US Cellular uses CDMA technology, not GSM, so, their phones do not use SIM cards.
A cellular phone, no matter what the provider, requires a SIM cart to be operational. Your provider may be able to give you a new SIM Card for the phone, if it is unlocked to work with that network.
No
Buying a used cell phone is a great way to save money. You will get a sim card when you activate the phone with your carrier.
You can not use a sim card in another cell phone carriers phone. They can only be used for the same carrier.
Yes, that is usually the case with a SIM phone.
A cellular plan for an apple phone is what gives access to make and receive calls. A sim card is for storing programs and contacts from the phone to be moved to a different location, not to make calls.
No...US Cellular is a CDMA and T Mobile is GSM. Incompatible.
A sim card is a chip in your phone that holds information as to your phones identity such as your phone number. A sim card can be transferred to another phone allowing you to have to same phone number as well as your contacts.
Well, the sim card works just like any other sim card in a CINGULAR phone, but if you have the unlock codes to your other phone, I'm sure it will work.
NO. The SIM card is NOT a normal SIM card, its only for that particular phone and for use on MetroPCS's LTE network it was activated with. If its taken out to be used in another phone, it deactivates, rendering the phone and card useless.
Only if your phone is sim free.
The function of a SIM card is relatively simple. It's not a super advanced item that controls your phone, rather, it is basically nothing more than a storage device for information useable by yourself and your cellular carrier. It has limited memory to save this information. And this 'storage device' is also the reason you can use someone elses phone, put your SIM card into it and have all of your phone numbers and information about your account on their phone. This is of course unless their cellular provider has SIM-locked their phones. Anyways, long story short SIM-Card = storage device.
