Another way of getting wireless internet access on your smartphone is through mobile data. It is a better alternative in the absence of a Wi-F network and that you badly needed to browse the Internet. With mobile data, you’ll have the convenience of on-the-go access to the Internet, depending on how much data plan you’ve got. But there are just some instances when mobile data problems are encountered and so you wouldn’t be able to connect through it. Exceeding the data limit  that results in data capping as well as network signal issues are usually the main culprits. Data capping could result in slow or intermittent connection to the Internet. 

In worst scenarios, you could end up having no internet connection at all. To address this problem, I’ve mapped out a few suggested workarounds to eliminate software-related factors that caused mobile data to stop working on your iPhone XS.

If you still don’t have internet access even if the cellular data is turned on, try the lined up solutions below.

First solution: Restart (soft reset) your iPhone XS.

A highly recommended solution to various phone issues including network errors such as mobile data issues is a soft reset.

  2. When the Slide to Power Off command appears, release the buttons.
  3. Then drag the power off slider to the right to turn off your phone.

  1. From the Home screen, go to Settings.
  2. Scroll down to and select Cellular.
  3. If your Cellular Data switch is enabled, tap the switch to turn it off for a few seconds to refresh the cellular data functions then toggle the Cellular Data switch again to turn the feature back on.

Another way to refresh cellular data services on your iPhone XS is through the Airplane Mode trick. It works by toggling the Airplane Mode switch on and then off again.

  4. While it is on, reboot (soft reset) your iPhone XS.
  5. Then head back to Settings->Airplane Mode menu and toggle the switch to turn the feature off again.

You can also launch the Control Center on your phone to manage the Airplane Mode feature. Simply swipe down from the upper-right corner of your phone screen, and then tap the Airplane Mode icon to turn it on and off.

Turning Airplane mode on disables your phone’s wireless radios and associated functions. And turning it off, re-enables wireless features of your phone. So it’s like a quick restart on your iPhone’s wireless system including mobile data.

Wait for your iPhone to re-establish network connections and then allow it to reconnect to Cellular Data network. See if that solves the problem.

Network-related issues including mobile data errors can also be remedied by updating carrier settings on your iPhone. Most carrier updates are automatically imposed while other optional updates needed to be manually downloaded and installed. These updates are necessary as they keep your phone’s network services optimal and free from major issues. To get these updates installed, your device must have an internet connection. With that said, you need to connect your iPhone to a Wi-Fi network.

Once your phone is already connected to a wireless Internet, follow these steps to check for and install carrier settings update on your phone:

  1. From the Home screen, go to Settings.
  2. Select General.
  3. Tap About.

On the carrier section, you should see a notification regarding new carrier updates. If an update is available, just follow the onscreen prompts to update carrier settings on your device. Then restart your phone when the update is completely installed.
