Introducing Roamix Omni: One Global Pay-As-You-Go eSIM

Every travel eSIM asks you the same question before you leave: how much data will you need? Pick too little and you're buying a top-up in the arrivals hall. Pick too much and the leftover vanishes when the plan expires. Then you do it all again for the next country.

We built Roamix Omni so you never have to answer that question again.

One eSIM, Every Border

Omni is a single eSIM that works in 190+ countries. You install it once and it stays on your phone. Instead of buying a plan, you load a balance, and you pay only for the data you actually use, at the local rate of whatever country you're in.

Fly from London to Lisbon to Istanbul and Omni just keeps going on the same balance. No new plan, no new QR code, no hunting for Wi-Fi to install something at the gate.

What It Costs

There's no monthly fee, no daily fee and no plan to buy. You load $10 or more, and data is deducted by the megabyte.

Rates as of November 2026. Every network in every country is listed on the Omni page.

Your Balance Never Expires

Whatever you don't use stays in your balance for the next trip, next month or next year. There's nothing to finish before a deadline and nothing thrown away. If your balance reaches zero, data simply pauses, so you're never charged more than you loaded.

Features We're Proud Of

Auto Top-Up

Choose a low-balance point and a reload amount, for example below $5 add $25. When your balance drops that low, we charge your saved card and top it up, even mid-trip. It's off until you turn it on. If a charge ever fails, Auto Top-Up switches off and we email you, so it never retries your card in a loop.

Every network rate, published

Each country has a PREF (preferred) network, normally the cheaper one, and sometimes EXT (extended) networks that add coverage at their own rates. We publish every one of them, with its top speed, so you know exactly what you'll pay before you land. Your phone uses PREF first, and you can lock to it in your phone settings if you like. Here's the full explanation of PREF vs EXT networks.

5G in 118 countries

Omni connects at 5G wherever the network supports it, and 4G LTE everywhere else. Each network's top speed is shown next to its name.

Data on flights and at sea

Omni also connects on selected flights with airlines including Emirates, Lufthansa, Singapore Airlines, Turkish Airlines and Cathay Pacific, and on board ships from Cunard, P&O Cruises, Viking, Costa, Stena Line and more. Onboard data is satellite data and costs more than data on land, so it's best for messages rather than streaming. Here's how to use it without surprises.

Usage you can actually read

Your Omni dashboard shows your balance, your usage day by day, and a breakdown by network so you can see where every cent went. There's also a map that fills in with every country you've used Omni in.

Rewards on every top-up

Roamix Rewards members get an Omni bonus on card top-ups: 3% extra balance at Silver, rising to 15% at Elite. Invite a friend, and if their first purchase is an Omni top-up of $10 or more, they get $3 of bonus balance and you get $3 of Roamix credit. Roamix Wallet credit can also be moved into your Omni balance.

Omni or a Data Plan?

We still sell regular eSIM data plans for every destination, and for some trips they're the better deal. If you'll use a lot of data in one country, especially a higher-rate one like Japan, a fixed plan usually costs less. For short trips, multi-country trips, light use and frequent travel, Omni usually wins. We worked through five real trips in pay-as-you-go vs data plans vs roaming.

You can buy both in the same checkout, and many travelers do: a plan for the main destination, Omni for everything around it.

How to Get Started

1. Check your phone supports eSIM.
2. Load $10 or more on the Roamix Omni page.
3. Scan the QR code to install Omni, ideally at home on Wi-Fi.
4. When you land, set Omni as your mobile data line and turn on data roaming for it.

Your regular SIM stays on your phone for calls and texts. Omni handles the data.

Unused balance can be refunded within 14 days of purchase as long as the eSIM hasn't been installed. Questions? Our support team is here around the clock.

One eSIM, every border. We can't wait to see where you take it.
