Might you be using Dual SIM? Cellular data is only available for one line.
Check Settings > Cellular > [Cellular Data and Cellular Data Options].
Apple doesn't provide mobile data. Your carrier does. Elevate this with your carrier to a higher level technical support person. Do you have a VPN on your iPhone? If you do, get rid of it and see if that helps.
That has fixed it, thanks so much!
Yes the VPN. Thanks again.
Thanks for your suggestion!
You’re welcome. Glad it’s resolved 😃
You're welcome. Glad to help.
Great. I'm assuming it was the VPN? Now, never put one on your iPhone again.
