Try cleaning the metal contacts with a soft cloth. That applies to the contacts inside the phone, and the ones on the card itself. If that doesn't work, it may be a fault on the card itself. In which case, contact your service provider and ask for a replacement.
You hold the action replay card in your ds (Until it says to insert game card)and turn it on and then it will say insert game card and then you insert game card
That means either your sim card is defective and it will not load the service or it means that the device is defective. Take it to the store and have them look at it
go into your multimedia files and check if it says memory card anywhwere on the list and also look carefully at the top of your screen there may be an icon that shows that a memeory card has been inserted, this only applys to some phones tho, but try tat anyway, =)
Insert the memory card into the phone, go to Menu>Fun and Apps>Files>Images>Memory Card. If the card is not formatted for the phone, it will ask you to format it, choose yes. For others that don't know about the SDHC issue. You can use up to a 4GB memory card, but it can NOT be an SDHC card, even though the phone store guy that doesn't have a clue will try and sell you an SDHC card for which you will spent lots of time trying to get to work. If it says HC on it, it will not work with this phone
It depends what it says on the memory card if it says nothing then put it into a card reader/phone connect it via usb to your pc and go to its properties
If you are getting Invalid SIM or Incorrect SIM when you insert a SIM card from a GSM provider, then it would mean that the Blackberry phone is still locked to the original carrier. You would need to unlock it first.
Throw your phone as far away from you as possible! It's about to explode!
take your game card out and blow on the botom of the back side of the game card. Then insert it again.
Well first you open it then when you do, you will see the sim card thingy thing. Then look a little to your left the it says memory card insert.
you may have some corrosion on the SIM connector terminals or on the card itself. try cleaning the terminals using a que-tip and 99% isopropyl alcohol. if that does not work you may need a replacement SIM card.
You have to get a new sim card or you put more money onto the card
Just move the memory card to its left direction!
