No, the iPhone X does not support 5G. It was released in 2017, before Apple introduced 5G connectivity in its smartphones. The iPhone X only supports 4G LTE, which means it cannot connect to 5G networks through a software update or a SIM card change.
I remember when 5G started becoming popular, I thought maybe older iPhones would get it through an iOS update. After all, software updates add new features all the time. But later I found out that 5G isn't just software; it's hardware. If a phone doesn't have a built-in 5G modem, no update can magically enable it.
Why doesn't the iPhone X Support 5G?
The main reason is simple: hardware limitations.
For a smartphone to connect to a 5G network, it needs a dedicated 5G modem and compatible internal antennas.
The iPhone X was designed years before Apple adopted this technology, so it only includes hardware for:
-
4G LTE
-
3G
-
2G (where still available)
-
Wi-Fi
-
Bluetooth
-
NFC
Since the required 5G hardware isn't inside the device, software updates cannot add this capability.
What Features Does the iPhone X Still Support?
Even though it doesn't support 5G, the iPhone X remains a capable smartphone for many everyday tasks.
It still offers:
-
Fast 4G LTE connectivity.
-
Face ID.
-
OLED Super Retina display.
-
Wireless charging.
-
Apple Pay.
-
High-quality cameras.
-
iOS app support (subject to Apple's software support policy).
For users who mainly browse the web, stream videos, use social media, or make video calls, 4G LTE is still fast enough in most situations.
Which iPhone Models Support 5G?
Apple introduced 5G starting with the iPhone 12 series.
These models support 5G:
-
iPhone 12, 12 mini, 12 Pro, and 12 Pro Max.
-
iPhone 13 series.
-
iPhone SE (3rd generation).
-
iPhone 14 series.
-
iPhone 15 series.
-
All newer iPhones released after these models.
If 5G is important to you, you'll need one of these devices or a newer model.
Can You Upgrade the iPhone X to 5G?
Unfortunately, no.
You cannot:
-
Install a software update to enable 5G.
-
Replace the modem.
-
Add external hardware that permanently enables 5G.
The only way to use 5G is to purchase a compatible smartphone.
If you're happy with your iPhone X and your local 4G network performs well, there may not be an urgent need to upgrade.
Should You Upgrade?
That depends on how you use your phone.
You may consider upgrading if:
-
Your area has excellent 5G coverage.
-
You download large files frequently.
-
You stream high-resolution content regularly.
-
You want longer software support.
-
Your iPhone X battery or performance has declined.
However, if your phone still meets your daily needs, upgrading solely for 5G may not be necessary. Many users continue to have a smooth experience with 4G LTE.

The iPhone X was an innovative smartphone when it launched, but it wasn't built with 5G hardware. As a result, it cannot access 5G networks, regardless of software updates or carrier changes. If fast 5G connectivity is one of your priorities, upgrading to an iPhone 12 or a newer model is the only practical solution. Otherwise, if your iPhone X still performs well for your everyday tasks, its 4G LTE connectivity remains perfectly usable for most users.

Frequently Asked Questions (FAQs)
1. Can the iPhone X connect to a 5G SIM card?
Yes, you can insert a 5G-enabled SIM card into an iPhone X, but the phone will only connect to 4G LTE because it doesn't have 5G hardware.
2. Which was the first iPhone to support 5G?
The iPhone 12 series, launched in 2020, was Apple's first lineup to include built-in 5G support.
3. Is 4G LTE still good enough in 2026?
For most users, yes. 4G LTE is still fast enough for web browsing, video streaming, social media, video calls, and online gaming in many areas.
4. Can Apple enable 5G on the iPhone X through an iOS update?
No. 5G requires a dedicated modem and compatible antennas, so it cannot be added through a software update.
5. Should I upgrade my iPhone X just for 5G?
It depends on your needs. If your iPhone X still performs well, and you're satisfied with its speed, upgrading solely for 5G may not be necessary. However, if you want faster connectivity, better performance, improved cameras, and longer software support, upgrading to a newer iPhone is worth considering.
