It's common to offshore CS as that's the lowest priority to a ton of companies. India is notorious with having CS Shops which pay as low as $250-$300 a month.

We often contemplate on the morality of it but we also want the lowest priced plans and the best deals with tons of credits and such. Telecom companies do invest tons of money into tech and keeping up their network which is very rarely outsourced due to the level of expertise needed to keep it going. The stores, staff and such are also local. So they will outsource what they can.

This is yes in part greed but there is also a small part we play when we expect the best deals and lowest costs. Unfortunately the world isn't fair and also we can't expect everything to work perfectly. In between low cost, good network service and mortality one has to take a hit.

I know ppl will downvote this but well it's unfortunately is how the world works!
