Telco companies are just greedy, the majority of telco networks are designed to handle max maybe 30% of subscribers instantaneously accessing the system, any more and the system dies, recently an incident occurred which caused residents of locally 3 major counties to phone 911, the network was unable to handle the congestion and shutdown.
When telco companies do network planning they use forecasting and statistical analysis to predict what is the probably percentage of users accessing the system at any 1 time, unfortunately with smartphones which theoretically have an always on connection, their forecast were off by a large margin and now they need money to upgrade the system to handle the extra volume that they did not predict, cue Google/FB lawsuit
