Your screenshots show the battery charge declining by 7% in just 51 minutes – which is faster than normal. And 100% max capacity is higher than an original 11 Pro Max battery should be. I suspect that your battery is the original but doesn't really have 100% max capacity.


...So a weak, original battery would be the explanation for "No service". The battery cannot supply sufficient power to the iPhone's antenna to connect with cell tower signals. Have the aging, original battery replaced:

Faizanzainjana ~ iPhone 11 Pro Max was not sold after October 2020, so yours is at least 2½ years old and its original battery will not still have 100% maximum capacity.


Or perhaps that "100 % battery level" is its current charge and not its Maximum Capacity % here:


Settings > Battery > Battery Health & Charging


...Please clarify where you see that "100 % battery level".
