About

Dual SIM Data Usage

Features
Read full description

A data usage tracker for people who use two SIMs (eSIMs) on one iPhone. The Settings app doesn't make it easy to see how much each SIM has used this period, or how much is left. This app records your cellular data separately for each SIM, based on which line was in use at the time. ■ Great for • Using a work SIM during the day and a personal SIM at night • Juggling two personal SIMs • Tiered plans where you want to stay in the cheaper tier but keep going over ■ Features • Usage, remaining data and days left for each SIM • Forecast for the end of the period at your current pace • Comparison with the same point last month • Monthly plans with a reset day, and plans valid for a fixed number of days (30/90/180/365) • Tiered plans (price depends on usage): see your current tier and how much more until the next one • Set a goal tier to see a daily allowance and today's usage • Count limited-time add-ons (e.g. for travel) separately • Charts for the last 7 days, 30 days and 12 months, filterable by SIM • Home Screen and Lock Screen widgets • Optional: track Wi-Fi by network (SSID) too — handy for capped pocket or travel Wi-Fi • Notifications at 80%/100%, before the next tier, and when you're on pace to exceed your goal • Match the numbers to your carrier's app ■ How it counts The app reads the iPhone's cellular data counter and adds the increase since the last count to the line that was in use. With the widget added, it counts automatically every 15–30 minutes. Usage while you switch lines between counts is estimated, so numbers may differ slightly from your carrier's. Prices are estimates — check your carrier's app or website for exact usage and charges. ■ Privacy No account needed. Records stay on this iPhone and are never sent anywhere. The app does not look at the content of your traffic or which apps you use.
