Anytime calls to UK mobiles and 0845 / 0870 were only available on £15/month package before. Now it is included in £8/Talk unlimited
If anyone on usual Talk unlimited bundle, call customer service now and they will upgrade this to existing package for free. No extra contracts or charges if you are paying £8/month less any loyalty discounts.
Hope this helps someone, as I was charged to call 0845 until now and now with a phone call to customer service this is included. UK mobile calling bonus.
