This year was excellent for WP8 users as most of the apps joined the platform. Some are scheduled to launch in coming days. Today Nokia launched another app called SIM Applications on the WP Store. This app may come handy to those users who use built-in SIM features.
Now those users don’t have to go through the hassle - Setting > Mobile Network > Sim Applications anymore to access the operator services. Just install this app and off you go with it.
