Apple’s i OS mobile operating system is less prone (though not immune) to malware and viruses, compared with other platforms, like Android.
Still, it’s always good to keep an eye out for anything that seems fishy, like misspellings in the update message.
Unfortunately, getting answers to these questions is much harder than it should be.
Unlike major operating system updates, there isn’t a lot of information or messaging about what carrier settings updates do, where they come from or how they impact your device.
You may also get a message in i Tunes the next time you connect your device to your computer via USB.
If you notice any network issues or problems using such features as voicemail, it’s a good idea to check that you haven’t missed a carrier settings update using the steps outlined above before contacting your provider.
Waiting to install an update, or just ignoring the alerts, probably won’t cause any major problems.
But depending on what’s being released with the update, the benefits could include more functionality, better data speeds or improved call quality.
Google and Microsoft also make carrier-related changes to their Android and Windows Phone devices, respectively, but they’re folded into a more general software or maintenance update.Let’s say you’ve been using an unlocked i Phone on AT&T’s network and decide to switch over to T-Mobile.Your i Phone will need to update its carrier settings so the device can work with the new provider.But this hasn’t been a huge issue with carrier settings updates.If there is a problem, Apple and the carriers would assuredly issue a fix. Some updates are mandatory, and the only option you’ll see when the prompt comes up on the screen is "OK." Other times, you’ll have the choice to proceed with the update or delay it by tapping the "Not Now" button.
