OT Three Talk & Text 600 Tarriff

Sorry to ask but got no documentation with the phone.

1- How much is it to call 0845 and 0870 numbers on this tariff?? or is it
included in the minutes.

2- Can you send and receive pictures or videos with the inclusive texts or
are they extra- if so how much??

3- To end the contract how much notice do you have to give??

4 - What can you download free for 30 days- everything is excluded on my
phone - or is it that I am not in the 3G coverage area?? Can I download the
rent for 3 days games ??( I know the buy games are excluded) - I can not see
any pop videos to download??

Thanks

Nigel
