Hello everyone,

So me and one of my friend are traveling to Germany for around a month for student exchange programmes of the University which includes a course. As an Indian,I would really like to know if there's any need to buy German Sim Card for the mobile phone for a month as I'll require something for calling there for the locals around,or should I continue with my Indian Sim??

Also if any other suggestion and things which I should do/avoid, please feel free to let me know during our 1 month travel here.
