Planning a trip abroad often involves considering the best solution to stay connected. Between roaming, local or international SIM cards, and eSIMs, it can sometimes be difficult to find your way. This article guides you to make the most suitable choice for your needs and budget.
What is roaming?
Roaming is the service offered by your phone operator to allow the use of your number abroad. This includes calls, SMS, and mobile data, often at increased rates. If your trip is short and you don’t plan to use much data, roaming can be a simple, albeit expensive, solution.
When is roaming advantageous?
- For short trips where you use little data.
- If your operator offers plans with included roaming.
Be aware, however, of hidden fees and overage charges, which can quickly add up to a heavy bill.
What is a local SIM card?

A local SIM card is a physical card you purchase once you arrive in your destination country. It allows you to get a local number and benefit from advantageous rates for calls and data.
Advantages of local SIM cards:
- Generally more competitive rates for calls and data.
- No long-term commitment.
- Availability in local stores and airports.
However, these cards can become impractical if you travel to multiple countries, as they often only work within the area where they are purchased.
What is an international SIM card?
International SIM cards are designed for frequent or long-term travelers. They give you the opportunity to use calls, SMS, and data in several countries without having to change cards.
Advantages:
- Convenience for multi-country travel
- Often offers a single solution to stay connected
On the other hand, they can be more expensive to purchase and often require prior activation or specific recharges.
Why not choose an eSIM?

- Simple and quick installation: activate your plan in minutes.
- No physical card needed; you can combine multiple plans.
- Ideal for multi-destination trips.
- No risk of losing a physical SIM card.
With eSIM, you can easily switch between different plans and stay connected worldwide without logistical complications. Being virtual, it is the most modern and flexible solution for travelers.
