I was going to loose a paid collaboration just because the brand wanted us to talk on WhatsApp but I’m so happy that this guys helped me through it and I was able to use the number on WhatsApp. I am the happiest person alive right now

Unsafe App – Harassment Ignored
7Swan
Harassment from day one via the number provided by SLYFONE (especially on WhatsApp). Support refused to change it and kept telling me to block the contacts. My subscription was auto-renewed while I was still complaining, and I even received a suspicious call from Nigeria. I had already struggled to get a new number because the first one didn’t work with WhatsApp despite prior confirmation. Unsafe service. Not recommended.
This update includes some bug fixes.
