When does 48 plan to add 4G roaming? I have noticed for a few EU countries roaming no longer works for 3G as they are shutting down their 3G networks and replacing with 4/5G, and 48 only offer 3G roaming. This means I am only getting 2G/EDGE if I am lucky

the new EU rule 

Consumers now will have the right to the same quality of mobile internet abroad, as the one they have at home. Operators providing mobile services should ensure that consumers have access to use 4G
