[Q] What is your FCC ID?

I'm curious how many hardware variations of the Defy exist with distinct FCC ID numbers. This would be a good complementary thread to the one with all the different 3G fix files.
So please state 1) the carrier you bought your phone from (or if not a carrier, the site you bought it from), 2) the network you use it on (if not the same) and its 3G frequencies, 3) The FCC ID number behind the battery of your phone. If there is no FCC ID, then any other numbers you can find.
If your phone has the same info as another already posted here, no need to re-post.
I don't own a Defy but let's start with the info stated here:
http://www.phonescoop.com/phones/phone.php?p=2965
1) T-Mobile USA, 2) N/A, AWS 3G, 3) IHDP56LC3
I have also found FCC reports of the following variations:
IHDP56LC1: WCDMA 850/1900
IHDP56LC2
IHDP56LC4
(not sure which bands on the latter two, had trouble finding the right testing docs)

1) eBay (T-Mobile USA branded)
2) AT&T (850/1900Mhz)
3) IHDP56LC3
IHDP56LC2: WCDMA 850/2100 (FCC website, Exhibit 11 RF Exposure Info)
IHDP56LC4: WCDMA 900/2100 (same above)

Aha, good to know.
If the T-Mobile USA version (IHDP56LC3) has 850/1700/2100, it seems odd they'd have (presumably for Telstra) a hardware variant which is the same minus 1700 (IHDP56LC2). I wonder if this is genuinely different hardware or if they just fail to list the AWS band in the FCC tests?

1. Telstra
2. Telstra Next-G
3. FCC ID: IHDP56LC2

Agreed, it's seems odd that they would have 2 different hardware variants with the difference being only AWS. Guess the only way to test would be to have someone with a IHDP56LC2 Defy flash the USA fix and come over to the US to test.
This would all be easier if manufacturers started using the penta-band chips like in the Nokia N8.

Well, I have seen (on this forum?) pics of the US Defy running 3G on AT&T using the 850. If true, and the 2100 works in Europe (it does, BTW) then anyone would be seemingly better off with the US version.

Well, *anyone* but:
- Customers on global carriers who require the 900 MHz band for good 3G coverage
- Customers on any carrier that has significant 1900-only 3G areas
Which leads to a question - can anyone here confirm they live in or have occasion to visit an area where AT&T's 3G coverage is only 1900 MHz, and no 850? You can verify this by bringing your Defy as well as a phone that does have 850/1900 3G, and seeing if you get 3G on the other but not the Defy.
If you can set up this kind of situation - take a nandroid backup of your firmware, and then try applying the "3G fix" for 850/1900. Is your phone now able to get 3G on 1900? If yes, then the bands are entirely software-controlled; if no, it's the hardware.
Or to the Australians out there with a Telstra Defy - do you have access to an Optus SIM card? Can you test out the Defy in a 900 MHz-only Optus coverage area, and then try flashing the "3G fix" for 900/2100... is your phone now able to get 3G on 900?

1) Bought from T-Mobile Direct (UK)
2) Network: T-Mobile (UK)
3) FCC: IHDP56LC4

All,
I live in Madagascar, after flashing US 3G fix, i've got 3g at home now. Before fix, in rom 3. 4. 3-11, i always don't have at home. But, oh yes there's but, the network signal is very poor. And i've lost it many times.
My Fcc id HDP56LC4.
Now i'm in 900-2100 fix and everything is right but in Edge lol 2G.
My carrier is Telma, 900 for Gsm and 2100 for 3g+ (Hspda). I've signal and 3g+ connection when i leave home for office, in the city.

Hello I have purchased a Motorola Defy from e-bay off of kick mobiles in the UK it was already unlocked the FCC ID is :IHDP56LC4 900/2100(2.2.2) and I had it shipped to Canada..... much to my dismay it does not work on our basebands here..well it does on GSM 2G...anyway I found a Canadian one from Telus so i bought that one too and it's FCC ID is :IHDP56LC1 850/1900(2.2.1) hope this helps

I'm confused. When I go to the phonescoop page and click on the different FCC IDs IHDP56LCX where X is 1-4 the only one that is different is 3 where it has the 1700 band in addition to the 850/1900/2400?
I'm looking for a phone with hardware to support 850/1900 3g. can someone point me in the right direction?
Thanks,

If you want the one with 850/1900 3G, it's the one sold by Telus Canada, or in certain Latin American countries.

