I got a sim card from bpl. Now one fine day my younger brother while playing a game on my cell decided to fool around with the pin number. What he did was he entered the pin number incorrectly thrice & now the sim card is rejected. I tried calling up bpl cutomer care from my landline but there is absolutely no response. Bpl mobile considers itself the best in cutomer care in the country. I guess if there is no cutomer service that's how u become the best.
