Phone number and SIM glossary for people moving countries

Short, self-contained definitions of the terms carriers, banks and regulators use when your number crosses a border, with the Hindi and Chinese carrier vocabulary where it differs.

What lands here first

One short, self-contained definition per term, so a sentence in a carrier's fine print stops being a guessing game. Terms appear in the words carriers actually use, including the Hindi and Chinese vocabulary where it differs.

  1. 1Roaming pack, fair usage policy, short code, OTP
  2. 2Number parking, porting, MNP and UPC
  3. 3Grace period, validity, suspend and hold (停机保号)

Each page goes live only once its sources check out, and every arrival is dated in the rule changes log. If you need one of these sooner, write to [email protected] and we will move it up.
