It happens to the best of us. You get a new SIM card, pop it into your phone, and then... blank. Someone asks for your number, and you have no idea what it is. I remember getting my FNB SIM and being so excited about the deals, but for the first week, I had to carry around the little card it came in just to remember my own number! It was a bit embarrassing, to be honest.

Luckily, checking your number on an FNB SIM card is super easy. The quickest way to check your FNB number is by dialing the USSD code *121*3*4# on your phone. Your number will then pop up on your screen.

How to Check Your FNB Number

Finding your number is a simple process that only takes a few seconds. Here is a step-by-step guide to make it even easier for you.

1. Open the phone app on your smartphone, the same one you use to make calls.

2. Dial the code *121*3*4# into the keypad.

3. Press the call button.

4. A message will appear on your screen showing you your FNB cell phone number.

I once had to give my number to a new friend at a noisy concert, and I just couldn't remember it over the music. I quickly dialed the code, showed them my screen, and they saved my number. It saved me from shouting over the loud bass!

Other Useful FNB SIM Codes

While you're saving your own number, it's a good idea to know a few other handy codes for your FNB SIM. You never know when you might need them.

• To check your airtime balance: Dial *310#
• To check your data balance: Dial *323#

Knowing these codes can save you a lot of time and hassle. Speaking of airtime, if you're ever running low, it's good to know what airtime you should buy for the FNB SIM.

Running out of airtime can be a pain, but did you know you can earn free airtime just by using your phone? With the Points Castle app, I complete short surveys and play games to earn points. I then redeem those points for airtime vouchers. It's a great way to top up my phone without spending extra cash.
