When I power my phone off then back on it will say insert SIMcard...but the sim card is already in the phone. At first, icould turn off then on a couple of times and it would finlly see it. Now it doesn't even come on...just insert simcard. My sim card works in other phones, so i don't think its the card causing the problem. Any suggestions?

This can really be only one of two problems. Either the phone SIM slot has been damaged or the SIM card has failed and needs replacement. It is obviously easier to try a fresh new SIM card. You need to call or go to your cell phone carrier's store and request a replacement SIM card. If the same message comes up with a new SIM, your phone needs servicing or replacement.
Remove the SIM card from your phone, clean the contact point (the copper part) of the SIMCARD with a rubber eraser then insert the SIM card back again to your phone.
If SIM card is still failing, then it is already defective. Get a new SIM card.
If your phone displays the 'Insert correct simcard' then your phone is currently locked to particular network. You need to unlock to use it with other network. There can be many ways to Unlock your phone. As far as i know unlocking by codes is the simple and safe way. I will suggest the website Unlock-zone.com which is doing good service and they were recommended highly in the cell phone forums. I used them to unlock my cell phone. contacted them and within 30 mins i had my unlock code and my phone was unlocked. Hope this helps.
Turn off the phone.Take the battery and Sim Card out.Make sure there is no dust or dirt of where the Sim Card goes.Blow air (from your mouth) of where the Sim Card goes.Sometimes rubbing a soft pencil eraser on the Sim Card contact points can help. Then place the Sim Card back in the phone.Make sure it is in the right position; copper contacts facing downward.Put the battery back in your phone.Turn it on, and see if the smartchip rejected goes away. If not you may need to contact your Phone Provider’s Tech Support to troubleshoot and confirm that you may need a PUK reset code to register or you may need a new Sim Card, as they do fail from time to time.
