Another year has come to its end, and we want to thank all of you for your loyalty and support. Let`s see what was special about 2021.

This year, we paid much of our attention to HiSilicon and MTK devices.

As a result, we RELEASED a number of World`s first updates. Thousands of smartphone models of the years 2010 – 2021 passed through our hands.

For 10 YEARS in a row, we PROVED to be a multibrand tool. Of course, Huawei is one of our top brands, but now our customers can service such brands as Vivo, Oppo, Techno, Micromax, Infinix, Xiaomi, Samsung, and many others you can find on the shelves of any phone shop.

During the past 5 YEARS, we have DOUBLED the supported models count.

If you`re searching for a Swizz Army Knife for a phone repair shop, you`re definitely looking for Sigma. Trusted bloggers rated Sigma as a must have multi tool for every service shop owner.

We always do our best to release the World`s first solutions. No second hand or copied solutions for our clients!
