Can I connect a laptop through cell phone without additional charger or connections?
My cell phone has unlimited text and web. If I purchase a laptop can it connect to the internet through that phone without any extra charges or connections?
Depends on the phone and carrier. Read the contract because almost all carriers prevent you from tiering your cell phone as a modem but everyone does it anyways. Some carriers will detect that you are using the bandwidth too much and will decrease it's speed... for TMobile it'll go from 3G to Edge mode.
