Sim Card Minutes
Sim only deals are much like pay monthly mobile phone plans. The only difference is that you will not get a free handset and you will not sign a lengthy contract. Much like pay monthly plans, sim deals also come with sim free minutes. Compared to pay monthly deals, however, you get more sim card minutes.
The number of sim minutes you get depends on the price of your sim deal. For cheaper deals, the number of minutes is minimal. If you want more sim free minutes, be ready to spend more every month.
