What is the Sim Info App?
The Sim Info app is a free Android application built specifically for Pakistani mobile users. It brings together everything you need to verify, check, and manage SIM information in one fast, lightweight tool — without opening a browser, without creating an account, and without paying anything.
Every feature in the app is designed around how Pakistanis actually use their phones. You get SIM owner lookup by mobile number, CNIC-based SIM checking, a network prefix identifier, a full library of USSD codes for all five networks, and a device health checker — all in one place, launching in under one second.
The SIM owner details app works on all Android devices running version 5.0 and above. It is optimised for low-end devices and takes up minimal storage space so it runs smoothly even on basic smartphones.
What Can You Do With the Sim Info App?
SIM Owner Lookup
Enter any Pakistani mobile number and instantly retrieve the ownership details tied to that number in PTA’s database. Works for Jazz, Zong, Telenor, Ufone, and SCO numbers.
CNIC-Based SIM Check
Enter a 13-digit CNIC number and see every SIM registered under that identity across all five networks. Essential for catching unauthorized registrations before they cause damage.
Network Prefix Finder
Not sure which network a number belongs to? Enter the first four digits and the app identifies the operator instantly — no internet connection required for this feature.
USSD Code Library
A complete, up-to-date library of USSD shortcut codes for balance checks, data bundles, call minutes, and account management across Jazz, Zong, Telenor, Ufone, and SCO. No more Googling codes every time.
Device Info Checker
Check your phone’s RAM status, battery health, storage usage, and hardware details in real time. Useful for knowing when your device needs attention.
Offline Support
The prefix finder and USSD code library work fully offline. No data connection needed for these features — ideal for areas with weak signal.

How to Use the Sim Info App
To check by mobile number
Open the app and tap the mobile number tab. Enter the number without the leading zero — for example, type 3001234567 instead of 03001234567. Tap Search. The app will display the registered owner details, network operator, and SIM status within seconds.
To check by CNIC
Tap the CNIC tab. Enter your 13-digit CNIC number without dashes. Tap Search. The app will show every SIM registered under that CNIC across all networks, along with their current status.
To find a network prefix
Tap the Prefix Finder tab. Enter the first four digits of any Pakistani number. The app instantly shows which operator owns that prefix range. This works offline.
To find a USSD code
Tap the Codes tab. Select your network from the list. Browse or search for the specific code you need — balance check, data bundle, call package, or anything else.
App vs Website — Which Should You Use?
Both our web tool and the Sim Info app give you the same core SIM lookup results. The difference is in how and when you use them.
| Situation | Use |
|---|---|
| Quick lookup on the go | App |
| No internet available | App (prefix + codes work offline) |
| Need USSD codes fast | App |
| Using a desktop or laptop | Website |
| Sharing results or printing | Website |
| First time checking | Either |
The app is faster for repeated daily use. The website is better when you need to read detailed guides, check multiple methods, or access the page from a computer.
Supported Networks
The Sim Info app covers all five Pakistani mobile networks.
| Network | Prefixes | Helpline |
|---|---|---|
| Jazz | 0300–0305, 0320–0325 | 111 |
| Zong | 0310–0319 | 310 |
| Telenor | 0340–0349 | 345 |
| Ufone | 0330–0337 | 333 |
| SCO | 050x | — |
