If I be to call on India, would it be hard/troublesome to call in China or Nepal?

If someone could enlighten me on this (the border crossing situation, whether visas are required, etc), it would be greatly appreciated!

Answers: China will require visas from country of your derivation. Nepal will not need visas if you travel on Indian passport

u dont necessitate visa to go to nepal frm india.. very well but only if u r indian.. no notion abt china..
