Actually the prolem doesnot lie with your phone.
ok iill try to give a best solution.
1) did you call you customer care about the Sim card activation,if you Sim card is not activated you might get "INVALID SIM CARD".
2)remove and place you Sim card properly into the phone as put the lock and check whether it fits perfectly.if your misplaced it wont work
3)IF your simcard is old,then its the problem with the sim card,try replace a new one.

i say its not the problem with you phone as long as your phone's menu,keypad,camera etc etc are working fine..

N73 invalid sim


HI

I too has the same problem.

There can be to problems

1.either with the corrupted sim
If that is the case ask for a duplicate one

2. Or due to the sim card slot of n73
(mine was this case)

this can be solved by just re inserting the sim card and pressing slightly for a short time and switch on the phone.


or

the best way is

2nd one:


if the phone is under warranty show it to a near nokia service centre and they will fix it.
if not under warranty, a small charge will be taken from you


3rdly
if you tried to flash n73 it will pop up

and depending on the lock status and logs the solution depends.( in the case of flashing)

better go fo the 2nd one

hope this will help you.

Invalid sim


That's cause your phone , you buy bundle with sim card, so provider protect phone to use sim by other provider, or you ever set phones password to use sim, if nothing like that go to service center to solved your problem.
