SIM card / eSIM in Belgium: How much does it cost? Where to buy it?
For those who have a mobile plan from France, here’s some great news. Since Belgium is a member of the European Union, you won’t have to pay any roaming fees. You’ll be able to use your French SIM card to connect to the internet, send texts, or make calls, just as if you were still in France.

If you don’t have a French SIM card, here are a few solutions below.
Buy a SIM card before you leave
Here’s a convenient option: you can buy a SIM card before you leave.
Once purchased, it will be delivered right to your doorstep. Once you arrive in Belgium, all you have to do is pop it into your phone.
On Amazon, for example, you can find SIMs valid in all European countries (see the offer).
Buying an eSIM for Belgium
If your phone supports eSIM, this is really the most convenient solution. In just a few clicks, you get a digital SIM card that’s ready to use immediately.
For example, with our partner Holafly (check out the offer), you can get a deal offering unlimited internet access for 5 days for just €19 (longer-duration offers are also available).
If any of these offers catch your eye, feel free to use the promo code TOURDUMONDE5CONTINENTS.
Buying a SIM card in town
As you wander around, you’ll easily come across newsstands, phone shops, etc., selling prepaid SIM cards.
For example, this Lyca Mobile offer that gives you 300 GB (!!!) of data for €30.

Buying a SIM card at the airport
Since I arrived by land, I didn’t get a chance to check out the deals at Brussels airport.
