Yes, your mobile network supports international roaming in most countries worldwide. When you travel abroad with your mobile network SIM, your phone connects to a partner network in that country. Depending on your plan, data roaming may be included in your monthly allowance or charged at an additional rate per megabyte or day.

Always check your mobile network plan details before travelling. Roaming charges vary significantly between destinations and plan types. The UK APN Hub has a full list of roaming destinations and rates.

Post-Brexit: EU roaming charges may apply on UK networks
Since leaving the EU, UK networks can legally charge for EU roaming. Always check your plan's roaming terms before travelling. Some plans include free EU roaming; others charge per MB at high rates. Turn on data roaming only after confirming your tariff covers it — unexpected bills can be very large.

Enabling data roaming before you travel

Most Android devices: Settings → Network & Internet → Mobile Network, toggle Data Roaming. Samsung: Settings → Connections → Mobile Networks → Data Roaming.

iPhone: switch on Data Roaming through Settings → Mobile Data → Mobile Data Options.

Note: Enabling data roaming does not turn on internet automatically — your mobile network plan must include roaming, or you may be charged pay-as-you-go roaming rates.

Checking roaming costs on UK networks

The phone usually uses the same APN abroad as in the UK. If data doesn't work, try manually picking the local partner network via Settings → Mobile Network → Network Operators → Search manually, then confirm the APN settings still match your usual configuration.

Fastest way to apply new APN settings
After saving, turn aeroplane mode ON for 10 seconds, then turn it OFF. This forces an immediate network re-registration — quicker than a full restart and equally effective.

Fixing data not working abroad on UK SIMs

No data abroad: Confirm data roaming is enabled in your phone settings. Check your mobile network plan includes the destination country. Try manually selecting a local partner network. Toggle aeroplane mode off and on.

If the roaming bill seems excessive, set a data limit and disable background app refresh — apps can rack up data passively.

Calls not connecting abroad: Make sure Voice Roaming is also enabled if separate from data roaming. Some countries require a specific dialling prefix — check your mobile network roaming guide for your destination.

Download offline maps before you leave. Connect to hotel or café Wi-Fi for heavy data use. Use your network's app to monitor roaming usage, and consider a travel bolt-on or daily data pass to avoid unexpected charges.
