A carrier settings update is a small file from Apple and your network that tells your iPhone how to work with Jio. To install one, connect to Wi-Fi or mobile data, open Settings > General > About and wait a few seconds. If an update is available, a pop-up appears, and you tap Update.
These updates can bring network improvements such as better 5G, VoLTE and Wi-Fi Calling support on Jio. They are quick, free and much smaller than an iOS update. This guide explains what they do, how to install one, how to check your version and what to try if nothing appears.
- A carrier settings update adjusts how your iPhone works with Jio’s network, including calling, data and messaging settings.
- To check for one, go to Settings > General > About and wait for a pop-up.
- If no pop-up appears, your carrier settings are usually already current.
- Only accept updates shown by iOS itself, never profiles from websites or messages.
What Is a Carrier Settings Update?
Your iPhone stores a set of network settings for each mobile operator. Apple and the operator update these settings from time to time. When a new version is ready for Jio, your iPhone can download it as a carrier settings update.
According to Apple, these updates can cover network, calling, mobile data, messaging, personal hotspot and voicemail settings. They are separate from iOS updates, which change the whole operating system. A carrier settings update only touches the network-related settings for your SIM.
Most of the time, you do not need to do anything. Your iPhone shows a pop-up when an update is available. But if you dismissed it, changed your SIM or are missing a feature, it helps to check manually.
What It Can Change for Jio Users
Each update is different, and Apple does not always list the changes. For Jio users, carrier updates have been linked to features such as:
- 5G support and improvements on 5G-capable iPhones.
- VoLTE for HD voice calls over Jio 4G.
- Wi-Fi Calling, so you can make Jio calls over a Wi-Fi network.
- Personal hotspot and MMS settings.
- Network name and signal display in the status bar.
If a feature like Wi-Fi Calling or the 5G option is missing on your iPhone, an outdated carrier setting is one of the first things to rule out.
How to Install a Carrier Settings Update on iPhone
Follow these steps. Labels can differ slightly between iOS versions.
- Make sure your iPhone is connected to Wi-Fi or mobile data.
- Open Settings > General > About.
- Stay on the About screen for about 10 to 15 seconds.
- If a Carrier Settings Update pop-up appears, tap Update.
- Wait a few seconds for it to install.
- If new features do not appear right away, restart the iPhone.

If no pop-up appears, there is usually no new update for your SIM. You cannot force one, and you do not need to.
Carrier settings updates arrive through the iPhone’s own Settings. Never install a “network profile” or “5G profile” from a website, message or social media link. Such profiles can change your settings or track your activity. You can review installed profiles under Settings > General > VPN & Device Management.
How to Check Your Current Carrier Settings Version
You can see which carrier settings version your iPhone is using:
- Open Settings > General > About.
- Scroll to the section for your SIM. It may be labelled Physical SIM, eSIM or with your line’s name.
- Look at the Carrier or Network Provider line. It shows the network name with a version number next to it.
- Tap the line to see more detail, if your iOS version shows it.
The version number is mainly useful if you contact Jio or Apple support. You do not need to track it yourself.
Carrier settings update vs iOS update
| Feature | Carrier settings update | iOS update |
|---|---|---|
| What it changes | Network settings for your SIM | The whole operating system |
| Size | Very small | Large download |
| Where it appears | Pop-up, often on the About screen | Settings > General > Software Update |
| Restart needed | Usually not | Yes |
| Who provides it | Apple with your network | Apple |
When You Should Check for an Update
Check manually in these situations:
- You inserted a new Jio SIM or moved your SIM from another phone. Apple notes that a new SIM may need the new carrier’s settings.
- You converted to a Jio eSIM or switched lines on a dual SIM iPhone.
- You ported your number to Jio from another network.
- You just installed an iOS update. New iOS versions often include fresh carrier settings, but a separate update may follow.
- A feature is missing, such as the 5G option, VoLTE or Wi-Fi Calling.
If Jio 5G or Wi-Fi Calling is not showing, install the latest iOS from Settings > General > Software Update, then open the About screen. Doing both in order covers the two most common causes.
No Update Showing? What to Try
If you expect an update but nothing appears, work through these steps:
- Check that mobile data or Wi-Fi is working by opening a website.
- Restart your iPhone, then open General > About again.
- Install any pending iOS update.
- Remove and reinsert the physical SIM, if you use one.
- As a last step, use Reset Network Settings under Settings > General > Transfer or Reset iPhone > Reset. This removes saved Wi-Fi passwords.
If features are still missing, call Jio on 199 from your Jio number for queries. They can confirm whether your line is set up for features such as VoLTE and Wi-Fi Calling.

Frequently Asked Questions
Is a carrier settings update safe to install?
Yes, when it appears as a pop-up from your iPhone’s own Settings. It comes from Apple and your network. Only avoid profiles offered by websites or messages.
How often do carrier settings updates come out?
There is no fixed schedule. They are released when Apple and the operator have changes ready, and some also arrive bundled with iOS updates.
Will a carrier update delete my data?
No. It only changes network-related settings for your SIM. Your photos, apps and messages are not affected.
Can I undo a carrier settings update?
There is no option to roll one back. If something stops working after an update, restart the iPhone and contact Jio or Apple support.
Why does my iPhone show no update when I open About?

Wrapping Up
A carrier settings update is one of the simplest fixes for network features on an iPhone. Open Settings > General > About, accept any update that appears and keep iOS current. If 5G, VoLTE or Wi-Fi Calling still do not show on your Jio line, try the steps above before you contact support.
