Secondly this feature is only available for windows phone which has SD card.

IMO the big idea is to get the app to your phone, so if in your area data connectivity is a problem, you still can get the apps installed. So if, the App will be checked with the store anyways, even just for version check, what is the big idea behind this feature. A paid which has a trial version will be instantly available but if the paid app has no trial, you will have to first buy it and then use it.

Now once verified with the store, any free app or game can be used immediately.

The above steps makes it clear that you need to have Internet Connection before installing the app.

The XAP file which you try to install from SD card gets verified with Windows Phone store to check if its the latest version else it will be marked as incompatible.

Tap to install and it will appear in its respective place.

This will list down all the XAP files or the apps available.

Next copy this XAP file to your SD or the media card.

So anybody can do it for you, and carry it for you even on a USB. Best part is you are not asked to sign in to your Microsoft account before downloading it.

This will start downloading the xap file.

Next Scroll down a bit, and look for a link which says “Download and install manually”, click on it.

First Go to > Apps + Game > Search, and Select the app you want to download.

Though SD card was supported in some Windows Phone 7.5 users but not for installing apps. Note : This is limited to Windows Phone 8 users. This feature is an enhancement for users who have difficulty in downloading the app to the phone either because the app is too big and you don’t have a wifi network around or your phone does not have mobile network connection at that moment.

This feature allows you to download and sideload / install Windows Phone Apps using the SD or the media card ( Sorry Lumia 920 Users). Windows Blog not only announced the availability of Windows Phone Web Store in 37 new countries, they also introduced a new feature in Windows Phone 8 Web store.
