The calling part works great. The texting part, not so much. You can't add a photo or attachment to a text message. Worse yet, I paid for the premium membership. They were giving me a couple of word responses about the text issue until I asked for a refund. Now no response from customer service for three days. If you just need a calling app, go for it. But if you want a all in one calling and texting app, this ain't it.

Completely useless, couldn't even get past the initial setup because the phone number verification methods did not work. Why have "WhatsApp" and "Phone login" as separate options when they're actually BOTH thru WhatsApp and neither of them work?

Hello. If you had an issue during login by official WhatsApp bot - please try send us a message in describing at what step you've seen an issue + what did you see on the screen actually. We dont receive any complains about login process usually its quite simple and easy. We will help you for sure.

No option for adding anther call to make conference call. It's annoying as we have to make many con-calls in our profession. If you give that feature then I will reinstall this app.
