T-Mobile rolls out 1900MHz frequency: unlocked international Galaxy S II GT-I9100 users can get 3G

Posted on Dec 21 2011 - 5:35pm by Brian

As a T-Mobile customer and Galaxy S II international version user, I’ve had to deal with using EDGE 2G data speeds–not fun.

T-Mobile mobile operates mainly on the 1700MHz AWS band which limits the ability for imported and unlocked devices (Galaxy S II, iPhone 4) to operate at 3G speeds. Luckily all of that is about to change as T-Mobile begins roll out operations on the 1900MHz frequency.

This expansion of frequencies is a result of T-Mobile’s parent company Deutsche Telekom brokering a deal with AT&T to allow their users to connect to AT&T existing 3G network. This means a couple things:

  1. Quadband GSM phones will have access to 3G data on T-Mobile–Galaxy S II, and iPhone among others included
  2. T-Mobile’s addressable population base increases by 21% from 230 million to 280 million
  3. Potential for iPhone to come to T-Mobile
  4. Faster adoption of international Samsung flagship phones–more on this below

With the Galaxy S II for T-Mobile, we were forced to wait for quite some time as the internals had to be swapped out for Qualcomm’s SoC. Aside from dropping the more favorable Exynos 4210 SoC, the switch causes delays in the release of new products for U.S. markets. This change was necessitated by T-Mobile’s operation frequencies. If T-Mobile continues to expand its network so that it shares frequencies with AT&T, rolling out new devices will require less time for OEMs and carriers and be less confusing for the end-users.

    The two murdered troopers, Power and Cahill, were men from good Irish
    families. Scores of reefs are now lying idle in Queensland from where tremendous yields were obtained near the surface, but which have been abandoned for want of capital.
    Neighbours were few and far between, high were only three other
    women living inside the neighbourhood – all
    lived in a choice of bark huts or tents using their young
    children.

    Just as your swelling falls just a little in reply towards the diuretic doesn’t imply you will get better.

    Do you have any idea how to tell if this has been rolled out in your area? Are their settings changes required on the Galaxy S2, to see the 3G network?
