Iv just came across this in the developer settings
By default network it's set as NSA mode non stand alone, I have switched to SA + NSA.
I do not no if this will have an effect on battery or not.
(I think it might)
NSA relies on the 4G network facilities to provide more speed and higher data bandwidth. A 5G-enabled smartphone will connect to 5G or 4G network depending on conditions.
( standalone ) SA is the true 5G network, where the 5G network has its dedicated 5G facilities to provide enormous speed improvements and minimal network latency (delay). The 5G SA network is independent of the 4G network.
Will obviously only work if your in a 5G area, but I think I see a difference in browser speeds and the full web pages loads up much faster.
Test for yourself.
Switched both options and tried network speed test got no difference. Dubai 5G network

Maybe I'm just seeing things lol, it's ment to take full advantage of the 5g speeds, maybe it doesn't work yet I don't know
Hope someone can give me advice. I have 5g in my house, my wife uses an IPHONE 12 promax and it can detect 5G but my device cant. can anyone help me please?
I'd like to up this too. I bought a Korean single sim phone with band n78 but it cannot detect 5g while my wife's IPhone 12 can. Any advice? Tried doing the quickshortcut app technique accessing the 5g signal manually but it won't select it for some reason
Check your SIM card or contact your carrier for help.
hi! Globe uses 5G NR/NSA n78 Band, which the korean varian SM-N986N supports.
Globe also provided information for foreign visitors who would like to hook to their infrastructure while visiting Ph. (see link below. don't mind the partner carrier)
5G Technology for Mobile - Globe
5G technology is the next generation of wireless internet connectivity that offers faster speed and more reliable internet connection than ever before.
www.globe.com.ph
if SM-N986N can't see the 5G network while other locally bought phones can, chances are 5G NR/NSA n78 band isn't available in your area and other phones hook through other 5G bands, or your sim card does not support 5G services.
i wasn't able to verify this when I went back to Ph, since my current provider's partner network is Smart
I'm constantly having to "reset network connections" on my new tmo s21. When I dial a # it rings 1-2x then silence while the call counter shows connected. Only way to fix the issue to reset the network.
Any solutions?
Been happening for the past month or so on T-Mobile for me, plus the network speed is ridiculously low, but ONLY on the S21. Moving my SIM to my Pixel 4a 5G, iPhone 12 Pro or Oneplus 9 Pro get normal speeds. Seeing about 300mb/s on those, and MAYBE 75mb/s on the S21. It's also not a fault model, because I have a T-Mobile branded S21 and an unlocked one as well. Both S21s have awful speeds.
Hello, so my Oneplus 8 5G show me the 5G icon even when it's just on LTE but the LTE tower also support 5G nsa. I find that pretty annoying that the device is lying about the connectivity.
Anyway to do so? I don't mind solutions that need root. Thanks
History:
Recently purchased a S23 Ultra (SM-S918U1) from Samsung USA. Downloaded and flashed the appropriate software for Samsung Canada (SM-S918W) using Patched Odin (3.14.1_3B). CSC, as expected, now reads TLS/TLS,TLS/XAA.
Network mode is set to 5G/LTE/WCDMA/GSM.
Problem:
I have strong signal in my area, 5G, but during phone calls, my signal drops from 5G to 3G (WCDMA) as opposed to the expected LTE+/LTE (4G or 4G+ for anyone outside of North America).
I have changed to a new SIM card and am able to reproduce the issue on my S22 Ultra.
I'm beginning to think it is a carrier issue, Telus, and have escalated to appropriate support tier for a callback.
Is anything else I should be looking for in-between? Specific flashing techniques or tools?
Thanks!
if you dont have VoLTE enabled then your signal goes to 3g during phone calls, its how the network works.

I greatly appreciate your help! I knew it would be something simple.
Enabling VoLTE is no longer available with this Canadian CSC (Telus/TLS).
I tested two devices; my S22 Ultra and Z Flip 4; the Z Flip 4 was purchased directly from Telus Canada, while the S22 Ultra was purchased from Samsung USA.
Following a factory reset and reboot, the Z Flip 4 automatically registers for IMS/VoLTE.
The same cannot be said for the S22 Ultra when running TLS. I see an option to enable 'VoLTE' if I switch back to XAA from XAC, but it doesn't do anything.
It appears the carrier may blacklist non-Telus purchased devices based on specific criteria (e.g., IMEI, serial number, etc).
This was not the case before 2021.
It is a carrier issue. Bell/Telus blocking VoLTE and WiFi Calling on non-Canadian devices that are not sold by Bell/Telus. If you put a Rogers SIM in your device, everything will work because Rogers is not limiting devices by IMEI and model number where Bell/Telus are!
File a CCTS complaint. The more they get. The hope that something will be done about it. They will also block your device from roaming on to US carriers and block 911 access as well. I get a text every month from Telus saying, "
TELUS Message: Hi J********, as you may be aware, carriers in the U.S. stopped supporting mobile devices on 3G networks.
You’re currently using a 3G phone that connects to 3G networks and the next time you roam in the U.S., you will no longer be able to use data, text or make phone calls - including 911.
To stay connected in the U.S., you need to replace your phone with an LTE or 5G capable phone.

I purchased mine from T-Mobile USA and use it with my T-Mobile SIM and Telus eSIM. I am on the U1 firmware.
Just call the Telus, telling them you brought a S23u from Samsung Canada. The model is S23 Ultra or SM-S918W. They will "apply the IMS registration profile" to enable the VoLTE and WifiCalling. That's how I did on my S918B. You don't need to change the CSC at all.
Thank you all for your excellent responses. I appreciate your help.
Telus' advanced support confirmed that non-Canadian Samsung devices are being blocked
Telus requests IMEIs from Samsung and registers IMS (VoLTE/WiFi Calling) if it matches the corresponding devices.
Google and Apple are the only exceptions. These criteria do not apply to them.
The next stop for me is the CRTC. If this concerns you as a resident of Canada, more information can be found here:

Telephone service problems can be resolved by making a complaint to the phone company, CCTS or CRTC.

This is actually what I was planning to do but before I could ask, they, the Telus Rep., had already identified it as non-Telus device.

CRTC won't do anything, neither will CCTS. They claim networks can do this for the "safety" of their network. Only Rogers allows US devices to use VoLTE for some reason.
I went through this last year.

Won't last sorry. If your IMEI isn't on the whitelist it will be eventually kicked off the profile.
