Who can make calls?
If you signed up for Firsty with a phone number, in-app calling is available worldwide: open the Phone tab in the Firsty app, add calling credit, and place outbound calls. When you call someone, they see that same phone number.
If you signed up with email only (no phone number on your account), the Phone tab and in-app calling are not available yet. You can still use Firsty for mobile data as usual.
How to make a call:
Go to the Phone tab in the Firsty app.
Add some credit.
Make your call — that’s it.
Don’t see the Phone tab?
If you signed up with email only, that’s expected for now—in-app calling is not offered on those accounts yet.
If you signed up with a phone number, update Firsty to the latest version from the App Store or Google Play. In-app calling ships with app updates, and older versions may not show Phone yet.
If you use a phone-number account, you’re on the latest app, and Phone still doesn’t appear, contact us and we can take a look.
Current limitations
Calling works in most places, but a few routes are still unreliable or not supported:
Calls within the United States (US number → US number): Some calls may fail depending on the other person’s mobile network or carrier. We’re still mapping where this happens, so we can’t give a definitive list yet. If a US-to-US call doesn’t go through, it may be a routing limitation rather than your phone—try again later or use another way to reach them if it’s urgent.
Calls within the Czech Republic: Domestic calls (Czech number to Czech number) are not supported.
Calls within Italy: Domestic calls (Italian number to Italian number) are not supported.
Calls within Singapore: Domestic calls (Singapore number to Singapore number) are not supported.
We’re working to improve coverage on these routes. Thanks for your patience.
