Updated July 2026. Spain has no single nationwide student-only SIM brand, so the best value for students comes from the cheapest general MVNO plans. Digi costs EUR 5/month for 15 GB with unlimited calls. Simyo is EUR 7/month for 20 GB on the Orange/MasOrange network. Lowi is EUR 8/month for 30 GB on the Vodafone network. O2 gives the most data at EUR 10/month for 40 GB on the Movistar network. None require a Spanish bank account or long-term contract.

The best SIM card for a student in Spain depends on whether you prioritise the lowest price, the most data, or a familiar host network. Digi at EUR 5/month wins on absolute price.

Are There Student or Youth SIM Card Discounts in Spain?
Spain does not have a single nationwide student SIM brand comparable to some other European markets. Some regions offer the Carnet Joven (youth card) for under-30s, which carries discounts across various services. It has had at least one telecom tie-in: GigaJoven, a Vodafone-network promotion that offered a free mobile line for 6 months and then EUR 7.90/month for unlimited calls and 25 GB to Carnet Joven holders. As of July 2026, GigaJoven's own site lists that promotion as closed to new sign-ups, so there is no verified live Carnet Joven telecom discount to recommend right now. In practice, the cheapest general MVNO plans (Digi, Simyo, Lowi, O2) already undercut most advertised youth promotions on headline price, so comparing on price alone is usually the more reliable approach.
Which Student Plan Gives the Most Data?
O2 gives the most data among plans suited to students at 40 GB for EUR 10/month on the Movistar network. Lowi follows at 30 GB for EUR 8/month. If 40 GB is not enough, Pepephone offers unlimited data for EUR 12/month, though it is not specifically marketed at students.
How Much Do Student SIM Cards Cost in Spain?
Prices for the four plans compared here run from EUR 5 to EUR 10 per month. All include unlimited calls and EU roaming, which makes them significantly cheaper than an MNO contract plan for the same use case.
| Plan | Provider | Price | Data | Network |
|---|---|---|---|---|
| Digi 25 GB | Digi | EUR 5/mo | 25 GB | Movistar |
| Lowi 50 GB | Lowi | EUR 8/mo | 50 GB | Vodafone |
| Simyo 50 GB | Simyo | EUR 7.5/mo | 50 GB | Orange |
| O2 Movil 50 GB | O2 | EUR 7/mo | 50 GB | Movistar |

Frequently Asked Questions
Is there a dedicated student SIM card discount in Spain?
Carnet Joven, the youth discount card issued by Spain's autonomous communities, has had at least one telecom tie-in: GigaJoven, a Vodafone-network promotion offering a free line for 6 months, then EUR 7.90/month for unlimited calls and 25 GB. As of July 2026, GigaJoven's own site shows that promotion closed to new sign-ups ('Promocion finalizada'), so there is no verified live Carnet Joven telecom discount to point to right now. Absent an active discount, the cheapest general MVNO plans (Digi, Simyo, Lowi, O2) already undercut most MNO student promotions on headline price.
Which SIM card gives students the most data in Spain?
O2 gives the most data among the plans compared here at 40 GB for EUR 10 per month, running on the Movistar network. Pepephone offers unlimited data for EUR 12 per month if 40 GB is not enough, though it is not specifically marketed as a student plan.
How much does a SIM card cost for students in Spain?
Among plans open to students without age or enrolment restrictions, prices start at EUR 5 per month for Digi (15 GB) and range up to EUR 10 per month for O2 (40 GB). Typical range, verify current offers.
Can international students use these SIM plans in Spain?
Yes. None of the plans compared here require Spanish citizenship or a specific student visa type. Registration requires a passport, NIE, or DNI. For prepaid SIMs specifically, a passport is accepted by nearly all providers, so international students do not need to wait for their NIE card to arrive before getting connected, as of July 2026.
