How to Fix Cellular Data Not Working on iPhone XS Max: 9 Ways


1. Enable LTE in Cellular Option.

Long Term Evolution or LTE, in short, is a standard in modern cellular networks that help provide a larger capacity of bandwidth compared to the older version of cellular data technology. Network carriers have been using LTE which can also be written as 4G-LTE for a while now to deliver a faster internet service that makes the most out of 4G’s potential.

So it’s likely that the LTE feature was not enabled on your iPhone as you may have initially presumed it had nothing to with cellular data.

To enable LTE, simply go into your iPhone’s Settings app and then tap on Cellular. Next, select Cellular Data Options. Lastly, tap on Enable LTE then make sure the Enable LTE option is enabled for both Voice & Data.

One older iOS models, you can access the Enable LTE page by going into your Settings > Mobile Data and tap Enable LTE.

If you do not see the LTE option, then chances are it may appear written as 4G instead. If 4G doesn’t appear too, then you will want to get in touch with your wireless carrier and see if they indeed provide the 4G/LTE service (some wireless carriers don’t) and then request to upgrade your plan.





2. Remove and Re-insert the SIM Card.

The solution that worked to restore the cellular data capabilities for our own iPhone XS Max was to remove and then re-insert the SIM card. It’s likely that your iPhone may have suffered from a fall impact that could have resulted in a misalignment of your SIM card. To be sure, remove and re-insert your SIM card on your iPhone.

Here’s how you can do it:

  1. First and foremost, turn off your iPhone XS Max by tapping on the Settings, then General and then Shut Down.
  2. Then, insert the SIM removal tool, which came in with your iPhone XS Max, into the small hole on the right side of your device.
  3. After that, push it in slightly to eject the SIM card tray and remove it.

  1. Next, remove the SIM card from the tray and place it again with the metal chip facing downward.
  2. Now re-insert the SIM card tray into the iPhone slot and push it in towards the device until it clicks into place.
  3. Finally, turn back on your iPhone and enable your Cellular Data setting.

Now that you have made sure that your SIM card is securely in place, you will be able to connect to the internet using your cellular data network. Let us know down below whether this method works for you just like it did for us.



3. Refresh Cellular Data Connection.

There is a possibility that you may have a weak cellular signal where you are trying to connect. Sometimes your iPhone needs to lock in with the strongest signal in the area so it can sync with the cellular network. To help your iPhone do this, you need to refresh your cellular network connection.

You can do this by tapping on the Settings and then Cellular option. Tap on the Cellular Data option switch and give it a good 15 seconds and make sure you have a good cellular signal. Tap the switch again to enable it again.

4. Use Airplane Mode to Remove Connection Conflict.

One of the most effective ways to reset your cellular data connections is to turn on Airplane mode. By turning on Airplane mode and then turning it back off, you are essentially removing any conflicts that may have occurred with the connection with your wireless carrier over time.

Turning on Airplane mode does disable all your connections such as Bluetooth, Wi-Fi, and Cellular network all at the same time, which helps to remove any faults or bugs with these services so that you can start anew.

Here’s how you can turn on your Airplane mode (if you didn’t know how):

  1. First, make sure you are at the home screen of your iPhone XS Max.
  2. Next, bring up your Control Center then tap the Airplane Mode switch iPhone Stuck in Headphones Mode  to enable it.

  1. Give it around 5 minutes before you switch back to disable Airplane Mode.
  2. Finally, on the same screen, tap on Cellular and enable your cellular data network connection.



5. Update Network Carrier Settings.

It is known that wireless carriers constantly make changes to their network so they can deliver a good user experience to their clients. Some of these network upgrades require you to change the settings on your iPhone for it to work. This is not complicated because all you have to do is just hit the Update option when a carrier settings update is available.

To find out whether you have any new carrier settings update to be installed, here’s what you do:

  1. Go ahead and connect your iPhone to the internet using a Wi-Fi connection.
  2. Then tap the Settings on your iPhone XS Max, then General option, and then the About option.
  3. Now find the Carrier section and give it a few seconds to check for new updates.

If the above process does not work or you find that cellular update fails to be installed, then you may want to consider contacting your wireless carrier for more information. You have to make sure that the SIM card you are using is correctly configured by their technician so you can successfully connect to their network. We strongly advise that if the SIM card doesn’t work on your iPhone, then have them try it on a different phone. This process is essential to rule out any problems with your SIM card itself.

Having updated the cellular settings on your iPhone, you should be able to connect to the internet using cellular data with no issues.

Doing this helps to recover the device from any corrupted network settings that may have been caused by improper shutdown processes, unsafe networks, or unsuccessful updates.

By rebuilding the settings back to its default state, it will repair the device so that it starts afresh when connecting to network services such as your Wi-Fi and particularly your cellular data. Take note, however, that by resetting your iPhone’s network settings will erase any saved Wi-Fi passwords or custom configurations you may have set for your network (if you have any). It’s a good idea to record down your saved Wi-Fi passwords before going through with the below steps.

When you’re ready, here’s how you do it:
