The mobile phone market never ceases to amaze me with its constant evolution. Recently, while doing my regular banking check, I stumbled upon something that made me do a double-take - a $4 monthly mobile plan through CommBank’s More rewards program. Yes, you read that right - four dollars.

Living in a time where most decent mobile plans cost upwards of $30-40 per month, finding a 12GB plan at this price point feels like discovering a hidden cheat code in a video game. The catch? You need to be a CommBank customer, and from what I’ve gathered, the level of discount varies based on your relationship with the bank.
