No Service when away from WiFi

[MikeNas_1036139]

Whenever I’m away from WiFi, my iPhone says No Service.  I can’t make or receive calls, send texts, or do anything that depends on phone or internet access.   When I’m at home or anywhere else where I can connect to Wi-Fi, everything works fine.  
This has been going on for weeks - before then, it was fine.  
Any advice, please?  
Thanks

@MikeNas_1036139  Firstly, do a Network Status check to see if there is a local mast problem.

Are you also not able to make calls or send texts when elsewhere? If network status is OK then I wonder if there is a problem with your sim in that case - you could ask for a replacement.

Hi are you saying that when you have WiFi you can make calls and send texts ?
