Cell Phone Companies



Cell phone companies

The term cell phone companies basically refer to the network providers, not the manufacturers of the cell phones. There are some major mobile phone services providers in the US market at present namely Sprint, T-Mobile, Verizon, and Cingular/AT&T. These major cell phone companies work on either of the two main network systems the GSM network or the CDMA network. T-Mobile and AT &T mostly use GSM or Global Systems for Mobile communication and Verizon and Sprint mainly use the CDMA i.e., Code Division Multiple Access technology. Some other network service providers provide both network services and some compromise plan.

Decide on the right cell phone company is a challenging job. Ideally there should be less drop calls and affordable monthly charge. The cell phone manufacturers sometimes allow the cell phone companies to put SIM lock on the phones as incentive. These particular cell phones are called locked cell phones. The cell phone companies using the GSM network can avail this locking system for keeping the subscriber and network information locked in the SIM card, so for changing the network the customer has to unlock the cell phone and change the SIM card. The advantage for the customers is that they get the mobile phone at much lower price along with cheap cell phone plans. This kind of deals require the customer to stay tied to a particular cell phone company for some agreed upon time. Cell phone companies generally come up with populist cell phones plans to allure the customers.

Cell phone companies operating on the CDMA network do not provide card enabled cell phones. The CDMA technology rather requires the subscriber and network information hard coded in the phone memory. So upgrading a phone requires changing the phone altogether. There is a SIM like alternative card called R-UIM for CDMA but this is yet to come in the US market.

Each of the networking system has its own advantages and disadvantages. CDMA is a comparatively younger technology than GSM. In CDMA technology the analog signal is converted to digital signal and break up in smaller parts while passing from one site to site. This enhances the signal quality and speed up transmission. So speed and quality transmission is the advantage in this network system. But if you want to change network, you need to change the cell phone and its memory is hard coded and will not render any service for other network. GSM technology allows keeping the information in locked or unlocked SIM cards so it can be changed when required. This feature is particularly helpful when you are visiting rural areas or travelling abroad. Since major cell phone companies subscribe to either of the networks, you need to select your carrier and the cell phone plans carefully and according to your specific need.

Most cell phone companies like to keep the customers tied to them for a one or two year service agreement. For this they provides cell phone plans with lots of alluring features like cheap talk time, free incoming call, free talk time on weeknights and weekends etc. and many more. They sell the phone at a much lower rate than the retail price. But still most subscribers complain about rising monthly bill with the cell phone much higher in comparison to the land line phone. With advent of technology and more attractive features like text messaging, net surfing, camera, storing video and music etc. the monthly charge will be still higher. So apart from picking the right cell phone company you should also select the right plan and affordable features before signing any contract.
