A mobile phone.
It's call a NIC (Network Interface Card)
Paging is a mechanism used in cellular systems to locate and alert a specific mobile device within the network. When a call or message is incoming for a particular user, the network broadcasts a paging message to all cells or a specific group of cells to locate the user's device. Once the device responds, the call or message is then connected or delivered.
It is an abbreviation for cellular device. :)
It isn't, it is the same thing. The term 'Gateway' is used to depict the device that allows you to connect to devices outside of your network, as in you walk through a gate into the outside world. Fancy mumbo-jumbo really, just another word for the same device. Routers connect different networks, they route traffic between them. You can call them whatever you want, still the same device and the same function.
Technically they would be called 'Nodes'
Any device on a network is called a 'node'.

When it comes to cellular technology, the term "unlocked" has two different meanings. The first being someone entered your password to access the funcuality of your phone. You will not be able to tell if someone unlocked your phone. The second defination of unlocked refers to the ability for the cellular device to be functional with any service provider. To determine if your cellular device is unlocked depends on wether your cellular device is a CDMA or GSM device. If it is a GSM device you can tell if it is unlocked by inserting a different service provider's sim card. If the phone is still functional then it is unlocked. If your phone is a CDMA device then you will have to either call your bring it to your service provider and they will be able to access your device profile to determine if it is unlocked or not.
Call their 800 number and they will walk you thru it! If you are not subscribed, your receiver will not be activated and is of little use.
