Hello there! The iPhone is highly regarded for its overall quality, but it's not without flaws. One annoying issue we might encounter is signal loss. The phenomenon of signal loss on the iPhone 5S, as well as other devices like iPhone X, iPhone 8, 8 Plus, 7, 7 Plus, 6s, 6s Plus, 6, 6 Plus, 5s, 5, 4s, is common and not solely due to network issues. Your iPhone may experience intermittent signal loss and instability, regardless of the location, unlike other devices. Here are the causes of signal loss on iPhone 5S:
- The BASEBAND, the part managing the phone's signal, may be facing issues due to strong usage or manufacturing defects.
- The integrated antenna for signal transmission and reception on iPhone 5S may have been damaged due to external impacts or manufacturing defects.
- The IC (Integrated Circuit) of the device is not functioning stably.
- Accidentally activating airplane mode leaves you unable to make calls or send texts.
- Installing too many apps causing conflicts is also a culprit for signal loss.
- Your SIM card may have circuit issues.
- Faulty Jailbreak can lead to signal loss.
1. Restart your iPhone.
Restarting your iPhone, while a simple method, is sometimes the most effective, bringing the device back to normalcy and addressing minor issues like Wi-Fi connection problems, 3G signal loss, and network signal issues. If you've restarted your iPhone multiple times and the searching error persists, consider applying more advanced measures shared by Mytour below.
2. Clean the SIM card slot
If the searching error occurs frequently but then resolves itself, the cause may be the SIM card. To be sure, remove the SIM, clean it, and test it in another phone. Then, reinstall it in your iPhone to check again.
3. Activate Airplane Mode
Enabling Airplane Mode on your device is the easiest way to resolve the no-signal issue on iPhone. In this mode, all network services like Wi-Fi, 3G, Bluetooth, etc., will be turned off. To activate this mode, simply swipe up from the bottom of the screen to access the Control Center, then tap the airplane icon in the top-left corner. After switching to Airplane Mode, wait a few minutes, then disable it using the same method.
4. Reset Network Settings
The iPhone's signal is related to the baseband, the foundational frequency band that helps in receiving signals from the network. If there's an issue with this part, the iPhone will lose network signal. You can read more about fixing iPhone baseband issues to understand this problem better. To reset network settings, access Settings > General > Reset > Reset Network Settings.
Additionally, readers can explore other methods such as:
- Try inserting your SIM into another phone to check if the issue is with the SIM card.
- Perform a Restore on the device and see if the issue persists. Find instructions on how to restore an iPhone here.
- Remove unnecessary apps and restart the iPhone to see if the issue persists.
To effectively address the issue, you need to pinpoint the exact cause of the problem related to BASEBAND, signal antenna, and internal hardware. For the best resolution, take your device to iPhone service centers for thorough examination, warranty, and repair.
