Need to be able to receive calls from USA to Cell phone in Pak for my posible visit..

[Ghareeb_Da_Baal]

Ok so I havent been back in 5 years.
I still need to be able to take calls from
my clients as I am in realstate related
line of work & cant afford to be absent
for more than a 2 days!

I have a google voice number that rings on
my home phone & cell at the same time
in US.

I am looking to be able to get my incoming calls to
my google voice number to ring on a cell phone
in lahore.

Any suggestions? I did look at a forwarding service butit is like
0.32 cents per minute to cell phone.

I am not looking for a voip/skype solution as that wont be very practical plus I do have magic jack that i rarely use.

Speaking of magic jack, can I even use it in Lahore?
I ve heard that the ports used by MJ are typcally blocked
in PAK by most ISP's. I ve heard they also have wimax also but
I know for a fact that voip will suck over wimax signal.

I can always use MJ to make calls to US if needed provided it works.

Thanks!
