Jammydoger12345 , just about every conceivable way

I’ve been using this app for work for 12+ months now. Contacts keep decoupling; you can’t delete text messages as a thread; often just hangs up and frequent issues with texts having lengthy delays being delivered. Seriously look elsewhere for a dual phone number app; this one is pants and developer responsiveness is nearly zero.

Business caller id

Really like the new update which is showing me the names of my business contacts when they call and also shows me that the call is to my business number

Mr Bond Man ,


Want to destroy the functionality of a phone? Install this. Your idiot IT security team will insist on this and won’t care that you literally have to press the star key once you’ve found it to answer a call. Enter a passcode to make a call? Maybe twice. Unbelievably poor user experience. The worst.
