Updated July 2026. The cheapest prepaid SIM card in Spain is **[Digi](https://www.digimobil.es)** at **EUR 5/month** (15 GB, unlimited calls, EU roaming). For 30 GB on the **[Vodafone](https://www.vodafone.es)** network, **[Lowi](https://www.lowi.es)** costs **EUR 8/month**. For the widest rural and island coverage, **[Movistar](https://www.movistar.es)** runs its own network at **EUR 15/month**. All plans include EU roaming and can be activated with just a passport or NIE.

## How does the score work?

Each plan receives sub-scores on four axes, then a weighted average produces the headline match number out of 100. The weighting reflects what mobile users in Spain consistently rank most decision-relevant:

- **Price (35%)**: monthly cost versus your stated budget. Plans over your cap drop sharply.
- **Data value (30%)**: GB included versus your stated monthly data need. Unlimited data scores full marks here.
- **Network fit (15%)**: matches your preferred operator. Set to "Any" and this axis cannot drag a plan down.
- **Feature match (20%)**: EU roaming, eSIM support, profile fit (newcomer, student, resident, tourist), and English customer support availability.
