WHAT Dose GSM, Lock & Unlock Mean
The term GSM means - Global System for Mobile Communications. It is the most popular standard for unlocked mobile phones in the
world. GSM differs significantly from its predecessors in that both signaling and speech channels are Digital call quality, which means that it is considered a second generation (2G) mobile phone system. GSM is an open standard which is currently developed by the 3rd Generation Partnership Project (3GPP).
From the point of view of the consumer, the key advantage of GSM systems has been higher digital voice quality and low cost alternatives to making calls such as text
messaging. The advantage for network operators has been the ability to deploy equipment from different vendors because the open standard allows easy inter-operability.
Like other cellular standards GSM allows network operators to offer roaming services which mean subscribers can use their phones all over the world.
To help you further understand, GSM is simply a standard used by phones to communicate with each other. It is a new standard that has been adopted to all new models of phones and is now so prevailant that it has become the 'norm' in the phone world.
Now to answer your other question, with respect to locked and unlocked phones. bar phone is locked when it is attached to network. For example if you go to AT&T and purchase a phone from them then that phone is said to be locked unto the AT&T network and as such it cannot work on another network such as SPRINT or NEXTEL. Thus an unlocked phone is a phone that is bought, that is not locked to
any network. And as such it can work on any network.
The network it will lock unto will depend on the SIM card you put into the phone. For example if you put a AT&T sim in an unlocked phone then it will work on the AT&T
network. In the same way if you put a NEXTEL SIM card in an unlocked phone then it will work on the NEXTEL network.
However if the phone is locked to a particular network, like say for example AT&T then changing the SIM card in the phone to another SIM card from another network such
as NEXTEL will not work. This is because the phone is locked unto to AT&T network and as such will not work on any other network.
Yes, you can use the prepaid SIM card on the phone once the phone is either unlocked or on the same network as the SIM card you are going to put into it. It should work just fine.
Unfortunatly is isn't possible to have more than one phone on the same line. It is possible to have more to than one phone on the same account, in fact, some providers
will allow many many lines on one account.
The reason why your unable to do this is that your phone has a ESN (electronic serial number) that assoicated with that line. What this does is allow your network to send the calls to your phone. If there is more then one ESN per line then it will cause problems receiving calls.
For example, I had wifi phone that i wasnt using anymore when i bought a new one, well my old phone was recieving text messages that my new one was supposed to get, but the new one would get all the calls. To resolve the issue that had to erase the programming on the phone.
