Hi Linda! So, here’s the thing with the unlocked iPhone: it will only work with a carrier that operates a GSM (or “Global System for Mobile Communications”) network, and not on carriers with CDMA (“code division multiple access”) networks.

Here in the United States, for example, the unlocked iPhone 4S will work on AT&T or T-Mobile, which are both GSM carriers, but not Sprint or Verizon Wireless, which are CDMA carriers.

How can you tell whether your carrier is GSM or CDMA? Simple. A GSM carrier uses something called a SIM (short for “Subscriber Identification Module”) card to identify a specific phone on its network. These little plastic chips can be swapped in and out of a GSM-based phone, allowing it to connect to the particular network to which a given SIM card is tied.

This is an updated unlocking tutorial with new repo sources to show you how to unlock any CDMA or GSM Sprint Verizon or At&t iPhone 4S or 5.1.1 or lower for T-Mobile or any GSM carrier world wide. But the iPhone 4S changes all that: It can access either the CDMA or GSM network, depending on which carrier you sign up for. For consumers on CDMA networks, this new phone design is a big deal.

So, if you’re curious whether your carrier runs a GSM network, just check your cell phone for a SIM card slot; it might be on the side of the phone (as in the case of the iPhone), or inside the handset itself, usually behind the removable back panel and near the battery.

Can’t find a SIM card? Then you might have a CDMA-based phone, which doesn’t use a SIM card—and that means your carrier runs a CDMA network. (If in doubt, you could always just call your carrier and ask, of course.)

Side note: The new iPhone is, in fact, a so-called “world phone” that will connect to both GSM and CDMA networks. That said, Apple has specified that the unlocked iPhone 4S will only work on GSM networks.

If you do decide to get an unlocked iPhone 4S for your son (lucky him!), you’ll need a special type a SIM card from your local carrier: a “micro-SIM,” which is basically a smaller version of a SIM card. Be sure to make the distinction when placing your order, as a regular SIM card won’t fit in the iPhone 4S.

Want to know whether your smartphone uses GSM or CDMA or want to know what the differences are between the two? Read through this article to find out.

GSM and Global (CDMA) are essentially different types of mobile technologies used by mobile devices across the world. Do note that in this article Global is referred to as CDMA as that is the same thing.

Global Vs GSM - The Major Differences

In terms of overall performance, you won’t find any noticeable differences between GSM vs CDMA. However, there are some limitations depending on which country you’re in.

Typically, CDMA devices are found commonly in the United States and Russia. Interestingly, CDMA was originally developed during World War II as a technology that could be used to communicate without axis forces being able to intercept or jam signals.

These days, CDMA has evolved into being widely used as a smartphone and mobile technology for everyday consumers in the USA and Russia.

CDMA devices do not use SIM cards and are instead tied directly to a specific network.

GSM, on the other hand, uses a SIM card to allow a user to send messages to and from other mobile owners. GSM is the network we see most commonly throughout the world.

These days, the United States has started to use GSM technology more commonly to give users more freedom over the network they use.

In the past, Verizon and Sprint would use CDMA in the USA, whilst AT&T and T-Mobile used GSM.

With the fast spread support of LTE, more smartphones in the USA are moving over to GSM from all four networks.

GSM is considered to be the better technology - you can switch out your SIM card to use other networks across the world, and you’re given more freedom over which network you use.

How To If Your iPhone Uses GSM VS CDMA

If you’d like to learn about what network type your iPhone uses, the easiest way to find out is to find your model number and compare it with data available online.

To begin with, you can find your iPhone model number by looking at the back of your device. The model number will be printed onto the bottom of the back plate.

If the text on the back of your iPhone is worn out, you can also visit the settings to find your iPhone model.

Head to the Settings app, tap General, and then tap About
Scroll down and search for the Model listing
If you do not see the model number starting with 'A', tap on it and it will toggle it

Once you know your iPhone model, you can compare it with the model numbers provided below to find out which network your iPhone uses.
