    SGH-T989D vs SGH-T989

      I live in Canada half time and the US half time.  In Canada I use Telus and while I'm in the USA I use T-Mobile.  I'd like to get one phone that works on both networks.  Telus sells the Samsung SII SGH-T989D but T-Mobile sells the SGH-T989 (no D).


      Assuming I can get the Telus phone unlocked, will it work on T-Mobile?  Full internet speed and all?


      Thanks for your help!

          Galaxy S2 (Telus) used this frequency  GSM: 850MHz / 900MHz / 1800MHz / 1900MHz                      

          UMTS: Band I (2100MHz) / Band II (1900MHz) / Band IV (AWS) / Band V (850MHz) 


          Galaxy S2 (T-mobile) frequency:1900 MHz UMTS/HSPA/HSPA  Class 3g/4g , this phone used qualcomm chips, while AT&T and International version used Exynos chip


          It might work? Try to contact T- Mobile Customer Service

            Hehe. Thanks for your reply. Spoken like somebody who's never called an 800 number in his life! Of course that was my first step and yes I called both Telus and T-Mobile. The calls went like this:


            "Hello. My name is John. I am please to be of helping to you today. How 'bout our local team? Did they not cause much humiliation to the enemy at the sporting venue recently? How may I be of disservice?"


            And it was all down hill from there.


            But thanks anyway.

              They're different bands.  So, most likely not.


              Well, the voice will work.  Just not full speeds.

                Yes, it will work. They are essentially the exact same phone. On XDA, the same ROM works for both phones. In fact, my T989 on T-Mobile is using the radio firmware from the Telus T989D. I think the difference is that Telus uses 3G/HSPA+ bands only and does not have Edge/2G, which is not a big deal in most areas.
