Unlimited Data SIM Spain: eSIM & Physical Card Options 2026
Finding unlimited data in Spain is easier and cheaper than you think. Whether you're a digital nomad, an expat, or planning an extended stay, Spain offers some of the best mobile data deals in Europe. Knowing which option best suits your needs can save you a lot of money.
Plans start from just €10.00/month with local Spanish operators, and you can choose between traditional SIM cards or eSIM for instant activation. This guide will help you understand your options and choose the right plan for your situation.
Which Type of Unlimited Data Plan is Best for Your Situation?
When looking for unlimited data SIM Spain options, the best choice depends on how long you're staying. Spain offers two main types of unlimited data plans: contract plans with better long-term value, and prepaid plans for short visits. Contract plans typically use physical SIM cards, though some operators like Digi and Vodafone also offer eSIM options. Prepaid plans are widely available as eSIM for instant activation.
Contract plans start from just €10.00/month and offer genuinely unlimited data with no commitment period, making them ideal for expats and long-term visitors. Prepaid plans are more convenient for tourists but typically cost more per GB. Here's how to choose.
Staying Several Months or Longer? Choose Contract Plans
For extended stays, contract plans with unlimited data are the best option. Starting from just €10.00/month, they offer unbeatable value with no commitment period, so you can cancel anytime without penalties.
Contract plans give you:
- Genuinely unlimited data with no commitment period
- A Spanish phone number
- Better long-term value
- No surprise charges or top-ups needed
Documentation requirements: EU/EEA citizens typically only need their passport. Non-EU citizens generally need a residence permit (TIE/NIE). Requirements vary by operator, so check with your chosen provider.
eSIM availability: Most contract plans use physical SIM cards, but some operators like Digi also offer eSIM options for their unlimited contract plans.
Short Stays (Under 30 Days)? Choose Prepaid Plans
If you're only visiting Spain for a short period, prepaid plans may be more convenient, though they're typically more expensive than contract plans for the same amount of data.
Documentation requirements: Prepaid plans have simpler requirements. You only need your passport for registration, with no residence permit, Spanish bank account, or proof of address needed.
eSIM availability: Unlike contract plans, almost all prepaid plans in Spain are available as eSIM, making them ideal for instant activation before or upon arrival.
