I bought the Huawel Y6 Elite from this deal, which included a Vodafone sim card.
I found that mobile data keeps getting used (causing the credit to keep decreasing). So I tried to stop this (just want wifi use only) by doing all these steps :
turning off mobile data in settings.
restricting background mobile data use on all apps, as well as system apps.
turning off 4G and using 3G only (as some articles suggest this would help).
But I just cannot stop mobile data from being used. For e.g. Whenever I take a picture, the mobile data usage increased by about 5 KBytes. The only way to stop this that I know of, is by going into Aeroplane Mode.
The phone itself is in quite pristine state, as when bought. Have not downloaded many apps yet.
BTW, this is not related to the Vodafone sim, because if I replace it with a Telstra sim, the same thing happens. So, it is more than likely to do with the Huawei phone.
Hope some OzBargainers have figured this out, and can help.
I found a few articles about Huawei phones collecting user data, and wonder if this is related to the mobile data being used, e.g.

At this stage, I am keeping an open mind, perhaps it is just something I missed out doing.
Thanks and appreciate any feedback.
