I hope someone here can help me, because I am at a loss. I just got my BB 8700 today and have been successful in setting up the internet and inserting new contacts. I didn't have a data plan, got one, before that I was able to make calls. I have the new SIM card in and can get online and message people, but when i try to call them or my voicemail, the phone makes a beep and the call cuts off. Any ideas???
