I was trying to call to a phone in Brazil (Porto Alegre region) and it says that the operator code is not necessary anymore. Probably the 51 area code requires re-programming as there was a change in the law recently. Now, all the numbers with the same area code do not need the operator number (e.g. 21, 15, 14 etc). Please solve this issue.
I have unlimited monthly plan to India, and I bought this just 5 days back. It worked fine for 3 days, after that problem has started, other side people are not able to listen my voice properly(My Internet and audio settings are good, when I make test call it is fine).
And from today problem has become more serious , I could not able to call any Idea mobile.
Please look into this issue and resolve it as soon as possible.
