Problem with Whatsapp activation on specific devices

[Jillit1]

Dear friends,

Hopefully this is the correct place to ask, I'm just lost here

I've tried activating my Whatsapp account (not at the same time) on 6 different devices.

3 of them, didn't work: Galaxy S6, Nexus 5x, and Galaxy Grand Prime.

Whatsapp support has no idea what can be the problem

I'm attaching Whatsapp logs on 2 of those account... (I have also PCAP from one of the devices, if someone think it can help).

Obviously tried: with/without Wifi, with/without roaming, stock ROM/custom ROM, with/without root, etc.

I've changed my phone number on the logs, for obvious reasons

Anyone can help??

Thank you so much!!

Jill.
