Welcome to Vodafone Community
As anyone else come across this issue ,my sure signal has broken had it over 4 years ,the Vodafone IT said just switch to Wifi calling ,which i did do ,but now when i go out in my car ,my everyday duty ,the No signal come up and can not recieved or send phone calls ,also no mail text etc ??
If you turn Off wifi in your phones connection settings what happens then @Bradda ?
Is this happening everywhere you go, intermittently or permanent.
As a process of elimination can you try your sim card in another phone please to help rule out a phone or sim card issue ?
Customer service can check your account for any issues
It would also be worth just checking in your myvodafone that no bars have been activated.
