iPhone
Kalum is prepaid international calling that reaches any phone — and the person you call needs nothing on their end. No app to install, no account, no internet. You call over WiFi or mobile data, and their ordinary landline or mobile rings like any normal call.
That's what sets Kalum apart from app-to-app calling: internet calling apps only work if the other person has the same app installed and is online. Kalum places a real call over the worldwide telephone network, so you can reach anyone — including landlines, offices, and people who don't use messaging apps at all.
WHEN KALUM HELPS
• You're traveling without a local SIM or a roaming plan — call home from any WiFi
• Your mobile carrier charges too much for international calls
• You need to reach a landline, a business, or someone with no messaging app
• You want a dependable backup when internet calling apps are blocked or unstable
CALL 200+ COUNTRIES
Kalum connects to landlines and mobiles across more than 200 countries and territories — including India, Pakistan, Bangladesh, the Philippines, Nigeria, Kenya, Egypt, Mexico, Brazil, the United Kingdom, Germany and France. Open the app to see the exact per-minute rate for any destination before you dial.
HOW IT WORKS
1. Sign up with your phone number
2. Add calling credit — no subscription, buy only what you use
3. Dial any international number and talk
HONEST, PAY-AS-YOU-GO PRICING
• See the exact per-minute rate for every country before you call
• No connection fees, no monthly fees, no hidden charges
• No subscription and no contract
• Credit never expires and there's no minimum balance
• The credit you buy is yours to spend, dollar for dollar
WHY WIFI CALLING WITH KALUM IS DIFFERENT
Because only you need an internet connection, your carrier's international and roaming rates never enter the picture. Hotel WiFi abroad, airport WiFi between flights, café data, or your own couch at home — Kalum turns any connection into a phone line to almost anywhere in the world.
FEATURES
• Transparent per-minute rates shown before every call
• Prepaid calling credit that never expires
• Real-time balance on your home screen
• Calls to both landlines and mobiles — not just other app users
COVERAGE
Kalum reaches over 200 countries and territories. A few destinations subject to calling restrictions aren't available; if a country appears in the app's rate list, you can call it.
Wherever home is, Kalum helps you reach it — one clear, affordable call at a time.
A simpler start: pick the country you call, verify your number, add credit — with the price shown before you pay. Also fixes sign-outs after the app sat idle and a crash that could happen during a call.
