Important details

Option 1: Roaming

The simplest but most expensive option. Free in the EU, but €5-20 per GB outside. Advantages: No setup necessary. Disadvantages: Extremely expensive outside of EU, no cost control, often throttled speed. Conclusion: Only recommended as an emergency solution.

Option 2: Hotel WLAN / Public WLAN

Free, but not mobile and often insecure. Advantages: No costs. Disadvantages: Only available in fixed locations, often slow, security risk in public networks, no navigation possible on the move. Conclusion: ok as a supplement, but not as the main solution.

Option 3: Local SIM card

Cheap, but inconvenient. You buy a SIM at the airport or in the store. Advantages: Cheap local rates, works on any cell phone. Disadvantages: Card change necessary, language barriers, loss of time, only for one country. Conclusion: Good for long-term stays in one country.

Option 4: Pocket WiFi

A mobile WLAN router that you rent. Advantages: Multiple devices at the same time, good coverage. Disadvantages: Carry extra device, expensive (€5-15 per day), needs to be charged, pick-up/return required. Conclusion: Only interesting for groups or families.

Option 5: eSIM (recommendation)

The most modern and convenient solution. Advantages: Digitally activated, no need to change cards, cheap (from €4), can be purchased before traveling, regional rates for several countries, your number remains reachable. Disadvantages: Smartphone must support eSIM, WLAN required for installation. Conclusion: The best overall solution for most vacationers.

Which trip needs what?

Beach vacation

For a relaxed beach vacation, you mainly need Internet for WhatsApp, Instagram and navigation. 3-5 GB are easily enough for 1-2 weeks.

Recommendation: Airalo or Nomad with a small package from 4 €.

City trip

Internet is particularly important on city trips: navigation, Google maps, finding restaurants, Uber. A little more data volume is worthwhile here.

Recommendation: Airalo with 5-10 GB or Holafly Unlimited.

Adventure vacation

Network coverage is crucial when hiking, on safari or on remote islands. Choose a provider with a good local network.

Recommendation: Check the network coverage in the Airalo app before you buy.

Family vacation

With children, you often need more data - for streaming in the car, navigation and communication. Unlimited tariffs are ideal here.

Recommendation: Holafly Unlimited for the whole family via Hotspot.
