Memory
Your phone must have enough memory to support the file size of the download (listed at the top of the page). The installation may require slightly more memory than indicated. Please check that you'll have some additional memory left.

Internet
Your phone's mobile Internet settings must be enabled in order to download this file. If they aren't, or if you're unsure, you can go to the Phone set-up service to set up mobile Internet for your phone.

HTTP settings
You can connect to the Internet via WAP or HTTP. In most cases, connecting via WAP will work fine, but for some larger files your phone may need to be configured to connect via HTTP. To find the file size above which HTTP settings are required, and to ensure you have HTTP settings when you need them, you'll need to contact your operator.
