Can I call someone who has no internet at all?

Yes. Kalum routes your call through real phone networks, so the person you call needs no internet, no app, and no smartphone. An old landline or a basic feature phone rings like it would for any normal call.

Do I need internet to make the call?

Yes — on your end only. The Kalum app uses your data or Wi-Fi to start the call, then hands it over to regular phone networks. The person you call never needs a connection.

Can I call landlines?

Yes. Kalum calls landlines and mobiles in 200+ countries. Whoever you call answers on whatever phone they already have — nothing to download, nothing to set up on their side.

Rates are per-country, and the app shows the exact per-minute rate before you dial. You add prepaid credit starting from $4.99 — no subscription, and your credit never expires.

No internet needed on their side

Call people who don't have internet. Their phone just rings.

Kalum is an international calling app that reaches real phone numbers — landlines and mobiles in 200+ countries. The person you call needs no app, no smartphone, and no internet.

Start with $4.99. No subscription. Credit never expires.

You need internet. They don't.

Internet calling apps only work when both sides are online with the same app installed. Kalum works differently: the app uses your data or Wi-Fi to start the call, then routes it through regular phone networks to the number you dialed.

From the other person's side, nothing changes. Their phone rings like any other call — whether it's a landline on a kitchen wall or a feature phone from fifteen years ago. They pick up, and you talk.

You see the per-minute rate for their country before you dial, and calls are billed by the minute with a 60-second minimum. No connection fees, no hidden charges. See how Kalum works →

Made for the phones apps forgot.

Landline-only households

Parents and grandparents who never moved past the home phone. Their landline can't install an app — with Kalum it doesn't have to.

Feature phones

Plenty of the world still calls from phones with buttons. Any number on any carrier rings, no smartphone required.

Unreliable internet

Power cuts, weak coverage, expensive data. When the internet on their side is down, a regular phone call still gets through.
