AT&T compatibility

Hello everyone! I'm wondering will this device work with AT&T service since it's just a triband phone, and, afaik, AT&T uses 850MHz as their primary frequency for GSM calls (depends on location) in NYC area.

Coverage maps are here:
http://www.gsmworld.com/roaming/gsminfo/cou_us.shtml
Specifically the 1900Mhz map is here and you can zoom in to your area and see: http://www.gsmworld.com/cgi-bin/ni_map.pl?cc=us&net=be
[You can probably also find them some place on the AT&T website.]
Be aware tho that the diamond only does 3G at 900/2100, but AT&T use 850/1900. That means you won't be able to use 3G capabilities on AT&T anywhere.
I would either wait for the american version, or buy the 2G one they're selling in india for ~200$ less.

Thanks, man! Maybe i'll look at T-Mobile plans, looks like device will work with them

Well looking at the page it looks like T-Mobile have even less 1900 coverage (GSM). I don't know their current 3G situation, but they will be/are using 1700Mhz for 3G, which the diamond can't handle either

[q] tmobile 4g

First, I'm a flashing newbie, and still have the stock ROM and Radio flashed on my Touch Pro 2.
TMOBILE has now updated(via some secret behind the scenes update) their Touch Pro 2 owners to "4G" coverage in the Detroit metro area. I would like flash to some of the ROMS offered but I'm not sure if after doing so will I continue to receive TMOBILE'S 4G coverage. I understand that "radio" flashing is separate from Rom flashing but is anyone sure that just flashing the ROM would not effect the TMOBILE 4G update.
Any help or insight is greatly appreciated.
Thanks

Does the TP2 hardware even support 4G? That's not something you can just "upgrade". Are you sure that they're not just offering more bandwidth via HDSPA? If that's the case, then what ROM you're using will have no effect on that seeing as nearly all custom ROMs have it on by default.

Got a screenshot of your TP2 showing 4G?

from my understanding, only the touch pro 2 from europe and japan have the 4g hardware, usa only 3g hardware, thats why i bought mine from taiwan so when 4g comes out, im well equipped!!!

T-mobile doesn't have 4G coverage in the US...despite their claims.

what they are actually doing is claiming their 3g network as 4g. its hspa. they took a card from verizon that considered their 2g network to be 3g. "you mean, alot of our 3g network is slower than atts 2g? and the only bits that are fast enough to keep up have less coverage than their 3g and is still slower? nonsense! i choose not to believe!"

T-mobile is marketing the same network even when they say 3G or 4G because it's all just upgrades, the appropriate term should be "3.5G". all of their sales reps i've encountered don't know anything about their network or their devices.
a week before the G2 came out, one of the reps tried to tell me that it was sporting a "dual-core processor". i laughed and corrected him without missing a beat. just watch their commercials...it's sad to see someone advertise 4G when it's just "3.5G".

Actually, it's HSPA+, not HSPA, T-Mobile & Sprint are advertising as 4G, which is faster & only a select few devices support the new HSPA+ speeds. So, it's more like 3.75G. HSPA+ provides HSPA data rates up to 56 Mbit/s down and 22 Mbit/s up. Future revisions of HSPA+ support up to 168 Mbit/s using multiple carriers. Regular HSPA maxes out @ 14 Mbit/s. The TP2 & most of HTC's 3G/HSPA(+) devices only support 7.2 Mbit/s down, 2 Mbit/s up. So, to answer the OP ?, If the network in that area was slower than 7.2 Mbit/s down before the upgrade, you will see an increase, but it'd be maxed out at 7.2 Mbit/s due to device limitations. As this is a Hardware issue, ROM doesn't matter other than the fact the lighter ROM's runs faster & therefore can get higher speeds because of the extra free RAM/Resources. Whereas, heavy, more feature rich ROM will tax the device more & therefore the CPU/RAM/Etc. won't be able to attain max bandwidth. It's like having a 30 Mbit Cable/DSL connection on a Pentium 3 PC. It'd never get the max speed as the system is just too slow to take advantage of it.
So basically, their advertising maybe false, it is used to explain a faster network & used to simplify which devices support this new speed. Most consumers wouldn't understand all this. So instead of dealing with, "why doesn't my 3G phone get full speed? *cry*" from customers not understanding their device has a limited bandwidth. Think of it like the days of dial-up modems. ISP A has a 56K network, but User B has a 28K Modem, so User B only gets 28K speeds.
"A 4G system is expected to provide a comprehensive and secure all-IP based solution where facilities such as ultra-broadband (giga-bit speed such as 1000+ Mbit/s) Internet access, IP telephony, gaming services, and streamed multimedia may be provided to users."

So it goes something like this;
2G -> EDGE (2.5G) -> 3G -> HSPA (3.5G) -> HSPA+ (3.75G?) -> 4G (?)
Also keep in mind it's measured in bits per second, not bytes. There's 8 bits per byte. So 8Mbit/s = 1 MB. Also some service providers cheat by counting it as 10 bits per byte. (b=bit/B=Byte)
EDIT: Interesting side note, according to gsmarena.com, the G2 & MyTouch 4G only supports HSPA 14.4 Mbit/s down & 5.76 Mbit/s up (T-Mobile's network is 21 Mbit/s according to reports) & the Evo 4G only supports Rev. A, up to 3.1 Mbit/s.

