Some SIM card only deals for cell phones are available from USwitch.com and CarPhoneWarehouse.com. Additional deals for SIM cards can be found on MoneySuperMarket.com. All three sites allow users to compare a variety of different SIM cards.
SIM card only deals are cell phone plan options in which a buyer purchases only the SIM card inserted into a phone rather than an entirely new phone. Purchasing a SIM card only allows users to get a better deal on their phone plan or switch to a new plan that is less expensive or better suited to what they need without losing data stored on their old phone
