What is the best option as alternative of BBM for BB10 OS?
I'm using Classic.I'm sure know BBM for BB10 is still working now,but almost all my friends (except one) are using android or iOS.
They cannot use BBMo,but BBMe is expensive for them.
They use only free apps.
I tried Whatsapp and Line and Telegram.
Those are no good for me because all of them need my phone number.I cant stand to expose my phone number to unreliable company or people.(I think BBM is the great in this point)
What is the best,or at least better?
My conditions are;
totally free
No needed phone number (or facebook account)
secure as possible
cross platform,at least available on 3,Android,IOS,and blackberry 10.
