Does one have with every huawei device manufacturers guarantee?

So on the package (box) are yes codes that you can enter online and can see until when the warranty is. So, every huawei device has 2 years manufacturer warranty and 2 years warranty from the supplier like 1 and 1, vodafone, etc?

The manufacturer's warranty does not grant the manufacturer the dealer, the mobile operators give a full 24-month warranty on their contract phones, which has nothing to do with the manufacturer's warranty. Huawei granted on smartphones, tablets and PC 24 months manufacturer's warranty

So if I buy a handy ovp at the private seller, I have 2 years manufacturer warranty

If you get the original proof of purchase from the seller then yes.
