Unable to make or receive phone calls yet mobile data is fine.

Hello!

 

I have been experiencing issues with my S9+ making and receiving phone calls for the last few months. It's gotten to the point now where it's of little use beyond as a mobile tablet.  My mobile data functions just fine, perfectly even, yet I cannot make outoing nor receive incoming calls about 80% of the time.  My phone has also seemed to have some trouble switching towers as I often have to put it into airplane mode and take it out again to better my network connection.


These problems are experienced with a minimum of 2 bars signal:

Sometimes I will attempt to call out and it says it simply cannot connect. 
Sometimes I will attempt to call and it immediately goes to call failed.

Someone calls and it rings 4 times then goes to voice mail.
Someone calls and it goes straight to voice mail.

I can intermittently make or receive calls, but it seems totally random. I can make a phone call but then not receive one within minutes and vice versa.

 

  • I have reset Network settings.
  • I have reseated the sim.
  • I have turned it on and off both with a hard and soft reset.
  • I have cleared the Cache Partition.
  • I have not installed any new apps since my problems began.
  • Phone is totally up-to-date software wise

About the only thing I've found that I haven't tried is a factory reset.  Are there any other suggestions? Does this phone have a separate mobile data antenna from its telephone antenna?

 

We use Cricket Wireless for our cellphone service and my wife will have no issues on her iPhone 6 but I have issues on a Galaxy S9+ that's only a year old.

I recommend reaching out to your carrier regarding this issue.

@userW1w2JAznhq May I know what specific S9+ model are you using? the best way to solve this issue is through your wireless provider.

Hello! 

I have reached out to my carrier and they updated some settings and gave me a new sim card. 

 

The phone call issues appear to be fixed, although it's still too early to tell. I am still having signal issues, where I have to put it into airplane mode in order to switch towers and receive a better signal.
