It is a quad band phone. it means it envelopes all the frequency currently existing in the cell world(for the gsm subscribers). thus if u have a gsm sim card u can enjoy this.

Yes, it is a quad band because it supports 850/1900/900/2100 on the GSM Network that's four but it depends were you want to use it, in the US it supports att. and now T-mobile with the 850/1900 but t-mobile is still building on that band it's not available everywhere it's about 90% their original band is 1700 and it also depends where in the world you are using the phone. Will not work with Verizon & Sprint.

Quad band so will work almost anywhere at 2G. However 3G is probably hit or miss depending on your selected carrier.

Dear customer, you have to verify with the carrier if it supports 850/1900 frequencies. We can recommend you a quad-band phone (instead dual-bad like the nokia 100) that will work on any GSM network. LG A275 Black Unlocked GSM Dual SIM QuadBand Cell Phone - International Version - No Warranty

The phones we sell are all unlocked from factory - quad band GSM frequencies: 800 / 900 / 1800 / 1900 MHz, making it compatible with all the major GSM networks in the world. The 850/1900 MHz bands are mainly used in the US, while the 900/1800 MHz ones are available in most other countries worldwide.

It says this in the description: "This unlocked cell phone can be used with a GSM network service provider and it provides quad-band connectivity (850/900/1800/1900 MHz)."However, I'm not sure how accurate that is. I can't find anything in a quick Google search.
