What should you check in a Greece eSIM?
- Networks and 5G: eSIMology's plans run on Vodafone and Wind, with 5G where the network offers it. Before you pay, eSIMology checks the phone you're on at checkout.
- Plan size: For a 7-day trip, light use (about 1.8 GB in all) suits 2 GB for 15 days, standard use (about 4.9 GB in all) suits 5 GB for 30 days, and heavy use (about 12.6 GB in all) suits 2 GB a day for 7 days. Most plans can be topped up if you run short.
- Speed after your daily allowance: Once a daily allowance is used up, eSIMology's plans drop to 512 Kbps, and that speed is printed on every plan. At that speed, video will be slow, so heavy users should choose a larger daily allowance or a bigger fixed plan.
- Where your data goes: Your data reaches the internet through France, the Netherlands or the United Kingdom.
Fixed GB, daily or unlimited: which Greece eSIM suits your trip?
- A 3-day Athens break: Uber and FREE NOW are the local ride apps. For light use, eSIMology's 500 MB a day for 3 days suits you. For standard use, 2 GB for 15 days does, and it leaves spare data for later.
- A week across Santorini, Mykonos, Crete or Rhodes: Light use fits 2 GB for 15 days, standard use suits 5 GB for 30 days, and heavy use suits 2 GB a day for 7 days. Most plans can be topped up if you need more mid-trip.
- Two weeks of daily heavy use: Standard use suits 10 GB for 30 days, and heavy use suits 2 GB a day for 15 days. Not sure how much you use? Work out your data first.
- A trip where you want unlimited data by the day: Airalo and Holafly sell unlimited plans by the day for Greece in 3, 5, 7, 10, 15 and 30 day lengths. Saily offers them from 1 to 30 days, plus 90 and 365.
