Method 1: Check iPhone Model Number

Apple provides a different set of model numbers for different phones. You can use these model numbers to determine what kind of iPhone you have. On the iPhone, navigate to ‘Settings’ and click on ‘General.’ Choose the ‘About’ option, and you will see the ‘Model’ number. You can Google search the model number to determine the type of iPhone.

Here are the model numbers for iPhone models:

  • iPhone 5: A1428 , A1429, and A1442
  • iPhone 5C: A1532, A1456, A1507, A1529, A1516, and A1526
  • iPhone 5S: A1433, A1453, A1457, A1530, A1533, and A1518
  • iPhone 6 & 6 Plus: A1549, A1586, A1589, A1522, A1524, and A1593
  • iPhone 6S & 6S Plus: A1633, A1688, A1700, A1634, A1687, and A1699
  • iPhone SE: A1662, A1723, and A1724
  • iPhone 7 & 7 Plus: A1660, A1778, A1779, A1780, A1661, A1785, and A1786

  • iPhone X: A1865, A1901, and A1902

Method 2: Check Carrier Settings

In many cases, the iPhone carrier plays a vital role in determining the suitability of the iPhone for global usage. Some carriers do not allow customers to use their network on a different continent, which means that the domestic version iPhone would not work on another continent. You can navigate to the ‘Settings’ option, click on the ‘Carrier’ option, and see if your carrier supports global usage. If your carrier supports global usage, then your iPhone is an international version.

Method 3: Check SIM Card Slot

The most noticeable difference between domestic and international version iPhones is the SIM card slot. International version iPhones are designed with a unique SIM card slot that can take various SIM card sizes, including GSM and CDMA SIMs. In contrast, domestic versions may not have a SIM card slot or are restricted to particular networks. If your iPhone has a SIM card slot, you can use a local SIM card in different countries easily.

Why Can’t I Use My Domestic Version iPhone Internationally?

There might be several reasons why you can’t use your domestic version iPhone internationally, such as incompatibility with different frequencies, language, and carrier networks. Every country has different network frequencies, which means that some domestic versions of the iPhone may not support networks in other countries. Additionally, domestic versions of the iPhone may not be compatible with different languages, which can make the phone unusable in other countries.

Moreover, domestic iPhone versions are mostly carrier locked, which means that they are confined to a specific network within a specific region. The carrier may not allow you to use the phone outside its designated region, or it may charge additional fees for using your phone outside the country.


If you have a domestic version of the iPhone, and you want to use it overseas, you may need to contact your carrier to unlock the device. Contacting an Apple Support Representative for advice is another solution. In many cases, Apple can provide you with recommendations on handling the phone while you are overseas. Apple’s representatives may guide you in updating settings, changing frequencies, and language, among other things.

Lastly, using a global SIM card can be helpful if you frequently travel abroad. Global SIM cards are designed to work anywhere in the world, and they usually offer better rates than most domestic carriers. Global SIM cards can be bought at airports or in different shops in different countries.
