eSIM vs Physical SIM
eSIMs (digital SIMs) work on iPhone XS/newer and most recent Androids. They activate instantly without swapping cards. Physical SIMs require a compatible unlocked phone but are cheaper per GB. For trips under 2 weeks, eSIMs are more convenient. For longer stays, physical SIMs save money.
Best eSIM Providers
Airalo offers the widest coverage with Europe-wide packages from $5 (1GB) to $42 (10GB). Holafly provides unlimited data from €19/5 days—best for heavy users. Ubigi integrates with Apple devices natively. Nomad is cheapest per GB for light users. All activate within minutes via QR code.
Pro Tip: Set up your eSIM before leaving home on WiFi. Troubleshooting abroad without data is frustrating.
Best Physical SIM Options
Orange Holiday Europe offers 20GB for €49.99, sold at airports and tobacco shops. Vodafone and Three (UK) have EU roaming. Lebara works across Europe with local rates. For single-country trips, local operators like TIM (Italy) or Movistar (Spain) offer the best value—typically €15-20 for 15-30GB.
EU Roaming Explained
EU law requires operators to offer roaming at domestic prices within the EU. This applies to SIMs purchased in any EU country. A Spanish SIM works in France, a German SIM works in Italy. The UK and Switzerland are exceptions—they're not in the EU and may charge extra.
Data Usage Realities
Maps and translation use minimal data (0.5-1GB for a 2-week trip). Social media with photos uses more (2-4GB). Video streaming burns through data quickly (1GB per hour). Download maps, translation packs, and entertainment before departure to reduce usage.
Airport Pickup vs Pre-Order
Airport SIM shops charge 20-40% markups. Pre-order eSIMs from home for better rates. If buying physical SIMs, city-center phone shops or supermarkets (Carrefour, Tesco, MediaMarkt) are cheaper than airports. Bring your passport—EU regulations require ID for SIM purchases.
