Why are SIM Contracts more affordable?

SIM contracts are a great choice for customers who want to save on their mobile bills. By paying for your usage only (rather than the usage plus the monthly cost of a phone) customers can significantly reduce their costs. Choosing a longer contract term such as 24 months is a way to further lower your costs but you usually must keep the contract for the full term.

1-Month SIM Deals

1-month contracts can be much more flexible since you can swap to another SIM after 30-31 days by contacting the network or switching to a new network altogether. Networks which specifically provide rolling contracts such as Smarty and Voxi also have the benefit of requiring zero credit checks in order to purchase.
