eSIM or Roaming: What to Choose for Belgium?
Special Case: French Travelers in Belgium
If you're French and traveling to Belgium, your French plan works normally thanks to free EU roaming. EU roaming applies WITHIN the EU, so from France to Belgium, you benefit from your plan without extra cost. You generally don't need an eSIM except for heavy usage or extended stays.
When an eSIM is Recommended
The Belgium eSIM is mainly intended for international tourists:
- International tourists: visitors from Europe, America, Asia, etc.
- 1+ week stays: avoid international roaming fees
- Heavy usage: streaming, video calls, hotspot
- Plans without roaming: some international carriers charge expensive roaming in Belgium
