Traveler FAQ

Answers to common questions about eSIM for European travel.

Getting Started

What is an eSIM?

An eSIM is a digital SIM card permanently embedded in your device. Instead of inserting a physical SIM card, you download a carrier profile by scanning a QR code. The process takes under five minutes and can be done before you travel, so you arrive at your destination with data already active.

Is eSIM better than buying a local SIM card?

For most travelers, yes. eSIM eliminates the need to find a phone shop in each country, removes the risk of losing a physical SIM, and allows you to have data active before you arrive. A regional European plan covers 30+ countries automatically. The main limitation is device compatibility — older phones don't support eSIM.

Does my phone need to be unlocked?

Yes. A carrier-locked phone will only accept eSIM profiles from the locking carrier. Contact your carrier to request an unlock — most do this free of charge, and the process is usually completed within a few hours.

Plans & Data

How much data do I need for a European trip?

For typical tourist use (maps, messaging, social media): 5–10GB for 2 weeks. For heavier use including video calls and streaming: 15–25GB. Remote workers should consider 30GB+ or unlimited plans. When in doubt, choose more data than you think you need.

Can I use my eSIM as a mobile hotspot?

Most eSIM plans support mobile hotspot/tethering. Some plans restrict hotspot usage or count it against a separate allowance. Check the plan's terms and conditions before purchasing if hotspot is important to your use case.

Can I keep my home number while using a travel eSIM?

Yes. Use Dual SIM: keep your home physical SIM for calls and texts, and use the travel eSIM for data. Configure in Settings → Cellular: set the travel eSIM as the data SIM and your home SIM as default for calls.

Troubleshooting

No signal after arriving in a new country

Toggle Airplane Mode on for 30 seconds, then off. This forces the device to search for available networks. If still no service, go to Settings → Cellular → Network Selection and manually select an available network.

eSIM profile disappeared after a software update

Check Settings → Cellular — the profile is likely still stored but deactivated. Re-enable it from the SIM management menu. If genuinely gone, contact your provider with your order number to request a new QR code.

Can I transfer my eSIM to a new phone?

eSIM profiles are bound to specific device hardware and cannot be directly transferred. Contact your provider to request a new QR code for your new device. Some providers allow this for free; others charge a small re-issuance fee.
