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:
- Quadband GSM phones will have access to 3G data on T-Mobile–Galaxy S II, and iPhone among others included
- T-Mobile’s addressable population base increases by 21% from 230 million to 280 million
- Potential for iPhone to come to T-Mobile
- 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.
