Why Does My Phone Say Could Not Activate Cellular Data Network? [Solved]
It’s possible you can’t connect to cellular data networks because you’ve turned off cellular data. To fix that, go to Settings > Cellular > move the Cellular Data slider to on/green. If the slider was already set to on/green, try moving it to off/white, waiting a few seconds, and then putting it back to on/green.12 Nov 2021
