"Hi, my name is Ben. I'm with the Cell Phone Broker in San Jose, California. Today, I'm going to kind of show you how cell phones work. Cell phones run off of three different types of networks in the United States. You have GSM, CDMA and iDEN network. iDEN is what Nextel network utilizes. That's what allows you to use the walkie-talkie service. CDMA is what Verizon, Sprint, Alltel, Metro PCS, those companies run off those networks. Or, I'm sorry, that network. Then you have GSM; that's what T-Mobile and AT&T runs off of. That uses the SIM card system which allows you to switch phones easily and, you know, kind of transfer out information a lot easier. On CDMA, it requires you to log onto a system to change out your phone. It's a little bit more difficult. Like I said, on GSM, you can just take out your SIM card, switch out the phone and you're ready to go. On the iDEN network, the only company that uses that is Nextel and it is, you know, it is mainly focused towards its business users, construction users. They have some very durable phones and that's how that works. And, those are the three networks that cell phones run off of. And I'm Ben with the Cell Broker in San Jose, California.
