Phone not getting full coverage or bars. - Galaxy S6 Edge+ Q&A, Help & Troubleshooting

I bought a Sm-g928a sim unlocked, but I use t-mobile service. The tmobile and at&t use the same bands except for the 900 mhz range.
Tmobile version:
LTE Cat9 700/800/850/900/1700/1800/1900/2100/2600 (Bands 1,2,3,4,5,7,8,12,20)
At&t version:
LTE Cat9 700/800/850/1700/1800/1900/2100/2600 (Bands 1,2,3,4,5,7,12,17,20)
Every or 4g lte band is the same in att version, but I don't get full bars. Close as I get is 3 to 4 bars, and there is a major difference in coverage. I travel a lot in CA, my note 5 gets coverage everywhere even in rural parts of the state. Edge plus drops all signals in rural part of state.
I'm I missing something or does the 900mhz band, do the outer limits of service?
Does tmobile use the 900mhz band in CA?
Any suggestions on how to fix this?

same issue, sprint variant with t-mobile

I have the T-Mobile version, on T-Mobile and in I lose connectivity. It's annoying.

[Q] question for 3G frequencies in Canada

I have a tmobile vibrant phone (hardware only). According to the phone specs i SHOULD be able to get 3g signal with my fido sim card since the phone seems to support all the same frequencies as the Canadian i9000.... but i only get edge.
If you guys are getting 3G with fido or rogers sim cards, did you have to set anything special in the phone settings?
Thanks!
Vibrant T-mobile 3G runs on 1700
that is why you only get EDGE (2G)
Fido, Rogers & Bell runs on 850 & 1900 for 3G
On my way to work today this is what i saw in the network box.
inside my house - EDGE
Outside my house - 3G
back country roads to work - i saw just G or no signal (normal i loose signal with my iphone and blackberry on there)
at work - back on edge
So i DO get 3g somehow! or is it just teasing me by showing 3G?
i read somewhere that the t-mo vibrant does have 1900 as one of its 3g bands, so this is why your phone has been able to pick up 3g at times. the problem for you is that rogers/fido mainly use the 850 band. i had the nokia n97 mini that had the 1900 but no 850 and while driving around most of the gta i would get 3g, but when i went into buildings, houses, etc, it would drop to edge.
Maybe your phone supports 1900 and not 850 MHz? Or the oposite? That would explain why you would get bad UMTS coverage.
@hondaguy you were faster than me

To my knowledge the T-Mobile Vibrant does not support the major Canadian 3g bands. It is quad band 2g, which is why you are able to get edge but it is only 2 band 3g, at least according to this spec sheet:
http://pdadb.net/index.php?m=specs&id=2439&c=samsung_sgh-t959_galaxy_s_vibrant
T-mobile uses the 1700 and 2100 UMTS bands for 3g, Bell/Rogers/Telus/Virgin/Fido use 850/1900 UMTS bands for 3g. Therefore the 3g radio on the Vibrant is not compatible with these networks.
However, WIND mobile uses the 1700/2100 UMTS bands for 3g and you can use unlocked T-Mobile phones to their full ability on Wind's network. Wind is only in major urban centres though so this may not help you if you're not in the city. Hopefully you are as Wind has a pretty sweet unlimited data plan!
http://shop.windmobile.ca/
On the other hand according this this article from Engadget:
http://www.engadget.com/2010/08/22/confirmed-galaxy-s-unlock-codes-are-stored-in-your-phone-vibra/
If they're right that the Vibrant is somehow capable of AT&T 3g, it would mean the phone has to be tri-band UMTS: 850, 1700, 2100 (or 1700,1900,2100) as AT&T uses the 850/1900 bands like Rogers/Bell/Telus.
This doesn't make sense to me why T-Mobile would do this. The 850/1900 bands are really only used in North America on competing carriers, so it doesn't give the phone "world" capabilities, the 2100 band does that. Why they would add a feature who's only purpose is to make the phone work on competitors' networks is a mystery to me but Engadget seems to have a picture that confirms it. If this is true than an unlocked Vibrant should technically be able to work on Rogers/Bell/Telus/Fido/Virgin 3g, but only if it is unlocked. I'm pretty sure that T-Mobile sells their phones SIM locked to their network, have you unlocked yours?
~Edit if it does have 1900 as the third band the above posters are correct in that you will get minimal 3g coverage as 850 is the primary in Canada.
yeah i wanted to switch to Wind Mobile for the $35 true unlimited data plan, until i found out they don't work with normal 850/1900/2100 phones
only 1700 / 2100

[Q] Which Network ????

Hi All
I am visiting the USA in September for holiday and am doing a bit of travelling while i am out there. I was going to buy a prepaid sim to use with my SGS II which is sim unlocked. I am visiting Los Angeles, San Francisco and Vegas what network would you guys recommend for coverage and costs ?? it would have to be a GSM network.
Thanks
I would say T-mobile because they have a awesome pay as you go plan
I would say T-Mobile
T-Mobile and AT&T are the only ones compatible with your SIM. However the SGS2 is only going to get EDGE on T-Mobile if you're wanting data. It's compatible with the HSPA for AT&T however. From what I understand there really isn't a difference in price between the two for prepaid. Nothing to make a difference when you're taking an international trip anyway.

