SIM backup is a system that allows a user to save, store and retrieve the contents of his SIM card from a safe, third-party location. The contents of the SIM card will remain at the location until they are retrieved by the user. SIM backup is especially helpful for those users who wish to avoid losing their SIM card contents if they happen to misplace or damage their phones.
When users think of SIM card content, contact names and phone numbers are usually the first things that come to mind. A SIM backup can help save and store more information than names and numbers. Any compatible content, like texts, can be backed up. It should be noted that any content that is intended to be backed up needs to be saved to the physical SIM card. Phone numbers that are simply stored on a phone may not be able to be retrieved and saved.
Many companies offer SIM backup service. However, SIM backup is considered an extra option and will have fees attached to it. Companies may charge per backup or they can charge an annual fee, such as with a regular subscription. SIM backups can be performed within minutes. Users will have to provide the physical SIM card to the service company so that the company can access the data on it. While the SIM backup is being performed, the user will not be able to receive or make calls.
Once a user finds an occasion that requires access to the saved data, he may revisit the company and ask for access. However, some companies may also give secure, online access to customers. Users who want access to their data may simply log on to a website using a user name and password and retrieve their information any time they wish. Users may also be given the ability to manually update accounts by adding contacts and phone numbers on the website.
If a SIM card is lost, damaged or stolen, a user may have to buy a replacement. In these cases, restoration of content and contacts can be done at the company's site. However, technology makes it possible for the average user to restore data to his phone from the SIM backup website. Authentication may be necessary, but once identity has been established, contacts can be transferred to the new phone within minutes.
