Maybe permission in AndroidManifest.xml is required? On TelephoneManeger
website is information: "Note that acess to some telephony information is
permission-protected. Your application cannot access the protected
information unless it has the appropriate permissions declared in its
manifest file. Where permissions apply, they are noted in the the methods
through which you access the protected information."
