Mobile reception is very variable all over Shooters Hill. This map shows local 4G masts. So far I don't think 5G has been rolled out to this area.
If your mobile and network support Wi-Fi calling, turning it on will re-route calls through wifi if the mobile signal is weak.
The table below shows the reception reported by residents on the four physical networks (O2, EE, 3 and Vodafone) several years ago. Other networks piggyback on the four so you might get a better deal with the same reception by changing. However it's worth checking that any extra facilities that you use (like Wi-Fi calling) are available
