Martin Lewis has issued a warning to holidaymakers who use their mobile phone abroad.
The Money Saving Expert has said UK travellers could be hit with unexpected mobile roaming costs for using just a minute of data abroad. Firms were previously banned from charging additional fees to use your UK allowance while holidaying in the EU.
However, Brexit has meant holidaymakers are no now no longer protected from these charges. Many networks have reintroduced roaming costs and Martin has urged travellers to be aware of how much each company is charging.
