Things never stay the same, what we see today would be different the coming day. Similar is the case with AT&T. Back then, it had dominated the phone service completely. People were bound to use AT&T’s service no matter what; rather it was compulsory to have a phone from the company. People could not even buy a phone of their own choice from anywhere but they were limited to have it from them on rent.

The time changed and the AT&T monopoly shattered. Then different companies emerged and the competition among them heated up, as happens in an open market.

Even in it witty marketers introduced contract plans, where a consumer could not switch his service for a specific period of time and was bound to stay with a service provider despite being treated unfairly in terms of hidden charges in packages offered. Anyhow cell phone is better than complex landline service providers as far as billing is concerned, but in cell phones call dropping and poor voice quality is another issue.
