I would recommend reaching out to your carrier for assistance with their Network signal.
I'm having the same issue. I just switched from s10+ to note 10+ and the signal strength in TMobile is much worse. I'm going to call them today to see if there's anything that can be done about it.
They were both unlocked, bought direct from Samsung, FYI...
The New Samsung Galaxy Note 10+ appears to be having a signal reception issue &frequent dropped calls. Places where I have had great network service I have non places where I drove with out interruptions now I have many. There doesn't seem to be a fix insight.
What company do you have i just got mine today with att and I live in a town with about 10k people and haven't had an issue have you tried restarting the phone to connect to a closer tower ?
Yes, I have conducted restarts and even created a new APN. I have AT&T as well. My wife and I preordered our phones and we both have the same issues. We put our new sim back in out Note 8's and the signal is strong on that phone but extremely weak on the Samsung Galaxy Note 10+
I have AT&T too and preordered my note 10 plus from them. So far I havent had that issue or any issues on my new Note. My signal actually improved dramatically from the s10+ I had previously to now on my note 10 plus. My s10+ had horrible signal on it and I also live in town where there is normally excellent signal and strength. You may have to do a factory reset on the phone as well. But it should help.
I preordered mine directly through Samsung, so I am hoping that isn't the issue. I had conducted the factory reset when I was troubleshooting with the AT&T tech support and it didn't correct the issue, as well as creating a new APN, inserting the new sim card from the Note 10+ into the old phone (Note 8) which immediately had better reception upon restart.
