According to T-Mobile's spec page for their 9900, the T-Mobile 9900 includes At&T's frequencies: 850 and 1900 MHZ. See T-Mobile Support Community: Tech specs - BlackBerry Bold 9900

Can anyone with an unlocked T-Mobile 9900 please drop a AT&T SIM card in their phone and see if they get a AT&T 3G signal on their T-Mobile 9900?

Thanks.

The 850 listed on that page is for 2G/GSM bands, not 3G.

Are you sure? I was asking some other people here on the forums and some say yes and some say no... I asked a few friends at T and they said they're compatable for 3G... I mean the numbers add up. But who's brave enough to test it??

Yeah in the past tmo has never put in the 850/1900 3g/4g needed to use on att but with the proposed merger it is possible it was incuded. It would be great if someone could test out so we would know for sure?

[nytrackstar]

No 3G on Tmo 9900 when using with ATT, only EDGE.

Have you tried it. How are u so sure?? WHere is a link to the full 3g/4g specs?

[BBtoiPhone]

For all you that are say it might be because of the merger, this morning in the news it stated that the government was trying to stop them from merging

[greggebhardt]

Compare the bands that T-Mo uses and the bands that AT&T use.

Thee have been several threads where somone bought a T-Mo units and are complaining they only get EDGE.

Even though T-Mobile spec sheet includes AT&T's frequencies (because of the hopeful merger), these frequencies could be locked out at this time.

If you have actually put a AT&T SIM card in an unlocked T-Mobile 9900 and only got an EDGE signal, that is all I need to know. Is that indeed the case?

If not, I really would like to have an answer from someone who has actually tried. Because, if you can get an AT&T 3G signal with a T-Mobile 9900, I will buy one today.

Thanks.

I am well aware that at&t uses 850/1900 for 3g and Tmo uses 1700/2100, thing is the bands are not listed on the Tmo website under specs. Just have heard a few people say they included the 850/1900 on the Tmo version and I hadnt seen any of the threads you are talking about can you link me to someone who has tried it with at&t??

[Phill_UK]

The only way to settle this is for someone with a TMO 9900 to check the device's 3G bands (Options > Device > About Device Versions)

If the device has 3G bands 1, 4 & 8 like they normally do, then AT&T users will NOT get 3G... just EDGE.

I understand the frequencies that T-Mobile uses are different than the frequencies AT&T uses.

However, from T-Mobile's own support page for their 9900, they state that this phone supports the following networks: 850 MHz; 900 MHz;1800 MHz;1900 MHz; UMTS: Band I (2100); UMTS: Band IV (1700/2100); UMTS: Band VIII (900).

Previously, no T-Mobile Blackberry I know of has had support for the 850 and 1900 MHz networks, which coincidentally are the same frequencies AT&T uses.

Tmo only lists the 2G bands on their website and mentions nothing of the 3G bands.

You've just answered my post

The TMO 9900 does have 3G bands 1, 4 & 8 so AT&T users will not get 3G

AT&T users will need a device with 3G bands 1, 2, 5 & 6

I admit, I may very well be misinterpreting what I am seeing on T-Mobile's website based on my great desire to have a 9900 and not being to switch away from AT&T due to my wife's insistence on having an iPhone.

However, if someone could drop an AT&T SIM card into an unlocked T-Mobile 9900 and either make me very happy or put me out of my misery, I would be grateful.

Thanks Phill_UK.

My wait for AT&T to release the 9900 goes on. . . . .

UMTS: Band I (2100); UMTS: Band IV (1700/2100); UMTS: Band VIII (900).

In my first post, I posted a link to T-Mobile's official support page for their 9900. It lists the supported networks. You can find it here: T-Mobile Support Community: Tech specs - BlackBerry Bold 9900

How bad would it be on edge anyways?

Pretty bad if you use the browser a lot, stream or do any action that requires good internet speed, like tethering, sending vids/pics, file transfer and bla bla bla.

If you just use it for bbm or plain text emails, then EDGE is just fine.

And with such a nice device with a good browser and hardware, edge is plain sad

I agree... Just wish this wasn't true!

Not sure if anyone is still reading this thread. I'm trying to figure out if there's any way at all to further "unlock" the device so that I might be able to access AT&T 3G/H+ on a TMobile 9900.

My bands are 1, 4 and 8.

To answer questions, and to describe my experience on EDGE with the device.

Its actually not bad. The faster processor does load pages (full pages) a lot quicker than they did on an old Curve. Data, such as pictures/audio, transfers at rates you'd expect on EDGE. I'm on Wi-Fi almost all day, so I'm connected to BIS. And, with that comes faster even faster download/file transfer/web page speed.

When I start the device up, it takes about 30 seconds to connect to EDGE, which is after the service displays "4G" for about 5 seconds, then to SOS and finally connecting to EDGE.

Not a bad experience, I purchased under the assumption it was an unlocked Rogers, but oh well. The fact that it shows up initially as 4G makes me think it will work, but there's something the carriers are doing to limit. I don't know though.
