Hi, 
I have a HTC EVO 4G, the MEID has been registered on Reliance, and the phone activated thru *228. 
I can dial out, receive calls, but every call gets disconnected after 2 secs or so. 
As I understand the issue can be fixed by adding the A-key. 
I got the A-key, but I don't know how I should key it in to the phone. 
##2539# is not working on the phone. I don't see a a-key option in any of the other menus. 
Is there some other way? 
The phone is not rooted yet, is this required to add the a-key? 
I have QPST installed, and can get CDMA workshop if needed. 
Thanks, 
Sameer