European 3G bands are different than US ones. In Europe the UMTS band is operating on 2100MHz. AT&T operates it's 3G service on 850 and 1900 MHz.

Yeah but the SGS2 has the 1900MHz band in it, so it would work on AT&T's 3G network, but only on T-Mobile's EDGE.

You need both bands for AT&T 3G. 850 provides downlink. 1900 provides uplink. In Europe, 2110 is downlink and 2150 is uplink. It is normally just included in one spec of 2100MHz. The 850MHz band in this device would only provide 2G speeds.
AT&T is your best bet.

[Q] S4 SGH-I337 or SGH-I337m? AT&T or Rogers?

I spend 50% of my time in the US and 50% of my time in Canada and have a contract with both AT&T and with Rogers.
I am going to buy the S4 soon. Should I get the SGH-I337 variant with AT&T or the SGH-I337m variant with Rogers?
In about 14 months, I will be back in Canada (on Rogers) permanently. So far, I am leaning towards the AT&T variant due to greater rom availability, but I am worried about whether the S4 will work on Rogers 3G bands and LTE network.
The reason I am worried is that I am currently using an unlocked Sprint BB Tour 9630 Quadband on Rogers with specs:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 2100
CDMA/EVDO Rev A 800/1900
And the Roger's EDGE network barely functions on that phone (many disconnects).
I am a little unfamiliar with network bands, but can you let me know if the phone's 3G radio and LTE radio are identical across Rogers and AT&T?
I read somewhere that Rogers S4 uses 2600 MHz LTE Band and AT&T uses 700 MHz LTE. Is this true? Or does this phone have both LTE bands built in?
Thank you!

[Q] Which note 3 for these connections

I need a note 3 that can:
connect to AT&T LTE here in the USA
And connect to T-Mobile NL in Holland
And unlocked bootloader
ATT:
850 MHz CLR 5 UMTS/HSPA+ 21Mbit/s 4G In service

1700/2100 MHz AWS 4 LTE 4G In service Additional LTE band for more bandwidth in select markets
1900 MHz PCS 2 LTE 4G Service starts by the end of 2013 Additional LTE band for more bandwidth in select markets[31]
2300 MHz WCS 30 LTE 4G Approved for deployment in Oct 2012[32]

TMO:
This company uses GSM1800 as their main frequency band for communications. In 2010 T-Mobile Netherlands had some problems with 3G capacity, but after investing in the network modernization they have managed to deal with this problem. So now they provide 3G services using 2100MHz band
Click to expand...
Click to collapse
Am I restricted to the N900-T? or is there another one you know of.
sorry for the noob question i don't know about all the bands.
Thanks!
T-Mo NL uses the 900Mhz for 2G, 2100Mhz band for 3G, and are in the process of updating to the 900Mhz band for both 2G and 3G. (Should be finished by the end of 2016.) LTE runs on the 1800Mhz band. (I can dream these numbers by now...)
You can find the bands per phone version here: http://forum.xda-developers.com/showthread.php?t=2574886
Does the TMo US version even work with AT&T?
Both N900-t and N9005 work in terms of frequency for 2G.
You will probably not be able to use the N900T for 3G once the network upgrade is finished here, as we're going to be using the 900Mhz as the main frequency for 3G. The N900T can't see that one. The 2100Mhz will be serving as a bandwidth increaser, not as the main band.
There's a chance you won't get 4G everywhere on the N9005 when using it in the US, as it can't see the 700/1700/1900/2300Mhz frequency.
And you're going to have to root to get rid of the region lock either way if you want to use both SIMs.
Tmo version 4G will not work with AT&T 4G. I tried with my wife's phone
T-Mobile (US) devices support the same frequencies as AT&T devices. This is coming from experience and from the fact that I've pretty much memorized all the band numbers that carriers use and phones support.
If you want a Note 3 that supports AT&T LTE in the US and HSPA+ in NL, you can either get the AT&T model or the T-Mobile model. The T-Mobile model supports one extra band (1700 MHz HSPA+) that is only used on T-Mobile US (nowhere outside of North America), so it wouldn't make a difference. Just know that it CAN be used on AT&T. The other differences between the two:
1. The T-Mobile version supports Wifi Calling (if used on T-Mobile), AT&T model doesn't.
2. AT&T removes the "Network Mode" menu from the Settings menu (so you can't force EDGE for example).
3. AT&T version has a locked bootloader. T-Mobile version doesn't.
In many instances, although 900 MHz WCDMA/HSPA+ isn't listed, it's supported. I can't confirm it because I'm in the US, and GSM carriers use (total) 850/1700/1900/2100 MHz for WCDMA, not 900 MHz. I think it's just unlisted to discourage people from exporting the US models. The only LTE frequency that North America shares in common with Europe is 2600 MHz, which is supported by the phone. I believe that's only used in urban areas in Europe.
Overall the T-Mobile model is the most open in terms of bootloader and supported frequencies (though either model would work in your case).

OnePlus One Carrier Compatibility

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.
