Have you tried resetting your mobile networks? Settings> "Reset networks". I would recommend continuing to work with your carrier if the issue persists.
I'm having the same issue. My T-mobile issued Note 9 had full bars in my house. Purchased the Unlocked Note 10+ and now I'm only getting 1 - 2 bars. I have also tried reseting my Network in the settings and it hasn't fixed the problem. A new phone should always be an improvement, not the opposite.
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 ?
I have completed multiple restarts, multiple factory resets, several sim cards, apn adjustments and carrier swaps with still the same issues on both preordered devices.
