Updating my iphone
Unfortunately, the companies don’t make it easy to find out, if at all.It’s not like a third-party app update, which often offers a change log to show you what’s been added or fixed.
Apple’s i OS mobile operating system is less prone (though not immune) to malware and viruses, compared with other platforms, like Android.If all else fails, a Google search might lead to more specifics from an Apple or carrier-related user forum or site.But really, it would be nice if the parties involved spelled out the changes from the get-go, regardless of how big or small the update might be.Another instance where a carrier settings update may occur is when you swap out SIM cards.Let’s say you’ve been using an unlocked i Phone on AT&T’s network and decide to switch over to T-Mobile.The updates are largely used to add new features or enhance the performance.
This can include adding support for upgrades made to a carrier’s network or the rollout of new functionality like voice-over-LTE, which promises to deliver better-sounding voice calls. For example, a carrier update was issued after a bug was found on the Verizon i Phone 5s that was causing the phone to use cellular data while connected to a Wi-Fi network.
Since these updates tend to be smaller in size than major system upgrades, the update process should be faster, so you don’t have to be offline for very long.
The updates can include changes from Apple or any of its official carrier partners, like AT&T or Verizon, or it can be a combination of both.
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.
Waiting to install an update, or just ignoring the alerts, probably won’t cause any major problems.
The update may happen automatically once you insert the new SIM card.
