These reasons include: Package Upgrade: If you have recently upgraded your existing package to a different one that offers enhanced features or services, the new package may come with higher rental fees. Additionally, one-time charges may apply for specific services like data, voice, roaming, and other add-ons. Add-ons: If you have purchased an additional add-ons, such as extra data or minutes, this may lead to an increase in your monthly fees. New Device Purchase: If you have recently acquired a new device with Zain Installments on your package, the cost of the device will be included in your monthly bills. This can contribute to the increase in your overall fees. For further convenience, you can manage your package and services directly through the Zain app. The app allows you to make adjustments, track your usage, and explore available offers to ensure you have control over your subscription.
