Hi @Rbj, welcome back! You can call from anywhere in the world to anywhere in the world. However, be aware of the costs.

For India we have 2 bundles available, the Voordeel 100 (€9,99) and the Voordeel 500 (€39,99). These give you 100 or 500 units to spend on MB's, minutes or sending texts. The bundles are only valid for calling to the Netherlands or other EU countries. The bundles will also be used if you are receiving a call while in India. 

For calling to non-EU countries, you will pay by the minute. How much that is depends on where you're calling to. Each country has its own tariff, and the highest of the two will be used. The tariff for India is €2 per minute for a call and €0,30 per text sent. Receiving texts is free. So this will be the minimum amount you pay when you call from India to a non-EU country.

 The bundles can be activated through the MijnKPN (web or app version) or by texting VOORDEEL 100 AAN to 1266 for the 100 bundle and texting VOORDEEL 500 AAN to 1266 for the 500 bundle. If a bundle has been fully used, you can activate another one.

Thanks a lot for quick reply.
