Vodafone is delaying the reintroduction of roaming charges in Europe by three weeks.
The phone network had planned to bring in post-Brexit roaming fees on 6 January, matching other networks who plan to do so in 2022.
But it said more time was needed for testing, and the change will now come in at the end of January.
EE has also delayed resuming its roaming charges, which were planned for January, until March.
Before the UK left the EU, users were able to use their calls, texts, and data allowance in their mobile plans in any EU country. But the EU trade deal of December 2020 gave mobile operators the option of reintroducing charges.
The Three network has also said it will bring in roaming charges between the UK and Europe, though their change is planned for May 2022.
That means that of the largest mobile networks, only O2 has not announced any plans for the reintroduction of roaming fees.
The £1 a day charge is Vodafone’s best price, and only applies when bought in an eight or 15-day bundle. The usual planned price is £2 per day in fees, matching EE and Three’s planned pricing.
EE said the shift in its plans was caused by unspecified technical delays.
