As you may recall, Apple released its iOS 12.1.1 update earlier this month. Along with the published update, many users who installed the new update were left alone with the network issue.

Faced with a huge response from users over social media, Apple has not yet made a formal statement about the issue of iOS 12.1.2 connectivity.

More and more iPhone users are spitting on social networks. After upgrading their iPhones to iOS 12.1.2, they can’t connect to the network through cellular data. The problem is still quite serious, and the models involved are also diverse.

Specifically, the symptom is that although iPhone displays 4G LTE network, but can not open the webpage with Safari, some social network APP can not send messages.

How to fix Network issues with iOS 12.1.2 (Temporary)

Because this issue manifests itself when your iPhone with iOS 12.1.2 is connected to a carrier’s LTE network, limiting the device to use LTE for data but not voice should fix this for you.

1) Open the Settings app on your iPhone.

2) Tap Cellular or Mobile Data, depending on your language settings.

3) Be sure that the Cellular Data toggle has been switches to the ON position.

4) Tap Wi-Fi Calling, then disable the feature on this iPhone.

5) Go back, then choose Cellular Data Options from the list.

6) Tap Enable 4G, then choose the option labeled Data Only.

NOTE: You may need to restart your iPhone for the changes to take effect.

Doing so will force your iPhone onto 3G and older 4G networks. This should help resolve the issues in many cases but it may and probably won’t work for all the affected customers. After Apple issues a fix, remember to revisit the aforementioned settings and re-enable the Wi-Fi Calling feature and turn on Voice and Data for 4G networks.

For instance, you may be unable to make voice calls over Wi-Fi networks (if Wi-Fi Calling is enabled) and regular phone calls over a carrier’s cellular network will not use VoLTE, meaning phone calls will take a few seconds to connect and thy won’t sound as crisp as with VoLTE.

On the plus side, you’ll be able to use SMS/MMS messaging services without disruption, iMessage and all the apps that use cellular data will work perfectly and you will have no issues making or receiving phone calls (aside from lower audio quality). – IDB
