Min Saga — The Saga Mobil customer app

What the app does, how it works behind the scenes, and what you can do with it.

Watch the app in action

What is Min Saga?

Min Saga (Norwegian for “My Saga”) is the customer app for Saga Mobil AS. It lets you manage your mobile subscription without calling customer service — check data usage, buy extra datapacks, turn products on or off, and manage SIM cards, all from your phone.

The experience is built around an aurora-themed visual design: deep forest-green backgrounds with flowing northern-lights-style data visualizations, so usage information feels clear and engaging rather than like a dry utility bill.

A built-in admin panel (restricted to authorised staff) supports configuration without releasing a new app version: product visibility, featured items, plan-change rules, support impersonation, audit logging, and more.

How it works — the big picture

When you open Min Saga on your phone, the app talks securely to Saga Mobil’s API — a Go service running in Docker on our servers. The API sits between you and Saga Mobil’s billing platform (eRate), handling login, security, and Vipps payments so your subscription data stays protected.

The iOS and Android apps are built with Capacitor, which packages the same interface into a native app for each platform while keeping one shared codebase.

The app itself is installed from the App Store or Google Play. All subscription actions go through the API, which reads and updates your account via eRate and handles payments through Vipps.

Design and accessibility

• Dark-first UI on deep forest green with aurora accent colours
• Mobile-first — thumb-friendly navigation, bottom tabs, and safe-area support on notched phones
• Accessible contrast for text and buttons in both light and dark use
• Three languages — Norwegian, English, and Northern Sámi

In short

Min Saga is your Saga Mobil pocket assistant: see how much data you have left, top up with Vipps, manage SIM cards and products, and — for families and businesses — oversee every number on the account. Aurora visuals, Norwegian roots, and a secure path through Saga Mobil’s own API to eRate and Vipps.
