I'm guessing one of the main reasons for CDMA is because companies want to make sure they get more money out of you. GSM phones are not locked which means you don't have to pay At&T or T-Mobile or whatever every month for the next year or so. Once you pay, it's over.
Am I right? Is that how it work in US?
Hi Caro332,
Yep, in the end it comes down to money, them making more, the consumer getting 'less' for what they are paying compared to other countries.
Actually GSM phones by carrier here are still locked in to carrier, just as they are with the root business, but of course they carry a SIM so technically you can simply 'unlock the device' by using a pretty simple command (Sometimes you have to visit a website and pay a small fee for the effort.) But, this unlocks the SIM only, which means you can add another compatable SIM and 'use' the phone.
Sadly however, it isn't quite as easy as that, why? Because of the CDMA network, you may not be able get the phone to register certain services such as 'Data' regardless if you have rooted the device and have unlocked the SIM. But you also maybe lucky as I was. I change my old GSM Blackberry which was a verizon phone, and placed an AT&T Sim in it after paying $5.00 to unlock the SIM. Although, at home I couldn't receive Data signal, the phone worked fine. Also if I went into the city the Data would also work. Best of all, I could go to the UK or any other GSM countries and simply place a local carrier SIM in the phone and it would work!
What bothers me most about the whole thing is that we are prevented from simply purchasing a fully unlocked phone, either GSM or otherwise, and then be able to 'shop' for the best deal on a plan. If that became possible then there would obviously be more competition between carriers. That would in turn lead to more affordable costs generally and ignite the advance in technology for Americans. Alas, the carriers don't want that do they?
But as it stands, you can, by doing some research, get a better deal here and most importantly CAN obtain the GSM phones, I have my blackberry right here, but it was NOT regular verizon issue (Which is standard CDMA,) like I've mentioned, I had to request it because I travelled. These money grubbers don't want everyone to know so do not offer them normally and certainly do not advertize the fact they are available.
