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