Retailers of 2degrees have already begun providing SIM cards and devices to consumers, even though there is still one day to go before the company reveals all.

But it should be noted that this move has been taken since the 'big secret' had already been made public by Progressive, which owns a range of supermarkets, via its online shopping website.

It should be noted that $2 SIM cards online are being offered by the website, with $2 already loaded onto the card, while Warehouse Stationary is already offering nine prepay mobile devices and SIM cards.

Furthermore, the Warehouse Stationary website also says a little more about 2degrees' offers and plans.

To-ups are being offered by the company in store for $20 to $100 or any $10 increment in between.

The website says: "All top ups are magic, meaning that customers will get free stuff when they top-up." Warehouse Stationary will be offering $2 SIM cards with $2 already loaded onto the card, similar to Progressive. No contracts would be offered by 2degrees.

However, tomorrow everything will be made public at a soft media launch in Auckland.
