mg5077 Interesting, never knew that.
While I've used the Alcatel Smart Flip from Cricket and At&t and never had this issue.
So this is basically made to be used for an At&t Sim or for someone that doesn't care for a 10 second delay for outbound and incoming phone calls. Or 2g with no picture messages on TMobile, but no delay.
Interesting that there's no fix.
Always heard about these phones that were avlb for T-Mobile, decided to finally try it. Was never told they won't work properly.
