You'd think with the way carriers are more than willing to meddle with the internals of Android that they'd have put in some controls to completely shut down the data modem if there isn't an active data plan.
The telcos assume -- correctly -- that handsets can be modified. The telcos fear -- correctly -- that modified handsets could be used to obtain service without paying for it. Thus they don't bother with security in the handsets other than carrier lock. It's all server-side.
What your handset is doing is either trying to negotiate with with a provider's tower for service or maintaining the minimum necessary for 911 emergency calling. Or to get you to the portal so that you re-up your service. :)
High data costs? Those are just to discourage you from ditching your wired ISP the way you ditched your wired telco.
By the by. Android already has a radio and IMS shutoff. Always has. No meddling needed. Open the dialer and key in "*#*#4636#*#*". That will bring up the Test menu. Drill down into Phone info. Airplane mode may or may not do the same thing; depends on the OS version, I think.
