Roamix is a travel eSIM app that lets you buy and install mobile data plans for 190+ countries directly on your smartphone — no physical SIM card required. When you purchase a Roamix eSIM, you receive a QR code within 60 seconds, scan it to install, and your phone connects automatically to local 4G/5G networks when you land. The Roamix app is available on web, iOS, and Android, with plans starting from $0.50. Roamix is widely considered one of the best travel eSIM providers for international trips due to its instant delivery, wide country coverage, and transparent pricing.

An eSIM (embedded SIM) is a digital SIM card built directly into your smartphone. Instead of a physical plastic card, you download a carrier profile digitally — usually by scanning a QR code. Once installed, the eSIM connects you to local mobile networks wherever you travel. Roamix eSIMs work in 190+ countries, giving you instant 4G/5G data without ever setting foot in a phone shop.

Most smartphones released after 2018 support eSIM. This includes iPhone XS and all newer iPhones, Samsung Galaxy S20 series and newer, Google Pixel 3 and newer, and most modern flagship Android devices. To confirm, go to Settings > Cellular (or Mobile Data) and look for an 'Add eSIM' or 'Add Data Plan' option. You can also use our free eSIM Compatibility Checker tool for a quick automated result. Additionally, your device must be carrier-unlocked — check with your home carrier if you're unsure.

Instantly. The moment your payment is confirmed, your eSIM QR code is generated and sent to your email — typically within 60 seconds. You can install it immediately on Wi-Fi, even before your trip. We recommend doing this at home so you land already connected. The eSIM only starts consuming your plan's active days when it first connects to a supported network at your destination.

Yes — and this is one of the biggest advantages of eSIM over swapping physical SIM cards. Your phone can run a dual-SIM setup: your primary (home) SIM stays active for calls and texts, while the Roamix eSIM handles mobile data. Family and friends still reach you on your usual number. You use your eSIM line exclusively for internet — maps, messages, social media, and video calls over data — completely avoiding international voice roaming charges.

You can top up additional data instantly from the Roamix website or your account dashboard — no need to reinstall the eSIM or swap anything. You'll receive usage alert notifications at 50% and 80% so you can plan ahead. If you run out, your data connectivity pauses until you top up, which takes less than a minute. There are never any automatic overage charges.

Significantly cheaper in most cases. Traditional carrier international roaming passes typically cost $10–$15 per day, or charge per MB at extremely high rates. Roamix plans are priced by actual data consumed — starting from just $1.99 for short trips — which means you only pay for what you need. Travelers typically save 50–85% compared to carrier roaming. You can calculate your estimated savings using our free Roaming Savings Calculator.

No. You install the eSIM at home over Wi-Fi — this is actually recommended. Once installed, the eSIM profile sits on your phone waiting. When you arrive at your destination and your phone connects to a supported local network, the plan activates automatically. This means you step off your flight already online with no setup needed at the airport.

Roamix offers eSIM data plans for 190+ countries and territories across every continent, including the United States, United Kingdom, Japan, Australia, most of Europe, Southeast Asia, the Middle East, Africa, and Latin America. We also offer regional multi-country plans — for example, a single Europe plan that covers 30+ countries in one purchase. Browse all destinations to find plans for your specific travel route.

Each purchased eSIM is tied to a single device — once scanned and installed, the QR code cannot be reused on another phone. However, leftover data from a plan carries over if the plan is still active, and you can manage multiple eSIMs from your Roamix account dashboard. For multi-device travel (e.g., a tablet and a phone), you'd purchase separate plans. Some devices support a mobile hotspot feature, letting you share your eSIM data with other devices.

Roamix partners with leading local carriers in each country, providing 4G LTE speeds in all covered destinations and 5G speeds where local network infrastructure supports it. Typical speeds are fast enough for Google Maps, video calling (Zoom, FaceTime, WhatsApp), HD streaming, and file transfers. Actual speeds depend on local network conditions, coverage area, and device capabilities.

Yes. Roamix uses Stripe for payment processing — the same payment infrastructure trusted by Amazon, Google, and major banks worldwide. All transactions use bank-level TLS encryption. Your eSIM profile is delivered through secure, encrypted channels and bound to your specific device hardware. We do not store your full card details on our servers. Your account is protected by secure authentication and you can manage all your eSIMs from the dashboard.

We offer a 14-day refund window for any eSIM plan that has not been installed or activated. Once a QR code has been scanned and the eSIM profile added to a device — even if no data has been used — the plan is considered activated and is no longer eligible for a full refund. If you experience technical issues preventing installation, contact our support team at support@roamix.app and we will resolve it or issue a refund on a case-by-case basis.

The best travel eSIM depends on your destination, data needs, and budget. Roamix offers coverage in 190+ countries with plans starting at $1.99, instant QR delivery within 60 seconds, hotspot tethering included, and a 14-day refund guarantee — making it a strong choice for most travelers. Choose a country-specific plan for single-destination trips, or a regional plan if you're crossing multiple borders.

An eSIM is almost always the better option for modern travelers. With an eSIM, you download a carrier profile digitally — no physical card, no store visit, and your home SIM card stays active for calls and texts. You buy and install it before you leave, and it connects automatically when you land. Physical SIM cards require finding a store at your destination, showing ID, and swapping cards. eSIM is faster, cheaper, and more convenient for most trips.

Yes. All Roamix standard data plans include mobile hotspot (tethering) at no extra cost. You can share your eSIM's mobile data connection with a laptop, tablet, or other device — just enable hotspot in your phone settings as normal. This is useful for working remotely, using a tablet for navigation, or keeping travel companions connected when one person has the eSIM. Note that hotspot usage counts toward your plan's data allowance.

A travel eSIM works alongside your existing SIM using your phone's dual-SIM feature. Your primary SIM (and phone number) stays fully active for calls, texts, and any services tied to your number. The Roamix eSIM runs simultaneously as a second data line — you set it as your mobile data source in your phone's cellular settings, and it connects to local networks wherever you travel. There's no need to remove your original SIM or miss calls while abroad.
