Mobility - BC Poor Reception

Anyone else finding Telus Mobility reception to be horrible in BC? Lower Mainland and Vancouver Island are a struggle (iPhone 15 Pro), frequently with 0-1 bars and no data connectivity. Will Telus ever invest in more cell towers?

My theory is that they made the transition to 5G without adding more towers, which would pose issues given that 5G signals don’t propagate as far as 3G/LTE.
