Sim Card vs SD Card? Sim Card is a card that is designed to store or hold information and let us connect to the network while SD Card is a memory card that is installed in various digital devices.
Sim card
Generally, the term ‘Sim’ stands for ‘Subscriber Identity Module’ and usually it is a very small card made up of plastic that fits into your phone. Every smartphone has a slot in it, especially for the Sim Card. All the smartphones that are ever made always have Sim slots.
In layman’s terms, a SIM card is a small, portable memory device that stores information about you as a mobile user. In it, there is a seventeen-digit code that identifies its native country code, a system administrator such as AT&T or Verizon, and a unique user ID.
History of Sim card
The SIM cards were inserted much later in 1991. The first SIM card was the size of a credit card. Since then, there have been several revisions and repetitions, making them smaller and tiny in size due to the demands of consumers as well as the smartphones.
This evolution is closely related to the history of the GSM which is abbreviated as Global System of Mobile Communications, a mobile network. Designed to define 2nd generation mobile network (2G) protocols, GSM today stands as the default global mobile communication standard.
SIM cards are an integral part of GSM networks, which store user information required for authentication. Ultimately, this allows your phone to connect to the GSM network and GSM networks to track your phone usage especially your minutes, texts, data usage, etc., giving carrier’s information to send you accurate phone credit.
GSM is a standard network in Europe, Asia, Africa, and many other places. There is an interesting note about it that in addition to GSM, the United States has an additional network called CDMA which is abbreviated as Code Division Multiple Access, used by carriers such as Verizon and Sprint. Phones in the GSM or CDMA network can use any network, reducing the cost of carriers and users.
When it comes to connecting your phone with any network, SIM cards are actually the brain of your device. Without it, you cannot even imagine having a phone. It is a basic necessity of mobile phones as water is essential for human beings to survive.
Types of Sim Card
There are three basic SIM card sizes:
-
Standard
-
Mini, and
-
Nano
Of the three, the Standard is the original and larger SIM. Today, these are widely used in older phones. The Micro SIM card is actually a standard SIM card with the extra plastic around the shaved circuit board.
A cut-out version of Micro, the Nano is the smallest and is used on modern iPhones. Although the minuscule is compared to previous versions, the Nano still holds the same amount of data as the previous SIM cards.
Mini Sim
When you unplug the SIM card, you may notice that they are very thin. But before the launch of the iPhone 4 in 2010, we actually had one SIM card size. Launched in ‘96, it was a standard feature used throughout the phone and delighted the GSM people. In fact, it was your whole phone on the card. It made things easier.
If you want a new phone, all you have to do is remove the SIM, plug it into any phone and suddenly your phone number will be transferred to the new device. For more than a decade, this has been the norm, making calls like blowing of the wind.
Micro Sim
Talking about iPhone, wanting to save valuable room for its new generation of smartphones, Apple has moved from the use of a standard Mini-SIM to a Micro-SIM when the iPhone 4 hits the shelves. Surprisingly, Micro-SIM was not just another bright new SIM made for the latest iPhone. Believe it or not, it was first launched in 2003.
At the time, its purpose was clear and that was if the device was too small to fit a mini-SIM, you would have to use a micro-SIM. In addition, the micro-SIM is designed to be compatible with backlinks, which means it can work with installed versions of an older version of the SIM.
Moreover, apart from its small size, the performance of the micro was not affected at all, as the contact area of the chip remained intact. It turned out to have been low valued, the card only needed its own extra plastic to cut into it.
When Apple released the micro-SIM iPhone 4, it became the standard for most smartphones. Samsung, Nokia, and HTC are just a few of the manufacturers that have adopted the new Micro-SIM. Meanwhile, several upgrades to the iPhone 4 have chosen to use an adapter to get their SIM cards reduced to Micro’s, too.
Summary
Innovations are made when there is a demand from the company or the customers. In the same way, the variations in the sim cards and their sizes were made to meet the demands of the market.
Nano Sim
If you think Apple is made using small SIM cards, think again. Perhaps Apple apologized for using the SIM card since 2003 on the new shiny iPhone. Maybe they wanted to stay ahead of the curve and throw rivals out of their way.
In any case, the launch of the iPhone 5 has inspired the public to see a new SIM in the city which is the Nano-SIM. This choice of small size makes life very difficult for users. Anyone upgrading to iPhone 5 or from Android now had to get a new SIM card or adapter.
Fortunately, many Smartphones released since 2014 including both iOS and Android who now support Nano SIM card technology. However, it is sad to see a slow-moving card, as it has always been easier to switch phones with a Standard SIM compared to the Nano.
SD card
SD card is a small data storage tool. It is usually installed on your camera or mobile phone so you can store photos, videos, and other files on it.
SD card can be called “SD memory card” or “Secure Digital (SDSD) Card.” Traditionally, these cards were used on digital cameras to take photos and are now being used as removable media devices with many types of electronic devices such as tablet computers and laptops.
There are various sizes of SD cards: some hold only less than one gigabyte while others contain up to 128GB. Features of popular favorites available today include:
Medium Cards which is currently the smallest size available, about one-third the size of a traditional SD card.
Micro SD Cards which are slightly larger than Mini Cards, commonly used for Smartphones and tablets.
Standard; the original SD card type is labeled “full size” or “standard.”
Facts about SD Card
To find a memory card, consider card size, compatibility, size, speed, and the type of files you plan to save. Reasons to choose this are as follows:
1. Both body size and compliance issues
Fully compact SD card cards are commonly used with large devices such as computers, laptops, and digital cameras. Mini SD cards are small and often work with tablets, some phones, and some digital cameras. Micro SD cards are smaller and smaller and are more commonly used on mobile phones.
Memory card adapters work with different cards to make them compatible with standard SD card spaces.
2. The capacity limit, what types of files you save
Selecting the appropriate final volume depends on the type, size, and number of files you want the card to hold.
3. Transmission speed is important
The speed at which the memory card can read and write data is essential for capturing video for smooth playback of your recordings. SD cards are available in Speed Class or UHS Speed Class. The speed category is indicated by a number.
Remember, not all SD memory cards work on all devices. Check the user manual to find out what type of card is compatible with your device. SD cards can work with SDHC cards, but SDHC and SDXC cards will not work with SD spaces. Once you have determined the type and size of files you plan to save, you will be able to decide which SD card memory will work best for you.
