If you have an iPhone or iPad and you've recently installed a new version of your operating system, you might have noticed a pop-up message about carrier settings.
"Carrier Settings Update | New settings are available. Would you like to update them now?"
If you see the carrier settings update message on your iPhone or iPad, go ahead and tap "Update."
This update allows important work to happen in the background of your device, especially if you're planning on using aloSIM for prepaid eSIM data.
