[QUOTE=ihpwf12;4318515]What kind of SIM was there in the phone? Was it a PTCL SIM?
If you take the PTCL SIM out of it, can you put it in some other phone and use the 3G network the same way?[/QUOTE
Set comes with nothing pre installed except evo 3.1 mbps wireless.
There are two options for network hence two jackets are therein .
One for gsm sim,you may use any of the network operator sim in this jacket like ufone,mobilink,telenor,zong and warid.
Second jacket is for cdma sim which comes installed in ptcl Vfone.
So your are supposed to have both gsm and cdma networks work together on this set,if you wish so.
I personally leave my cdma jacket empty because i do not need Vfone on it.
