As per your query, we want to inform you that 5G network service may not be available depending on the network conditions of your mobile network service provider even though you are in the 5G service area.
Regarding this, the mobile network service provider will continuously improve the network quality of 5G service through gradual network coverage expansion going forward. And, the 5G devices use in conjunction with LTE and 5G networks and support the high-speed processing of large data, which may result in increased battery consumption and higher heat generation compared to LTE devices under the same conditions.
Also, when you use applications that require more power for extended periods, the device may heat up due to increased battery consumption as well. If the 5G device heats up to a specific temperature during use, the algorithm to prevent the device’s overheating operates, and accordingly, the maximum performance of the device may be limited and the network signal changes to a 4G network.
This is a normal operating condition to assure continuous device performance.
In this case, please wait for the device to get cool down for a while and then use the device again. If the 5G device gets cooled down to a specific temperature, the device will connect to the 5G network again.
I am disappointed by the apparent lack of comprehension demonstrated by customer support. Please review the submitted post again and understand the issue.
