But don’t get so worked up when suddenly you can’t send a text message or make a call. There are many solutions you can try to fix the lingering anomalies behind this issue.

In this article, we will discuss the causes of the iPhone 15 no service issue and how to fix it. The solutions are tested and easy to follow. Continue reading to learn more.

Top Reasons Why iPhone 15 is Losing Service

Network signals on our devices fluctuate sometimes. One minute it soars high; the next, it nosedives. Nothing is out of the ordinary at this point. But if the network signal stays low for a long time, something unusual is going on. It can be an indication of many things. So to help you figure out the early signs, below are the common causes of the iPhone 15 no signal issue.

Airplane Mode is currently enabled on your device.

It’s definitely a major concern when your iPhone 15 Pro flashes “No Service” notice randomly. But don’t judge prematurely. It’s still possible that nothing wrong is going on with your device. For instance, maybe you’ve just enabled the Airplane Mode by mistake. That happens most of the time.

There is a network outage or ongoing maintenance.

It’s a very rare event for network companies to tone down or cut off network reception. But it’s still a possibility, especially during calamities and other circumstances beyond anyone’s control. So when your iPhone 15 is losing service randomly, check first any announcement about network outages or anything similar.

Your current location is too far from the network’s serviceable area.

Is your iPhone 15 losing service while staying out of town? If so, it’s probably because your location is beyond the network’s coverage area. Don’t fret. It’s nothing serious. Your network connectivity will certainly return to its stable state once you get back to your residence.

Your iPhone 15 has misconfigured or outdated carrier settings.

Network companies regularly send carrier settings updates to ensure high-performing network connectivity for their consumers. If it happens that your iPhone 15 is losing signal, you may be using outdated carrier settings. Don’t worry. Everything will go back to normal as soon as you upgrade the settings to the latest version.

Your SIM card has already passed its expiry date.

Do SIM cards expire? The answer is yes, especially after they become inactive for a certain period of time. So if your iPhone 15 is mysteriously losing service, it’s possible your SIM has already passed its expiry date. Don’t worry. Just request for the SIM card replacement and have your account reactivated again.

Your iPhone 15 has hardware or system issues.

iPhone 15 and any other smartphones are composed of delicate hardware components. No matter how small or big, each of them has special functions. So glitches like the iPhone 15 no signal issue may arise if the device has sustained physical damage. The same thing goes if the operating system randomly misbehaves. The effect of such occurrences may restrict your smartphone from receiving decent network signals.
