Mobile data - slow or not working

[Avonshole]

Hi, my mobile is either really slow or just not working at all since I switched phones. My colleague is on the same network and it’s working fine completely for him. What should I do?

Thank you for that information. Now that we have passed data protection we will chat via the public thread. 

Can you confirm if the data issue is happening in different area's? If not, can you confirm the postal code of the specific area this is happening in?

Can you confirm if you have changed handset recently?
