Hey there hanubayan,

Connectivity is dependent on what kind of frequency your phone's transmitter is using. Other models may use different frequencies than your Galaxy S23 Ultra. Your device also has dual SIM support, and each SIM uses a separate transmitter that also have varying strengths (one SIM slot, for example, is reserved for 5G-capable SIM cards only.) 

Try switching your SIM card slots around and see if that improves the signal situation.
