About this category

Sigma Plus is PC software for GSM service work, paired with a Sigma Plus Box or Dongle. The two hardware options run the same program: the Box ships with cables and an FTDI box, the Dongle is the same software without cables. Technicians use it for flashing, unlocking and IMEI repair across the major chipset families: Exynos, HiSilicon, MTK, Qualcomm and Unisoc.

🔧 What the software does

Work is organised by platform rather than by a long model list, so one installation covers the typical repair bench jobs:

  • Flash — firmware reading and writing
  • Unlock — network and bootloader work
  • IMEI repair — restoring correct device identifiers

🔐 Licence and access

A brand-new Box or Dongle gets 1 year of access after its first activation. An account on sigmakey.com is tied to the hardware and is required to use the software. When that initial year runs out, access is renewed with a 6-month or 1-year activation — this is a straightforward continuation of the same licence, measured purely as duration: half a year or a full year of continued access to the tool after expiry.

Some operations require an internet connection for the Box or Dongle. There is no PC-change limit, so you can move the setup between workshop computers without consuming activations — only the licence period matters.

The activation packages above are how this shop sells continued Sigma Plus access: a 6-month or 1-year period added to an existing Box or Dongle, delivered against your sigmakey.com account.
