iPhone or iPad Showing Carrier Code (41004)Instead of Network Name After iOS Update?

After recent iOS updates, many iPhone 16,13 users have noticed that their iPhone or iPad shows a numeric carrier code (like “41004”) instead of their usual network name on the status bar.

The issue started randomly for the iPhone users and is seen in one country. The issue seems to be only on iOS devices as the Android devices are showing correct network name.

What Is Happening?

Normally, the carrier name (e.g., Vodafone, AT&T, Zong, etc.) is displayed. However, after an update, it is being replaced with a code number. This issue seems to occur only on iOS devices, as the same SIM card shows the correct network name on Android phones.

✅ Possible Reasons

• A carrier settings update might have changed the displayed name to a numeric code.
• The issue could be from the carrier end or due to iOS update compatibility.
• It may happen when the carrier profile fails to update properly after the new iOS version is installed.
