I bought a new phone yesterday to replace an existing one. When I try to place a call I get a message that says "You are roaming, to call your mobile carrier or any other phone number, purchase a calling pin by pressing 1 now. To place a collect call to a mobile phone or a landline phone dial 2 now" and I can not receive calls. However, in the network settings it says I am "Not Roaming". In addition, I can send and receive texts and access Data using the phone.
