[Resolved]  Nokia — Always displaying ' SIM CARD NOT VALID' & phone switching off on its own despite having full battery.

After 6 months o[censored]sing Nokia 7610, the phone started switching off on its own & after switching on, it displayed as 'SIM CARD NOT VALID'. I went with the complaint to Nokia care, they updated the phone software & the problem was solved. After a month again the same problem surfaced. I went with the phone to Nokia care & to my astonishment they told me that my warranty has already expired, . According to the purchase date my warranty would expire on 24 dec 08 but according to them, the phone was purchased by the showroom on oct'08 & any repair work if done would be chargeable. I conveyed the same thing to Nokia priority showroom, they somehow managed to convince Nokia care to attend the complaint, but everytime, they are updating the software & problem is resurfacing after a week. They are not comming up with any permanent solution.
Eversince I have bought this phone Im not at peace with it. Im a student & firmy believed in the quality of Nokia phones, but this incident unveiled the true face of Nokia phones.I wud never advocate anyone to buy Nokia phones..made in china mobiles would be a better option.
