How Does Roamix Work?

Roamix gives you mobile data in 190+ countries without swapping SIM cards or paying roaming fees. Buy a plan online, receive a QR code instantly, install the eSIM before you leave, and you're online the moment your plane lands. The whole setup takes about five minutes.

Step 1 — Choose Your Plan

Head to roamix.app and search for your destination country or region. You'll see plans from different carriers with varying data allowances and validity periods. Pick what matches your trip — a weekend city break needs a different plan than a three-week backpacking route.

Regional plans cover multiple countries in one purchase, which is ideal if your trip spans borders. Single-country plans offer the best value when you're staying in one place.

Step 2 — Purchase Instantly

Check out with your preferred payment method. Once your payment processes, Roamix emails you a QR code and your eSIM details within seconds — no waiting, no shipping address, no SIM card in the mail.

Your purchase is also saved in your Roamix dashboard at roamix.app/account, so you can access the QR code anytime even if the email gets buried.

Step 3 — Install Before You Fly

Install your Roamix eSIM 1–2 days before departure while connected to a stable Wi-Fi network at home. The installation only takes a few minutes:

• iPhone: Settings → Cellular → Add eSIM → Use QR Code
• Android (Samsung): Settings → Connections → SIM Manager → Add SIM → scan QR
• Android (Pixel): Settings → Network & Internet → SIMs → tap + → Download a SIM

Once installed, label the plan "Roamix" or "Travel" so it's easy to identify in your SIM settings. Then set it as your preferred data SIM and keep your home SIM active for calls.

Installing at home on familiar Wi-Fi is much smoother than scrambling at the airport. Airport Wi-Fi can be slow, congested, or require login steps that interrupt the eSIM download.

Step 4 — Activate When You Land

When your plane touches down, turn off Airplane Mode. Your phone will scan for available networks and automatically connect through your Roamix eSIM. That's it — no codes to enter, no hotspot to find, no SIM to insert.

If your phone doesn't connect automatically within a minute or two, go to your SIM settings and manually select the Roamix eSIM as your active data SIM.

When Does My Data Plan Start?

Your Roamix plan's validity period starts when your eSIM first connects to a network at your destination — not when you install it, and not when you purchase it. This means you can buy and install your eSIM weeks in advance without wasting a single day of your plan.

For example: if you buy a 7-day plan today for a trip next month, all 7 days of data will still be waiting for you when you arrive.

What about layovers?

If your layover country is covered by your Roamix plan, your data timer will start when you connect there. If you have a long connection in a country not on your plan, the eSIM simply won't activate until you reach your destination.

Does Roamix require an app?

No app is needed to use your data. The eSIM works like any mobile network — your regular browsers, maps, and messaging apps all work over it. You can optionally use the Roamix website to check data usage, top up, or manage your eSIMs.
