SIM card stands for Subscriber Identity Module or Subscriber Identification Module. They are inserted into every phone to store the International Mobile Subscriber Identity (IMSI) number which is used to identify a phone user.

Every SIM card has its own unique number and can be used to store hundreds of data including names, phone numbers, addresses and messages. Our contacts and text messages are some of the most important data on our mobile phones, and they can be stored on our SIM cards.

When switching to another phone, most people are very interested in how to clone a SIM card unto their newer phone, especially in case they cannot just insert the SIM card in the new phone. There are many ways to achieve this. This article explains a few of them.

What types of data are stored on your SIM card?

A SIM card typically has between 8KB to 256KB of data storage capacity. This can be used to store contacts, call logs, SMS/MMS, application data or system logs and other information.

Most SIM cards automatically store a number of SMS messages and phone book contacts. Contacts are usually stored in simple mode, consisting of just names and numbers. The number of contacts and messages that are stored depends on the type of SIM cards. Earlier SIM card models could save as little as 5 messages and 20 contacts, but most modern SIM cards can store contacts as much as 250.

All these make it even more important to be able to clone the data off your SIM card when you buy a new phone.
