Travelers love it

“Bought my plan while waiting for my bags in Denpasar. By the time I walked out of the airport, I was already calling my driver. 10/10 service.”

Essential for digital nomads

I've tried every eSIM provider and Roamix has the most stable connection. I worked from a cafe in Lisbon for a week using just their data. Highly recommend.

Game changer for travel

Super simple interface. I'm not tech-savvy but I had this set up in under 2 minutes. The 5G speeds in New York were incredible.

eSIM setup FAQs

Quick answers before you go.

Seconds. Your QR code is emailed as soon as your payment goes through, and it's saved in your Roamix account too. There's no manual review, so you can install it straight away.

No, and we recommend installing before you travel, at home on Wi-Fi. Most plans don't start counting days until you connect at your destination, so installing early costs you nothing.

Most phones from 2018 on support eSIM, including iPhone XS and newer, Samsung Galaxy S20 and newer, and Google Pixel 3 and newer. Your phone also needs to be carrier unlocked. Our free compatibility checker confirms both in seconds.

Yes. Your usual SIM stays in your phone, so calls, texts and WhatsApp keep your number. Most travelers keep their home line for calls and set Roamix as the line for mobile data.

Your data pauses, with no overage charges. We send alerts at 50% and 80% used, and you can top up in a tap from your Roamix account without reinstalling. You're back online within seconds.

Each eSIM installs on one phone, and its QR code can't be reused on another. For a second device, buy a second plan, or share your data with Personal Hotspot. You can manage every eSIM from one Roamix account.

Yes. Hotspot is included on standard Roamix plans. Turn on Personal Hotspot in your phone's settings to share data with a laptop or tablet. Hotspot use counts toward your plan's data.

Don't delete it unless you have to. Some eSIMs can be downloaded again from your Roamix account, but on others deleting is permanent. If you're switching phones, contact support before you remove it and we'll help you move.

Roamix works in 200+ countries on local partner networks, with 4G LTE everywhere and 5G where available. Your phone joins the best available partner network on its own, and each destination page lists its networks.

Yes, for many destinations. You can choose an unlimited plan or a fixed amount of data, such as 5, 10 or 20 GB, for the days you need. Bigger fixed plans cost less per GB, and you can top up anytime.

Everything happens before your trip and takes about 2 minutes. Buy a plan in your browser, get the QR code by email, and scan it at home. When you land, your phone connects. No store, no SIM card, no activation call.

Yes, with a regional plan. Our Europe plan covers more than 30 countries and our Asia plan more than 20. You install once, and your phone switches networks as you cross borders. Country plans are there for single-destination trips.
