I was working at Radio Shack in 1995-1996 and mobile phones were definitely starting to grow in popularity. By then, you already had subsidized “free” phones and mobile plans were around $35 a month.
When we say that "Mobile is eating the world" or something, we are not talking about the mobile phone we can make a call with but the phone we can use the internet and applications with.
Your data is about the mobile device that allowed us to make a phone call.
If you say that "this is also data" then we have that kind of data for chatbot as well, e.g., the number of sales of Alexa and Google Home devices, or Messenger installations, etc.
