Calling is the most basic functionality that your phone possesses. It needs no mobile data or WiFi (unless you are talking about WiFi Calling) but all it needs is a cellular network and that’s all. Depending upon the network strength, you might either hear a crystal clear sound or voice will break. Turns out call getting disconnected automatically on your TCL 20B can happen both when making a call or during a call, if you called or received someone’s call. In both cases, it is exasperating which is why you are here to find a fix.
When our team was doing research on this topic, we found that there are some products that can help to improve network strength in your home. Did you hear about Signal Booster created by SureCall? We haven’t tested it yet but it looks like the product is currently very popular on Amazon with 3K+ ratings.

After digging through a bunch of guides and recommendations by experts and OEMs, here are a few ways to fix the call getting disconnected automatically on your TCL 20B.
Check for Network strength
Are calls getting disconnected automatically? Call drops? Inferior call quality or voice is breaking or it isn’t audible? All this can happen if the network strength in your TCL 20B is on the lower side. You can check the current network strength on the status bar on your phone. It can be found denoted either by a bunch of bars arranged in an ascending order or a right-angled triangle. It goes without saying, the more the merrier.
Check if it is just you or others too
You just saw that the network is okay (but not great) which should be enough to make and receive calls but you aren’t able to do it. Why? The best way to find the culprit is by zeroing the list of possible reasons. The first thing you need to do is to verify if the call connectivity issue that you are facing is just affecting you or everyone else using the same carrier.
The results are quite self-explanatory. If it is just you, there’s something wrong with your TCL 20B. But if it is everyone, it could be a carrier issue that should solve in some time.
Use Airplane Mode [ Call getting disconnected automatically on TCL 20B ]
One of the quickest ways to get rid of any network issue is to put your TCL 20B in airplane mode. It does put your TCL 20B in a no cellular network reception mode until it is engaged. But it has proven to work in many cases. No doubt it is one of the many troubleshooting methods that we have found to be useful and thus, mentioned here.
- Pull down the notification panel on your TCL 20B.
- Spot the “Airplane Mode” icon on the Quick Settings section and tap on it to engage it.
- Hold on for a few seconds and disengage it.
- Check whether you are able to make calls and receive them without any hassle or not.
Reboot your TCL 20B
Call it the mother of all fixes, rebooting your TCL 20B can work wonders. Since it puts the system to rest, it torches all the apps and processes that were running in the foreground and background and deallocates resources. Since you are rebooting the TCL 20B, software glitches will go down it allowing you to restore the phone’s ability to call and receive calls without any hassle.
- There’s no rocket science here. Press the power button for 3-4 seconds.
- Select “Reboot” or “Power Off” and wait for 1-2 minutes.
- Press the power button for 3-4 seconds and the phone should turn ON immediately.
Call Carrier to find the issue
If the call connectivity is a problem with your existing carrier, do give them a call and ask what’s wrong and what needs to be done. The representative should be able to zero in on the problem. Be it less network coverage in your locality or if there’s something wrong on your end such as if the network reception antenna is faulty or so on.
Clear Phone App Cache [ Call getting disconnected automatically on TCL 20B ]
Cache files are created and stored by the phone’s system in order to speed up certain processes such as opening certain apps and processes, accessing details that you would ask repeatedly, etc. However, cache files are often the source of many issues and seem like it is also behind calls getting disconnected automatically on your TCL 20B. Turns out it is easier to simply get rid of cache altogether. Here’s how it goes.
- Since the problem is with calling, find the Phone app or Truecaller, or any other app that you use for calling.
- Long-press on the icon to open a pop-up, select “App Info”.
- Go to its Storage and hit the “Clear Cache” button and that should do the trick.
Get a Mobile Signal Booster
Call it a signal booster or amplifier, it works. It essentially amplifies the signal coming from a tower that assists in better and healthier cellular reception. You should get it from Amazon or other avenues and set it up on your own. If not, call in someone who knows how to set it up.
Update the OS [ Call getting disconnected automatically on TCL 20B ]
Your TCL 20B uses Android OS. The software requires updates to keep it running and troubleshoot any glitches. That’s where updating the OS comes into play. Here’s how you can do it.
- Firstly, open Settings >> About Phone >> System >> Software Updates.
- You need to check whether there’s an update available or not.
- If yes, download and install it.
- If not, wait for an update to arrive in your TCL 20B. You can also go through a custom ROM such as Pixel Experience but that’s subjective.
Port to a different Carrier
Your current telecom carrier is working fine but there are network issues in your locality be it the office or at home, etc. If you happen to have issues with your current carrier, porting to a new one can fix the problem. It is a lot easier to retain the phone number and port from Vodafone to AT&T (for instance) or a combination of any other carrier that serves quality services in the area you live in.
Depending upon which country you live in, the porting method can differ, and thus, ask your existing carrier for details.

The technician can help diagnose the problem, find if it is a software or hardware issue, and troubleshoot it.

So it’s better to use this guide as a reference, repeat the methods and report the issue to a service center if nothing works.
