We're aware of a network wide issue that was affecting services, and we believe this has now improved for most customers, so please restart your phone and attempt to call. We sincerely apologise for any inconvenience caused, and really appreciate your patience.
Had same issue and also once last year . Aside from possible network issues could be due to recent iOS upgrade . To resolve try following
go to settings - select general - scroll to bottom and select reset or transfer I phone . At bottom select reset ( ignore set up new iPhone or erase all data) then choose reset network settings….phone will power off then back on again . Hopefully it will then reconnect to network
Hi Paul, thanks for your reply. But I have an android phone, so could I give me process of what to do pleeeeeeeeease!!!! Having no network is the worst!!! 😭
