My mobile Data appears not to be connected to anything.
It was working fine. I have only just noticed this in the past few days. My account shows that I have 9.98gb left. I changed my monthly contract commencing on the 4th March. (5gb plus 5gb rollover, which means I started with 10gb on the 4th March.)
Mobile Data is turned on. I have tried turning off and back on again, however no changes. I used to see the number 4 replace the wifi symbol at the top of the phone screen. Now all I see is the phone signal strength bars.
Phone works fine over any wifi I connect to.
