In my experience, the right SIM card makes the trip smoother and far less stressful.
What I Look For Before Buying
Before I choose a SIM card, I check a few important things:
- Coverage: I make sure it works in the countries I’m visiting, not just one destination.

How I Compare Data Plans

- Whether the card includes 4G or 5G access in the countries I’m visiting
