Currently, the only phone I have is my iPhone, which is on Vodafone Red Essentials.

I've recently become part of a long-term project that makes use of the Spark audio conferencing service, 083-033. This is the number where it's free to the caller, and the organisation pays.

I've already been able to establish that Vodafone considers this a special number, so unlimited minutes don't apply here.

Can anyone tell me:

1. Do Spark and Skinny mobile let you call this number as part of an unlimited minute package?

and

2. If I were to get a 2Talk number with their local $9.95 service, would this be considered a local/free call?

Thanks.
