Mike,
I'm not sure you really answered the question. (At least you didn't answer the question on my mind.
)
You explained that, "[w]ith CDMA, the carrier must enter the device's unique ID into their system to permit the phone to work on their network." You also mentioned that, "[w]ith GSM, the carrier just enters the SIM card ID."
What I don't understand is this: if CDMA phones were engineered with a SIM card that carried an ID, why couldn't CDMA carriers just enter that ID into their system to allow any CDMA phone to work? It's clear from a business rationale why they wouldn't want to do that. One would think that the GSM carriers have the same business interests in mind, yet, they have the SIM card approach. Are there any
technical reasons you know of that prevents CDMA carriers from going the SIM card route?
Thanks,
Twain
