As the name suggests, with SIM-only mobile phone deals you are only provided with a SIM card and not a mobile phone handset. Mobile network providers therefore save money from this and are able to pass the savings directly on to you (the customer) by offering cheaper low cost contracts with more cross network talktime minutes, text messages and monthly data usage allowance.You will therefore need to have your own mobile phone handset or will need to purchase a phone separately (if you don’t have one). The contract length with SIM price plans vary from 1 month to 12 months, with the 12 months SIM card tariffs offering better deals. The 1 month (often referred to as 30 day SIM card only) however work out to be better deals in comparison to standard long term mobile phone contracts.If you already have a handset locked to a particular network operator, we recommend that you either get the phone unlocked or you choose a SIM contract provided by the network that your handset is locked to. Once you have placed your order the mobile networks tend to have your new SIM delivered to you the next day (depending on the time of day you place your order).
