number

International calling is off by default on every phone number. An admin or manager has to turn it on before anyone on the team can place an international call from that number.
1

Open the number's Settings

Go to the phone number you want to enable and open its Settings.
2

Toggle International calling on

Switch the toggle and save. Flip it off the same way when you need to disable it.
Once enabled, every member assigned to that number can place international calls.

​
Credits and rates: where to find them

Everything related to international credits and rates lives in one place: Settings → Billing, in the Credits section. From there you can:
  • See your current credit balance.
  • Buy credits manually, any time.
  • Set up or manage auto-recharge. A fixed top-up amount is added automatically when your balance hits zero.
  • Open the live rate list for the selected line. Click the “rates for the selected line” link to see the exact per-minute price for every destination, for that specific number.
Check your rates in Settings > Billing > Credits You can also browse every rate publicly at rates.withallo.com.

​
How calls are billed

Every international destination has a transparent per-minute rate. When you place a call, the rate for that destination is deducted from your credit balance in real time. Some popular destinations are marked as Free in the rate list. They do not consume credits. If your balance hits zero during a call, the call ends and you’re prompted to top up. If auto-recharge is on, a new top-up is triggered automatically.

​
Free destinations

A handful of destinations are free and do not consume credits when you call them. The exact list depends on your Allo number’s origin country. Free destinations are marked as Free in the rate list inside Billing and on rates.withallo.com.

​
What’s not supported

International SMS. SMS can only be sent to numbers in the same country as the sender.
Emergency numbers. International emergency numbers (112, 999, etc.) are not accessible through VoIP. Use your native dialer for emergencies.
A small set of high-risk destinations (satellite phones, known-fraud prefixes) is blocked for account safety.

​
Rates and destinations

The per-minute rate depends on the country of origin of your Allo number. Our carrier wholesale cost is different for a US number, a French mobile number, a French landline, a UK number, etc. The Credits section of Billing shows the exact rate list for each of your numbers.
In some cases, yes. If you frequently call a destination that is free from a French mobile number but paid from a US number, it may be worth placing those calls from your French line. The per-origin rate comparison is public on rates.withallo.com.
Yes, typically they go down. As Allo grows and we negotiate better deals with our carrier partners, rates drop and more destinations move to the free list. The Billing section and rates.withallo.com always reflect the latest pricing.
In theory yes, if a carrier raises our wholesale cost beyond what we can absorb. In practice this is rare. We notify customers ahead of any change that would impact pricing.

​
Team and admin

You can disable international calling entirely on a number from its Settings. More granular per-destination blocks are not available yet. If you need this, contact support.
Credits are account-wide. All international calls from any of your numbers draw from the same credit balance.

​
Other

Leaving a voicemail requires the full call to be placed and connected, so it’s billed at the same per-minute rate as a regular call.
No. The rate is per minute of connection, regardless of whether you’re on Wi-Fi or mobile data.
Both. International calling works from any Allo client (desktop, iOS, Android, web), and the per-minute rate is the same across all of them.
