Only your local Huawei office can tell if and when it will be released in your country. Apparently, the "september 2019" date mentioned by the link you gave wasn't realized anywhere in the world.
Just in case you didn't read what https://www.trustedreviews.com/reviews/huawei-mate-30 says about it: it's severly limited in the software it runs.
Why did you select this model to buy?
I would like to buy Huawei Mate 30 lite, but it looks like it still isn't revealed. Does anyone have any information about it? I am from Europe and hope it will be available here too.
If this phone won't be available, can someone recommend me an alternative?

Tnx a lot!
