Why This Guide Exists

When I first moved to Spain in 2021, I spent way too much money on mobile data. The local options were confusing, and I kept falling for expensive tourist traps. After three years of trial and error, switching between providers, and testing different methods, I've finally figured out what actually works.

This isn't a generic comparison site. These are real methods I've used personally, with actual costs, real experiences, and honest pros and cons. Whether you're a digital nomad, expat, or just visiting, this guide will save you money.

I've tested over 15 different top-up methods across Madrid, Barcelona, Valencia, and smaller towns. Here's what actually works.

Quick Money-Saving Tips

  • Avoid topping up at airports and tourist areas - prices are 30-50% higher
  • Look for "recarga" promotions during holidays - I've saved €10-15 per month this way
  • If you're staying 3+ months, consider a contract - it's often cheaper than prepaid
  • Some online platforms offer cashback - I've earned back over €200 in two years
  • Check coverage maps before choosing - rural areas have huge differences between providers
