Ashal Shahn is a mobile application that enables users to recharge their mobile credit balance using their ID (Saudi Arabia) or without it in countries that do not require an ID for recharge. The app currently supports two countries- Saudi Arabia and Egypt, and eight telecommunications service providers- STC, Mobily, Zain, Virgin, Lebara, Vodafone Egypt, Egypt Orange, and Etisalat Egypt. Ashal Shahn is available in three languages- Arabic, English, and Hindi. The app is free, lightweight, and easy to use. It also has additional features such as checking credit balance, contacting customer service, and displaying the user's number.

To use the app, the user needs to select their preferred language, country, and service provider. The app then asks for the user's ID or residency number (for Saudi Arabia only) and the recharge card number. The user can recharge their balance directly from the app without any additional steps. The app also saves the user's ID number for future use. It is important to note that the app doesn't provide free credit balance, and users need to purchase a prepaid card from their service provider.

Overall, Ashal Shahn is a convenient and user-friendly app for recharging mobile credit balance.
