I believe it does. Most new phones have built in antennas that aren't visible. On older models you have to put out the antenna yourself. This helps on older models.
A cell phone signal booster increases coverage because it has a signal amplifier, reception antenna and an internal broadcast antenna which are similar to the technology used with cellular towers.
The modern dy cell phone really has no need for an external antenna. As the number of cell towers has increased so has the signal strength.
The purpose of a cellular phone antenna is to transmit and receive radio signals between the phone and the cellular network tower. The antenna helps to boost the phone's signal strength and improve communication quality.
Cell phone boosters are designed to increase the signal strength of phones to increase call quality. There are many cell phone boosters available on the market today.
A cell phone signal booster includes three parts: the outdoor antenna, the signal booster, and the indoor antenna(and cable to connect them) The outdoor antenna communicates and receives a signal from a cell phone tower nearby and transmits a signal to the booster. Then, the signal booster amplifies the outdoor signal and sends a stronger signal to the connected indoor antenna. The booster’s indoor antenna broadcasts the amplified signal to all cell phone or cellular devices throughout the home or office.
Cell phone signal boosters usually use an additional antenna which is placed in an area where reception is relatively stable, often outside. The extra antenna inside will then rebroadcast and amplify the signal to the external antenna - essentially bouncing the signal from point to point until it gets to the spot with good reception.

There is usually no easy way to increase the signal of a cellular phone, although some models have better range than other models. One possible way to increase the strength when you are in a car is to have a "car-kit" which boosts the signal strength and uses an external antenna (on the outside of a car). If this is a critical concern for you, you can probably avail yourself to a "transportable" phone, which operates at a higher power than a standard cell phone, but these are also several times larger and heavier than a standard phone and really only a solution for those who must be able to make calls in fringe areas.Other tips that will improve your signal is to use the phone outside when possible, the range will be significantly decreased if you are inside of a (metal) car or inside a building. Extend your phone's antenna if that is possible on your phone and hold the phone as vertical as you can. There are always some "dead" areas where cellular signals are weak, obstructed or have significant interferrence, so moving a few meters will sometimes make for a much clearer call. If you have seen the clear stickers with a gold foil "antenna" design and claim to increase your cellular signal, they are a waste of money and have no plausible basis on why you could expect them to help.
A cell phone repeater is a bi-directional amplifier that is used to boost cell phone reception in an area. This is usually done with an antenna, a signal amplifier, and an internal antenna. Cell phone repeaters are also found inside large buildings to help with cell phone signal in a building.
A cell phone antenna is used to pick up a signal for the cell phone. It is used to create a signal so that a person can give or receive calls. It also can pick up a wifi connection.
Yes, there are such things as cell phone boosters that are used to improve signals. They work by enhancing signal strength.
