A SIM (Subscriber Identity Module) card is kind of like a key to a cellular network&#;storing vital information like your unique identification number, contacts, and other data. So, what are they exactly, what are the different types, and why do some phones not have them? We&#;ll take a closer look.
In the early days of cell phones, SIM cards could store about 20 contacts and five SMS messages&#;We've come a long way since then. First developed in by German Smart Card Maker Giesecke+Devrient for a Finnish Network provider1, the SIM card was based on guidelines provided by the European Telecommunications Standards Institute. It was a way to connect a device to a mobile network and store its number.
These days, SIM cards do so much more than that. These small, transferable cards are inserted into mobile devices and are still used to both identify and authenticate the device to a cellular network, just like the original SIM cards. However, they also store a wealth of data, like contacts, text messages, and a lot of other information that makes swapping devices a cinch. Because of SIM card technology, you are able to keep your number from device to device, or even carrier to carrier, while easily transferring hundreds of text messages and other data simply by inserting your current SIM into your new device.
Each SIM card is assigned a unique identification number that stores information about your network plan, such as type of plan, available data, voice minutes, and text messages. Carriers use this information to verify your account status and to apply charges and fees.
Whenever you send a text message or make a call, the device sends a signal to the network to request access. The SIM card is used to verify that your device is allowed to call or text within a network. If the SIM card is unauthorized, then the request is denied.
In addition to network data, personal information is stored on a SIM card. Things like your number, contacts, and text message history are stored on a SIM, which makes it easy to transfer information from one device to another.
Today, SIM cards are tiny, but that wasn&#;t always the case. Here are the different types of SIM cards and the devices you&#;re most likely to find them in.
The capacity of the original SIM card was just 32 KB, enough to store about five text messages and 20 contacts. The Micro SIM card, though smaller in size, has a memory capacity of 64 KB. A Nano SIM card is the smallest type of SIM card and usually has a memory capacity of 128 KB but can hold up to 250 contacts. It&#;s also possible to buy SIM cards with 256KB of memory storage. However, that is usually not necessary, since most newer devices offer much more storage and cloud capabilities.
One thing to note about SIM card memory capacity is that it differs from storage capacity. While newer SIM cards do have more memory capacity, nearly everything stored on a , such as photos, apps, and music, are stored with cloud technology and/or on an SD card.
Soon, it&#;s likely that devices won&#;t even require physical SIM cards. In fact, some of the latest smartphones do not even include SIM card trays. Here are the two most common types of embedded and cloud-based SIMs.
eSIM technology is convenient, since information can be transferred to a new device without requiring manual transfer of a SIM card. For example:
However, eSIMs are also more complex than physical SIM cards, which are fairly easy to swap. They require additional setup and configuration.
Soft SIMs have the same benefits as eSIMs but come with a few additional drawbacks. First of all, since a virtual SIM is cloud-based, it may not offer the same level of security as SIMs that are tethered to a device. Additionally, a soft SIM requires internet access to work, which can be frustrating in areas with poor connectivity.
From early SIM cards the size of a credit card, to SIMs that exist electronically, SIM technology has come a long way. And it&#;s very likely that soon, most of the connected devices we use will require some type of embedded or cloud-based SIM. But no matter which type you use&#; SIMs play a vital role in mobile technology&#;a role that is likely going to grow in importance as connected devices become common in more facets of day-to-day life.
