Frequently asked questions
How much data should you choose?
For maps, messaging and light browsing, a few GB are usually enough on a short trip. For social media, video, remote work or video calls, go for a larger allowance.
Can I keep my usual number?
Yes. On a Dual SIM compatible phone you keep your usual line for calls and texts, and use the Décall eSIM for mobile data.
Is my phone compatible?
eSIM works on recent eSIM-compatible smartphones that are not carrier-locked. If you are unsure about your model, message us before buying.
Check your home plan first
Since Brexit, the UK has left automatic EU roaming, yet most French operators still treat it as a Europe destination with a capped data allowance. Check your plan before buying anything: if the UK is included and your allowance is enough, you need nothing else.
When an eSIM genuinely helps
- •Your plan excludes the UK, or bills roaming beyond a small quota.
- •You regularly exceed the included allowance: out-of-bundle charges add up fast.
- •You are staying several weeks: included roaming is designed for occasional trips, not long stays.
Which plan for a stay in the UK
For a weekend in London, 3 GB is enough. For two weeks with daily navigation, 10 GB is more comfortable.
Does my home plan already work in London?
Often yes, with a limited data allowance. Terms vary by operator and plan, and can change: check your account before you travel. We would rather tell you than sell you something you do not need.
Which networks are used in the UK?
O2 and EE on 5G, Three on 4G. Coverage is excellent in cities, patchier in the Scottish Highlands and rural Wales.
