They are standardized and oftentimes available in hardware but carriers disable them for obvious reasons.

  Sorry, what are the "obvious" reasons? Why should my phone supplier care to stop me using my phone abroad, say?

    Cause they can charge you more for international branded phones.

      Why doesn't the market work around such companies that are so antagonistic to their customers?

  do they really disable them? I always thought that LTE modems only come with certain frequency bands. I can slightly remember that the iphone 5 only had 2 or 3 frequency bands while at the beginning of lte some providers did use the frequency which the iphone had more often, so some providers had better lte support. But I can hardly remember, it was some years ago and my provider switch basically came within the lte rollout. I mean it probably also consumes more energy to scan more bands (ok that could be solved with software)