Any Tmobile G Note owners in the LA California Market Area??

I was wondering if there were any imported G Note owners in the LA California Market area that could test a situation for me...
I just came off of a 1 hour phone call with T-mobile tech support, they have told me that in the LA Market area they ARE INDEED running 1900mhz HSPA+ as of November 2011. They claim that the GNote should be capable of pulling in data on this band with a regular Tmobile SIM and entering the proper APN settings into the phone. I had this confirmed by a level 3 tech support agent and a supervisor, also from level 3 tech support.
If this is true, then we should ALSO be able to receive data on the 1900mhz band once the AT&T roaming agreements go into effect at the beginning of the new year.
Anyone who could verify this by actually using a Tmobile SIM and using the correct APN settings, your info would be much appreciated.

Well I am not in the LA area, but I would gladly test it. Although I have no idea how to change the APN settings.
Also, does this mean they are planning on supporting 1900mhz everywhere in the near future, hopefully?

T-Mo migrating their 3G over to 1900mhz makes a lot of sense really. Had the AT&T-Mobile deal gone through, their plans were to phase out 1700mhz AWS in order to make way for LTE using the same frequencies anyway. Since that failed, AT&T and T-Mobile are basically going to achieve the same thing through roaming agreements, but in order for that to work, they need to be fully compatible with each other. So, either AT&T needs to start supporting AWS 1700 compatible hardware, or T-Mobile needs to start phasing out AWS 1700 3G in favor of 850/1900 3G instead in order to be compatible with AT&T. The latter seems more likely to be the case, especially as that would mean that AWS 1700 could be freed up to allow T-Mobile to (maybe) roll out their own LTE network someday.

I can tell you in a few days when my SIM arrives, I live in that general area

[Q] AT&T nokia 920 on T-mobile

So without thinking I bought a Nokia Lumia 920 for AT&T off of Ebay.
Now after doing some research I see I may not be able to get 3G/4G.
So I have two things to ask, would flashing another rom on my device help? (I really don't think it will but i'm going to ask to be safe)
Or is there anyway to get 3G/4G working without having to buy a new phone -_-

T-Mobile obtained a bunch of bandwidth that AT&T was going to use, after the failed acquisition attempt. They've used that to roll out network coverage for AT&T's phones, as part of their plan to encourage people to switch. It's not as *extensive* of coverage as T-Mobile's native bands, but it's not terrible. You probably can't get LTE, but you can get 3G and HSPA+ (what TMoUS often calls 4G, especially before they had their own LTE).

I know I get 4G and LTE on T-Mobile using an AT&T 920, but I think LTE only works in certain refarmed areas that use the right frequency. HSPA+ (4G) and 3G appear every once in while and work as well.

I can deal with that, I know back in the day when i unlocked my wife's Iphone 4 it could only get edge. but I was not sure if that problem was just because well it was an Iphone.

sweet thanks for the info.

Yeah, old iPhones used AT&T's frequencies for 3G and T-Mobile uses different frequencies, so you couldn't use 3G. That's not much of a problem anymore, though; even phones that don't support T-Mobile's main bands can use their re-farmed AT&T bandwidth.

T-Mobile refers to it as refarming; that is assuming you have coverage and that's a big if for many of us who are rural and you live in a town big enough to have it then if you're using an AT&T device subsidy unlocked or locked then you will be able to access HSPA+ and I'm not kidding when I say it's fast, faster than both AT&T and Verizon Wireless in Auburn-Opelika, AL and Columbus, GA where I hail from. HSPA+ is not a LTE or 4G technology so it will run on both AT&T and T-Mobile's 1900 band...if AT&T it's HSPA+ everywhere and where T-Mobile has refarmed 1900; it's 3G or 3.5G there too. Otherwise, it's 2G and I can safely tell you it sucks once you've enjoyed HSPA+ and worse T-Mobile has next to no coverage in many places outside most big cities and that's the wrap with T-Mobile.

lumia icon hspa over 4g?

So after the denim update, AWS (aka 1700/2100 or LTE Band 4) support for the icon(929) became available, and because of this I purchased the Icon and I love it. However I live in Canada and have a month to month plan with Mobilicity. I guess I didn't do my research well enough (I'd like to think the internet was a bit misleading but....i guess its matter of perspective). Mobilicity solely rely on the AWS band frequency. They don't offer LTE but instead use HSPA . I knew that already but I figured that since AWS was supported I could receive HSPA signal over the 4G radio but nope I was wrong.
So I guess there are enough distinct differences between HSPA on AWS and LTE on AWS enough for them to be not cross compatible? Is this a hardware "issue" or a firmware/software one that I could do something about? Is it possible to enable 2G/3G/HSPA over the 4G radio? Or maybe I can get it to work by setting the APN correctly? I looked at some phones specs over on GSMArena which do offer HSPA + LTE support over AWS, I really want to say that it seems unlikely that 2 or more pieces of hardware are required to offer 2 services on what is essentially the same frequency.
