You can deactivate international roaming on Vodafone UK by activating a 'Data Roaming Bar' through the My Vodafone app or website, which stops your SIM from connecting to any foreign networks. Alternatively, call 191 and ask customer services to place a roaming bar on your account. This guide explains both methods and clarifies the difference between network-level blocks and handset settings.
The same steps work on the My Vodafone website if you prefer a desktop browser. Changes take effect within a few minutes. Remember to reverse this before travelling if you later decide you need roaming.
If you'd rather speak to someone, call 191 from your Vodafone mobile (free from the UK) and ask the adviser to add a roaming bar to your account. From abroad, dial +44 7836 191191. The adviser will confirm the bar is active before you hang up. This method is useful if you're not confident navigating the app or if you want immediate confirmation.
A roaming bar is a network-level restriction. Once active, your SIM card cannot register on any foreign mobile network, which means no calls, no texts and no data when you leave the UK. Your phone will display 'No Service' or 'Emergency Calls Only' abroad. Wi-Fi still works normally, so you can use WhatsApp, email and other internet services wherever Wi-Fi is available.
This is different from the 'Data Roaming' toggle in your phone's settings. That handset option only prevents mobile data usage. Calls and texts can still connect (and cost money). If your goal is to avoid all charges, the Vodafone account-level bar is the safer choice.
If you want to allow calls and texts but block data, adjust your phone's settings instead:
This approach lets you make emergency calls or send texts without risking a large data bill. You'll still pay standard roaming rates for those calls and texts unless your plan includes them.
Since 31 December 2020, EU roaming rules no longer apply to UK networks. Vodafone reintroduced daily charges for European travel: £2.57 per day in Zone B (47 European destinations) for customers who joined after 11 August 2021. Older customers on legacy plans may still have inclusive roaming, but it's worth checking your specific terms in the My Vodafone app under 'Plan Details'.
If you're not planning to use your phone abroad, or if you'll rely entirely on Wi-Fi and a local SIM, deactivating roaming prevents accidental charges. This is particularly relevant near borders (south coast of England, Northern Ireland) where your phone might latch onto a French or Irish mast without you realising.
"Since 31 December 2020, the EU rules on roaming charges ceased to apply in the UK. This means that the amount your mobile provider can charge you for using your mobile phone in EU countries is no longer capped."
Vodafone splits the world into four zones. Zone A (Republic of Ireland, Isle of Man, Iceland, Norway) is included free on all Pay Monthly plans. Zone B covers 47 European countries and costs £2.57 per day unless you buy an 8-day or 15-day pass. Zones C and D include destinations like the USA, Australia and Turkey, with daily charges between £6 and £7.86.
All zones are subject to a 25GB monthly fair use limit. If your UK plan offers more than 25GB, you can't use the extra allowance abroad without paying £3.84 per additional gigabyte.
Inadvertent roaming is common in coastal areas and Northern Ireland. From 1 October 2024, Ofcom requires networks to send an alert when you start roaming, but you can take extra precautions. Manually select 'Vodafone UK' in your phone's network settings (usually under Settings > Mobile Networks > Network Operators) to stop automatic switching. Vodafone also made Republic of Ireland roaming free for all customers to reduce bill shock in Northern Ireland, though the 25GB cap still applies.
Is roaming automatically enabled on my account?
Yes, for most Pay Monthly customers. The question is whether your plan includes free roaming in your destination or charges a daily fee. Check 'Plan Details' in My Vodafone.
Can I reactivate roaming after I've turned it off?
Yes. Go back into the My Vodafone app, find 'Data Roaming Bar' under 'Manage Controls and Limits', and toggle it off. Changes take effect within minutes.
What if I'm abroad for several weeks?
Vodafone's fair use policy allows periodic travel. If you spend more than 62 days abroad in any four-month period and use more data abroad than in the UK, Vodafone may apply surcharges or ask you to change to a local plan.
Will I still receive calls and texts if I deactivate roaming?
No. A roaming bar blocks all network activity abroad. Callers will hear a standard unavailable message. If you only want to block data, use your phone's data roaming toggle instead.
