Hi,
Nokia 1616 is a GSM mobile, I think you have inserted a CDMA sim which 1616 don't support, In such case the message 'sim not valid' shows.

it may be network lock i think please call the service provider to fix this problem.

IF THE PHONE CAME BUNDLED WITH THE SIM THEN IT WILL NOT ACCEPT ANY OTHER SIM THAN AIRCEL, THAT MEANS TO SAY THE PHONE IS LOCKED.THE BEST WAY TO UNLOCK THE PHONE IS TO GET IT FLASHED BY A PHONE MECHANIC.
