But, before we jump right into the list of solutions to fix 5g connectivity issues on iPhone 15 Pro models, let’s talk about possible reasons behind it. 

Why 5G isn’t working on iPhone 15

There are plenty of reasons why 5G is not showing up on iPhone 15 Pro models. We have listed them below for your better understanding, keep reading. 

1. 1. If your iPhone 15 is not showing 5G, your NSP (Network Service Provider) doesn’t support 5G. You need to check with them if the 5G connectivity issues persist. It’s likely that it’s down temporarily for maintenance or updates.
   2. You may not have enabled 5G on your iPhone 15
   3. Poor 5G network coverage in your area
   4. Another reason why you can’t use 5G on iPhone 15 is due to an inactive 5G cellular plan
   5. Corrupted network settings
   6. Use of SIM cards without 5G support (iPhones sold US still support physical SIM)
   7. Occasional network glitch 
   8. Outdated carrier settings
   9. Software bugs

The above-listed reasons are usually the real culprit behind any kind of 5G issues on the iPhone 15 series. Now that you are aware of why 5G is not showing on your iPhone, it’s time to jump to the solutions. 

In the next section, you’ll find the 14 most effective solutions to resolve 5G issues on iPhone 15, iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max.

Let’s not waste further time and jump right into the list. 

Top 14 Ways to Fix 5G not working on iPhone 15, 15 Plus, 15 Pro, and 15 Pro Max

All the methods listed below have been tested by our teams internally and have fixed 5G issues on the iPhone 15 series. In addition, thousands of iPhone users have suggested similar solutions after testing, so, it is safe to say that all of them are somewhat useful. Make sure to try all of them until the issue is resolved.  

Method 1: Ensure your NSP supports 5G

Before you jump on to different troubleshooting methods to fix iPhone 15 Pro 5G not working issues, we recommend checking whether your network carrier supports 5G or not. If you can’t use 5G on iPhone 15 Plus and iPhone 15 Pro models, the first thing you should do is contact your network service provider (NSP) and check if it supports 5G networks. If you come to know that your NSP doesn’t offer 5G support just yet (which shouldn’t be the case), it’s a wise move to port your number to a 5G-supporting carrier like Verizon, AT&T, etc. Here’s an updated list of all the network carriers that support 5G.  While your NSP needs to support 5G services, the poor 5G network coverage in your area is equally responsible for 5G connectivity issues on the iPhone 15 series. Currently, the top three network carriers in the US have better and wider 5G coverage, while others have relatively less coverage. So, if you are using carriers with low coverage such as UScellular, Mint Mobile, Visible Wireless, or Boost Mobile, you might experience 5G issues on your iPhone 15 Plus. 

Therefore, it is always we always recommend choosing popular network carriers like AT&T, Verizon, T-Mobile, etc. All of them have better 5G coverage across the United States and have been very responsive whenever a network issue escalates. That said, users on these carriers have also reported 5G issues on the iPhone 15 series. 

All that said, we can say that if your carrier doesn’t support 5G or has a less 5G coverage area, there are high chance that you will face 5G issues on your iPhone 15 Pro and 15 Pro Max. That said, choosing a reliable carrier can be a game-changer for you.

On the flip side, if things look all right from the NSPs end, we recommend you try out the listed ways that can fix Verizon 5G not working on iPhone 15.

Method  2: Restart your iPhone

Are you wondering why is 5G not working on T-Mobile, AT&T, and Verizon? Generally, the 5G not showing up the issue on iPhone 15 is caused by conflicted network settings or poor 5G signals in your area. We’ve already addressed the latter but, it is very likely that some bug or glitch could be behind the 5G not working problem on iPhone 15 Pro and iPhone 15 Pro Max. So, to fix this you just have to do a simple reboot. Yes, you read that right. Restarting your iPhone is a quick fix that can resolve several network issues on your iPhone 15 series. This quick hack is equally handy in fixing iPhone 15 Wi-Fi not working problems and more. 

Performing a quick restart refreshes the system and starts it from scratch. This can be effective in dealing with faulty network settings or glitches that could be triggering iPhone 15 Pro 5G connectivity issues.  

If you just shifted to an iPhone or don’t know how to restart your iPhone 15 series, we have mentioned step-by-step instructions below:

Step 1: First, press and hold the Volume Up/Volume Down key and the Side button simultaneously,

Step 2: Next, swipe the slider left to right to turn off your iPhone, 

Step 3: Wait for a minute, then press and hold the Side button until you see the Apple logo.

Method 3: Check your SIM 

Have you purchased your iPhone 15 via your network carrier or with Apple including carrier activation? If yes, you shouldn’t face any network issues including 5G not working on iPhone 15 series. However, things can go South if you have bought a SIM-free variant. You must ensure that the existing SIM has been upgraded by your carrier before you insert it into your iPhone. To ensure this you must get in touch with your carrier support and confirm whether the SIM has been upgraded to 5G or not. If the upgrade hasn’t been done yet, make sure to do that in the first place. 

It might also be possible that your NSP (Network Service Provider) might replace your old SIM with a new 5G SIM with the same number to enable 5G usage on iPhone 15 Pro models. Therefore, if 5G is not working on your brand-new iPhone 15 series, you must upgrade to a new 5G SIM or upgrade to one with 4G support.

