About this app

Finding your phone number on the phone is not easy.

WhatIsMyNumber.io is a free app for Android and the web that will find your mobile number in seconds whenever you have a question “What is my phone number”. Just install the app on your device and tap "Detect Now" to get started. The My Number app will scan your SIM card and show you your phone number. If the phone number is not written on your SIM card, the app will give a free number you can call to detect your number using caller ID and display your phone number inside the app after you hang up.

The app is a simple way to detect and show you your phone number. It can answer all the questions about how to find out what your mobile number is, where it's stored on the device, or how to check it. You'll never have to worry about forgetting your own phone number again!

WhatIsMyNumber solves this problem by giving you an easy way to find out what your phone number is without having to ask someone else or calling your friends to find out. It's simple, fast, and free!

Why would you use this app:
1. Not all SIM cards have phone numbers stored inside them.
2. It's much easier to see your phone number in large numbers in the app especially for people who need glasses.
3. It's a friendlier way to show your new friends your number instead of showing them your contact list and again pointing them to the number in small letters.
4. Very simple app to use when traveling and inserting new SIM cards.

Features:
✓ Supports Dual SIM card phones.
✓ Get information about SIM card(s) in your device.
✓ Detect phone number by dialing in.
✓ One-touch to quickly show you your number.
✓ Turns your phone into a business card.
✓ Show or share your new friends your number.

The app can also display information about SIM card(s) in your device such as IMEI numbers, operator name, Network info, etc.

We know it can be hard to remember all the numbers you have, and sometimes they change. That's why we created this app - to make it easy for you to find out your own phone number. It doesn't matter if you're looking for a new SIM card or just want to check on an old one, What Is My Number will help you find your phone number in seconds.

Due to the vast number of android devices, some features might not work on every device. If you have problems with your device, contact us: support@whatismynumber.io, and will try to fix your problem in the next version. Also please write us an email if you have any problems, questions, or feature requests.

It could not read phone number off sim and does not allow one to be entered manually. I don't like dialling unknown test numbers with no guarantee its not just a scam, so please deactivate the automatic test dialler method and allow manual number input instead.

You can enter the phone number manually in settings after the timer to dial a free test phone number expires.

I like it. Works as advertised for one telephone number(sim). However, for a dual sim phone,the same telephone number shows up for each sim. Please fix it.

SIM apparently doesn't store number so had to make the free call but it worked. Confused why it needed internet access though. Nice and simple with no annoying ads.

When you make a test call we need to get a response from the webserver to get the info on what is your phone number. You're calling to a phone number, it then sends the info to our server what is your number, and the phone app then checks the website if you've made the phone call and what was your number.

What's new

We’ve updated the app to fix some crashes and make features load faster.
