Why This Guide Exists
When I moved to Spain in 2022, I spent weeks researching mobile operators. Every website gave me the same generic comparison tables and marketing promises. None of them told me about the hidden fees, the customer service nightmares, or which network actually works in the mountains outside Granada.
I've now used Movistar, Orange, and Vodafone extensively across different regions. I've dealt with their customer service, navigated their contracts, and experienced their network quality firsthand. This guide shares what I've learned so you don't have to make the same mistakes.
Quick takeaway: There's no single "best" operator. It depends on where you live, how much data you need, and whether you value customer service over price. But I'll help you figure out which one fits your situation.
