Hello there. Some of the Vibrant users are not from the USA, just like me. Here we don't have the 1700 band that T-Mobile uses, but we still use 2100 MHz for 3G.
Well, demetris_I has told me that there are much better modems for us european users from devices like the I9000. The problem is that CM7 is not able to make those modem work. At least, this is what he told me.
Flashing those modems (that are compatible with our Vibrants) makes it impossible to connect to 3G. We know that it's a software problem, so it would be fixed if a developer is kind enough to investigate the way to make CyanogenMod use the correct bands.
This is a request for any of you with dev skills to have a look into this. We are very good testers, so any change you do could be checked.
Please, have into account that we are absolutely alone in Europe, we are only a low percentage of the Vibrant users, but we really need to have a better modem that fits our networks.
Thanks a lot and I hope to have a lot of answers to this. Please, don't forget us.

You need to be specific. Based upon your post, there is no way to identify what to begin working on.
1. What modems are you trying to flash?
2. Be specific.
3. What are the results you are getting? "doesn't work" isn't an answer. Does 3g connect? No? Does 2g data work? Do you get voice calls?
4. Be specific.
5. The Vibrant comes out of the box with UMTS Band I (2100mhz) support. Do the default T-Mobile radios work on non-CM7 Roms?
6. Be specific.
Hi.
Let me clear some things up.
Modems from other phones work, but only on gsm basebands.
WCDMA is not connectable until we flash any Vibrant modem.
Well this is the whole idea,
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 1700 / 1900 / 2100
Those are the bands supported by the vibrant.
So we should be able to connect to WCDMA (2100)as we are able to connect to GSM(GPRS), with other modems.
So Vibrant CM rom refuses to connect to WCDMA 2100(Europe) but gladly connects to GSM Bands (900/1800 tested) and i think is a rom specific support problem.
We need a capable developer to test and fix this issue by just looking at the Captivate/GalaxyS code git for specific changes that dont reflect on the vibrant code from the same git.
Example:
Code tells the phone to look for WCDMA to 1700 but as we flashed the phone with a different modem the initial req is not given so the phone stucks at no signal.
If you flash back a vibrant modem signal checking code executes right and proceeds to connect to next available signal that is 2100.
Sorry for the delay. I was at work.
demetris gave a very good explanation of what it happens. The fact is that the Vibrant's hardware can connect to 3G using HSDPA 1700 / 1900 / 2100.
When the Vibrant is using a modem made for it (Vibrant with Vibrant modem) you can connect to every band it does support.
When a modem from I9000, Fascinate, Captivate,… is flashed, everything works as expected, so I think they are almost identical in functionality, but SOMETHING makes it impossible for it to connect to any of the 3G bands.
When in the dialpad you enter the code to select bands, you can see/select the bands you wish to use, but it just refuses to connect.
Why do we want this working? Because for sure, modems from the european version (I9000) might be optimized for our networks and be less battery consuming or have increased coverage. demetris tested them and noticed an improvement.
So, we are asking you to look into it so modems from the I9000 (priority) becomes usable for us.
I hope to be specific enough this time. Of course, I offer myself as a beta tester. My carrier uses WCDMA 2100 MHz for 3G (UMTS).
Thanks in advance and don't hesitate to ask us!
Hey everyone!
I've been looking on the OnePlus forums lately, and lots of people have questions about carrier compatibility with the One. Personally, carrier compatibility is the biggest factor when it comes to buying an unlocked phone, so I decided to make this thread to help guide people with compatibility with their carriers. According to OnePlus's website, the bands that are supported are as follows:
GSM: 850, 900, 1800, 1900MHz
WCDMA: Bands: 1/2/4/5/8
LTE: Bands: 1/3/4/7/17/38/40
Now, I am going to start with USA compatibility. If anyone else would like me to add compatibility with their carrier, please reply to the thread, and I'll see what I can do. Hopefully, this will benefit all members of the community.
USA
AT&T
2G/EDGE/GPRS : Supported on both 850 and 1900 MHz bands
3G/UMTS/HSPA : Supported on both bands 2 and 5.
LTE : Only supported on bands 4 and 17. Bands 2 and 30 are not supported; however, they are usually only deployed to create extra bandwidth in high capacity areas. Band 17 is AT&T's major LTE band.
MVNOs of AT&T : Straight Talk, Net10, AIO
T-Mobile
2G/EDGE/GPRS : Supported on both 850 and 1900 MHz bands
3G/UMTS/HSPA : Supported on both bands 2 and 4 ("4G" HSPA+)
LTE: Supported on currently deployed Band 4. However, T-Mobile plans to deploy Bands 2 and 12 to extend coverage. So, if you have LTE signal now, you're okay. If you don't, then you most likely never will with the One.
MVNOs of T-Mobile : MetroPCS, Ultra Mobile, Lycamobile, Straight Talk, Net10

