Is your Samsung Galaxy S3 not receiving calls similar to the problem which was sent to us via The Droid Guy Mailbag, which reads, “My Samsung Galaxy S3 is not receiving calls. I get everything else but it does not even show that I received a call. I do get voice mail and text messages though. I turned it off and took the battery out but the problem is still there. Please help.”
How to Troubleshoot a Galaxy S3 Not Receiving Calls
The common causes of this type of problem may lie in the SIM card or the network. First, try to remove the SIM card and reinsert it to see whether it solves the problem. Check also if inserting another SIM card will help fix the issue. We recommend using a SIM card that runs on your carrier’s network and another that runs on another carrier’s network (provided that your phone is not locked to a specific carrier).
Replace your SIM card if you find that it is the one causing the problem or contact your network if using another SIM card seems to solve the issue.
Other Fixes to a Galaxy S3 Not Receiving Calls
It should be noted that upon looking at the forum of AT&T, some subscribers complained that they only got the problem when they updated their firmware to the 4.3 version.
Contributors in the forum suggested the following solutions that might possibly fix the problem:
1. Disable LTE
While the phone is powered on, remove its back cover and eject the SIM card.
The phone will prompt a restart once it detects the absence of the SIM card, so simply restart it.
Once the device is powered on, dial *#2263#.
Choose WCDMA and WCDMA All.
Put back the SIM card to its slot.
Reboot the Galaxy S3.
2. Run Device on 3G and Add New APN
This solution has been accepted by the forum but the contributor noted that dropped calls still persist, although the rate is much lower after performing the following steps:
Download 4G Toggle in Google Play store.
Switch from 4G to 3G.
Alternatively, you can use this method if you do not want to use the recommended app or the problem is not fixed after using it:
Go to Settings.
Select More Settings.
Choose Mobile Networks.
Proceed to Access Point Names.
Enter a new APN by naming it according to your preference and it should be defined as wap.cingular.
