What should you check in a Spain eSIM?
- Networks and 5G: Check which networks your eSIM runs on and whether it can use 5G. eSIMology's plans use the networks above, with 5G where the network offers it.
- Data size and top-ups: Match the plan to your days and use. For a 7-day trip, 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, and you check data left on a web page, with no app.
- Speed after the daily allowance: Once a daily allowance is used up, the speed drops to a set rate. eSIMology prints the speed on every plan: 512 Kbps after the daily allowance. If you use a lot of data, pick a larger daily allowance, such as 10 GB a day, or a fixed plan such as 50 GB for 30 days.
- Where your data goes: Your data reaches the internet through France, Netherlands or United Kingdom.
Fixed GB, daily or unlimited: which Spain eSIM fits your trip?

- Two weeks of heavy use: Heavy use is 2 GB a day for 15 days; standard use is 10 GB for 30 days. Once the daily allowance is used, speed drops to 512 Kbps.
- A month of heavy use: Heavy use is 2 GB a day for 30 days. eSIMology's daily allowances go up to 10 GB a day, and its largest 30-day fixed plan is 50 GB.
