Re: Better for Promoting CDMA Abroad
They do, its called a RUIM, no North American CDMA provider uses it. Blame the cell companies, not the equipment makers, some cellphones have the slots under the batteries, or atleast traces on the PCB for a RUIM card. Having no cards means they can charge you for a phonebook transfer, and a non-geek is at their mercy. Nor can you switch phones without their approval (another fee and only their handsets can be used), plus they can control what phones go on what tiers more easily (they can still always block by ESN (CDMA)/IMSI (GSM)) (a million ways to get more $). |

VZ has alredy announced that they will migrate with AT&T and other international carriers to LTE.
Conversions are easy. Cell towers are capable of having more than one radio. Some have 5-10 radios. Replace one radio with a LTE radio and as demand increase and CDMA sets decrease you add more LTE radios while taking away CDMA radios.
That's how the TDMA to CDMA conversions went. |

Cool link. Wondered how CDMA was doing...
I see little reason CDMA couldn't incorporate a SIM card type system. It's just a wireless standard is it not? I mean, the network can adapt to a new handset quickly enough, so there should be little technical reason for this NOT to work (eventually...).
I'm no wireless expert, but it seems like this might be an obvious idea - to be able to take a phone (say, CDMA) and use it on any network of the same type...
I don't see the sense in keeping it so locked down if it's the same exact underlying technology.
One should be able to buy any (for example, CDMA) Nokia, Motorola, whatever, and activate it on the plan of your choice.
All that marketing speak about "OUR network standards.." sounds like crap to me. It's CDMA, is it not? There are already standards by which these things work... |

said by wifi4milez  :Apparently CDMA is actually going away in the next few years. The 4G roadmaps all include non CDMA variants as their core! Assuming all goes according to plan, Verizon will be a GSM provider sometime between 2010 and 2020. Interesting. I remember when 3G GSM services were deployed by AT&T, they were based off CDMA technologies, but they weren't directly compatible with CDMA. That is, you couldn't take a 3G CDMA device and roam on a 3G "GSM" network. I am wondering if the GSM-based 4G solution would work in the same manner.
Also, I can't picture Verizon simply throwing away its existing CDMA-based infrastructure.

The above is the status of CDMA worldwide.
