What is Bluetooth?
Bluetooth is a radio technology that transmits digital voice and data signals over short distances (approximately 32 feet or 10 meters) between various electronics devices such as computers, PDAs, cell phones, televisions, and so forth without a wire connection.
What are some of the advantages of Bluetooth?
Bluetooth uses low transmission power and therefore conserves battery power. It is inexpensive and, unlike technologies such as infrared, does not require line of sight to operate. It can even go through walls. It eliminates the need for wires and gives the user much greater mobility.
Are there any disadvantages to Bluetooth?
Because it is possible to "steal" signals from the air, Bluetooth like any wireless technology opens up the possibility of having signals/data intercepted by others. However, users can enable features on Bluetooth that are felt to be quite effective in preventing this theft from happening. Users are able to instruct their Bluetooth devices to accept communication only from certain "trusted devices". Signals from other devices then require the user to grant permission manually.
How can I find out more about how Bluetooth can be used and how it functions?

What is a GSM phone?
GSM stands for Global System for Mobile Communication and is the transmission technology that is the cell phone/mobile phone standard in most European and Asian countries. Having one standard allows networks/phones to communicate with each other. In the US, At&T and T-Mobile are the primary GSM cellular service providers. GSM cell phones all possess a removable SIM card which contains the personal account information of the user. A full description of how GSM operates is included in Wikipedia.

I've heard that prepaid phones aren't really very economical, are they more expensive than traditional plans?
Prepaid phones tend to have a significantly higher cost per minute. However, if you don't use your cell phone very much, a prepaid option can save you money as you aren't paying for minutes you won't use. It really depends on your usage in many instances.
It's also important to note that many prepaid services now offer monthly plans without a contract that compete very well with traditional cellular plans as far as cost. These are more suitable for those who use their cell phone more. In fact, some prepaid services offer competitive unlimited plans.
Whether you purchase a prepaid cell phone or a traditional plan, you should be sure you know your usage, all applicable fees, and so forth to determine which makes most sense.
Are prepaid cell phone networks reliable?
Many traditional cellular carriers provide their own prepaid cell phones and they operate off of the same networks as those with a traditional plan. In addition, prepaid carriers such as Net10, Tracfone, and others typically use the same networks as well. Before you decide on any cellular provider, you should always check coverage to be sure it will meet your needs.
I need a family plan, do any of the prepaid services provide them?
There are a few who have family plans. Tracfone and MetroPCS do offer these.
Why advantages does a prepaid cell phone plan offer?
Primarily, you don't have to commit to the service. There is no credit check and no contract to sign. In addition, they can be good in some instances to control spending. Parents in particular like prepaid phones because if they purchase 60 minutes for a 13 year old, they know their budget won't be exceeded without their knowledge. If usage exceeds the 60 minutes, they would have to go in and purchase additional minutes.
The primary disadvantage is that you have more limited phone choices and often have to pay more for the cell phone itself.
What is a SIM Card?
A Subscription Identity Module is a smart card about the size of a postage stamp that is present in all GSM cell phones.
What functions does a SIM card perform?
A SIM card possesses quite a bit of memory, 64 Kb is not unusual. The card identifies you, the user, to the network and is actually the part of the cell phone that has your specific cell phone number attached to it. (This allows owners of unlocked cell phones to switch out the SIM cards to a different phone and yet maintain their same phone number.) The SIM card stores text messages, phone numbers, and potentially music and video files. Use of cell phones for ticketing and payment functions is anticipated in the future by using SIM cards as well.
Is there anything else I need to know related to SIM cards?
Because SIM cards contain a great deal of personal information it is important to be sure all such information is destroyed before trading in or recycling cell phones to assure that sensitive information does not fall into the wrong hands.

What is SMS?
SMS is the acronym for "short message service". SMS is essentially what is also known as "text messaging". The most common uses of text messaging on cell phones are personal communication, brief messages to family and friends, and the submission of queries for the purpose of retrieving information from the internet.
Do SMS services cost more?
Check the plan that you use. Generally speaking users either pay a per text fee or it's a bundled expense within their plan. There are many plans that offer unlimited text messaging as well as unlimited voice calling. In fact, there are even a handful of text or data only plans that allow users to send (and pay for) SMS messages and so forth without paying for voice calls they won't use.
What are the advantages of SMS over voice calling?
The primary advantage is that it allows you to send a quick message even when you aren't able to place a voice call. For instance, if you are in a meeting, at church, at a performance, and so forth, you could still respond to an important message without disturbing others.
What is a Smart Phone?
A smart phone is basically a type of cell phone which allows internet connectivity for web browsing, e-mail, faxing, voice mail, and data transfer between the phone and a computer in addition to other functions. PDA (personal digital assistant) cell phones are usually considered a type of smart phone.
