Depends what you mean. "Bandwidth" on a radio system consists of two things:
1) Radio capacity between your device and the mast
2) Connectivity between the mast and the core network
The majority of cellular systems around the world are limited at 1. Governments only have limited amount of radio capacity and licence this capacity. Networks bid for capacity, and then make a cost decision about where to deploy. You may find the radio spectrum in your area is saturated for the number of users. Three may have additional capacity they can deploy, or they might have deployed all they own.
Radio isn't really a suitable medium for broadband in high use areas (e.g. towns/cities) for this reason. The ideas behind 5G might change the parameters if lots more micro-cells are deployed, but that will take a long time.
