Not sure how this one will work out, but these are my two cents:

In the 2017 Mobile World Congress, most of the Telecommunication companies were focusing on two main things: IoT and 5G.

I think these companies want this because if users adopt IoT more BandWidth and data consumption will occur. 5G will also allow for higher speeds and targeting capabilities.

Generally speaking I think that a better IoT infrastructure will be of value to this type of companies. Not sure if IOTA is the way to go, but there certainly is a lot of interest from corporations to make this work for them, so perhaps there will be a push from their side to make this work on some blockchain platform.

Perhaps based on this, it is worth keeping an eye on this type of cryptocurrency.
