For a cell phone to be unlocked, it means that the phone is able to use any SIM card from any phone network type. For example, a locked Verizon Wireless phone would be unable to accept and function with an AT&T SIM card, whilst an unlocked Verizon Wireless phone would be able to accept and function with an AT&T SIM card.
An unlocked phone is when a phone isn't forced to be used with a certain network. It is available to be used with certain networks that accept these types of phones.

what is an unlocked cell phone
an unlocked phone could mean one of two things. One, the phone belongs to a GSM carrier (like T-mobile, or AT&T) but being that it is unlocked you can use it with any carrier that requires a sim card. The second can mean that it is a CDMA phone with GSM capabilities normally on a Sprint or Verizon Global phone meaning it is a CDMA phone with a sim card slot and as long as it is unlocked it can be used also with any other carrier that requires a sim card. However it has nothing to do with what is on the actual phone, so even if it says T-mobile it can still be an unlocked phone.
Unlocked phones means the phone can be used with any carrier. Keep in mind you may not be able to use all of the phones features.
If unlocked, then yes.
yes
A cheap unlocked cell phone would probably be a used flashed phone. A flashed phone is a phone that is able to be used by other carriers. New ones wouldn't be cheap.
Yes, this term is often used for unlocked iphones.
No, "no carrier" and "unlocked" do not mean the same thing for a cellphone. "No carrier" typically means the device is not currently associated with any specific mobile network provider, while "unlocked" refers to a phone that can be used with any carrier's SIM card, not restricted to the original provider. An unlocked phone can be used on any compatible network, whereas a device labeled as "no carrier" may still require unlocking to do so.
It means that it can be used by anyone.
Yes it is possible to see if your phone is unlocked. You can borrow a sim card from someone who has a cellphone with a different service company. If the card works and the phone thinks its your friends phone then your phone is unlocked.
