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 $). |

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... |
