Did you mean your phone shown insert sim even your sim card present on your phone?
Yes,Means,There are three possibilities to get this type of issue.
1.There may be a problem in your Sim card so try another one.
2.Check your Sim whether it's properly inserted or not
3.Your mobile is locked to particular network provider.
If your problem persists,After trying first two ways means definitely Your mobile phone is restricted by some network so try to unlock your mobile phone.For unlocking you can approach your service provider or else try to buy an unlocking service from any one of the online unlocking service provider like

Hi,

To unlock your mobile you need to get network unlock code(NUC) from current service provider via phone or go to service provider office.

While you get the Network unlock code ,the service provider customer care officer will ask for your personal details to check whether the mobile belongs to you only.If they are satisfied with your answers they will provide with the network unlock code.

Thanx