Thanks for the reply!
It seems really tough to pick up a defy with specific hardware because a lot of phones on ebay anyway are tmobile which apparently is 850/1700/2100 and could work with att but will not have the 1900 band or mb525 which is the international version which doesn't work with att?

For IHDP56LC2, seems to be almost all in one:

The ONLY reason for the baseband switcher is to fix firmware files that are meant for the wrong variant. The ONLY baseband you need is the one intended for your hardware. Nothing else will give you better results. The hardware cannot under any circumstances connect to bands it's not compatible with.

GSM Windows Phone 8 devices with LTE

This is only a simple summary I wanted to do about
There are many people who like to buy their smartphones from 3rd party vendors (ebay, and other on-line stores), so on.
Fortunately, there are several smartphones start with support for LTE networks

CANADA, U.S. (At&t, T-MOBILE), MEXICO (TELCEL), ARGENTINA (MOVISTAR), URUGUAY (ANTEL), PUERTO RICO (at&t), ETC.
To date are only four models of Windows Phone 8 with support for LTE networks in BC4 (the LTE Band Class 4, is the key band in many operators in America, but not to all) , whose band is used for LTE in Canada, Mexico Telcel LTE and the upcoming LTE network fron TMoUS
Should be mentioned that at&t has the license for the BC4, but not yet implemented (at least commercially), and so far at&t only uses its LTE in BC17 (the band 17 should not interest anyone outside of at&t). Even so, the at&t´s LTE devices releases are still very relevant to another countries like Mexico and another some countries in Latin America, becauser ther LTE devices that are made for at&t in addition to the band 17, also include support for LTE in the band 4, which is the band that is used by several american carriers. LTE devices from Canada work also in BC4
WP DEVICES WITH LTE IN BC4:
For now, WP8 devices supporting LTE Band 4, are:
-HTC Windows Phone 8x (check that it is the GSM version with LTE in BC4, not to be confused with Verizon´s HTC 8x, nor the global version without LTE). There are variants of 8Gb and 16Gb of storage.
-Samsung Ativ S GT-i8750 (not to be confused with the version GSM/CDMA). With variants of 16 or 32 GB of storage
-Nokia Lumia 920.2 [RM-820]. Not to be confused with the Lumia 920 RM-821 which supports other LTE bands (European and others)
-Nokia Lumia 820.2 [RM-824]. Not to be confused with the Lumia 820 RM-825 which has European and other LTE bands
Specifications:
http://pdadb.net/index.php?m=pdacomparer&id1=3808&id2=3814&id3=3914&id4=3985&id5=3906&id6=3860
At the moment, I have no information if some trick is needed to operate the LTE in another network for which it was designed, (of course, assuming that both the device and the network has the appropiated LTE band, but the smartphones mentioned meet the requirement of hardware essential to be able to function in carriers with LTE LTE in BC4
For example, so far, I know the requirements to enjoy the LTE if the device was not purchased with the operator (Telcel Mexico case for now, but can serve as a reference for other operators):
-A unlocked device, which support the band LTE 4 (or AWS LTE, which is the same)
-Being in an LTE coverage area
-A Version 6 SIM Card
-Postpaid plan
-That the operators´s system enable your cell phone line as "LTE user"
-May or may not, be needed a minor operation, as in the case of the Nexus 4 you have to enter a service menu to change settings related to LTE (like Nexus 4); or edit the APN settings (like as was done with the 3G)
Europe
In Europe, LTE bands are used:
BC7 (this is in 2600MHz) used for LTE in most countries of the EU; Australia, etc
BC20 (this is in 800MHz) some European countries already in use as in France, Germany, etc.. (although in the same territory also use BC7); Australia
BC3 (this is in 1800MHz). Only a few countries use this as LTE band are: Belgium, Denmark, Finland, etc (although in the same territory also use BC7 and BC20). Australia uses BC3 too.
WP8 DEVICES THAT HAVE LTE IN BC7, AND LTE IN BC20:
Lumia 920 [RM-821], not to be confused with the American version.
Lumia 820 [RM-825], not to be confused with the American version.
UPDATE: Added:
-HTC 8X LTE C625b (LTE BC7 and LTE BC3)
Specs:
http://pdadb.net/index.php?m=pdacomparer&id1=4039&id2=3859&id3=3858
Note: Some Latin American operators are deploying LTE networks in LTE frequency BC7, as Entel in Chile, UNE in Colombia, so they falls in the second case (European style)
sorry for my bad english

