It is understood that the UK networks will still allow us to use our phones as we would at home but until brexit does or does not happen then no one is in a position to know.

O2's statement on this:
We’re committed to providing our customers with great connectivity and value when they travel overseas. We currently have no plans to change our roaming services across Europe. We will be working closely with the government and other European operators to try and protect the current arrangements so our customers can continue to enjoy free EU roaming once Britain officially leaves the EU.
