They are far and above the best value of all the providers, their signal strength is fine these days. I have two mobile phones and a mobile dongle with them all on contract for 3 years so I've had a fair chance to test them out. They've always been excellent. Good customer service available all times of the day, it does seem to be in India but the staff are always helpful and speak good english. For the value I can hardly complain, I also have the very latest phones.
