Rogers SGH-i727r question - Galaxy S II Q&A, Help & Troubleshooting

Hi all,
I'm currently agonizing over which version of the SGS II to get (international, LTE, or Nexus). I was playing around with my girlfriend's new SGH-i727r (Rogers LTE version) this morning and noticed something interesting on the debug menu - it clearly lists all 5 WCDMA bands:
WCDMA 850
WCDMA 900
WCDMA 1700 (!)
WCDMA 1900
WCDMA IMT2000
I suspect this is a pentaband phone, even though it's not advertised as such.
Thoughts? If this is true, it would be a huge plus in its column, as the screen and pentaband are the two biggest features of the Nexus I'm interested in.

German SGS2 in the US?

Heya
A buddy of mine, who's located in the US, is hunting for a SGS2.
One idea was, I buy one here (=Germany) and send it to him.
Question: Will the german SGS2 work fine in the US with his US sim card?
He mentioned something about "boost" or "sprint" being the carrier he has a sim card of.
Of course the device would be unlocked and all, so that wouldn't bother us.
If it your buddy has a "Sprint" network contract he needs a 4G/CDMA phone. Sprint has a specific version of SGS II called "Samsung Galaxy S II Epic 4G Touch" (SPH-D710) .
2G Network CDMA 800 / 1900
3G Network CDMA2000 1xEV-DO
Announced 2011, August
Status Available. Released 2011, September
Hmm, but that'd mean he'd need special FWs/ROMs and couldn't just flash all the ROMs and stuff floating around here, right?
What carrier/network/whatever would he need to be able to use a "normal" I9100?
delete....
Samsung Galaxy S2 (international) has support for
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1900 / 2100
Samsung Galaxy S II T-Mobile
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 1700 / 2100
but I believe T-Mobile also suport HSDPA 900
AT&T: Samsung Galaxy S II AT&T
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1900 / 2100
Sprint: Samsung Galaxy S II Epic 4G Touch
2G Network CDMA 800 / 1900
3G Network CDMA2000 1xEV-DO
So the international SGS II should work best in AT&T networks. And maybe in T-Mobile. For data 3G network is important.
3g will not work on t mobile with international version... don't mislead people. In order for 3g to work on t mobile both 1700 and 2100 freq must work... one is used. For upload and the other download.

Thanks guys! This helped, I think.
Looks like he should get an AT&T SIM and all shall be fine

3G tri-band or quad-band

Title pretty much says it all. What's the real story on the the 3g frequencies? Nokia's site indicates it's quadband 3G, but yet many of the stores seem to indicate that it's tri-band for 3G. I would like to get one for use on ATT, but I definitely need 850MHz 3G since that is the predominant frequency in my area.
Anybody? What's the real answer on this?

This only adds to the confusion (No WCDMA 850)?
Thanks for the responses everyone. I think they just add to the confusion on what the real answer is, or Nokia is producing multiple models with different frequencies which I've seen referenced elsewhere.
I might just hold off for the 900 or wait until CES in January where they are supposed to make their big splash for the U.S. market. The render of the Lumia 900 that hit wmpoweruser today certainly looks nice if it's true. I wouldn't mind a slightly larger screen if it doesn't make the device too large. Some of the current phones border on mini-tablet size!
I know of two types of Lumia 800's and you can differentiate them via their FCC identification.
The European edition, FCC ID: LJPRM-801:
GSM/EGSM : 850/900/1800/1900
WCDMA : 900/1900/2100
The North American edition, FCC ID: ...RM-819:
GSM/EGSM : 850/900/1800/1900
WCDMA : 850/1900/2100
I really wish Nokia would fix the data on their web pages. I ran into this a few years ago with another phone I purchased from them where it was advertised as having U.S. bands when in fact it did not. Thanks for the info everyone.
Agree 100%. When i bought my phone, the lumia was advertised as:
WCDMA: 850/900/1900/2100
Many sellers have since correctly identified which bands the phone supports, but some still falsely advertise both 850 and 900 bands being on the phone.
When my Lumia 800 arrived and I could only get Edge/G service, I did some research and I was slightly disappointed. Luckily I work and live in a Wi-Fi zone, so that is my primary data connnection.

You too, huh? I was curious about Rogers. I find that 2G isn't the end of the world.. Only shortcoming are media rich sites, otherwise they still load up quickly for me.
The only thing I really would have missed on 3G is mapping and navigation, but the non-data GPS and preloaded map feature has completely eliminated that concern.
Rogers here in the 'Peg. I'm in love with it even though the primary service around my home is Edge/G. However, since I wrote that piece above, I grabbed the "Nokia Network Setup" application from the marketplace and now I can get 3G around my workplace.
Here is my situation at the moment. I'm currently in the US using At&t's network through straight talk. I purchased the Nokia Lumia 800 the UK version which is LJPRM-801. It clearly states that it supports WCDMA 900/1900/2100. Which I suppose are really meant for the UK or Europe. When I purchased the phone from the seller he clearly stated it was lock and he got it from Orange UK. Which I assume is locked as well. Surprisingly when I received the phone I inserted the Sim and it registered perfectly fine. I get voice AND data. I figured it may possibly be using the 1900 band for data. My main thoughts about this UK version is it may possibly have the 850 band included but not listed on the box for regulation concerns. How would I go about and truly testing it out if it does support 850 band?
You can't really, short of going to an area you know uses soley 850Mhz 3G, and not 1900 as well.
I dont see the reasoning behind manufacturing two different phones, My thoughts are they could have just disabled the band with a simple firmware. Has Anyone truly tested this? Any though on getting a different firmware version of the Lumia 800 on this UK version seeing if it would enable the 850 band.
Me too I purchased one from Clove.co.uk. On the box it stated 900/1900/2100 for 3G but I have 3G. Maybe I have a 1900Mhz station near my work. I will do more tests tonight.
Does an app exist to know the current band of 3G connection?
I've called Nokia while in Germany and they said that they only produced quad band Nokia lumia 800's

