Ltimas Blackberry BBM Enterprise Review

I downloaded BBM Enterprise on a Samsung S5 Android. The charge for this service is $2.49 every six months.
The S5 communicated with an older model QNX Blackberry 10 phone.
I will continue using this service and provide an update in several months.

Update 2022-10-01 Although, I tried several times it did not provide utility. I had to make a request to credit company to stop the reocurring charges. I don't see any benefit to using BBM as opposed to an opensource product such as Matrix
