Best eSIM for Spain
Five providers actually worth considering, compared without the marketing gloss.
| Provider | Short plan | Long plan | Verdict |
|---|---|---|---|
| Airalo | 1 GB / 7 days$4.50 | 20 GB / 30 days$26 | Biggest catalogue and the most predictable app. Data only. |
| Holafly | Unlimited / 5 days$19 | Unlimited / 30 days$64 | Genuinely unlimited, genuinely pricier. Worth it if you tether a laptop. |
| Yesim | 3 GB / 7 days$8 | 20 GB / 30 days$24 | Regional EU packages — the pick if Spain is one country of several. |
| Nomad | 1 GB / 7 days$5 | 20 GB / 30 days$25 | Frequent promo codes; clean, simple app. |
| Saily | 1 GB / 7 days$4 | 20 GB / 30 days$23 | Budget option from the NordVPN family. |
Prices are indicative and move with promotions.
Setting it up in three steps
- Buy at home, on wifi. Scan the QR code and add the plan — it takes about five minutes.
- Activate on landing. Switch the eSIM line on and enable data roaming for that line only.
- Keep the home SIM for SMS. Set the eSIM as your data line and your usual SIM for calls, so bank codes still arrive.
Common questions
Does an eSIM work everywhere in Spain?
Coverage rides on the national networks (Movistar, Vodafone ES and Orange). Cities, main railway lines and the coast are solid; remote interior valleys can be patchy on any provider.
Can I keep WhatsApp on my home number?
Yes. An eSIM adds a data line while your physical SIM stays active for calls and SMS, so WhatsApp keeps working on your usual number.
When should I install it?
Buy and install at home on wifi, then activate on landing. Most providers start the clock at activation rather than purchase — check before you tap.
eSIM or a local Spain SIM card?
Staying more than three weeks? A prepaid SIM from a Movistar or Vodafone shop works out cheaper per gigabyte — bring your passport, registration is required by law.
Will my phone support it?
Any iPhone from the XS onward, and most Android flagships of recent years, support eSIM. Handsets bought on a carrier contract are sometimes locked — check before you travel.
