Now they've taken over the Telewest / NTL networks, Virgin are now advertising their "Talk Anywhere" service.

One example is
For £20 per month you get line rental which is normally about £11 and 200 mins of calls to ,,,,,,,,,
"   * Landline UK numbers (they usually start with 01 and 02)
   * Mobile phones (starting with 07)
   * Non-geographic numbers (starting 08 except for 0800)
   * International landlines and international mobiles (all countries)
   * Dial-up internet numbers"

Obviously the more astute, and those with common sense, will continue to use dial through, unless you're a Samoan mobile.

Aye, saw that afore it was publicised and didn't wanna bother people with it. Frankly its a waste of money, for only what, 200 minutes for £9? Only useful thing I can think of, is its 4.5p a minute to those numbers allowed. I only see that useful for daytime mobile calls.

They (Virgin), will have better packages on the way for sure, so Id just stick to your familiar call provider for now.
