SIM is an acronym for Subscriber Identity Module and the Sim card is used for to identify each phone. Each card has a unique key that identifies the subscriber on a phone to the telephone network. The unique key is a mixture of numbers that are encrypted within the gold colored metal on the tip of the card. That is the beauty of the Sim only deal; you can Simply move your card from one phone to another without any loss of service. Your mobile network is only interested in the Sim – not the phone that you are using.
Have you noticed that no one seems to remember phone numbers now days? Not surprising really, because they are now too long and complex to remember. When you ask for a new number, you store it on your phone or get them to text you and let the phone store it on your behalf. If you want to phone someone then the phone automatically looks up Joe or Jill for you. This is because your pay as you go SIM card stores all this information. So when you change phone with your deal all your vital contact information goes with you.
Well your Sim card will also save all your text messages – those you have sent or received. Modern cards can typically store about 300 of them – so you can save many memories. Just make sure that you save to the card and not save to your phone. So next time you start a long conversation with your long lost friend you can save all the texts with the full knowledge that your Sim only contract lets you keep these texts as you move from phone to phone.
Well, what about all those photographs and tunes that you have so devotedly collected over time? Those will all save on your pay monthly sim only deal card in your deal.

When you move your contract over to another phone, which is so easy with a Sim only deal they all go with you. Makes setting up your new phone, the fun thing it is meant to be.
