Hi @Nehal B. Shah , 

First of all, welcome to our Community!

The subscription with the rate of 10 euros per month includes unlimited calling.
If you still want to choose a lower or higher bundle, you can add the unlimited calling bundle separately to the subscription, this for only €1.50 extra per month! You can check this option during the ordering process.

You can find more information about our bundles and rates on our website. 

Regards, 

Lisa
