ZALMAN: the company I work for is on the old telecom network with no intentions to initially change to XT
is there any way possible for me to run a xt work phone
or would the only way to be by dirverting to the xt sim which would incurr extra cost?
Correct, the only way to do this would be to purchase a new xt device with say a prepay sim then set an immediate divert from your cdma phone to your new xt number, but then of course you can't make calls out without topping up, so long story short, no. If you want an XT phone, just switch to the network!
