Reliance & Aircel SMS blocked on Airtel
Both Reliance and Aircel have a different stance. They say, Airtel being the largest telecom operator in India (it's even 4th largest in the world) is using the pressure techniques to make them pay more for the SMS termination charges. The companies allege that Airtel is misusing their dominance in the market totally ignoring their customers.
I'm sure we've several CEans who're on these networks. If you're facing inconvenience with sending messages there's an alternative! Use 'WhatsApp'.
This free app is available on most of the mobile platforms. Plus I'm quite sure that most of your contact list will already be using this app (you can see who's using it once you register on WhatsApp). You will pay for just one message (the regular data charges apply) but it will get delivered to all your WhatsApp contacts all over the world.
