What Does This Band Mean? by koseepaaro(m): 9:20pm On Jan 11, 2008 |
Hi all, Can anyone please tell me what they mean, if someone says "this my phone is two or three bands phone"? And also, what is the benefit of phone band to the user? |
Re: What Does This Band Mean? by MrInfo1(m): 10:02pm On Jan 11, 2008 |
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. |

Eeeeeeeeen, what does GSM 900 and GSM 1800 networks or GSM 900/1800/1900 support mean? |
Re: What Does This Band Mean? by oldie(m): 10:25pm On Jan 11, 2008 |
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 |

most sonyericsson are triband while moto quadband |
Re: What Does This Band Mean? by koseepaaro(m): 10:35pm On Jan 11, 2008 |
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? |
Re: What Does This Band Mean? by oldie(m): 10:49pm On Jan 11, 2008 |
koseepaaro: 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 |

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 |

koseepaaro: to be honest it doesn't matter! as long as your phone is new/relatively new leave all these mobile speak to mobile geeks |
Re: What Does This Band Mean? by MrInfo1(m): 8:34am On Jan 12, 2008 |
@ koseepaaro If the phone happens to be a single band, forget it, it can never work here (nigeria) @ dragnet Who need not to flash such phones, all you do is take it for unlocking |

What 'bout n73 Gsm 850\900\1800\1900. . . . . . How many gsm bands does this phone have ***probably 4** info tell us oh!. . . . |
Re: What Does This Band Mean? by oldie(m): 1:16pm On Jan 12, 2008 |
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 |
Re: What Does This Band Mean? by MrInfo1(m): 2:17pm On Jan 12, 2008 |
tope_teadr: Nokia N73 supports all four GSM bands - 900, 1800, 850, and 1900 MHz so it a Quad Band phone oldie: |
Re: What Does This Band Mean? by topeteadr(m): 5:27pm On Jan 12, 2008 |
infobaba:Nawa oh This is 4 nokia 6070 GSM 900 / GSM 1800 / GSM 1900 well i guess most nokia phones hae at least 2 gsm band's. . . . . ***not talking 'bout 3310 oh!. . .*** 3310 even get two band's |
Re: What Does This Band Mean? by dragnet: 9:01pm On Jan 12, 2008 |
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" |
