I just returned to Doha this morning.    I brought this morning my TATA SKY.    I just packed it along with my other usual cloths, etc in my luggage.    I traveled alone (not with family) I didnt face any issue both in Indian and in Doha customs.

I got the additional set box, installed and activated back in India.   After the installation, I got it removed and brougt only the set top box.   Now whatever package my main set top box is registered with can be seen through the additonal set top box installed in Doha too.     However we can add package or edit or remove package through online too.

It is NOT LEGAL as per the standards fixed by the TATA SKY as a manufacturer and service provider.
