Galaxy S II – Model GT-I9100G The GT-9100G was released in late 2011, and is usually sold instead of the original GT-I9100 in certain markets (mostly Asia and some parts of Europe). An overview of the Galaxy S II GT-I9100G can be seen on
Samsung's official website. It features a Texas Instruments OMAP4430 SoC instead of the Exynos 4210 in the GT-I9100. It is visually identical to the GT-I9100, as well as having the same 1.2 GHz processor speed and dual-core ARM Cortex A9 processor technology. However, the SoC is of a different design and the Mali-400 GPU has been replaced by a PowerVR SGX 540 GPU. This difference in the SoC makes this variant incompatible with custom
ROMs intended for the I9100, but it has been steadily gaining its own aftermarket support (such as from
CyanogenMod) due to the relative ease of development and the openness of the TI OMAP platform.
Australia Telstra and Vodafone Australia – Models GT-I9100T The Galaxy S II (Model GT-I9100T) sold by
Telstra,
Vodafone Australia and some certain other carriers outside Australia is virtually identical to the I9100 and is functionally equivalent.
Telstra and Optus – Model GT-I9210T In Australia the Galaxy S II 4G (Model GT-I9210T) uses a Qualcomm processor and supports Telstra's and Optus'
4G networks. However, analog radio and digital media are not supported.
Canada Bell Mobility – Models GT-I9100M and SGH-I757M Bell's Galaxy S II is identical to the international version, except that its model number is GT-I9100M. All custom ROMs running on I9100 international versions can be flashed to the I9100M. Bell's Galaxy S II HD LTE (Model SGH-I757M) is identical to the cancelled AT&T Skyrocket HD hence making the device another variant of the South Korean model of the Galaxy S II HD LTE. One difference between the South Korean model and the Bell Mobility model is the lack of a physical home button, instead, four capacitive buttons are used, one of which directly replaces the physical home button. The specification of the device is identical to the South Korean model. However, different frequencies bands are enabled on this device.
Rogers – Models SGH-I727R and SGH-I927 The Rogers Galaxy S II LTE (Model SGH-I727R) is identical to the AT&T Skyrocket, and features a larger screen 4.52", a bigger battery 1,850 mAh, and a different 1.5 GHz Qualcomm processor. Rogers' Galaxy S Glide (Model SGH-I927) is the same phone with the same specs as the AT&T's Captivate Glide, except the carrier logo is on the back instead of behind the front glass panel.
Rogers launched the Galaxy S II LTE in fall 2011, soon after its
LTE launch in
Toronto. Note that the Galaxy S II LTE has a different model number: I9210 and came out later and only in select markets, including Canada and South Korea.
Telus Mobility – Model SGH-T989D Telus Mobility's 4G Galaxy S II X (Model SGH-T989D) is identical hardware-wise to the T-Mobile SGH-T989, including the Qualcomm 1.5 GHz dual core processor, larger 4.52 inch screen and 1,850 mAh battery. Although utilizing a different modem firmware, most custom ROMs running on T-Mobile versions can be flashed to the Telus T989D. The design differs from both the Rogers/International and Bell/AT&T models. There is a chrome band around the edge and the plastic on the back has a leathery feel. Instead of the hardware home button, it has the standard four capacitive buttons. The Qualcomm processor allows for 42 Mbit/s HSPA+ download speeds that the Samsung Exynos processor is not currently capable of. It was released on 28 October 2011. A subsidiary of Telus, Koodo Mobile, also offers the SGH-T989D.
China China – Model GT-I9108 (China Mobile), GT-I9100G, SCH-I929 The Galaxy S II (Model GT-I9108) was released in late 2011, and it is sold in China by China Mobile. It is identical to the GT-I9100G, featuring the same Texas Instruments OMAP4430 SoC with a 1.2 GHz dual-core ARM Cortex A9 processor and PowerVR SGX 540 graphics processor. However, the GT-I9108 has TD-SCDMA support in place of WCDMA support found in other variants. The GT-I9108 is a regional model and has few available custom ROMs. The Galaxy S II (Model SCH-I929) was released in late 2011, and it is sold in China by China Telecom. It is based on the design of Galaxy S II LTE (GT-I9210), but supports CDMA2000 1x EVDO for use with the carrier.
Europe – Model GT-I9100P The Galaxy S II (Model GT-I9100P) was released in late 2011. It has the same hardware as GT-I9100 plus the NFC chip and battery (the battery is specific because it includes the antenna). To keep NFC enabled it is necessary to update the firmware using a P version. Any I9100 firmware can be used, but doing so will disable the NFC hardware.
India Model: GT-i9100 GT-I9100 is a SIM-free model released on 2 May 2011. This model supports 2G/3G only, and a microSDHC card with a capacity of up to 32 GB.
