Find Your Models – Samsung Galaxy S3 Series

Samsung Galaxy S3 helped Samsung rise to a dominating position in the smartphone market, taking the largest piece of market share. Before its release, the Galaxy S3 already had 9 million orders. Finally, after it was available in nearly 150 countries, the handset had gained a reputation and sold 50 million units as of 14 March, 2013.

For most Samsung Galaxy S3 models, their international versions are different from the US variants. For example, the International version Galaxy S3 I9300 has no 4G Network service but features an FM radio, while the AT&T SGH-I747 includes the 4G Network but does not have an FM radio. The Galaxy S3 is available in many different models: GT-I9300, I9305, SGH-T999, SGH-I747, SCH-R530, SCH-I535, and SPH-L710. You may not even know which one you have. For example:

GT-I9305 for International LTE SGH-T999 for T-Mobile SGH-I747 for AT&T SCH-R530 for Cricket Wireless, U.S. Cellular, MetroPCS SCH-I535 for Verizon SPH-L710 for Sprint, Boost Mobile, Virgin Mobile

Some components of different GS3 models appear very similar, but will not fit or function when put in the wrong model. It is necessary to know your exact S3 model when you need to flash ROMs, or when you fix your broken S3 (Click to learn How to Teardown Galaxy S3). Therefore, you need to identify which model you have. Here are five ways to find out.

1)    Check Your Galaxy S3 Model Number in the system
Navigate to Setting> About device> Model Number, then you will find the model number on the screen.

2)    Check the Battery Door
Some carriers’ logos are printed on the battery door, which will make it easier for users to tell their versions. Such as this Verizon SCH-I535, AT&T SGH-I747 and Sprint SPH-L710 model.

If it is international version, only the Samsung logo will be printed, such as this GT-I9300 battery door.

3)    Check Behind the Battery
Another solution is looking behind the battery. Many manufacturers put the phone model along with other information in this area.

4)    Check Under the Housing
The model’s number is marked behind the housing. Below you can see the slight variations in design between the two versions.
5)   Check Under the Rear Housing
The rear housings on different models also have different contacts at the bottom. You can compare the contacts on your model with those in the pictures below to identify your model.
