There is more than an issue to cause this. 1st that some iphones are locked on a specific operators, with a contract for one or couple of years. after end of contract you can unlock the iphone at the operator and can use any sim card. 2nd the sim card it self may be damaged & cannot be read by iphone, please try it in another phone and see if it is working.
To know if your iphone is officially locked/unlocked by the model number, you can google it.

A simple way to check is by inserting other network's simcards with the iPhone 4 and if it works without any problem then the iPhone is unlocked...if it shows any error messages like "Invalid sim"or "Error sim" then the phone is locked with a particular network.To remove the network lock you can approach and remove the network lock permanently using their remote unlock service.If you have any doubt with what network the mobile is locked can use their contact us form to get the respective details.
