For a longer holiday in one destination, the key is a data plan with enough days and gigabytes for your travel style.

Which Crete eSIM should you get for 21 days?
For three weeks in Crete, start with an eSIM that lasts more than 21 days. VoyageSIM's Greece eSIM product currently lists 30-day data plans with 3 GB, 5 GB, 10 GB and 20 GB, with additional options shown on the product page.
3–5 GBMaps, messaging and lighter browsing
10 GBRegular mobile data use and social media
20 GB+More intensive usage and hotspot needs
These are planning guidelines rather than guaranteed allowances for a particular lifestyle. Streaming and video calls can consume significantly more data. Try the VoyageSIM data calculator and check the product page for updated prices and validity details.

Internet in Heraklion, Chania and Rethymno
A data eSIM can help with transport directions, restaurant searches, accommodation details and contacting friends or family while travelling around Crete.
Actual coverage and speed vary with the local partner network, buildings, terrain and your location. No cellular provider can guarantee service everywhere on Crete, particularly in isolated or mountainous areas.

Greece-only eSIM or a Europe travel eSIM?
If your holiday is entirely in Crete, compare the Greece eSIM first. VoyageSIM offers 30-day options for that country. If you will also visit Italy, Spain or other countries, consider a regional Europe eSIM, but only after checking that every destination is explicitly included in the plan you choose.
Choose according to your itinerary, not simply the number of countries in a plan's title. VoyageSIM prices are in Canadian dollars and the plans covered here are data-only.

How to install an eSIM for a three-week holiday
- Check that your phone is compatible with eSIM and carrier-unlocked.
- Pick a 30-day plan with enough data for your needs.
- Install on reliable Wi-Fi, following the VoyageSIM installation instructions.
- Check the plan's activation and validity policy.
- On arrival in Greece, select VoyageSIM for mobile data and review your Canadian carrier's roaming settings.
A data-only eSIM does not include a local phone number, traditional cellular calls or SMS. You can normally keep your primary line on a suitable phone, but your Canadian carrier may charge for certain services. WhatsApp, iMessage and other Internet-based services work according to your connection and settings.

Stay connected beyond the hotel Wi-Fi
Your hotel's Wi-Fi can be convenient, but it might not be available while driving, touring villages or exploring beaches. A Greece eSIM gives you another way to connect when a supported local network is available.
For a three-week trip: make sure the validity period covers your stay, save important travel details offline and monitor your data usage. Downloading offline maps is still a smart backup.
VOYAGESIM · FAQFrequently asked questions
Is a 30-day eSIM suitable for 21 days in Crete?
Yes, a 30-day option is generally a better fit than a 15-day option for a three-week trip. Check your selected plan's validity and activation terms.
Will a Greece eSIM work on Crete?
Crete is part of Greece. A Greece eSIM can use supported local mobile networks on the island, with coverage varying by location.