In many European countries networks are already operational on 2600 Mhz. Some countries are allowing refarming of spectrum in the 1800 Mhz range. Some have already deployed in the spectrum of the digital dividend (switch to DVB-T) at around 800 Mhz, while other countries still have not given away those frequencies. It is safe to assume that most european networks will operate on a Mix of 800/2600 or 1800/2600.
The european versions of the Lumia 820/920 to my knowledge should support all three of those bands.

HTC M9+ on VZW 700 band LTE

Hey team, surely we can figure this out. I have an M8, rooted on VZW in the USA. I am going to buy an M9+ on amazon purely for fun. On PhoneArena, it specifies that it does recieve 700 band LTE, VZW's main LTE band. VZW owns the 700MHz Upper Block C (band 13) so I believe it will be compatible, just not with XLTE, which uses band 4 (1700MHz). Just looking for someone selling one or any tricks thanks!

Don't forget that Verizon is CDMA based while the M9+ is GSM only. Even if Verizon uses SIM cards for LTE & device might not work. Also note that LTE is only used for data, so even if it did work, you'll probably not get voice calls.

Thanks! That's a great point as well. My speculation is that the VoLTE for Verizon, which utilizes the 700 band. So maybe VoLTE would still work. I'm sure an M9/M8 Sense 7 rom port could work.. Verizon also is CDMA dominant but supports international GSM. So my dinners are crossed. Comments? Questions?

I believe 4G is LTE. Weird thing is it didn't find AT&T 4G (Cricket is on AT&T). Unfortunately I can't find a way to see which bands they are.

I have used the M9+ in DC on the Cricket network and I only get 3G. I think there are ways by which bands can be unlocked. I remember having a similar thing back when I was using the One X.

I would suggest that you cancel the order if you still can. Even if it does somehow support Vz 700 or AWS band, which I strongly doubt, you won't be able to make calls since Vz use CDMA for that. M9+ probably doesn't support VoLTE either so you end up with a 5.2 inch tablet at best.

AWS should work. I route most my calling over Wi-Fi/data anyways. If calling doesn't work, I am going to use the Project Fi sim from my Nexus 6. I'm on Wi-Fi literally almost everywhere. I wonder if anyone has thought of flashing the M9 dialer over to the M9+. I've edited my scripts and got VoLTE to work for my HTC M8 with something similar. Any dev suggestions?

Is this with Vz SIM card?
Anyways, I don't think it works with any US LTE network. It probably picked up the 2100MHz downlink part of AWS in the network search. Since it lacks the 1700MHz uplink part, it can't really use it. You are better off switch to AT&T or TMO and use their 1900MHz 3G (HSDPA+, US carriers call it 4G) networks.

Its a Verizon sim out of my M8, currently active. I think it works on the LTE so it picks up the 4G network, but without the CDMA backbone it wont connect. Says it will work on any GSM network in the US, maybe flip it here in the states instead of selling it. Any root suggestions?

Thanks people, in advance, for answering my question . Thank you :* .

