Karbonn handsets are locked by the carrier that sold them or by a code derived from the IMEI. This page lists the 90 models our device register recognises, explains how Karbonn locks a handset, and links the checks and unlocks that apply to it.
Most handsets from this brand are either code-locked (the phone prompts for a network code when a foreign SIM is inserted) or released by the carrier that sold them. Which one applies depends on the model year and on whether it was sold through an operator — the IMEI check tells you before you pay for anything.
The practical consequence is the same for every family: the phone works, and it refuses to activate on a SIM from another network until the record against the IMEI changes. Wi-Fi keeps working, so the device looks healthy right up to the moment the new SIM goes in.
