My dad just bought me a razr from ebay. It has no company branding on it. It was from Hong Kong. Everything works except for when i received a sound file or picture it tries to download it but after a few minutes it says it can't. I've googled it and it seems a lot of unlocked phones from ebay are like this. I have t-mobile but could only find ways to fix it for at&t. Can anyone help me?
