What is eSIM?

esim activated

eSIM is a built-in "digital SIM card" in your phone. You purchase a plan online, receive a QR code via email, and add the connection in the settings in 2-3 minutes. No plastic cards, no stores, no waiting.

Why Travelers Need eSIM

  • Cheaper than roaming. Often significantly more cost-effective than your home operator's rates abroad.

  • Internet upon arrival. If you set up eSIM in advance, you’ll be online at the airport.

  • Two numbers simultaneously. Your home number remains active while data is routed through the travel eSIM.

  • Cannot be lost or broken. It’s a profile on your phone.

  • Online purchase. No need to find a kiosk in an unfamiliar city.

  • Flexibility. You can choose a plan "for a week/10 GB/by regions" tailored to your trip.

Looking for "eSIM instead of roaming"? For travel, this is the simplest way to get cheap internet abroad.

How to Activate eSIM: 3 Steps

  1. Buy a plan online. Choose a country/region (e.g., "Europe" or "Asia") and the amount of gigabytes. A QR code and/or activation code (LPA) will be sent to your email.

  2. Install the profile.

  3. iPhone: "Settings → Cellular → Add eSIM → Scan QR".

  4. Android: "Settings → Connections/Network → SIM cards → Add eSIM → Scan QR".

    The connection takes a couple of minutes. Wi-Fi is required.
    3. Activate upon arrival. Open SIM settings, select eSIM as the mobile data source, and enable "Data Roaming" for this eSIM. Keep your home SIM for calls/messaging.

Compatibility: Will My Phone Work?

  • Supported by most modern smartphones (iPhone, Samsung, Google Pixel, many Xiaomi, etc.).

  • Quick check: try to find the option "Add eSIM" in the settings. If it’s there, you’re good to go.

  • Important: the phone must be unlocked (no SIM-lock). If purchased from an operator "in installments," check with them.

How Much Does It Cost

Prices depend on the country/region and data volume, but tourist eSIM is almost always cheaper than home roaming. You pay a fixed amount for the required gigabytes - no surprises on the bill.

How to Choose a Good Plan

  • Country/region. Do you need one country (e.g., Turkey) or an international eSIM for several countries (e.g., "Europe")?

  • Volume and duration. 3-5 GB is enough for maps, messaging, and taxis. For video/navigation with traffic - opt for more.

  • Speed and 5G. If video calls and navigation are important - check for 4G/5G support.

  • Activation. Some plans activate upon installation, others upon first connection in the country.

  • Top-up. Convenient if you can purchase additional gigabytes without changing the profile.

  • Support and refund. Availability of instructions, quick support, and refund for unactivated eSIM is a big plus.

At esim.bar, you can buy eSIM online with instant delivery to your email, clear instructions, and a fair refund policy if you haven't activated the profile.

Security and Expense Control

  • eSIM is hard to "steal" - it’s stored in the phone's memory.

  • You can delete the profile with one tap.

  • Manage expenses: turn off background updates, enable "data saver" mode, control streaming in high quality.
