One app for messages, calls, your own number, and global data — encrypted, with instant translation, and built to keep working when the network barely does.
Watch it happen: a message leaves one phone and lands in the other, already translated. No switching, no copy and paste.
Most people juggle a messaging app, a calling app, a travel SIM, and a second number. CallUp folds all of it into one private home.
Private messages, photos, and voice notes. Free between everyone on CallUp.
Ring any phone in the world at a fair, transparent rate. Pay only for the minutes you use.
Your own number for calls and texts — tied to your account, not a SIM or carrier.
Global data that powers your phone in 200+ countries. No roaming bills, no surprises.
Voice and video calls between everyone on CallUp are free and encrypted — and they hold up even when the connection doesn't.
Privacy isn't a setting you switch on. It's the foundation CallUp is built on, all the way down.
Your messages and calls are encrypted on your device and stored encrypted. We hold your key so your chats follow you to a new phone.
No ads. Nothing sold. CallUp earns its keep only from the services you choose to buy — never your conversations.
Messages hold and deliver the moment a signal returns — tested across 2G, congested, and dropping connections.
Other apps stall, drop, or send your message three times when the connection wavers. CallUp was engineered for exactly those moments — the patchy tunnel, the crowded square, the village with one weak tower. Your words wait quietly, then arrive once, intact, the instant they can.
Call family across the world, top up data the moment you land, and carry one number that's always you — wherever life takes you. CallUp was made for people whose hearts live in more than one place.
CallUp works on your phone and your computer, perfectly in sync. Manage your team, your number, and every conversation from wherever you work — home, office, or on the move.
Free on your phone, or use it on the web. Your account is created in seconds, with no SIM.
Reserve your own global CallUp number, and the app opens in your language everywhere.
Message anyone on CallUp at no cost. Add calls, a number, or data whenever you want them.
Join CallUp and keep the connection that distance can't break.
