Re: Locked to T-Mobile? said by elray:said by banditws6:I actually applaud Google's effort to try to move us more toward the European approach to mobile phones ... However, if Google's hardware is only compatible with one domestic carrier, what is the point? Welcome to Google's concept of "choice". Be careful what you wish for. The phone is GSM. It works on both AT&T and T-Mobile, the only major U.S. GSM providers. Unfortunately, they use different spectrum for their 3G services. This isn't Google fault.
It's the exact opposite problem for iPhone 3G and 3GS users, who are restricted to Edge on T-Mobile's network.
Motorola is working on a radio that can use either frequency. The technology doesn;t exist yet. is Google responsible for the tech not being ready yet?
CDMA (Verizon & Sprint) is crap. It requires sticking to the current system.

| I had no idea that the technology to support both spectrums does not even exist yet.
Is there a "global standard" GSM spectrum that either AT&T or T-Mobile is not conforming to? Whichever one isn't conforming is the one that deserves my eye-roll.

Is there a "global standard" GSM spectrum that either AT&T or T-Mobile is not conforming to? Whichever one isn't conforming is the one that deserves my eye-roll. According to Wikipedia, »en.wikipedia.org/wiki/Universal_···s_System
The specific frequency bands originally defined by the UMTS standard are 1885–2025 MHz for the mobile-to-base (uplink) and 2110–2200 MHz for the base-to-mobile (downlink). In the US, 1710–1755 MHz and 2110–2155 MHz will be used instead, as the 1900 MHz band was already utilized.[6] While UMTS2100 is the most widely-deployed UMTS band, some countries' UMTS operators use the 850 MHz and/or 1900 MHz bands (independently, meaning uplink and downlink are within the same band), notably in the US by AT&T Mobility, New Zealand by Telecom New Zealand on the XT Mobile Network and in Australia by Telstra on the Next G network.
T-Mobile is operating within UMTS "spec" while AT&T is out of spec for 3G deployment frequencies.

It does, it just costs money. Qualcomm (and others) charge for UMTS IP (specifically WCDMA) per band, so most devices don't implement more bands than are necessary. There is also added cost in the hardware, but my understanding is that the licensing fees are more significant. |
