I have the same issue since move from mobilicity. People from other carrier always complain of call-drop first time even before connect . It goes straight to voice mail.  I tried diffeeent phone ... same issue. 

Same here. Hit n miss. Calls wont even connect.. Texts wont go thru etc.

Tried new sim but no go.  Tried on 3 diff phones and no go.  Not sure what else to try.

I too called every week until they told me nothing could be done.  I replaced the sim card.  And then they wanted me to replace my phone.  Seriously?  It just so happened that my phone broke in the meantime and I had to buy new one.  That one works.  But according to them it was all my fault - even though it all broke immediately after they switched to Chatr.

I have the same problem. I've been calling customer service every week and I hear the same answers. Apparently tickets were created to fix the problem but nothing improved. I never dropped a call when I was with mobilicity. It's very frustrating