How to figure out whether AT&T or T-Mobile would be best for Straighttalk?
UNITED KINGDOM
It'll work fine on:
EE (Bands 3 & 7 supported by OPO)
Partially:
Three (Band 3 supported, Band 20 isn't by OPO. Band 20 people say will be used for rural areas)
No LTE:
O2 and Vodafone (Both use Band 20 which isn't support by OPO)
3G will obviously be fine however.

You check the coverage map in your area for each of those providers. The one with better service in your area is the one to go for.

I have the Samsung Galaxy Light SGH-T399. It works on T-M's current LTE 1700/2100MHz (band 4), but also 700MHz (band 17), which T-M just purchased from Verizon. A few other newer T-M phones are also made to work on this 700Mhz band. It seems that they were planning ahead.

The OnePlus One also works on this 700HMz (band 17) frequency.
Good news for those lucky enough to have LTE with T-Mobile. The 700 band penetrates buildings better, so you'll have a better signal inside Wal*Mart or if you live deep inside a large apartment complex.

Very true. T-Mo will probably use this band to expand coverage, Good catch :good:
However, it should be worth noting that T-Mo plans to cannibalize (AKA "refarm") its EDGE network into LTE. This may sound great; however, this EDGE that they will be converting will be broadcasted on the 1900 MHz spectrum (Band 2 LTE). The OPO will not support Band 2, so OPO users on T-Mo will not be able to take advantage of LTE in many rural areas and markets.
Will the phone work in India? Vodafone is my carrier.
Portugal
2G - Full compatibility with Optimus, TMN and Vodafone
3G - Full compatibility with Optimus, TMN and Vodafone
LTE - Compatibility on 1800MHz and 2600MHz frequencies which should cover big population agglomerates on Optimus, TMN and Vodafone. 800MHz left out, so outside cities (and probably inside buildings and small cities) it will most likely revert to 3G.

Curious, was this written by OnePlus's P.R. team? Because it really downplays what I consider one of the biggest problems with this phone, namely that it is missing half the LTE bands used by AT&T, the biggest OPO-compatible carrier in the U.S.
The argument, "Oh but they're barely deployed", is pretty weak. The fact is the bands ARE deployed, and they're only going to get deployed more because carriers aren't exactly in the business of wasting their valuable licensed spectrum. In high traffic areas where they're in use I assume it would be pretty desirable to have them because the other two bands might be over capacity, or maybe they aren't even operating on the tower you're hitting.
Everyone seems to be brushing this off. I guess it's OK to settle after all?

I agree, the lack of proper LTE bands really are a turn-off for this phone. Just look at our friends in Europe, whose widely-deployed LTE Band 20 is not supported. I'm not saying that the LTE bands here on AT&T are optimal, but it's worth pointing out that it could be worse. The fact that the One supports Band 17 should be satisfactory for many users; it's AT&T's low-frequency band, so theoretically, it should cover the most people. The higher frequencies would only make sense being deployed in areas with mass congestion. So in cities, it's fair to assume that you'll get lower-than-average LTE speeds.
Now, it could be worse. Take a look at T-Mo users (like myself). We're pretty much getting screwed over. Band 4 LTE, the band that they're using now, is very high frequency. Building penetration sucks. Coverage and range sucks. Their network currently is weak. The new bands they are deploying will be lower frequency, so they should provide more coverage and reliability. However, of course, the OPO doesn't support them, which is a major blow to T-Mobile USA customers.
But hey, for $300 for an amazingly-spec'd phone, we have to expect that some compromises had to be made.

