Sa sim card na problem yata yan. Pero try mo muna mga basic steps.
Reboot/restart your phone
Turn phone off, remove the simcard, reinsert, power on
Turn off mo yung isang sim kung dual sim ka
Baguhin mo yung preferred band ng affected sim (5g, 4g LTE, 3g)
Clear cache at mobile data ng Contacts app (make sure na backed up ang contacts mo either sa phone, samsung account, or google account)
Hindi step by step procedures yan mga yan ha, try one or more baka sakali masolve.

Hello Proy,

Thanks for letting us know your experience here about your beloved Samsung Galaxy A50 having issues with calls but can receive a text. I feel and understand why you are worried for a device that you've take care so much. If my device is facing similar experience, I will be bothered too.

Before you try out the below recommendations as to your solution, be sure to check if your device's software are updated with the latest version. Please check how to update your mobile device's software in the following order. 

Step 1. Go to Settings > Software update.

Step 2. Tap on Download and install

Step 3. Follow the on-screen instructions.


If you’re unable to make a call from your Galaxy device, it may be due to a faulty SIM card, an issue with your account or carrier, or a device setting. Check the guide below to find a solution.


Check your cell coverage and service status

You may experience call issues if you’re in an area with poor cell reception or if there is an issue with your account or carrier.

  • If you have poor cell reception, there will be a few to no network bars on the upper right corner of your screen. If that's the case, move to a spot with a stronger signal.
  • Verify that your account is in good standing.
  • Your device may be experiencing temporary issues with receiving signals from a cell tower. Try rebooting your device.


Check your device settings.


Device settings may be hindering your ability to make or receive calls. Check if Airplane mode is enabled or if your device is blocking calls from unknown or private numbers. 


Turn off Airplane mode.

Step 1. Open Settings and tap Connections.

Step 2. If Airplane mode is on, turn it off and check if your connection stabilizes.


Check if your device is blocking any unknown or private numbers.


Step 1.Open the Phone app and Tap More (Three dots in the upper right corner)

Step 2. Tap Settings

Step 3. Tap Block numbers.

Step 4. Turn off Block unknown/private numbers and check if you receive calls.


Reset Network Settings.

You can quickly reset your Samsung phone's network settings by opening the Settings app and then tapping General Management > Reset > Reset Network Settings > Reset Settings > Reset


Contact your carrier.

If you recently changed carriers but kept the same phone, you may need to contact the current carrier to reprogram your device. Contact your service provider for assistance.


In order to find out the root cause of the problem, you may submit an error report through the Samsung Members app as follows:


Step 1. Launch the Samsung Members app, and then tap the Support icon for more options.

Step 2. Scroll and select Error reports.

Step 3. Choose a category of your concern. Select "Call/Message".

Step 4.Choose the frequency of the issue you are experiencing. Enter issue details or attach a video or screenshot. Then press Send icons to complete the report.
