infobaba, no n0t all . .most of them require that you flash them with the firmware of the dual band . .e.g google "changing 6030b to 6030"

Nokia N73 supports all four GSM bands - 900, 1800, 850, and 1900 MHz so it a Quad Band phone

There are too many inconsistencies here

The facts are:

In GSM system, there is the uplink frequency and the downlink frequency

GSM systems use a pair of frequencies. Modern systems use a set of frequency from one band for uplink and another set from the corresponding band for downlink. e.g 900/1800

Dual Band

Dual band refers to the capability of GSM network infrastructure and handsets to operate across two frequency bands e.g. 850/1900 or 900/1800 MHz. In Nigeria it is 900/1800MHz

Tri Band

A Tri Band phone will operate on three different frequencies depending on the available network. e.g. 850/1800/1900 MHz. (This will not work in Nigeria)

900/1800/1900 will work in Nigeria

Quad Band

A quad-band mobile phone is operational on any of the four GSM frequencies - e.g. 850/900/1800/1900 MHz. This is indeed the ultimate global phone.

And will work on any GSM network in the world

The Single Band i.e 820/850, 1820/1850 (Pls note that these frequencies are in the same band) will never work here. The cost of conversion to dual band will be more than the cost of a new phone

.In addition to what infobaba said,

bands could also be defined as frequencies at which the service providers transmit their signals & your handset must be capable to operate at these frequencies in order to function with such

there are also single band phones 1900mhz(work mostly in the U.S) but most of them wont work here in Nigeria except a few changes if made to the hardware e.g replacing the 1900mhz gsm dcs module with a dual band module =900/1800mhz & flashing the phone with a compatible software . .

But what can you people say on those that use the phone that is using single band? Can we say that they will be experiencing poor service on their phone?

There is nothing like single band , at least not nowadays

You need two frequency bands!

People using band combinations such as 850/1800, 900/1900 will experience intermittent signal or no signal at all

There is also a quad band phone too 850/900/1800/1900

These bands are the frequency bands to transmit and receive

If you are using the phone in Nigeria, you do not need more than the dual band

All GSM providers in Nigeria are dual-band

But the dual band MUST be 900/1800 or include the 900/1800 combination whether triband or quad band

Any other combination such as 850/1800 or 850/900/1900 will not work in Nigeria

Eeeeeeeeen, what does GSM 900 and GSM 1800 networks or GSM 900/1800/1900 support mean?

The phone must support the same standard your provider supports.

When a phone is referred to as dualband, this usually means that it supports both GSM 900 and GSM 1800 networks; tri-band usually means GSM 900/1800/1900 support.
