Free sim cards are a great way to switch and swap between the most competitive tariffs available for your mobile phone.
What many people don’t realise is that there are many plans that the mobile operators don’t heavily publicise that can save them a lot of money. If you think about it, it makes sense that they’ll put most of their advertising budget into the packages that are most profitable, doesn’t it?
By doing a little research, you can find a better deal, or even several deals that you can use interchangeably. You don’t even need multiple handsets to do that – if you can cope with the hassle just switch over the sim cards as required!
