One part of international travel that has quietly improved over the last few years is mobile connectivity. Instead of searching for a local carrier after landing, I now install an eSIM before I leave home and activate it when I arrive.
The biggest advantage isn't just convenience. It's that your phone is already prepared before the trip begins.
With a traditional SIM card, you have to find a mobile store, compare plans, swap your existing SIM, and configure your device. During that time, you may not have access to maps, ride-hailing apps, or messaging services unless you can find public Wi-Fi.
An eSIM removes those steps. The mobile profile is downloaded digitally, allowing your device to connect to a supported network as soon as the plan becomes active. Because your primary SIM can remain in your phone, you can continue receiving calls or messages from your home number while using local mobile data for your trip.
This becomes especially useful when traveling across destinations like Mallorca, Ibiza, Tenerife, Gran Canaria, or Lanzarote, where reliable internet is essential for navigation, transportation, accommodation check-ins, and online bookings.
When comparing eSIM providers, I usually look beyond price. Network coverage, activation speed, hotspot support, and available data plans are just as important, especially if I'm working remotely or planning a longer stay.
If you're researching options for Spain's islands, AloOui has a useful guide that explains coverage across both the Balearic and Canary Islands, available plans, and how to activate an eSIM before your trip:
For frequent travelers, setting up connectivity before departure has become part of the travel checklist. It saves time after landing, reduces reliance on roaming, and makes it easier to stay connected from the first day of the trip.
