Are you sure you were roaming, rather than connecting to free wifi which is available in many areas? Either way, if you have TalkTalk mobile and wish to use it abroad you should get in touch to enable it before travelling:
From the 29th of March our TalkTalk Community will move to peer-to-peer support and the TalkTalk team will no longer be here to support with queries. Don’t worry we still have plenty of ways to reach out if you need to speak to TalkTalk directly. For more details check out the link here: How to contact TalkTalk Broadband - Help & Support.
