Could Not Activate Cellular Data Network means you cannot be able to connect to 4G or 5G wireless networks if your iPhone displays the “Could Not Activate Cellular Data Network” warning. This mistake does not interfere with Wi-Fi or Bluetooth connections, but while you’re on the go, you require cellular data. Here’s how to resolve an iOS “Could Not Activate Cellular Data Network” problem.
Why is my iPhone displaying the message “Could Not Activate Cellular Data Network”?
When your iPhone displays the “Could Not Activate Cellular Data Network” error message, it implies that your phone is unable to connect to your phone company’s wireless data network. While you may still be able to make calls, the issue suggests you won’t be able to check email, browse the web, or use apps on 4G or 5G.
How Do You Turn On Your iPhone’s Cellular Network?
A variety of factors can cause this difficulty. We’ll go over them further down. Follow these procedures in this sequence to resolve your iPhone’s cellular data network problem.
Confirm it the airplane mode is turned off.
Airplane Mode disables all networking functions on your iPhone. Cellular data networks will be unavailable if you switch them on by accident. Switch off Airplane Mode to resolve this issue.
Restart your iPhone.
You’d be shocked how frequently merely restarting your iPhone will resolve issues. A restart clears your iPhone’s active memory (though no data is lost), where temporary issues can appear. A restart is unlikely to resolve the “Could Not Activate Cellular Data Network” problem, but it’s simple and quick, so it’s worth a go.
Turn on Cellular Data.
While Airplane Mode disables all networking, the iPhone allows you to disable network types individually. As a result, you may be unable to connect to cellular data networks because you have switched off cellular data. To resolve this, go to Settings > Cellular and toggle the Cellular Data slider to the on/green position.
If the slider was previously set to on/green, try moving it to off/white for a few seconds, then back to on/green. It may cause your connection to reset and resolve the error.
Remove and replace the SIM card.
The SIM Card in your iPhone allows it to connect to the data network of your phone carrier. You may have a problem with cellular data if it has a problem. To resolve this, remove and reinsert your iPhone’s SIM card. If this was the issue, you should have no trouble connecting to a cellular data network in seconds.
Carrier Settings should be updated.
Carrier Settings are personal settings on your iPhone that determine how it interacts with your phone company’s network. If your phone’s settings are outdated, this could explain the cellular data issue. However, a fast carrier settings update—connect to Wi-Fi; no restart required!—might fix it.
Upgrade the iPhone’s operating system.
Still no joy? It’s time to update your operating system. Each new iOS version includes bug fixes and new functionality. The cause of your issue may have been addressed in the most recent OS upgrade. First, you’ll need to discover a Wi-Fi network because you won’t be able to connect to a cellular network. After that, restart your iPhone and see if you’re back in business.
Reset Network Configuration.
Under the overall category of Network Options, your iPhone contains a plethora of tiny settings and preferences related to how it connects to networks. If one of these settings is corrupted, it may prevent you from accessing cellular data networks. Resetting your iPhone’s network settings will result in new locations and may solve the problem.
You will lose all saved networking settings and passwords if you do this. As a result, you’ll have to re-pair Bluetooth devices and enter Wi-Fi passwords.
Contact Your Telephone Company.
If nothing else has worked so far, contact your phone carrier. Maybe the problem isn’t with your phone, but with the phone company, and only they can help you.
Obtain Apple’s assistance.
If you haven’t fixed the problem yet, it’s likely more complex than you can tackle on your own. It is time to call in the professionals, whether the issue is hardware or software. You can visit Apple or schedule in-person support at your nearest Apple Store.
How do you move cellular data from an old iPhone to a new one?
During iPhone setup, iOS gives you a choice to transfer your cellular plan. First, tap Continue after selecting the numbers to be shared. Then, to complete the form, follow the onscreen instructions. After you’ve completed the setup, navigate to Settings > Cellular > Add Cellular Plan to transfer your cellular plan. When you activate your new iPhone’s cellular plan, the one on your previous smartphone is deactivated.
What does it signify when your cellular data roaming?
When you leave your carrier’s coverage area, your phone will continue to get cellular data. While local roaming is typically free, international roaming may incur additional charges. The amount you pay is specified by the carrier you use.
Why is mobile data so slow?
There are numerous causes for your phone’s cellular data to slow down. Carrier throttling is the most common. Many plans only provide a certain quantity of high-speed data each month. The carrier throttles your Internet speed when you approach that limit. Perhaps the network on which your phone is now connected (4G, 5G, etc.) is weaker in that location. Radio frequencies can also disrupt cellular data transmission.
