Woah.....Wait A Minute.....!!!

More interesting reading, taken from an article titled "Dual-mode R-UIM Tech in Focus":

Don't get excited yet, though--I think this means that Cricket would have to own and operate GSM towers and switches in order for this sort of infrastructure to work.

There IS a method of getting CDMA provisioning onto an RUIM card, however. I think I remeraber reading over at Mobile - Files that a firmware-updated Nokia 6265i can do it, as well as a solder-hacked Apache/6700 series PDA.

Curious.
 
I give you exhibit A Berry!

THE THREAD WHERE THIS WAS DISCUSSED ALREADY!!

Actually you used the exact same phrase in that thread!!

Yes it is possible and it is true some of the PST stuff i use has support for this, and no they would not have to have GSM, a RUIM is a pretty like a SIM card or on a CDMA network its the ESN, just take it out and pop it out into another RUIM phone which im pretty sure its not as easy as that but maybe it is, never the less if cricket went to that system that would be kick *** and now that i think about it yeah they would have to put up GSM towers as well they dont have to but if we wanted to use a GSM phone on cricket then yeah we would and a lot of the CDMA nokia phones come like that. If anyone knows where we can get a RUIM phone that be cool i want to test one / just get a feel for one
 
The 6165i has a SIM-looking slot on it, but the manual made it very clear that you should not put a SIM card in there. I've always figured it was an RUIM slot.
 
well as far as i know a SIM card could go in there for Roaming in an country thats CDMA only but never the less i nver saw that the Nokia would pick it up but im sure its cause the soft on the phone had it disabled
 
ruim can go into a sim slot. a sim can NOT go into an ruim slot.
the phone has to be enabled in the firmware.
it allows subscribers of cdma networks which use ruim to roam in a gsm country simply by putting their ruim into a gsm phone. it does not work the other way. it is roaming. this would not make an iphone operate on a cdma carrier. but you could use it for roaming if you had a cdma carrier using ruim. which cricket does not.
 
would probably take some other updates also besides just putting a chip in a phone. i know on GSM, the sim is all subscriber information which is stored in the HLR and in turn VLR's. I don't know that CDMA use those, and if they did they'd have to update information via RUIM ID instead of ESN.
