SIM Toolkit & Network info

What this SIM and network information app covers

This is a utility for reading the details of the SIM card in a phone, the cellular network it connects to, and the device itself. The developer presents it as a single place for that information rather than a set of separate screens.

It is aimed at people who want to check their SIM, network, device or battery figures without assembling them from different parts of the system.

Reading SIM card and voicemail details

The app shows the country the SIM belongs to, the network operator name, the card's serial number and the subscriber ID. These are the fields you would check to confirm which carrier a card is registered with.

It also lists the voicemail name and number set on the SIM, so the voicemail configuration can be read in the same place.

Checking the cellular network and device specs

The listing says the app covers cellular network information on 2G, 3G and 4G. The developer describes it as giving detail on the cell network as well as the SIM itself.

For the device, it reports the manufacturer, model, Android version and build ID. Those are the values needed when identifying a phone's exact software build or comparing it with another device.

Battery health, status and charging readings

The battery section monitors battery health and reports the current status, the temperature and the charging details. Temperature and charging readings are the figures most often checked when a phone runs warm or charges slowly.

These readings sit alongside the SIM and device information, so the battery can be checked without leaving the app.

Contact names and numbers in the same app

The app also includes contact information, meaning the names and phone numbers stored on the device. It is one of the five parts the developer lists, and it sits alongside the SIM, network, device and battery details rather than replacing the phone's own contacts.
