A SMALL CHANGE. MORE FREEDOM.

What is eSIM? The essentials

An eSIM is a digital SIM. As a result, it lets you add a mobile plan to a compatible phone without inserting a physical card.

eSIM means “embedded SIM.” In other words, the technology is built into your phone. You download a digital profile, then choose the line you want to use in Settings.

Your eSIM connects your phone to a service. Meanwhile, your plan sets the included data, destinations and duration.

Before choosing a travel plan, check that your phone supports eSIM and is unlocked for the service you want.

A digital eSIM setup

Scan a QR code, use an installation link, or enter the details supplied with your plan. As a result, no physical card is needed.

An eSIM plan for your journey

Choose your country or region, then compare coverage, data and duration.

Your phone, connected

After installation and activation, select the travel line for mobile data. However, you’ll need a supported network and a local signal.

FROM YOUR PLAN TO YOUR PHONE

How does an eSIM work?

In short, your downloaded profile lets a mobile network recognize your plan. Once the line is active, your phone can connect to a supported network.

Getting started comes down to three simple steps.

1

Check your eSIM compatibility

First, check your exact phone model and regional version. Next, make sure it is unlocked, then review your destination’s coverage and included data.

2

Install your eSIM online

Next, connect to reliable Wi-Fi or another internet connection. Then follow the instructions supplied with your plan and keep your installation details private.

3

Select your eSIM data line

First, give the line a recognizable name and select it for mobile data. Also, follow its roaming instructions, and keep data roaming off on your home line.

Check when your plan starts. Installation and activation can be separate steps. For example, validity may start on installation, manual activation or connection to a supported network.

SAME PURPOSE. A DIFFERENT SETUP.

eSIM vs physical SIM: what changes?

Both connect your phone to mobile service. The main difference is how you install and manage them. However, speed and coverage depend on the plan and network.

MADE FOR THE WAY YOU TRAVEL

What is eSIM useful for abroad?

Arrange data before you leave

Compare plans before departure, so you’re ready to use maps, messages and transport apps when you arrive.

Keep your usual number available

On a compatible dual-SIM phone, your travel line can supply data while your usual line stays available. However, your home carrier may still charge for calls and texts.

Choose coverage around your itinerary

Choose a country plan for one stop or a regional plan for several. For this reason, check the included country list before buying.

Carry fewer small things

Instead, download your travel connection without carrying another SIM card. Also, keep your phone charged and your account details accessible.

LESS TO ARRANGE. MORE TO EXPLORE.

Travel connected.
Keep it simple.

Find Teliny country and regional plans for maps, messages and the moments you want to share.

  • Choose coverage for your destination
  • Set up digitally on a compatible phone
  • Find the data and duration that suit your trip

Check device compatibility, destination coverage and activation rules before choosing. Trial eligibility and plan terms apply.

Fixed data or unlimited data?

Fixed data: A set allowance, such as 3 GB, for your trip. For example, maps and messages usually use less data than streaming, video calls and cloud backups.

Unlimited data: Check the daily high-speed allowance, reduced speeds, hotspot limits and fair usage policy before choosing.

Match the plan to your trip

Likewise, match the validity period to your trip. Also, check when it starts, when unused data expires, and whether you can top up.

Compare the total price

Similarly, compare the total cost, coverage, data and duration. Finally, confirm your selected package and currency before checkout.

Understand your eSIM plan

In contrast, data-only plans provide internet access. You can use supported messaging and calling apps, but regular calls, SMS and a phone number may not be included.

A QUICK CHECK BEFORE YOU GO

Is your phone ready for eSIM?

  • Check your model. Use the manufacturer’s specifications to confirm support. An “Add eSIM” or “Download a SIM” setting can help you find the setup options.
  • Check your unlock status. Your phone must allow the service you want to use. Ask your home carrier if you’re unsure.
  • Keep your profile installed. Deleting it can prevent reinstallation. Ask support before deleting or moving an active plan.

GOOD TO KNOW BEFORE YOUR FIRST CONNECTION

What is eSIM? Your questions answered.

Clear answers to help you choose and use your next travel connection.

Does an eSIM need Wi-Fi?

First, you need internet access to download the profile. After activation, your plan uses a supported mobile network, so Wi-Fi is no longer required.

Can I keep WhatsApp and my contacts?

Adding a travel line does not automatically change your WhatsApp account or delete your phone’s contacts. Therefore, keep your existing messaging number unless you want to change it.

Can I use eSIM and my normal SIM together?

Yes, on supported dual-SIM phones. First, check your exact model, then choose which line handles mobile data, calls and messages.

Will eSIM make my internet faster?

Not by itself. Instead, speed depends on your plan, network, signal and phone. Also, check 4G or 5G availability and any speed limits.

Does eSIM include a phone number?

Some plans do. However, data-only travel plans may not include a number, calls or SMS. Therefore, check the package details before buying.

Can I share my connection with a laptop?

Yes, if your phone and plan allow hotspot sharing. However, your laptop uses the same data allowance, and extra limits may apply.

Can I install before arriving?

Often, yes. Check whether installation, activation or connection to a supported network starts your validity period.

What happens when my plan ends?

For example, service may stop when your data or validity ends. Next, check whether you can top up or buy another plan; renewal and profile reuse vary.

Can I move an eSIM to a new phone?

It depends on your device and plan. For this reason, contact support before deleting your profile or scanning its code again.

How do I get help with my Teliny plan?

Keep your eSIM installed and check coverage, validity and setup instructions. Visit the Teliny Help Centre if you need help. Also, keep activation codes and passwords private.
