SIM Cards Simplified
Reading time: 7 minutes
If you’ve ever wondered what a SIM card is, what SIM cards do, where it goes, why it’s called a SIM card, and what happens if you switch it out, get ready because PureTalk is giving you the scoop right here in "SIM cards simplified".
What is a SIM card?
Your SIM card stores the information that enables your service provider to recognize it. Otherwise you couldn’t text anyone or make phone calls. Your phone number is stored on your SIM card along with what are called “authorization keys.” These give your phone authorization to access data, send text messages, the ability to make and receive phone calls, and other services provided by your cell phone plan.
Without a SIM card, your mobile device could not access and receive calls or utilize your wireless provider’s network.
What does a Subscriber Identity Module (SIM) do?
According to the people at Wikipedia, “A SIM card is an integrated circuit (IC) intended to securely store an international mobile subscriber identity (IMSI) number and its related key, which are used to identify and authenticate subscribers on mobile telephone devices (such as mobile phones and laptops)."
The data contained on a SIM card is what allows you to access your wireless provider’s network with your mobile devices (mobile phone) and utilize the features of your phone plan. It’s a small smart card that is shipped to you once your order is complete.
Where is the SIM tray located?
On iPhone, the SIM tray is located on either the right or left side of your phone. On an Android phone, it is located on the top, bottom, or side. It depends upon the model of your phone.
What happens when you change your SIM card?
The short answer:
Changing your SIM card enables you to use any mobile communication device on your wireless provider’s network, so if you need to switch from one smart phone to another for some reason, you can do so without a problem. Also, if your SIM card goes bad or is damaged somehow, you can put a new SIM card in your mobile device, though you’ll lose some information.
The longer answer:
When you put in a new SIM card, you lose access to the information stored on the original SIM card. The information – phone numbers, addresses, text messages – is still on that original SIM card and all you need to do is pop it back into your cell phones to access it. To make absolutely sure you always have that information, you can also import it into your cell phones. This means that with or without your SIM card, you have access to your contacts.
Benefits of Dual SIM cards
According to the experts at Victra.com, “Individuals who want to keep their personal and professional lives separate can benefit greatly from having a dual SIM phone. One SIM card can be used for personal uses and another for business reasons. For users who need to stay connected to multiple networks, having a dual SIM phone can significantly improve connectivity. Dual-SIM phones can accommodate two separate phone numbers from different carriers or regions on a single device. This feature can significantly improve privacy. Activating second number on a dual sim smartphone can be beneficial when traveling internationally. You can keep your primary number active while also activating a local number for calls and texts.”
How to import contacts from your SIM card to your iPhone
Put your original SIM card, as it’s the one with all your contacts, into your iPhone.
Tap Settings > Contacts>Import SIM contacts.
Wait for the import procedure to finish.
Open Contacts and check that your contacts were all imported.
How to import contacts from your SIM card to your Android cell phone
Open Contacts settings.
Tap the “More” option.
Select “Manage Contacts.”
Tap “Import/Export Contacts” and select Import.
Tap the contacts you want to transfer, then tap “Done.”
Save the contacts to the phone.
Copying your SIM card
For further protection and assurance that your contacts are available to you, you can also make a copy of your original SIM card. This will leave you with two SIM cards, both with the exact same data (except for the unique IMSI identification number on each).
You can now keep one SIM card in your device and the second SIM card as a backup should you need it. Just keep the second SIM card someplace safe. (Do the same with any additional SIM cards, too).
To copy your SIM card, you’ll need a SIM card reader (something you can buy at any large electronics retailer) and your original SIM card’s IMSI number.
Place your original SIM card into the SIM card reader, then connect the reader to your computer. Input the device’s IMSI number when prompted and you will receive an authentication key. Once your SIM card reader has copied the information from your original SIM card it to your computer, you can insert a new SIM card into the reader and the information will be transferred from your computer to the new SIM card.