When you say quad band are you referring to 2g or 3g? because we know it's quadband 2g, but whether it's quadband 3g is the question.
So I have used it on 3 different locations here in Montreal on Rogers and I always got 3G. I don't know the band used by Rogers. I found several references but not definitive answer. I have the Lumia 800 Model 801.

Both 2g and 3G
So you have the lumia 800 which has quad band 3g? If possible could you please post a picture of the lumia 800 box listing the quad 3G bands?

I'm in Germany right now and don't have the box. I don't remember if it had the cell bands on the box. I know I got hspa on AT&T and I was happy.

[Q] Can I replace my Exhibit ii with SGSIII on tmobile walmart 100m/unl data plan?

I am thinking about trying to get an sgs iii and wondering if it is possible to get it on the $30.00 mo 100min unl data plan through walmart?
I have the exhibit ii on this plan, had it for a couple months, anybody know how I would do this?
If it will work with Tmobile band why not, best to ask the source. I don't think we have a Wal Mart rep guru here.
Sure you can, if you don't want 3G.

You have prepaid plan, you can put your sim into just about any unlocked GSM phone (and T-Mobile phones) and use it. If you want a good phone right now, get the Galaxy Nexus (GSM), it supports T-Mobile 3G (1700/2100 band). T-Mobile version of SIII will be coming later.
thanks for the responses, a Galaxy Nexus is probably a more realistic option than the sgs3 price wise, going to take a good look at it on the play store.
cheers.
T-Mobile and AT&T both support compatible band.
the SGS3 uses HSDPA 850 / 900 / 1900 / 2100
T-Mobile uses HSDPA 900 / 1700 / 2100
AT&T uses HSDPA 850 / 1700 / 1900 / 2100
now we play match the bands. we see at&t shares 3 bands with the international SGS3, thats great. T-Mobile shares 1, not as awesome, but 1 band is enough.
its true what theyre saying up there about "only having 2G", well i should correct myself, it WAS true. however recently T-Mobile has upgraded their 2100 band to 3G, as theyve been expanding. so it will work fine on Walmart's plan, as they use T-Mobile's network.
T-Mobile will come out with an SGS3 later in the year, for SGS2 it was 6 months behind the international version. the T-Mobile version will use HSDPA 900 / 1700 / 2100. what do more compatible bands mean? well it means if youre in an area you normally wouldnt get good 2100 band signal, you may get 1700 signal. if you live in the city, youll see no difference at all, its only when youre in rural areas.
so in short; you can totally use the i9300 SGS3 on tmobiles network, and yes, you will have HSDPA 3G

Could really use a source for this, please. Everything i've looked up has suggested that their HSPA+ is only 1700 and 2100, and that phones with only 2100 would not work.

you know what, i made a mistake, i was using this
http://support.t-mobile.com/docs/DOC-4261
looking at the bands the T-Mobile One S (along with all other tmobile phones) support, but the 900 band is just added to the phone so it can be used if taken abroad. so my mistake.
to reiterate the sgs3 will only work on 2g on tmobile, it will only work on at&t for 3g.
im glad you questioned it, i would have gone along giving bad information

Question regarding 1700mhz band

So I read around that the hack for the Samsung Galaxy Note I717 to get the LTE 1700mhz frequency working on T-Mobile (U.S.) and Wind/Mobi (Canada) is available.
My question is, would this or any hacks work on any LTE1700mhz band phone to work on AWS carriers running on HSPA mode?
Like the HTC One X AT&T version for example..
3G Network HSDPA 850 / 1900 / 2100
4G Network LTE 700 MHz Class 17 / 1700 / 2100
which is the same specs as the Note in terms of bands it uses...
Anyone knows??
MT4G running SyNthetic_aospX BR7

Can someone help with HSPDA phones ASAP

Hello everyone,
I am thinking to purchase at&t or T-mobile samsung galaxy S3, samsung galaxy s3 mini, iphone 4, 4s or 5 immediately before I go back to my homeland. I know these samsung galaxy S3 and iphone support HSDPA network. My homeland has only WCDMA 2100MHz network. My question is will these galaxy S3 or iphone works on WCDMA 2100 Mhz network. Thanks in advance.
HSDPA is the data connection protocol for 3G networks. WCDMA is what 3G is called, and 2100 MHz is the frequency. You need to look at a full specification list for the carrier variant of the phone you want, and check that it supports 2100 MHz frequency band. You'll see this info and supported 2G and 3G bands right at the top of the specification list in GSMarena. If the phone supports 2100 MHz, then it will work in your country. HSDPA/HSUPA is to WCDMA as GPRS/EDGE is to 2G GSM networks. They are just data protocols. You need to look at the bandwidth specifications.
