My S23 will not connect to my service provider's network - Telstra via eSim. I have 40 gigabytes of data available at this time. 

I am in Northcliffe which is regional WA. Telstra covers the area as seen via their coverage map (the tower is literally next door to me). I am using my partner's Hotspot in order to connect to the internet to write this. She is also with Telstra but is using an iPhone 13 without issue and able to connect to 4G whilst I am unable to... My device connects to the 5G network when in metro areas, but outside of that I can not connect to the 4G or LTE network. There are no current network or service interruptions. I've had this issue consistently whilst being in Australia, but I've always been in a metro area until now due to work. 

I bought this S23 device in Canada in 2023, so the device is just over a year old and in superb condition. No drops, faults, scratches, physical alterations, etc. It still has manufacturing plastic adhered to the body. I have attached a screen saver and a case to the device. 

Here are my device's current software details and settings:

OneUI version 6.1 (recently updated Dec. 10)

Android version 14

My device's network mode is set to 5G/LTE/WCDMA/GSM. 

All 5 Access Point Names are listed:
Telstra Internet
HOS
IMS
Telstra Broadband
Telstra MMS 

Data roaming and VoLTE calls are enabled. 

40G of data available on the account. 

No physical SIM card in the device. Using an eSIM provided by Telstra.

I have attempted the following trouble shooting processes: 

Restarted device twice

Powered off device for 2 minutes and then I powered on the device 

Turned Airplane Mode on for more than 30 seconds then turned Airplane Mode off 

Ran device diagnostics with no reported issues.

Ran device optimization software with no reported issues and it reported great optimization in effect.

I am unsure what else to do besides factory resetting my device and unsure if that would even resolve this issue. 

Please advise...

A quick note, if you make a call via wi-fi calling turn off phone and data whilst making the call to force it to use the wi-fi calling software.

Huh thanks for the info that explains why my telstra phone has trouble connecting to NZ service when standing next to the tower.
And it kept reconnecting as though i had just arrived work for a bit and gone
