If your Android phone can't make or receive calls, read the suggestions below. Before doing anything on your device, ensure that your account is active and there are no issues with your carrier or outstanding bills.
What To Do when you Can't Make or Receive Phone Calls?
Let's start with the basics.
- Ensure you have an active mobile plan with your carrier and your signal is not weak (Reception).
- Check your contact blocked list. Try to place a call to different numbers.
- Check the Airplane mode. Sometimes, we accidentally enable the feature. Open Settings > Connections > Airplane mode. Toggle the switch button.
- Remove your SIM card and put it back. If you have another phone around, place your SIM card on it and try to make a phone call.
- Restart your phone.
Perhaps you accidentally enabled the Airplane mode on your phone, disabled WiFi, etc. Therefore, before we go further, do these quick troubleshoots.
- Make sure the Airplane mode is disabled. You can also toggle the Airplane mode on and off
- Toggle WiFi
- Toggle Mobile Data
Solution 1: Call Your Carrier
Phone call issues do not always come from the phone itself, the WiFi, or the SIM card. It may come from the provider you use. Perhaps, their system is down or is under maintenance.
Try to reach your carrier using another phone, email, live chat, etc.
Solution 2: Disable The Do Not Disturb
Do Not Disturb allows you to mute incoming calls, messages, and notifications. The point is to help you focus on what you are doing without being distracted by your phone. Check if you unintentionally enabled the feature.
To disable the Do Not Disturb, go to:
- Settings > Notifications> Do not disturb
- Toggle the button to turn off the feature.
Alternatively, you can do it through Quick settings by swiping the screen from the top. Tap the Do not disturb icon until it turns grey.
Solution 3: Turn off the Smart Call
When you activate the Smart Call feature on your Samsung Galaxy Phone, it will automatically block every number not listed on your contact. Before disabling it, make sure the numbers exist on your contact list.
Steps to turn off the Smart Call feature
- Launch the Phone app
- Tap the More option (three dots) and select Settings
- Tap the switch button next to the Call-ID and spam protection option until it turns green
While you are in the Settings, you can also investigate the Block number option. By tapping it, you will see the blocked list of blocked numbers, if any. Tap Delete to unblock the number.
Solution 4: Restart Your Phone
Press the Power button and hold it until the Power off screen appears and tap Restart.
Solution 5: Disable Call forwarding
Some people have more than one phone for different purposes. For instance, one phone is for business and another for personal use. If you have two Android devices and want to forward the call from a personal phone to a business phone, enabling the Call forwarding feature will help.
The idea of the Call forwarding feature is to redirect the incoming phone from one phone to another. To disable the Call forwarding feature, follow the steps.
- Tap the Phone app from the home screen
- Tap More (three dots)
- On the drop-down menu, choose Settings
- Scroll down to find the Supplementary Services option
- Tap Call forwarding
- Tap Always forward and choose Enable
While you are in the Supplementary Services screen, also investigate the call barring feature. Make sure this feature is not active. Otherwise, it will stop all incoming and outgoing calls.
From the Supplementary Services screen:
- Tap Call barring instead of Call forwarding.
- Then, tap Voice call and turn off the All incoming calls option.
Solution 6: Inspect Internet Connection
To make VoIP calls, you need an Internet connection. Ensure you have a stable WiFi network or cellular data on your phone.
- Toggle WiFi
- Switch to mobile data or try a different WiFi network if it is available
Solution 7: Reset Network Settings
If the caller tries to reach you via WiFi or cellular data, Reset network settings can solve the issue. To perform this method, open:
- Settings > General Management
- Reset > Reset network settings.
After that, you need to re-enter your WiFi password because the resetting process erases all the WiFi passwords you have entered before.
Solution 8: Inspect The Sim Card
The problem may not come from your phone but the SIM card or provider. Check if the signal is full or weak. Also, make sure you use an active SIM card. Check if your SIM Card is placed correctly.
Solution 9: Reset to Factory Settings
You may lose your data during the process. That is why you need to backup your phone before starting. First, go to Settings > General Management > Reset > Factory data reset.
