I'm on Verizon and regularly use the wireless hotspot. I've noticed most times when starting the hotspot it will get stuck on a pop-up screen which reads 'checking subscription status, please wait.' When this happens, I need to reboot the phone. After a reboot, the hot spot will start almost instantly. I'm on a data plan that includes the hotspot so this is not an issue of not having that setup on my account. Have any of you seen that too?
