How to fix Koolnee weak signal or lost network issue?

Toggle the almighty ‘airplane mode’

Airplane or flight mode is often hailed as a powerful tool to get out of any trouble related to the network and it counts cellular too. So, to practice it, you need to drag down the notification panel and simply tap on the airplane mode icon to enable it. Now, wait for a few seconds before disabling it and that’s all. Repeat the same several times and check if the weak signal or lost network issue is restored or not.

Switch between SIM cards

Many a time, it happens that if you have a dual SIM support and one of the SIM doesn’t have network at all or it is very weak, you can simply tap on the dedicated SIM switch button if any or press its equivalent button on the UI basically by dragging down the notification panel to reveal it. This toggling between the SIMs forces the system to search for an available network on the affected SIM card.

Reboot the smartphone

If you can’t do a flight mode toggle, you can at least reboot the phone. It will take less than a minute but it will ensure that any temporary software glitch occurred whilst you were using the phone is resolved which includes a potential weak signal or lost network issue as well. Thus, give a quick reboot to the device and verify if it works or not.

Verify for any physical/liquid damage to SIM or tray

Call your telecom carrier

Suffering weak signal or there’s no network at all or if it is poor enough to not allow calls or messages, it’s time to call your network operator aka telecom carrier depending upon which service you use i.e. from Verizon, Vodafone, Idea, T-Mobile, Sprint, etc. Since you cannot call them with your phone with a poor network, take help from someone using the same services as you to call the customer care representative and notify them about the issue. They will scrutinize the same from their end and provide resolution if any.

The automatic to manual & vice versa switcheroo

Your phone is equipped with all sorts of settings and features related to its networking functionality. If you think the network is poor or goes unavailable when traveling, etc, you can switch between the automatic and manual mode. To simplify it, the automatic mode is the default and instructs the system to automatically search for available network and register while the manual mode needs manual search and registration. The automatic mode is helpful when in cities, towns with strength-y networks but when you are talking about traveling or going to villages or far-off places, you need a manual mode for better network reception.

Tweak ‘Preferred Networks’

Another set of features that your phone supports is the ‘Preferred Networks’ section which essentially allows users to switch between 2G, 3G, and 4G. By default, the phone will search for networks in the highest band support such as 4G (in 4G-enabled devices). If the 4G network is not available at the moment, you can freely instruct the phone to search for 3G or even 2G network which enables calling and texting if not fastest internet access. You can set it via “Settings » Networks (SIM) » Preferred Networks » 4G/3G/2G (auto)”.

Update all the apps and the firmware

Well, you need to understand that outdated apps are often vulnerable to a smartphone as it attracts bugs, viruses, malware, ransomware, hacking attempts, data breaches or what not. This is why you need to update all the apps on the system including both third-party and pre-installed apps and then, do the same with the firmware such as Android Oreo 7.x, etc. If there’s no firmware update available, you can seek custom ROMs as well which are easy to find and install and often gets faster updates.
