The mutual thread inwards all these reports is the same: users are unable to mail or have text messages (SMS/MMS). And land cellular information seems to last working without a hiccup inwards apps similar Safari together with amongst services similar iMessage, folks are having issues making or receiving cellphone calls over their carrier’s LTE network (Voice over LTE or VoLTE calls).

Here’s a temporary solution that has worked for me similar a charm.

How to ready SMS together with LTE issues amongst iOS 12.1.2

Because this number manifests itself when your iPhone amongst iOS 12.1.2 is connected to a carrier’s LTE network, limiting the device to usage LTE for information but non vocalisation should ready this for you.

1) Open the Settings app on your iPhone.

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

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

4) Tap Wi-Fi Calling, together with then disable the characteristic on this iPhone.

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

6) Tap Enable 4G, together with then pick out the pick labeled Data Only.

NOTE: You may withdraw to restart your iPhone for the changes to direct maintain effect.

Doing thence volition forcefulness your iPhone onto 3G together with older 4G networks. This should assistance resolve the issues inwards many cases but it may together with in all probability won’t piece of work for all the affected customers. After Apple issues a fix, recall to revisit the aforementioned settings together with re-enable the Wi-Fi Calling characteristic together with plow on Voice together with Data for 4G networks.

This is exactly a temporary solution together with every bit such isn’t perfect.

For instance, you lot may last unable to brand vocalisation calls over Wi-Fi networks (if Wi-Fi Calling is enabled) together with regular telephone calls over a carrier’s cellular network volition non usage VoLTE, pregnant telephone calls volition direct maintain a few seconds to connect together with thy won’t well every bit crisp every bit amongst VoLTE.

On the summation side, you’ll last able to usage SMS/MMS messaging services without disruption, iMessage together with all the apps that usage cellular information volition piece of work perfectly together with you lot volition direct maintain no issues making or receiving telephone calls (aside from lower well quality).

What’s Apple saying? Not much.

Apple back upwardly advises performing a amount backup, together with then reinstalling iOS but that doesn’t appear to help. I am genuinely 1 of the affected people. After spending countless hours this vacation flavor on the telephone amongst my carrier’s support, I was able to decease a confirmation from them that there’s indeed a work amongst the latest iOS 12.1.2 update that’s causing this.

For what it’s worth, I recall at around signal after updating to iOS 12.1.2 seeing a message on my iPhone informing me that novel carriers settings are available, which I direct maintain installed.

I’m unsure if my carrier (T-Mobile) is only blaming Apple for this or if the carrier settings update that I direct maintain installed could last the culprit, but online reports appear to propose that this is a work amongst iOS 12.1.2 that volition last fixed inwards iOS 12.1.3, currently existence tested.

Your take

Either way, this is definitely non a variety of number that Apple customers should last dealing amongst during the festive season. Here’s to hoping that they free a ready for these annoying cellular woes sooner than later on together with restore basic smartphone functionality.

Have you lot experienced LTE calling or SMS problems after installing iOS 12.1.2?
