For the chips? Negligible. 4G services were being deployed in 2010. So 3G wasn't even cutting edge at the time. Every cut-rate cell phone being sold was capable of 3G.
Also, AT&T had not yet announced any plans to discontinue 2G service.
It seems even more insane that they would use a module that didn't support enough frequencies to be moved to a different network via a SIM card & software update.
Yes, and that is forward-thinking, common-sense thought. Not something used by the Corporate controller looking at what is cheapest now.
They could probably be moved to the T-Mobile network with just a SIM card change, if they still offered 2G service.
Nissan chose the cheapest train and rode until it ran out of steam. Now, instead of having to replace the radios in all the older cars, they only have to pay to replace it for the ones willing to fork over the $199 co-pay. Still going for the cheapest option, and I'm sure it was the least expensive, 3G only, radio they could get.
