GOOD TO KNOW / eSIM BASICS

What is an eSIM
for travel?

Mobile data for your trip, without looking for a new SIM card. Here’s how eSIMs work, who can use them and what to check before you go.

THE SHORT VERSION

An eSIM is a digital SIM that doesn’t need a removable plastic card. A carrier profile is downloaded to a compatible phone, allowing it to connect to a mobile network under your chosen plan.

The same mobile connection. A different way to set it up.

eSIM is a connection technology; a travel eSIM is one way to use it. You choose a package for a country or region and add it to your phone. It doesn’t turn a regular phone into a satellite device: you still need an available mobile network covered by your plan.

Remote profile downloads are based on the GSMA eSIM standard.

The travel eSIMs in the Ease catalogue provide mobile data. These packages don’t include a phone number, ordinary calls or SMS. You can use maps, email and messaging apps over data; the availability of individual apps also depends on your destination.

From choosing a plan to getting connected

  1. Choose a destination and plan

    Compare covered countries, data allowance, validity and available networks. For a trip with several stops, check that every country is included in a regional package.

  2. Add the profile to your phone

    Once your eSIM is issued, its QR code and manual installation details appear in My eSIMs. Connect to reliable Wi-Fi and follow the instructions for your device.

  3. Select it for mobile data

    At your destination, enable the travel eSIM and its data roaming as instructed by your plan. Check that your phone is using this line for mobile data.

You choose and manage an Ease eSIM in the Telegram Mini App, but install its profile in your phone’s settings. Once connected, your mobile data works without keeping the Ease window open.

For iPhone, follow our installation and data settings guide.

eSIM, a local SIM or roaming?

There is no single cheapest option for every trip. Compare the total cost, included data and convenience for your itinerary.

Digital profile

Travel eSIM

Choose a package online. You need a compatible phone. Coverage and conditions can be checked in advance; the start of validity depends on the plan.

Physical card

Local SIM

You need to obtain a card and have an available SIM slot. A local carrier may require registration. A phone number and calls depend on the package.

Your main line

Roaming

You keep using your current carrier. Check whether your destination is included, what data costs and what happens when you reach the allowance.

Data roaming on your travel eSIM and paid roaming on your home SIM are separate settings. Enabling roaming for the travel profile does not mean your home line should provide your mobile data. See Apple’s advice for international travel on using these lines together.

What to check before choosing

For the Settings checks, see our phone compatibility guide.

  • Your exact phone model and market. A product family name alone isn’t enough: eSIM support can vary. Your device must also accept other carriers’ SIMs. Check the manufacturer’s information for Apple or Google Pixel.
  • Every country on your itinerary. A destination name is not a substitute for the coverage list. A regional plan can appear under several destinations because it covers more than one country.
  • Data allowance and speed limits. A fixed package for the whole trip is different from a daily high-speed allowance. A daily plan may reduce your speed once its allowance is used up.
  • Validity and its starting point. Check whether the plan starts on installation or first connection, and the deadline for activating the profile.
  • Networks and extra features. Several carriers listed on a plan are available networks for the same package, not a separate allowance per network. Check the plan’s conditions for hotspot use and top-ups.

Network names and price don’t guarantee the same speed everywhere. Coverage, network load, your device and local restrictions can all affect the connection.

Installation and plan activation can happen at different times

Installation adds the profile to your phone. The plan’s starting event begins its validity period under the package’s conditions: for example, installation or the first connection to a supported network.

Don’t assume every eSIM should be installed well before your trip. First check what starts its validity. If the clock starts on installation, setting it up too early may use some of your days before you leave.

The activation deadline is a separate condition: you must start using the profile as required before this date. It is not the same as the plan’s validity after it starts. For example, a seven-day plan that begins on first connection counts from that connection; check its details for any additional limits.

In Ease, My eSIMs contains installation details, activation information, validity and available data usage figures. Usage can update with a delay. If something goes wrong, don’t delete the profile unless support asks you to: reinstalling it may not be possible.

A little more clarity

Can I keep my main SIM?

Yes, if your device supports the required SIM combination. Choose the travel eSIM for data and check your main line’s settings: calls, texts and accidental data switching may still incur charges from your home carrier. Dual SIM capabilities depend on your device.

Do I need internet to install an eSIM?

Prepare a reliable connection, usually Wi-Fi, to download the profile. After installation, mobile data needs a network included in the plan’s coverage; you don’t need to stay connected to Wi-Fi.

Do eSIMs only work abroad?

eSIM technology itself is not limited to travel. A particular travel profile, however, works in the countries and networks included in its package. Check that list even if installation was successful.

Where can I get help connecting?

Read the Ease setup instructions or contact support. Include your phone model, destination and order number. Don’t post your QR code or activation code in public chats.

Where to next?
