How To Fix iPhone 15 Pro Max Cellular Service Issues?

A reliable cellular connection is necessary for getting the most out of your iPhone 15 Pro Max. Whether you're streaming music, making calls, or browsing the web, weak signal strength can significantly hinder your experience.

You can explore several solutions to get your cellular service back on track. In this article, we'll break down the common culprits behind these cellular problems, guide you through troubleshooting steps, and explore alternative solutions to keep you connected.

Cellular service relies on a network of towers to transmit and receive signals. Sometimes, a weak connection might not necessarily be your phone's fault. However, let's clear some common misconceptions that can lead you down the wrong troubleshooting path.

• Dropped calls or slow data speeds aren't always due to exceeding your data plan.

• Similarly, being indoors doesn't automatically mean a bad signal – certain building materials can weaken reception.

• Apple does not purposely slow down your network every time it releases a new iPhone. Your old phone could be slower due to a lack of system updates.

• Just because you have the latest iPhone 15 Pro Max doesn't guarantee a magically strong connection. Signal strength depends on your carrier's network infrastructure and your location.

• The number of signal strength bars on your phone isn't always a perfect indicator of data speeds. Congestion on the cellular network can lead to slow data speeds even with full signal bars.

To say the least, these issues are more likely caused by network congestion, weak signal strength in your area, or problems with your phone's hardware or software.

First, it’s important to identify the issue with your weak cellular service. Are you experiencing dropped calls, slow data speeds, or not receiving text messages?

If so, your phone may be switching between different towers too frequently.

To check for this issue, go to “Settings” and then “Cellular.” Ensure the option for “Automatic” network selection is turned off.

If slow data speeds are the problem, you can do a few self-service repairs, which we’ll elaborate on in this article.

In the meantime, we’ll show you how to use the iPhone 15 Pro Max built-in diagnostics as part of System Configuration. Diagnostics mode can be helpful for advanced troubleshooting of cellular service issues.

To turn this mode on:

1. Power Off: Hold down either the volume up or down button and the side button together until you see the "slide to power off" slider. Slide the slider and wait 30 seconds for your phone to turn off completely.

2. Hold Volume Buttons: Press and hold both the volume up and down buttons at the same time.

3. Plug in While Holding: While still holding both volume buttons, connect your iPhone to a power adapter (ideally 18 watts or higher) or a computer that's powered on and plugged in.
   
   

4. Release on Apple Logo: Let go of the volume buttons once you see the Apple logo appear on the screen.

This process can be a bit more advanced. Below, we'll focus on easier troubleshooting steps you can try yourself.

Over a hundred iPhone 15 Pro Max users have been experiencing cellular service issues since its release in Q3 of 2023—and counting. Apple has since introduced common fixes to this issue that you can do yourself. Let's dive into the 11 solutions below.

Outdated software can sometimes lead to connectivity problems. To check for software updates:

Head to Settings > General > Software Update 

A simple restart can often resolve temporary glitches. Briefly press the volume down and the side button to restart. For a force restart, quickly press and release the volume up button, then the volume down button, and finally, hold the side button until you see the Apple logo.

This wipes out your Wi-Fi passwords and Bluetooth connections, but it can also resolve cellular issues. To do this:

Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings

Carrier settings updates can optimize your phone's connection with your cellular provider's network. Simply:

Go to Settings > General > About. If an update is available, you'll see an option to update.

Ensure Cellular Data is turned on in Settings > Cellular . Also, double-check that Airplane Mode is disabled in the Control Center .
