Turn Off VPN

If you use a VPN service on your iPhone, you may get an error message saying that you need to update to use cellular internet on your iPhone. Because of this, you should turn off the VPN on your iPhone and check again to see if you can use cellular internet.

Data Roaming Should Be On

Did you check to see if data roaming is turned on on your iPhone or not? Well, it’s possible. That’s why you need to make sure you turn on data roaming by taking these steps:

So, we suggest that you try changing the software on your iPhone and see if that fixes the problem. To update your iOS, go to Settings > General > Software Update and download and install the current version of iOS.

Check to See if the Internet is Down Where You Are

There is a good chance that you are getting this iPhone error message because the internet isn’t working in your area and you need an update to use cellular data.

So, to be sure, if you can, try using your present SIM card on any other device to see if it connects to the internet or not.

But if it doesn’t connect to the internet on a different device, you have no choice but to wait until the network shutdown problem in your area is fixed.

Take Out and Put Back in the Sim Card

Try taking out your SIM card and putting it back in. Many people have said that this fixed this kind of mistake for them.
