  1. New phone cannot hold a network that older phones have no issues with in the same household, looks like Samsung missed the basic – forgot that you need a signal to make a call!@

    1. Totally correct. Shelling out close to 1.5 lacs for a PHONE which has lower signal than a 8000 samsung phone

  2. Yikes! My new 23 Ultra can’t connect to the Internet. The Note 20 it’s replacing and my desktop are connected.

    I tried the tips. None have worked.

    I see lots of others have posted the same problem several place but no answer as of 5/2/23.

    Sadly, I’m going to have to return it to Amazon if no luck. Sure hope you’ve got a fix.

    Windows 11
    AX-6000 Router
    500+ Mbps+ download

  3. Shocking to say the least!

    So much worse than the note 10 a phone ten years older than this. Absolute rubbish and I will state that on every possible platform

  4. Wow same here.. I have tried my sim card in a oneplus 8 pro.. No issues… Huawei mate 20 pro.. Both old phones. And in menu selected signal strength.. Result in same location.. S23 ultra dbn – 105… Poor.. Oneplus – 80 miles better. And Huawei mate 20 pro – 82 again not amazing but the difference between making a call and not being able to… I absolute hate my s23 ultra.. The reception is poor just about everywhere I got.. I work in IT.. Done everything that samsung support suggest and it’s rubbish..

    1. I’ve had a persistent issue with my S23 Ultra phone regarding mobile data connectivity. When I stop using Wi-Fi and leave home, the phone doesn’t automatically connect to mobile data (LTE/4G). To resolve it, I need to restart the phone or toggle airplane mode on and off. These temporary actions don’t provide a permanent solution, and the problem persists even with a new SIM card and in different locations in my city where the signal is generally strong and stable.

  5. Switching back to apple the first chance I get, entirely. I can’t leave the house because then I’ll have no fkn signal. Even if it says I do.
