BRITAIN’S mobile phone operators should be forced to set clearer rules on data roaming in the European Union, the MoneySavingExpert.com website has said.

The website, founded and led by consumer rights champion Martin Lewis, has called on telecoms regulator Ofcom and the government to tighten the regulations after some post-Brexit consumer protections expired.

In a new report, MSE warned that because a range of roaming-related legal obligations for operators ended on June 30 this year, firms no longer have to send customers a text message with pricing details when they begin roaming, operate a monthly cap on data roaming fees or provide protection against inadvertent roaming.

Some of Britain’s biggest mobile phone networks have reintroduced data roaming charges in Europe since the country’s withdrawal from the EU, despite previously promising not to.

Mr Lewis said the companies could not be trusted to regulate themselves and called on the government and regulators to step in.

“I’ve no faith in mobile firms to self-regulate,” he said. “When we left the EU, they promised not to reintroduce European roaming charges … yet most of the big networks have broken that promise.”
