Travel eSIM, roaming or local SIM: which is cheaper?
Updated 12 November 2026
A travel eSIM is usually the cheapest simple way to get data abroad: you buy it online, install it before you leave and keep your own number for calls and texts. Roaming is the easiest but often the most expensive outside your home region. A local SIM can be the cheapest for long stays, but you need a shop, sometimes your passport, and a free SIM slot.
Side by side
| Travel eSIM | Roaming | Local SIM | |
|---|---|---|---|
| Price | Low, fixed in advance | Often high outside your home region | Often the lowest per GB |
| Setup | Online, a QR code, a few minutes | Nothing to do | A shop after you land, sometimes a passport |
| Your number | Keeps working next to the eSIM | Keeps working | Replaced, unless your phone takes two SIMs |
| Best for | Most trips | Short trips inside a region where it is included | Long stays in one country |
When roaming is the better choice
If your phone plan is from the European Union and you travel inside it, roaming is usually included at home prices, within a fair use limit. Some plans in other countries include travel passes too. Check yours before you buy anything.
Before you buy an eSIM
- Your phone must support eSIM and be unlocked. On most phones, dialling *#06# shows an EID number if eSIM is supported.
- Install the eSIM on Wi-Fi before you leave, then switch mobile data to it when you land.
- Keep your own line for calls and texts: WhatsApp and similar apps keep working on the eSIM's data.

Questions
Is an eSIM cheaper than roaming?
Outside the region your phone plan covers, almost always. Inside it, roaming may already be included.
Do I lose my number with a travel eSIM?
No. The eSIM adds a data line next to your own, which keeps receiving calls and texts.
Does WhatsApp work with a travel eSIM?
Yes. WhatsApp is tied to your account, not to the SIM that carries the data.
