Before You Fly
How to set up an eSIM for Estonia.
Every provider on this list delivers an eSIM profile as a QR code. The setup process is the same regardless of which provider you choose. Install the profile at home over WiFi before your flight. The data plan does not start until you enable Data Roaming after landing.
iPhone Setup
- Settings > Cellular > Add eSIM
- Tap "Use QR Code" and scan
- Label the line (e.g., "Travel Data")
- Set as data-only line
- Enable Data Roaming for this line only
Android Setup
- Settings > Connections > SIM manager
- Tap "Add eSIM" and scan QR code
- Name the profile for easy identification
- Set as mobile data SIM
- Toggle Data Roaming on for the travel line
Keep your home SIM active for incoming calls and texts. The travel eSIM handles data only. Both lines run simultaneously using Dual SIM. When you return home, disable the travel line or delete the profile.

Troubleshooting
eSIM not working in Estonia? Fix it here.
Most eSIM activation problems are caused by three things: Data Roaming is off, the phone selected the wrong network, or the eSIM profile did not download completely. Here is how to fix each one.
eSIM installed but no data connection
Go to Settings > Cellular and confirm Data Roaming is enabled for the travel eSIM line. Not your home line. Toggle Airplane Mode on, wait 10 seconds, then off. The phone will re-register on the local network.
QR code will not scan
Increase screen brightness to maximum on the device displaying the QR code. Clean your phone's camera lens. If scanning still fails, copy the manual activation code from your email and enter it in Settings > Cellular > Add eSIM > Enter Details Manually.
Slow speeds after connecting
Go to Settings > Cellular > Network Selection. Switch from Automatic to Manual and select the primary carrier for your destination. Some eSIMs default to a secondary network with lower speeds. Switching manually often resolves this.
Phone says 'No Service' on travel line
Restart your phone. If the issue persists, remove the eSIM profile and reinstall it using the same QR code (some providers allow one re-scan). Contact the provider's support if the QR code is single-use and exhausted.
FAQ
eSIM setup for Estonia: common questions.
How do I set up an eSIM for Estonia?
Buy a plan from any provider, receive a QR code by email or in-app, then scan it in your phone's Settings under Cellular > Add eSIM. The profile installs in about 90 seconds. Enable Data Roaming when you land in Estonia. The entire process takes under 5 minutes over WiFi.
Can I install my eSIM for Estonia before I fly?
Yes, and you should. Install the eSIM profile at home over WiFi before your flight. The data plan does not start until you enable Data Roaming after arriving in Estonia. This way you connect instantly on landing without needing airport WiFi.
Which phones support eSIM for travel to Estonia?
Every iPhone from the XR (2018) onward, Samsung Galaxy S20 and newer, Google Pixel 3 and newer, and most 2022+ Android flagships. Your phone must be carrier-unlocked. Check Settings > General > About on iPhone or Settings > Connections > SIM manager on Samsung.
What if my eSIM does not activate in Estonia?
Toggle Airplane Mode on and off first. Then check that Data Roaming is enabled for the travel eSIM line specifically. If the network does not appear, go to Settings > Cellular > Network Selection and choose a carrier manually. Restarting the phone resolves most remaining issues.
Do I need WiFi to install an eSIM for Estonia?
Yes. You need an active internet connection to download the eSIM profile. Install over WiFi at home, at a hotel, or at the airport before departure. Once installed, the eSIM uses cellular data and does not need WiFi to function.
How long does eSIM activation take for Estonia?
From purchase to connected: under 5 minutes. The QR code scan and profile installation takes about 90 seconds. Selecting the correct cellular settings adds another minute. Most travelers are connected within 3 minutes of landing.
Can I use my home phone number with an eSIM in Estonia?
Yes. The travel eSIM adds a second data-only line. Your home SIM stays active for calls and texts on your original number. Both lines run at the same time using Dual SIM. Set the travel eSIM as the data line and keep your home SIM for voice.
How do I switch between my home SIM and travel eSIM in Estonia?
On iPhone: Settings > Cellular > select which line handles data. On Android: Settings > Connections > SIM manager > set the travel eSIM as mobile data. You do not need to remove your home SIM. Both lines stay active. Switch back to your home SIM data when you return.