Note: Since all the iPhone 15 models (in the US) use eSIM and not a physical SIM, you’ll have to convert your physical SIM to eSIM first and then upgrade it to 5G.

Method 4: Check for an active 5G cellular plan

After you have ensured that your network provider and SIM card support 5G, it’s important to check whether you have a relevant 5G cellular plan. It might be possible that your SIM might be running on a 4G plan as a result you are facing an iPhone 15 Pro Max 5G not working problem. As far as popular carriers like Verizon and AT&T are concerned, their respective users might have to change or upgrade their old cellular plan with one that includes 5G connectivity. Therefore, if you can’t use 5G on the iPhone 15 Plus or facing 5G not working issues on the iPhone 15 Pro, make sure to verify with your NSP that you have an active 5G plan with calling, texting, and mobile data facilities. 

As an iPhone user, there is another thing that you need to take care of when 5G is not working on the iPhone 15 series. Remember, all cellular plans come with a limit and expiry, so you have to use the plan accordingly. Normally, cellular data plans have a daily data limit. So if you have enabled higher data usage tasks like auto iCloud backups or have been video-calling and binge-watching high-quality videos on mobile data, the limit will be exhausted soon. As a result, you can’t use 5G for a fast browsing experience.

Method 5: Double-check if you have enabled 5G on your iPhone

If you have ensured that your network carrier and SIM card support 5G, and you are living in an area listed under the 5G coverage map, you should see a 5G, 5G, 5G+, or 5G(UW) icon in the status bar. If you can see any of these on the status bar of your iPhone, it is safe to say that there are no 5G issues on your iPhone 15 Plus. However, there can be instances when your iPhone 15 won’t show 5G icons, as a result, you can’t use 5G.  While it may sound silly, this could happen when you or your kid mistakenly/unknowingly disable 5G on your iPhone 15. In such a situation, you will face issues where 5G won’t on iPhone 15 Pro. 

So, to avoid 5G issues on the iPhone 15 series, you need to ensure that you’ve enabled 5G. We have mentioned clear instructions below on how to do it, keep reading.

Step 1: Open Settings,

Step 2: Tap Cellular,

Step 3: Tap Cellular Data Options,

Step 4: Then, tap Voice and Data,

Step 5: If you see 5G already enabled, don’t do anything, if not, make sure to switch back to 5G Auto. 

It is worth mentioning that 5G Auto is selected on your iPhone, which means your iPhone will use 5G for every task where speed will matter. This might include downloading large files, video calling, binge-watching, etc. However, in Auto mode, your iPhone will switch back to LTE for several other tasks such as background updates, etc. So, if you want to experience blazing fast 5G speed for almost everything on your iPhone, we recommend you choose the ‘5G ON’ option in Step #5 mentioned above. 

If enabling 5G fixed iPhone 15 5G not working issues, congratulations. If you are among some unlucky users who are experiencing 5G connection issues on iPhone 15 Plus while roaming, don’t forget to try the next method.

Method 6: Have you enabled roaming on your iPhone 15?

Are you having 5G issues on your iPhone 15 especially when you are roaming (traveling outside your telecom circle)? If yes, make sure you’ve enabled roaming. It is worth knowing that the roaming feature allows you to use mobile data, make calls, and send texts when you’re outside your network operator’s circle. Therefore, if you want to use 5G while you are vacationing with your family, you must enable the roaming on your iPhone 15 series. Otherwise, you can’t access 5G data and calling services on your iPhone.

Here’s how to enable roaming on your iPhone 15 series: 

Step 1: Open Settings, 

Step 2: Tap Cellular, Cellular Data, or Mobile Data,

Step 3: Then, tap Cellular Data Options,

Step 4: Toggle ON the switch beside Data Roaming, and you’re done. 

Once you’ve enabled data roaming, you should see the 5G icon on the status bar after you open the cellular data. On the contrary, if you can’t see the 5G icon on the iPhone 15 Pro even after enabling roaming, you should try other methods we have listed below.

Method 7: Are you using the iPhone 15 Series in Low Power Mode?

Are you annoyed by slow 5G speeds on iPhone 15 series and 5G connectivity issues with iPhone 15 Pro/ 15 Pro Max? We think you should check whether you’ve put your iPhone in low-power mode. If you are uninitiated, let me tell you that Low Power Mode aims at saving battery by restricting several battery-consuming features. The fact that 5G consumes a lot of battery as compared to LTE, the Low Power Mode will limit the 5G connectivity on iPhones. It is worth knowing that this feature disables 5G on iPhone 15 series when you are watching video. The only way to use 5G efficiently is to disable the low-power mode.

Note: Low power mode automatically gets disabled when your iPhone charges past 80 percent.

If you manually want to turn off Low Power Mode on your iPhone, make sure to follow the step-by-step instructions given below:

Step 1: Open Settings,

Step 2: Tap Battery,

Step 3: Lastly, toggle OFF the switch beside the Low Power Mode, and you are done. 

After you’ve disabled the low power mode, check whether you can access or get good 5G speed on your iPhone or not. If this method didn’t help fix the iPhone 15 Plus 5G not working problems, we suggest playing around the Airplane mode to see if it helps fix the 5G network issue on the iPhone 15 Pro and 15 Pro Max. 

You can also disable Low Power Mode from the Control center.

Method 10: Manually select a 5G network

Even though your iPhone can easily recognize the network provider through the SIM and automatically connect to a network, that’s not the case always.
