Siri can't call in Nepal

Hello there,

I'm from Nepal and It feels really great to use apple products and I own both iPhone 6s (iOS 10.0.2) and MacBook Air for my personal use. 🙂

I was talking to Siri and asking her to call on any Nepali numbers including the country code(+977), it always replied me "Sorry, I can't call using that number". I'm not sure if this is my mistake in saving contact numbers, but it doesn't work for any numbers within Nepal.

Can anyone help me how can I get it working or if this is the feature that is not available yet in my country?

Thanks.
