1800mhz gsm and 850mhz 3g umts? Does this item work on 1800Mhz GSM and 850Mhz 3G UMTS?This item has a really bad specification. Not very informative. I think that for 1800Mhz GSM it's OK, however, on the website of Blackberry (http://worldwide.blackberry.com/blackberrypearl/3G/pearl_specifications.jsp) it says Tri-band UMTS networks: (800/850)/1900/2100 MHz and 900/1700/2100 MHz. What does this mean? That the are some Pearl that supports (800/850)/1900/2100 MHz and others 900/1700/2100 MHz? What does mean (800/850)? That it is one or the other, or both?Hope someone can answer this (thanks in advance).Best regards,B. 1800mhz gsm and 850mhz 3g umts?

According to the products description, I believe it is GSM quadband meaning (800/850/1900/2100 MHZ) and Triband 3G (900/1700/2100 Mhz).

- Celular (por supuesto)- Bateria- Cargador- Cable de Datos- Un forro (inutil, queda EXAGERADAMENTE ajustado)- Los auriculares o manos libres no recuerdo ni los vi pues nunca los uso, ni teniendo la necesidad, los extremos no son nada comodos...- Memoria de 2GbEn general los accesorios que trae normalmente comprado original... no se si me falte algo en la lista, pero trae todo. Espero te haya servido de algo.

It only partially supports T-Mobile 3G/4G HSPA bands. It does not support the 1700mhz band which is what the majority of T-Mobile's 3G/4G HSPA service uses. They have refarmed some areas to use the 1900mhz band but not all of them. It is also hard to find out what areas have been refarmed but there is a map out there somewhere that shows it. However, it does appear to have full 2G and 4G LTE coverage

Dear Rixio, Sorry but this phone Ido not work at 1900mhz 3g band, because in my country i have a Operator phene company works ay 900 Mhz. Regards

Of course it does, on 850, 900, 1900 and 2100 frequencies, but, take in mind it's 3G only works on the 850 and 1900 frequencies, so check out if it's gonna work in your country, with your company, before buying it.

Definitely will work on AT&T; but there are some qualifications. On quad band 2g GSM it will work on 800 and 1900 mhz. On dual band 3G, it will work on 800 mhz. However, it will not be able to use 3G 1900 (only has 800 mhz USA and 2100 mhz 3G) nor will it be able to use LTE unless indirectly through a separate mifi device (I do this). There are some APN data settings included with the phone that should work with an AT&T; direct sim chip but may not work with the data settings with AT&T; resellers like RedPocket, H2O, etc....those would have to be manually programmed in...I don't bother with that and just wirelessly tether via wifi to a hotspot or my AT&T; mifi device.

Please check if your carrier is compatible with any of the following GSM bands in your area: 850 / 1900 / 2100 Mhz. If so, it will run on 3G.

Besides the obvious differences on the 3G frequencies (2100 on EU, 850 on USA), I don't know.

The phone should work for calling pretty much everywhere. But using it for 3G data is a different matter. As another answer pointed out, this model usually comes with just two 3G bands, and the two bands can be different pairs depending of where the phone was sold. And the problem is, the sellers here on Amazon often don't specify which of the two 3G bands that particular phone is equipped for -- 850/2100, 900/2100 or 850/1900. Without knowing those details, it's hard to know whether the phone's 3G will work in wherever you may be.

yes. This item can support 2G:GSM850/GSM900/DCS1800/PCS1900. As fore 3G, only for 3G: WCDMA 850/2100MHz. I hope this can help you!

I honestly couldn't tell you either way, but according to what I saw, it said I had 3G signal, but obviously blackberry works on a different network which is why it didn't work with me

This phone is Dual band , it is CDMA and It is GSM, you rather buy GSM blackberry than buying Dual one. Please notice all blackberry work worldwide if they are unlocked.

To put it simply: For 3G this phone supports UMTS 900/1900/2100 MHz frequencies. T-Mobile 3G (in the US) uses AWS 1700/2100 MHz (up link/down link) so the phone can't get to the 1700MHz frequency band to make the connection.
