# Travel eSIM, roaming or local SIM: which is cheaper?

Updated 12 November 2026. Page: https://findbestesim.com/blog/esim-vs-roaming-vs-local-sim

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 and local SIM compared:

|  | 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.
