The right choice depends on the traveller’s home operator, the territory actually visited and the services included in each option. In this case, Brexit and voluntary carrier policies deserve an explicit check.
Compare the complete trip rather than one headline price: Brexit, voluntary carrier policies, fair-use limits can change which choice is cheaper and easier in practice.
NoveSIM travel eSIMs are data-only and do not include a local number, ordinary voice minutes or carrier SMS. Maps and messaging use the travel data line, while the home SIM keeps its own provider and roaming terms.
Quick answer: EU roaming is not legally guaranteed in London after Brexit. Some European operators still include the United Kingdom voluntarily, while others apply a daily pass, a separate allowance or standard international roaming rates.

Open the home operator’s current destination table and find the United Kingdom explicitly. Do not infer inclusion from an old EU tariff name. Record the data limit, pass trigger and expiry for the exact subscription. Check live destination coverage and validity.
Account for Fair Use and Plan Exceptions
An operator that includes UK roaming may impose a lower roaming allowance than the domestic bundle. Older, business, prepaid and promotional plans can follow different rules, so the account’s own terms take priority over general advertising. Use the travel-data allowance guide to estimate these activities.
Separate Mobile Data from Calls and Voicemail
A data pass does not necessarily cover calls to UK numbers, incoming calls or voicemail retrieval. Check each service and disable conditional forwarding if the carrier confirms that it could create unwanted roaming charges. See keeping the primary number with eSIM data.
Prepare London Navigation before Arrival
Save the accommodation address and first rail or Underground route offline. If the home plan is unclear or expensive, install the UK eSIM in advance and test it after arrival before leaving the airport or station. Before buying, verify the exact device model.
Separate Data from Calls and Messages
NoveSIM travel eSIMs are data-only. They support maps, browsing, messaging and internet-calling apps, but not a local number, ordinary voice minutes or carrier SMS. Keep the primary SIM only when its roaming costs are understood. Use the device compatibility checks when the handset variant is uncertain.
Prepare a Reversible Backup
Save essential bookings and addresses offline. Install the eSIM on secure Wi-Fi, retain the original SIM and avoid destructive troubleshooting; this keeps both the travel plan and diagnostic evidence available.
Practical Checklist: Does EU Roaming Work in London After Brexit
Compare Brexit with voluntary carrier policies using the exact dates, route and services required. Current operator or plan terms take priority over a broad regional label or an old price example.
A Safe Final Connection Check
- Confirm that the travel eSIM is still visible and enabled.
- Select it for Mobile Data without changing the voice line by accident.
- Turn on Data Roaming for the travel line and turn off automatic data switching.
- Wait for Automatic Network Selection before testing a normal website.
- Enter data.esim only when the NoveSIM instructions require a manual APN.
If the result is still wrong, keep the installed eSIM and record the device model, present location, selected lines and visible network status. Send the recorded settings to NoveSIM Support without exposing the QR code or activation credentials. Remove the profile only if Support explicitly requests that step.

Check Brexit and voluntary carrier policies before enabling home-line data. Leave mobile data disabled on the home line unless its roaming allowance has been confirmed; calls and texts follow that operator’s separate tariff.
