I have an international plan with Sprint, and have dialed internationally before I bought my Treo, but haven't been able to ever since. When I dial, it gets up to the "active" screen, the timer starts counting until about 2 seconds, then it goes back to the dialpad screen as if nothing ever happened. It shows on my outgoing call list too. Anyone know if something needs to be done to the Treo to allow intl dialing?
