You have kept a for loop like this:

for(var i=0; i<$scope.phones.length; i++)

here you are trying to access the length of $scope.phones variable. But you have defined $scope.phones inside the success callback of your api call. But your api calls are all failing. therefore success callback are never getting called and therefore $scope.phones is always undefined. Thus you are getting error that `cannot read length of undefined'.
