Sorry, here it is:
\startluacode
fonts.handlers.otf.addfeature {
name = "phone",
type = "substitution",
data = { [0x260E] = 0xF003A }, -- doens't work
}
\stopluacode
\definefontfeature [phone] [phone=yes]
\definefallbackfamily [mainface] [serif] [MarVoSym] [range=0x260E,
features=phone] \definefontfamily [mainface] [serif] [TeX Gyre
Pagella] \setupbodyfont [mainface]
\starttext
substitution: \utfchar{"260E} %% black telephone
\blank direct:
\resolvedglyphdirect {name:marvosym}{n:Mobilefone} %% works
\stoptext
%% glyph name and slot taken from
%%
%% \usemodule [fnt-10]
%% \starttext
%% \ShowCompleteFont{name:marvosym}{10pt}{1}
%% \stoptext

The question is how to input the name in the Lua code (here:
“Mobilefone”). And it seems like substitutions don't work beyond
0xFFFF.
