Prepaid data abroad: the complete comparison

Traveling or visiting family abroad: how do you sort out prepaid data without paying a fortune in roaming? In the past you'd buy a local SIM card or an expensive roaming bundle. Today, an eSIM is the modern, cheaper way to get prepaid data abroad. Here's how the options compare.

The old way: local SIM card or roaming bundle

For years you had two options outside your own bundle: buy a physical prepaid SIM on the spot (queuing, language barriers, a new phone number) or add an expensive roaming bundle through your own provider. Both options cost time or money — sometimes both.

eSIM: the modern way to get prepaid data abroad

An eSIM is a digital SIM card you buy online in advance and activate with a QR code. No physical card, no new phone number needed — your existing SIM stays active for calls and texts, while the eSIM handles your mobile data at your destination.

The comparison in short

• Local SIM card: cheap, but time-consuming and sometimes tricky without the local language.
• Roaming bundle via your provider: easy, but often expensive with a limited data allowance.
• eSIM (prepaid data abroad): sorted online before you leave, active the moment you land — no surprises on your bill.
• Dual-SIM: with an eSIM alongside, your regular number stays reachable at all times.

Tip: install your eSIM at home over wifi and only turn on data roaming once you've arrived at your destination.