The Indian model should be SIM unlocked, but it might be locked if you buy it through an Indian carrier (I don't know how it works over there). The Indian model has Quadband GSM, Triband HSPA, and LTE 1, 3, 5, 8, 40.
In the US, on AT&T you'll get 2G (850MHz and 1900MHz), 3G (850MHz), and in a few markets, LTE on Band 5 (which is also 850MHz). It's missing AT&T's primary LTE band 12/17, as well as LTE bands 2 and 4, and 3G on 1900MHz.
On T-Mobile, you'll get 2G on 1900MHz and that's it. It's missing 3G on 1700MHz/2100MHz and 1900MHz, and LTE Bands 2, 4, 12.
It will not work on Verizon or Sprint at all.

The US model of the G4 Plus has Triband CDMA, Quadband GSM, Pentaband (five-band) HSPA, and LTE 1, 2, 3, 4, 5, 7, 8, 12, 13, 25, 26, 41. It'll work on all major carriers, although some prepaid carriers do not allow unlocked phones as part of their own policy.
Compared to the Indian model, you're missing LTE Band 40. If Band 40 isn't important to you, get the US model.

So i'm probably about to pull the trigger on this phone because i'm sure it'll work fine on T-mobile, but upon researching, it looks like we could be missing LTE band 66.
"When it comes to T-Mobile, we’re focused on the LTE bands 2, 4, 12, and 66, the last of which is a newer band that T-Mo will be using for LTE coverage."

As for international G950F, these sites cite bands 2, 4, & 12.. but no 66. Considering 2, 4, & 12 handle most of the coverage and that 66 is a newer band I don't think this is an issue at all. Besides my pixel has the same bands, sans 66 and I have great coverage.

I know the international S7 worked fine here in the US, but I had ATT back then. If anyone else has a G950F on Tmobile here in the US, please posts results so we can establish a consensus that LTE coverage is not an issue.

The F model supports band 66 according to the FCC filing . The sites you are using are not accurate.

Does this go the same for the FD model?

I'm still unclear as to whether or not the FCC model "G950U" is the G950F or a US carrier version, but i have read several references to the FCC model being "unlocked", so maybe it is.

FD model supports the same bands as the F model.

The U and F models are two different models.
The F/FD are international unlocked version.
The U model is the US model (locked or unlocked) and has a different FCC certification.
It also support mode LTE bands and carrier aggregation options for the US.

Not sure in F supports WiFi calling...

Does the US model support all US Carrier frequency bands? I'm curious because once I'm done paying my phone off on sprint I would like to unlock it and bring it to t-mobile. I also ask because I read that the US version of the S8 are the same no matter the carrier....

Not sure about that. Sprint is CDMA and T-mobile is GSM. Typically not compatible.

Well i'd figure any model made for the US market would have 66.. The international G950F was the one in question. And it looks like I answered my question with a little more digging. This test report from the FCC for the G950F confirms band 66 along with, from what I can see every necessary LTE band for both ATT and Tmobile. See "4.6 EUT Description" https://apps.fcc.gov/eas/GetApplicationAttachment.html?id=3292314 It also references some CDMA bands so maybe you can switch from Sprint to GSM carrier.. idk.

I too did some digging in regards to band 66 support on the international model. The phone doesn't directly support the band from my understanding but has the hardware to interact with band 66 frequencies. This in returns grants band 66 compatibility at band 42 or similar. This is just my interpretation and could be wrong but best I've come up with thus far.
edit: To help backup my claim: http://niviuk.free.fr/lte_band.php
Band 66 utilizes the 2100Mhz spectrum and according to a T-mobile rep:

955FD has band 66- BUT
The 955 FD (presume also 955F and 950FD and 950FD) has band 66. Tested on Freedommobile (Wind) Canada
BUT
If it takes a phone call it drops to wcdma band 4, and does not return to band 66 LTE.
I must toggle LTE/WCDMA/GSM to WCDMA/GSM and back to LTE/WCDMA/GSM to get band 66 LTE working again,
Your argument as to this is the fault of Freedomobile or Samsung. Some other phones but not 95xFx have had a firmware fix here on XDA.
Could a utility be written to do this?
If someone can solve this I might even root my S8+ 955FD!
