As a Nokia Mobile Phones employee in the mid 2000s, I can confirm this was indeed the case. The US wouldn’t pay over $100 for a handset, and Nokia was already losing money on hardware in the phone sale to have it subsidized by network providers. Nokia wanted to add tech and capability, but the high end stuff didn’t sell at a profit and carriers wouldn’t sell phones that were more expensive than their customers would pay. Apple was an exception due to marketing as “premium”.
