Of course, being the paid shill of Nokia that he is, he comes up with some very convincing FUD that only he can make up by twisting the facts. As for SIM cards, perhaps he should have been there in 1992-1995 when the goal was NOT to adopt GSM, but rather to improve US AMPS. US AMPS was based on IS-41 and it had no sim. So the proposed adoption was for without the idea of SIM card. We had to modify the air interface and it was just too much to ask the Carriers to also change their entire billing and user interface methods. But then ERIC L was not there and in those discussions, so how would he know. As far as the out of context paraphrase of PJ, the carriers did not want just any phone on the network back then. At the time, as you have probably conveniently forgotten, SIM cards were having some major control problems from the Euro carriers and the US carriers did not want the same issues, so they asked that there be no SiMS. CDMA is in fact sensitive to the rogue phone on the network and to that end; they have a required failsafe mode in them which turns them off if they do not respond to a power down and limit control sequence. BTW - WCDMA has the exact same problem and requirement. When QCOM went to China, China Unicom asked that Qualcomm add the SIM card type capability so that their marketing push, which at the time included references to the GSM SIM, would not change or be modified. It was for that reason that they added the RUIM to the phone in about 4-5 months time. They still to this day provide both RUIM and SIM interfaces to the chipsets. IN fact, now that QCOM is approaching the top of the UMTS market they are leading in putting a SIM in the WCDMA phone set. His ridiculous claim that there is no expertise in SIM and RUIM is disingenuous at best, and an extrapolation of his close Nokia bashing conversations. I would suggest that he stick to those events where he really does have first hand knowledge of the real facts. Take care, Quicny. Thanks for waking me up and getting me to read the ERIC L total blather. Now back on ignore. Of course there are all the forgotten tales of the 5.5v and 3.3 V sims which on NOKIA phones just died for no reason and swallowed the entire programming. I remember that one in 1997 with huge recalls.
