A: A SIM (Subscriber Identity Module) is a small memory chip that fits into some kinds of cell phones (GSM). The SIM carriers your phone number, carrier information, address book and other data. When you get a new phone, you simply take this memory chip out of your old phone and put it in your new phone (assuming the phone is not 'locked' to a different carrier). You can also use a different carrier and phone number in your current phone by putting a different chip in (again, assuming your current phone is unlocked).

A: GSM phones use the GSM network and have a SIM card in them. The card carries your data, such as your phone book, your number and carrier information. You can switch the SIM card to another compatible phone and all your data, your number, and your cell phone plan, can be used on that phone. Likewise, a different SIM card can be used in your phone, with different data, or with a different carrier (assuming your phone is unlocked). Phones from T-Mobile and AT&T are GSM.

A: Bluetooth is a wireless networking technology that replaces cables. If you have a Bluetooth phone and Bluetooth handsfree headset, you can use the headset to make you calls and you don't have to have a cable between the phone and headset. The devices communicate wirelessly. Other uses include hands free car sets, syncing data between your cell phone and computer, sending images to your computer, etc.

A: Most of our phones are world phones and should work with no problem. Please check with your carrier for applicable roaming rates.

A: Most modern cell phones use lithium ion batteries. They last about 400 recharge cycles, and gradually lose their ability to recharge sufficiently. If your phone is a couple of years old and the battery isn't charging up well, it may be time for a new one.

A: First of all, don't use your cell phone when driving, because as health risks go, that's the major one. As for cancer or other similar health risks, there is currently no scientific proof that there is a risk. There are some studies that suggest possible risk, and other studies that show those are wrong. So what do you do? You may be able to reduce the strength and duration of your exposure to electromagnetic and high frequency fields by limiting the time you spend on a cell phone, and some suggest using a hands free kit helps by keeping the high powered cell phone transmitter farther away from your head.

A: In an office environment, you might look into getting a cell phone signal repeater.

A: You can, but you don't need too. You can leave it on and take/make calls while it's charging with no ill effects. I know, I've seen that email too... the one that says the phone will blow up. That's an urban legend that gets passed around by email.
