I used it once and suffered a lot. I had so much trouble in only activating this messenger because once it ask my no and gave it and it send me an otp on no to confirm my phone but where do I have to write this otp. There was not a single space. On the whole screen it was showing write the otp.i uninstalled and installed nothing happened. I installed an old version of it from my browser and it worked perfectly fine.in adds it says free but nothing is free.rs get deducted on doing message offline and no problem when the net is working. Dont like the concept of it. I do not recommend it.
