Preparations: Check 5G on iPhone

Before you start to fix 5G connectivity on your iPhone, there are some things you need to pay attention to:

Part 1. Ensure Your iPhone Support 5G and Turn it on

Not all early iPhone models support 5G networks. Only the iPhone 12 and later versions have 5G capabilities. If you think it's necessary and the 4G network is no longer sufficient for your needs, you can consider switching to a new iPhone that supports 5G.

Part 3. Make Sure Your Carrier Supports 5G

Also, make sure your carrier supports 5G communication systems. Since 5G is still a relatively new program, not all carrier providers are able to implement it yet.
