I purchased an iphone 4 copy and my phone is showing can not register invalid sim problem

Your cellular provider has to have the phone you are using on file so that the network will recognize your sim card. If you have AT&T you can log onto your account and change it yourself. You can also call and simply say it won't recognize my sim card, they should be able to indicate the phone you are using and it should then register on the network.

My phone keeps saying invalid u sim on every sim i put in it on 3 and wont pick up any network

Is this a new phone? If so, make sure you are putting the sim card in the correct way (some phones are tricky). If you are attempting to add a sim card from a different network than what the phone is registered through, it often won't work unless you jailbreak it (a whole different solution). This is not legal, and often won't give you full capability of the phone. Finally, if you think it is a problem with the sim card, it might be rusty or dirty. Try lightly cleaning it with a soft eraser from a pencil. Good luck!