Any specific carrier?
What about The Netherlands?
Carriers:
Tele2
T-Mobile
KPN
Vodafone
Finland:
All operators (Elisa, Sonera, DNA).
2G 900,1800MHz are both supported
3G 900, 2100MHz are both supported
4G/LTE Channels 3(1800MHz) and 7(2600MHz) are supported. Channel 20(800MHz) is not supported
Lack of support for channel 20 will limit LTE only to densely populated areas.
So I'm not the brightest with the different frequencies etc... What I do know is that Band 12 on T-Mobile has greater building penetration, and that it's currently not supported on the Nexus 6P, despite the phone having the band. My question is, what functionality do I lose? Aside from having more penetrating power, which gives me better signal, do I lose anything else? Honestly, I'm pretty sure Band 12 isn't even in Columbus, Ohio (where I am) yet... but I don't wanna buy this phone and then Band 12 go live here and then I lose LTE, if that's even what happens... or would it just resort to the current band 4?
Band 12

Thats trouble for you. From what I understand there is a long certification process to get the certification from T-Mobile, especially if they do not sell the phone. The Nexus 6 DOES support the T-Mobile band 12:
Unlocked devices
The following unlocked phones not only support LTE band 12 but all other bands required to be compatible with T-Mobile network (LTE bands 2, 4 and 12, HSPA+ on AWS and 1900 MHz, and GSM on 1900 MHz) however band support is not the only requirement. T-Mobile issued a statement regarding band 12 unlocked phones: All Band 12 LTE devices on our network must support VoLTE, E911. Currently only three unlocked phones supports VoLTE and band 12:
Nexus 6 XT1103 (US model)
iPhone 6s A1688 and A1633
iPhone 6s Plus A1689 and A1634

well tmobile has already confirm the 5x/6p will work on their network... im just wondering what the lack of band 12 support (for the time being), means for me. i assume i would continue to run on the band 4 that i do now.
Not sure if you've found the answer to your question or not. If you dont have Band 12 where you're located then its really a moot point. I'm in Phoenix and there is a TV station still operating on the 700Mhz Band 12 spectrum so I dont have it. However, if T-Mobile lights up Band 12 and these phones havent received their certification then they will not use Band 12 at all. That means you're limited to Band 2 and Band 4 LTE. Assuming you dont have Band 12 in your area (it appears you do not based on the de-facto map that most cite reference to is here http://www.tmonews.com/700mhz-lte-map/), your coverage will remain the same as it is now.
That being said, Google has stated that they are working with T-Mobile to have the 6p certified by the time the devices ship. So if that holds true, and T-Mobile rolls out Band 12 coverage in your area you should theoretically get better indoor LTE coverage since low-band spectrum travels farther and has an easier time passing through obstacles like block walls. Until then, you should have a similar coverage experience to what you have now. You're not "losing" anything to answer your question.
I had previously flashed the original radio for the 6p to have band 12 on T-Mobile. It worked great. My phone would switch from band 4 to band 2 and band 12 when necessary. Now that I'm on 6.0.1 and the new radio also uses band 12 my phone stays on band 12 only 90 % of the time. My question is for T-Mobile subscribers. Have you noticed this or is it just me? Being on band 12 primarily slows my lte speeds significantly. Another question I have is can I flash back to the older radio that permits band 12 usage while on 6.0.1? That radio was much better for myself. Both radios do show that they are using carrier aggregation when 12 and 4 are available. But I rarely see singularly band 4 or band 2 alone. I use the Lte discovery app to check what band I'm on. Almost Always band 12 and the Lte speeds prove it being only 5×5 deployment. Thanks to anyone who responds with true knowledge of checking this on their phone

You can flash back to a previous build to get your old radio back, just grab a copy of the factory build and use the radio image from that.

It's just you. I find that I only connect to band 12 when band 4 gets around -120dBm or worse, then switches back to band 4 when it gets stronger again.
