The subscriber’s own language
Support that answers in the language the question was asked in.

NSK·SOL·02
An operator with tens of millions of subscribers takes most of its contacts in one language, and loses the rest. Callers who use a second or third language wait longer, repeat themselves more, and abandon more often.
The material needed to fix it is already in the call archive. Nobody had labelled it.
Move across the plate.
Move across the plate. Under the room the subscriber reaches lies the one that answers.

Tariffs, balances and device questions answered in the language the subscriber used, on the channel they chose.
Symptoms matched against known faults and network events before an engineer is dispatched.
Every live conversation drafted for the agent, who edits and sends, with the source document beside it.
Breach notification within the window the regulator sets, with consent recorded per channel.
Voice retained ninety days. No transcript leaves the operator’s own cloud or region.
Language coverage is stated per intent, so a gap is visible rather than guessed at.

We will tell you which part of it is a model problem and which part is not.
