Unboxing that new iPhone, Samsung Galaxy, or Android device is a great feeling. But your mobile phone number is useless if it doesn't have a SIM card.
SIM stands for "Subscriber Identity Module." It's a tiny memory chip that cell phone carriers use to attribute bills and services. Essentially, it's how T-Mobile, Verizon, Sprint, or AT&T can identify their subscribers.
You need a SIM card to be able to make calls, send text messages, and connect to a mobile network. While most phones come with an active SIM, you might need to activate it on a new device manually.
It can get tricky if you're doing SIM card activation for the first time. Here's a look at how the activation process works.
How Do You Activate a SIM Card?
At a glance, activating your SIM card is simple. Here's a brief overview:
- Put the SIM into your phone, and turn the phone on.
- Use the activation key to activate your new SIM card.
- Activate the SIM card online as well (use the activation key).
- Wait for the SIM card to activate.
Note that most mobile carriers will do all of this for you if you get a new phone in one of their physical locations, so you might be able to avoid some of these steps entirely. Of course, if you bought a SIM card yourself, you can do it from home.
Step One: The Activation Key
The activation key is a unique code that comes with the packaging of your SIM card so that you can activate the SIM card for use. Before you can put the physical SIM card into your phone, you'll need to activate this code online.
You'll need wi-fi or an internet connection to be able to do this step, and we recommend using a computer or somebody else's phone.
While you can use your new phone without a SIM card to connect to the internet, the initial setup process is much simpler when you can have an active SIM before beginning.
Read the instructions in the packaging carefully, enter the activation key, and then wait a bit. It should be activated soon.
Step Two: Put the SIM in Your Phone
Next, you can place your activated SIM card into your phone. The process for doing this varies depending on your device. In most cases, the SIM is located in the same place where you would access your phone's battery.
However, some phones (like the iPhone) don't make it as easy. With an iPhone, you'll need to get a paper clip and poke a pinhole on the side of the phone. This will open up a compartment for you to insert the SIM card.
Step Three: Activate the SIM on Your Phone and Online
Next, you'll log into the SIM provider's online service, which you can do through a web browser. Make sure you know your login details and have your SIM card number ready. Typically, once you reach the provider's website, it'll guide you through the following steps.
How Long Does Your SIM Card Take To Activate?
The time it takes to activate a new SIM card varies, but most activations won't take much longer than 15-20 minutes. If, after four hours, your SIM is still not updated, try restarting your device.
If it isn't working, re-insert the SIM and contact your SIM provider for troubleshooting steps.
What Does a SIM Card Do?
Your SIM card will connect you to your mobile plan or a new carrier if you switch mobile providers. It's essentially your gateway into using your mobile provider to make calls, send and receive texts, and use your data plan.
Your phone can still function without a SIM card. You can still access the internet through wi-fi to download apps, surf the web, and make video calls. But if you want to text or call, you'll need to ensure you have a SIM card through your carrier.
How Expensive Are SIM Cards?
SIM cards are often bundled alongside new phones, or they'll give them to you if you sign up for a new phone plan. So while they're not necessarily "free," you often do not need to pay a separate fee.
But if you choose to buy a SIM card separately, they're relatively inexpensive. Typically, you'll pay anywhere from $45-90 for a new SIM card. Remember that you'll still need to pay for a monthly service plan to use the card itself.
Are There Different Types of SIM Cards?
There are different types of SIM cards, and each one is used for different circumstances.
- Standard SIM
- Micro SIM
- Nano SIM
Despite the name, standard SIM cards are no longer the most common SIM card you can find. These were used upon the launch of SIM cards way back in 1996. It was used in old flip phones up until the iPhone 3G. But now, this type of SIM has been relatively phased out.
The memory chip in a standard SIM is the same size as the other two types — the only difference is the card's physical size. So since mobile devices have gotten smaller and sleeker since 1996, the size of the SIM had to update too.
Micro SIMs are a bit smaller than standard SIM and aren't widely used anymore. They were introduced in 2003, and while they're small enough to fit into phones like the Samsung Galaxy S5, they are still a bit bulky for many newer devices.
The phone you have in your pocket is probably operating on a nano SIM. These are super tiny, and there's almost no border around the memory chip.
Again, these memory and function are no different from the other two — they are just physically smaller and more lightweight. Tech manufacturers prefer this as they continue to make thinner, smaller phones and tablets.
SIM cards are a way for you to call and text through your mobile provider, and it's also a unique "key" that allows mobile carriers to identify you.
Most new phones either come with a SIM card, or your mobile provider will set them up for you in-store. But if you buy a phone online or a SIM card separately, you'll likely need to activate it yourself.
You can activate a SIM card as long as you have an internet connection and activation key, which will come with your SIM's packaging.
For some devices, you'll have to insert the SIM card into your device in the same place as the battery. For others (iPhones), you just poke a paperclip into the tiny hole on the side of your device.
If you get yourself a new business phone, you may need to follow some of these steps. And once your phone is set up, you can start managing your business directly from your device.
