What is an eSIM?
An eSIM (Embedded SIM) is a digital SIM card already built into many modern smartphones. Instead of inserting a physical card, you simply download an electronic profile and activate it on your phone.
Installation takes just a few minutes and can be done before your trip using a QR code or directly via the aloSim app.
What are the advantages of an eSIM?
Using an eSIM while traveling offers several advantages:
You avoid high roaming charges.
You don't need to remove your regular SIM card.
You can keep your primary phone number active.
You buy the plan before your trip, and it’s ready to use when you arrive at your destination.
It’s easy to add more data if needed.
For frequent travelers, it is a much more convenient solution than looking for a local SIM card after landing.
Is my mobile phone compatible?
Most smartphones released in recent years already support eSIM.
Compatible devices include many models:
iPhone XR and later.
Samsung Galaxy S20 and later (and various models in the A and Z series).
Google Pixel 3 and later.
Various eSIM-compatible models from Huawei, Motorola, Oppo, and Xiaomi.
Before purchasing a plan, always confirm that your device is unlocked for any carrier and is eSIM-compatible.
How does it work during the trip?
The process is quite simple:
You purchase a data plan for your destination country.
You install the eSIM on your phone.
You keep the eSIM installed until your trip.
When you arrive at your destination, the plan activates automatically and connects to a local mobile network.
As soon as you land, you have immediate Internet access to use maps, transportation apps, and hotel reservations, or to communicate via WhatsApp.
Why do we recommend aloSIM?
There are several eSIM providers on the market, but aloSIM stands out for its ease of use and international coverage.
Key strengths include:
coverage in over 200 destinations;
simple installation via the app or a QR code;
prepaid plans with no long-term contracts;
the ability to top up data whenever needed;
24/7 customer support.
Another appealing advantage is that many plans include free access to the Hushed app, allowing you to get an international number for calls and messages over the Internet.
When should I install the eSIM?
Ideally, you should install the eSIM before leaving home, while you still have access to a stable Wi-Fi connection.
This way, once you arrive at your destination, you simply need to turn on mobile data and start using the internet. In many cases, activation happens automatically as soon as your phone connects to the network in the destination country.
Is it worth buying an eSIM?
In our opinion, yes.
For international travelers, an eSIM is currently one of the most convenient and cost-effective ways to ensure worry-free internet access.
It saves you from queuing to buy local SIM cards, eliminates the risk of high roaming charges, and allows you to start using essential apps immediately upon arrival.
That is why we recommend this solution in practically every itinerary published on our website.
