Is anyone aware of any subscription phone services or calling cards (cash or those that can be charged online) which can be used to call from Switzerland to India.

For example, in the UK there are many services which can be accessed by dialling from your landline or cellphone and offer super cheap per minute rates. It is great for those who have unlimited minutes on cellphone/landlines as you just pay the per minute tariff for the subscription service (was something like 10 pence per minute for India).

Many thanks
