Does my phone need to be unlocked?
Your phone does need to be unlocked to use a SIM deal. Most 3 phones are unlocked by default, as are phones sold by Carphone Warehouse and giffgaff (double check, but most are…).

Is SIMO much cheaper than a contract?
SIMO deals are a lot cheaper than mobile phone contracts for two reasons. Phone contracts are essentially a loan for the value of your chosen handset, plus an airtime contract. SIM Only plans concentrate on just the airtime and competition in that market means prices are kept low, with regular special offers and time limited deals.
Can I keep my old number?
Generally, yes. If you are moving from another network you need to request a PAC code and provide it to Three who will use it to transfer your number to your new contract.
