Thank u. I have friends that work on the airport with S8 and Note8, on a different network and they don't have any problem. I'm speaking to EE see if they can trace use issue. Thanks again.
No problem, I hope you're able to get it sorted. To give you a better idea of where the issue is stemming from you can ask your friend to swap SIMs with you temporarily. If he is able to connect via Mobile Data on your device, or if you re unable to connect on theirs, then this would suggest that it is a network issue (or vice versa). For further support you can contact the Samsung helpdesk on 0330 726 7864 or visit your nearest authorised Support Centre by checking the following link, selecting 'Mobile Device' and entering your post code.
