Greece Unlimited   / Santorini Caldera

The validity of eSIM plans varies from 7 days to 90 days depending on the plan you choose. Lifetime options are also available for travelers who don't want their data to expire after a fixed period.

Prices commence at $5.90 and vary according to data allowance and plan duration. Larger data plans and longer durations cost more, but the per-GB rate decreases with bigger packages.

eSIMno offers 24/7 support via WhatsApp and email. Our human support team - not bots - handles installation help, troubleshooting, billing questions, and refund inquiries. Most issues are resolved within minutes during business hours and within a few hours overnight.

You can purchase your eSIM directly from the eSIMno website - select a Greece-unlimited plan and complete the payment. Within minutes you'll receive an order confirmation email that contains everything you need to install: a QR code, a one-tap install link, the SM-DP+ address and activation code, plus an "Install eSIM" button. You can install straight from that email, or sign in anytime and go to Profile > My eSIMs > Install to get the same options.

Yes - eSIMs typically connect within seconds of switching off airplane mode at the gate. Major airports have strong cellular coverage from local partner networks, so you'll have data before reaching baggage claim. No setup needed at arrival.

Your eSIMno order confirmation email contains your QR code, your SM-DP+ address and activation code, a one-tap install link, and an "Install eSIM" button - so you can install right from the email. The same options are also on the website: sign in at esimno.com and go to Profile > My eSIMs > your plan > Install. To install, use any ONE of these methods: (1) on the phone you are setting up, tap the one-tap install link/button (iPhone on iOS 17.4+ or Android 9+); (2) use the QR code - because a phone cannot scan its own screen, show this QR on another screen (computer/tablet) or a printout and scan it WITH the phone you are setting up (never with someone else's phone, or the eSIM would install on that phone); or (3) enter the SM-DP+ address and activation code manually. Your Greece-unlimited eSIM activates automatically when you connect to a local network at your destination.

We recommend turning off cellular data and data roaming on your original SIM while abroad to avoid accidental roaming charges. You don't need to physically remove the SIM - just disable data and set the eSIM as your primary data line.

You don't have to remove it. Once your data plan expires, the eSIM simply stops providing data. You can leave the dormant profile on your phone and reuse it next time by purchasing a new plan, or delete it from cellular settings to free up an eSIM slot.

eSIMno partners directly with local operators in over 200 countries, eliminating intermediaries. This direct relationship lets us offer competitive pricing, extensive coverage, and faster activation than resellers who route data through third parties.

Your eSIM keeps its validity period running whether you're using it or not - pausing your trip doesn't pause the timer. If you return home, the eSIM stays dormant on your device until you travel again or it expires. You can disable it in cellular settings to avoid accidental usage.

eSIMs use ground-based cellular networks, so they don't work in flight or at sea outside coastal coverage. They activate as soon as you connect to a partner network on land. For in-flight or maritime data, you'll need the airline or ship's onboard Wi-Fi.

Yes. Modern iPhones and Android devices support multiple eSIM profiles - typically 5 to 8 stored profiles, with 1 or 2 active simultaneously. You can install eSIMs for different countries and switch between them in settings without removing any.
