Top Ways to Fix iPhone 5G Not Working (iPhone 12/13/14/15)

Why is My 5G Not Working on My iPhone?

Have you ever experienced issues with iPhone 5G not working? Although 5G lets you perform tasks at blazing speeds, it doesn't always work as expected. There can be some reasons to cause it:

• Limited 5G coverage
• Incompatible carrier or plan
• Incorrect network settings
• Hardware or SIM card issues
• Software issues

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.

★Tips:

If you plan to change an old iPhone to a new iPhone which supports 5G, you can easily transfer data to new iPhone without data loss.

Part 2. Ensure the Area is Covered with 5G

Currently, 5G has not covered every corner. For example, in some remote rural areas, your phone doesn't have 5G. If you're not sure if your location supports 5G, the easiest way is to type in the place/country that Google has in 5G Maps+.

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.
