TOPSIM

Connectivity should be effortless. TOPSIM makes it that way — for your phone, and for everything else you need online.

For travelers and everyday data

Land in a new country and you’re connected before you reach baggage claim. No roaming charges, no airport kiosks, no swapping tiny plastic cards. Just instant data the moment you arrive.

And when you’re home, TOPSIM is the no-contract plan that doesn’t play games. No lock-in. No surprise overages. No bill that creeps up every quarter. Pay for what you need, change it anytime, cancel whenever.

For your connected devices

Trackers, routers, cameras, sensors, MiFi hotspots — if it needs a signal, TOPSIM keeps it online. Deploy one device or a thousand, manage every connection from a single dashboard, and keep them all running across 190+ countries. One account. One source of truth. Global coverage.

Everything you need, in one app:

• Activate an eSIM in minutes — scan, tap, done. 190+ countries. • Connect any device — phones, IoT, MiFi, and more, all in one place. • Watch data in real time — every line, every device, always clear. • Top up instantly — add data the second you need it, anywhere. • Switch plans on your terms — travel, home, or fleet. You decide. • Reach real support, 24/7 — actual humans, any time zone.

Whether you’re boarding a flight, cutting ties with an overpriced carrier, or keeping a fleet of devices online across continents, TOPSIM connects it all — on your terms.
