Sounds very simplistic, but you can see by the sheer number of publicly and freely available white papers and reports how each OEM tries to sell its story (of course there’s nothing wrong with this). But what it does do is flip the natural and logical order of things.
Ideally, you’d have a situation where the MNO, understands its customers’ needs and asks vendors to develop solutions to effectively meet those needs, but instead now what happens is that this narrative of “what the customer needs” is driven by OEM’s very effectively combining two basic instincts of fear and greed: “If you jump on this bandwagon there are billions to be made (GREED) and if you don’t, your competitor will, leaving you far behind. (FEAR).”
You don’t have to take my word for it, just Google “IoT forecasts” … and you’ll see exactly what I’m talking about.
Unfortunately, the same attributes have cascaded down to the Roaming & Interconnect industry, Is it any wonder then we completely missed the bus on VoLTE Roaming, or why so many MNOs are ready to lease their IMSIs or even allow their Global Titles to be used by third parties, are ready to jump on the next bandwagon of a “must do technology”, with little appreciation of how the golden hen of roaming is being sacrificed on the altar of short term gain
