Our reader sent us a screenshot of his Samsung S23 in service mode. He discovered that Singtel is not just using 5G NSA and 5G SA modes, but is also running a 5G SA 2CA mode. This combines the bandwidth of n1 (20 MHz) and n78 (100 MHz) to enhance coverage and speed.
Interestingly, the speed achieved with this configuration isn’t as impressive as those with a single n78 SA. This might be due to it being an experimental setup.
