Just about anywhere !.. In towns & cities - they're placed high up on tall buildings or self-standing masts. The mobile phone network uses microwaves to relay the calls - so it needs 'line of sight' from one mast to the next.

Portable (cell) phones are low-power devices - they have a limited range. Each mobile-phone communicates with at least three mobile 'masts' to establish its location so the network can keep the call connected.
