The sim card is inserted above the battery which is located on the back of the phone. The attached photo shows what you will see under the battery cover. First, turn the phone off. To remove the battery, start by removing the battery cover which is the back cover of the phone. Press on the back cover in the center next to the camera and pull the cover down towards the bottom of the phone. The cover should slide off. Slide the sim card, face down with the "notch" on the top right side of the sim up underneath the small metal receptacle designed for the sim card. If you do not see the receptacle, look for an etching of the sim card on the phone that is above and to the right of the sim card receptacle.

The answer is simple...The phone is network locked...either contact the UK Vodafone customer care or contact a mobile shop where you can get it unlocked then you can use the phone in any country...I got my unlocked in INDIA for Rs. 800 that's about $20.That's all you can do because every phone has a different code...so your's one is also unique.

Take the SIM-card out. It's important that the SIM card IS NOT in the phone, during the following steps!!

Turn on your phone without the SIM-card

Enter *2767*3855#

Insert the new SIM-card, and see if it is unlocked
