What is the diffference between Global GSM and US GSM?

The difference is the frequencies it uses. Global GSM will be fine for ATT, you will probably want US version for t-mobile though.

The US version supports T-Mobile 1700/2100 Mhz AWS frequencies, which have been used in the past for T-Mobile all across the US. Currently, T-Mobile is shifting much of the 3G HSPA traffic to 1900 Mhz, which was previously used for 2G. This shift frees up the 1700/2100 bands for 4G LTE use. Google "t mobile frequency refarming" to find details. To get the best T-Mobile coverage across the USA, buy the US version of the phone. If you will use the phone in mostly a major metropolitan area with refarmed frequencies (like the SF Bay area), the Global GSM version works just fine and does get high speed 3G (HSPDA+) on T-Mobile, AND has better compatibility in places like Europe. If you never expect to use the phone outside the USA, get the US GSM version. I bought a Global GSM Moto G for a friend recently, and it works great in the SF Bay Area, and it worked great on a trip to Europe she took.The US GSM version does not support the 900 Mhz HSDPA band, which is widely used outside the USA. Amazon's comment about the Global GSM phone supporting T-Mobile on 2G only is not really accurate, although would apply if you did not live in an area with refarmed frequencies.

Verizon uses CDMA System, While it has some minor advantages and covers more areas only in this country, It is fairly limited to US Market and you cannot use it overseas. Beside you cannot use a Verizon phone with another carrier. GSM, On the other hand is almost universal and you can use your phone outside USA. Other advantage of GSM is that you can use your phone with another GSM Carrier(you need to unlock the phone first which is not difficult) and installing a small card, Called SIM Card in your current phone. So CDMA(Verizon) is not necessarily the leader. It is possible that the newer LTE System and 4G technology could replace both system and we end up to with one universal system.

It's global, the one i got was hong kong but anything outside of US is global. You don't get 4G in the US.

The only difference between the USA version and the international version is the terms of warranty. The model bought in the USA will have a warranty that is valid only in the USA. Since this is a Penta-band phone, it will work allover the world no matter which country you purchased it in. Hope that helps. Don't forget to register your device with Nokia once you receive it.

I have only ever used my phone in the US but because of the carrier I use I can only access EDGE (E) and GSM (G) cellular networks. Apart from the low bandwidth it works fine.

Look for a carrier which is said to be GSM "Global System for Mobile", some of the US carriers that use GSM are t-mobile, At&t;, Net10 wireless, H2O wireless, and others. Most of these offer 3g connection service. This is one of the two types of connection protocols in the United States, the other being cdma. GSM phones allow insertion of a sim card, cdma phones do not. Sprint and Verizon are the major cdma carriers in the united states.cheers

Go to this article on line, it will tell you. You need to know who the original carrier was: AT&T... T Mobile etc. You want a GSM based phone to be sure of international use, though there are hybrids from some other companies. http://www.cellularabroad.com/intro-overseas.php

This isn't an easy answer. Different carriers require different bands across the world. Purchasing the "Global"is the safest option. This guarantees your phone will work with every carrier overseas. However, the service may not be as good or even be only 2G (edge) speed. If you buy the AT&T; version, there is no guarantee of it working outside of the United States. Even if it does,AT&T; has optimized it for their network and may not work as well abroad.

No it is not unlocked for worldwide gsm usage. But you can get it unlocked on your own for free with AT&T or you can use DC-Unlocker and do it yourself.

Models G900H, G900F are International Version (NOT Support 4G LTE in USA). G900A is US Version from AT&T and unlocked for use with any GSM sim card including International. Thank you for question!

Also, Net10 (and Tracfone, and Straight Talk) are US services. Even if you choose a GSM phone from these companies, they are locked devices, and you can't use any other SIM other than the one that came with the phone. You'll want to buy an unlocked GSM phone, and buy a SIM and service for the country you're going to use it in.
