Everything you need to
know about eSIM

An eSIM (embedded SIM) is a digital SIM card built into your phone. Instead of inserting a physical SIM, you scan a QR code and your phone connects to a local network — no waiting for shipping, no swapping cards.

Three ways. Physically: no card to swap, no SIM tool, nothing to lose. Contractually: a travel eSIM is a prepaid data product with a fixed duration — no contract, no notice period, no credit check. Functionally: it carries data only. Your phone number stays with your regular SIM, which keeps working alongside it for calls and texts.

AeroSims is a travel eSIM provider. We sell two things: unlimited plans for 175 countries, priced by trip length, and data packages from 3 GB to 50 GB for 195 countries, plus 32 regional and global packages. No roaming fees, no contract, no physical SIM.

Unlimited plans are available for 175 countries. Data packages cover 195 countries and territories, plus 32 regional and global packages — for example Europe, Asia, the Caribbean or a global package spanning 130+ countries. Browse the full destination list to find yours.

Да — данные не заканчиваются в течение всего срока действия тарифа. Чтобы местные сети оставались быстрыми и стабильными для всех, локальные операторы применяют правило честного использования: после необычно интенсивного расхода за один день скорость может быть снижена до конца этого дня и на следующий день восстанавливается полностью. Обычное использование в поездке — карты, мессенджеры, соцсети, музыка, видеозвонки и раздача интернета — этим не затрагивается. Если нужен гарантированный объём на полной скорости, наши пакеты данных дают фиксированное количество ГБ на полной скорости до исчерпания. В нашем обзоре по странам точно указано, что действует в каждой стране.

Take an unlimited plan if you stream, share a hotspot or simply never want to think about usage — it runs for the number of days you pick. Take a data package if you want a fixed amount of GB at full speed, or if you only need maps, chat and the essentials. Packages are usually the cheaper option for short trips.

No — AeroSims eSIMs are data-only. Your regular SIM stays active for calls and SMS on your own number, and you can make calls over the internet with WhatsApp, FaceTime, Signal or Telegram using your AeroSims data.

Most smartphones released after 2019 support eSIM, including all iPhone models from the XR onwards, Samsung Galaxy S20 and newer, and Google Pixel 3 and newer. Your phone also has to be carrier-unlocked. Check the full compatibility list to confirm your model, or dial *#06# and look for an EID number.

Yes — every iPhone from the iPhone XR and XS (2018) onwards supports eSIM. That includes the 11, 12, 13, 14, 15 and 16 series as well as the iPhone SE (2020 and 2022).

Yes — Samsung Galaxy S20 and newer, all Google Pixel 3 and newer models, OnePlus 12, the Motorola Razr series and many other Android phones from 2020 onwards support eSIM. See the compatible devices page for the full list.

Yes. The eSIM runs alongside your physical SIM, so you keep your own number for calls, texts and bank codes while AeroSims handles your data abroad. Nothing has to be removed from your phone.

Browse the plans, pick your destination and trip length, and check out. Your QR code is emailed to you automatically. Between 3 and 28 July 2026, 27 of our 28 orders were delivered automatically — median 14 seconds, slowest 18 seconds, all of them inside a minute. Measured from checkout to dispatch in our order system; figures as of 29 July 2026.

No. There is no ID check, no document upload and no SIM registration. You buy online, the QR code arrives by email, and you install it yourself.

Any time before you leave — delivery is automatic, so there is no lead time to plan for. Our practical advice: buy a day or two ahead, install it at home while you still have Wi-Fi, and let it activate on arrival. An AeroSims QR code stays installable for 180 days as long as you have not installed it, so buying well in advance costs you nothing.

In some countries, yes — but mostly in your favour. Several countries require identification to buy a local prepaid SIM; a roaming eSIM like ours generally avoids that, which is one of its biggest practical advantages. Beyond that, a few countries restrict certain services at the network level, for example internet calling in the United Arab Emirates, or filter parts of the internet, as China and Iran do. Those rules are set by the country and its operators, not by us — we cannot promise that any particular app or service will be reachable, and the situation can change. If a specific service matters for your trip, check its current status before you buy.

Install it before you leave, while you still have Wi-Fi at home. The validity period does not start when you buy — it starts the moment the eSIM first connects to a network in your destination, so installing days early costs you nothing.

About two minutes. Open your phone settings, scan the QR code from the email, follow the prompts, then set the eSIM as your data line and switch on data roaming.

You need some internet connection — Wi-Fi or your existing mobile data — to install the eSIM profile. Once installed, no Wi-Fi is needed: the eSIM connects to local networks on its own.

It depends on which product you bought. A data package has a fixed amount of GB — once it is used up, the connection stops and you buy another package. An unlimited plan does not run out for the duration you booked; the local carriers apply a fair-use policy, so after unusually heavy use in a single day the speed can be reduced for the rest of that day and returns to full speed the next day.

No — we do not offer top-ups. If you need more data, buy another plan for the same destination. It arrives by email and installs alongside the eSIM you already have, so you can switch between them instantly.

Yes. Buy a new plan at any time and switch to it on your phone. Several eSIMs can sit on the same device at once, so switching takes seconds.

Yes — order three eSIMs or more in one purchase and 10% comes off the whole order automatically. No code needed. For larger volumes, see our business page.

Each eSIM is installed on one device. To get a laptop, tablet or a travel companion online, use your phone's hotspot — tethering is included on every plan at no extra cost.

Your eSIM connects to our local partner networks in each country. Most destinations run on 4G/LTE; 5G is available in some countries and is stated on the individual product page. Actual speed depends on the local network, the time of day and where you are.

Write to support@aerosims.com with your order number. If we cannot get it working, you get your money back in full.

Yes. As long as the eSIM has not been installed on any device, you can request a full refund within 30 days of purchase, for any reason. If you are a consumer in the EU/EEA or the UK you also have the statutory 14-day right of withdrawal, which ends once you install or activate the eSIM. We review every refund request within 48 hours. Details are in our refund policy.

Email support@aerosims.com or use the contact page. We answer around the clock, seven days a week. Personal support is available in English, German and Bosnian/Croatian/Serbian.
