About this category

Sigma Plus is the current Sigma software for phone repair: flashing, unlocking and IMEI repair across Exynos, HiSilicon, MTK, Qualcomm and Unisoc chipsets. It is one product with the full model list — no brand packs to buy separately — and the digital licence runs the same functions as the box/dongle version.

🔧 What the software does

  • 📱 Flashing firmware on supported chipsets
  • 🔓 Unlocking network and service locks
  • ⚡ IMEI repair on supported models

Coverage spans Exynos, HiSilicon, MTK, Qualcomm and Unisoc devices under one licence, so a single install handles the whole workshop queue instead of one brand at a time.

🔑 Digital licence

The digital licence is account-based: no box, no dongle. Create an account on sigmakey.com, install Sigma Plus, then log in with that email and password. Internet is required for all operations.

Licence terms are set from activation and run for the purchased period — 3 days, 1 month or 3 months. PC changes are limited: the 3-day plan allows up to 3 PC changes, the monthly plan up to 9, with a minimum of 24 hours between changes. The licence length is the access window itself, not a trial period.

⚡ Setup requirements

  • An account on sigmakey.com — Sigma Plus logs in with the email and password registered there
  • The Sigma Plus software installed on the working PC
  • A constant internet connection during every operation

The packages listed above are how this shop supplies access to the tool as a licence for a set period.
