Hi folks
I just moved to the US (about a week ago) and was wondering why my mobile internet connection is so slow.
I have a SGS2 factory unlocked and i was fine with it in Germany (no problems with 2g or 3g speed)
Now I'm in the US with a t-mobile prepaid card which should give me 3g speeds , if not 3g at least EDGE Speed. But the only thing i get is the E-sign with 2 arrows which is friggin slow.
As far as i know t-mobile's 2g & 3g frequencies should be the same as in Europe.
So my question: Is my phone the problem or is it just that the 2g/3g coverage in San Diego is so bad ?
thx in advance
its normal...coz sgs2 does not support t-mobile 3g bands....but it does support at&t 3g bands....i am also using t-mobile prepaid plan...and dont use data that much...coz everywhere i go i have wifi....

ah ok thx for the reply
do you happen to know if an factory unlocked iphone (without sim lock bought directly from apple) will be able to use the US-3g bands as well as the European ones ?
as far as i know....it will be same as sgs2....only supports at&t 3g bands.....no t-mobile.....
Ok thx man.. Guess I gotta ask them directly then

Asking who directly? T-Mobile USA? You can ask, won't change the answer. If you want 3/4g in the US with either a European Galaxy S2 (GT-I9100) or an unlocked iPhone, you will need to be on AT&T.
T-Mobile doesn't use the frequencies that those two phones support.

E-sign = EDGE.
So if i buy me i9100 s2 and i put at&t sim card, i live in texas USA will i get at least 3g signals?

USA uses different bands from the rest of the world because, well, idk
North America:
GSM: 850/900/1800/1900 MHz
CDMA: Band Class: 0/1/10
WCDMA: Bands: 1/2/4/5/6/8/19
LTE: Bands: 1/2/4/5/17/19/25/26/41
Rest of World:
GSM: 850/900/1800/1900 MHz
WCDMA: Bands: 1/2/4/5/6/8
LTE: Bands: 1/3/5/7/8/20
This might be the case here, i don't think its carriers fault but idk really.

I moved to Australia this week. I brought my MoPho with me. It was a hassle getting it to work but i figured it out and thought to tell you how it went. I put a Vodafone AU SIM card in my phone but 3G would not work. I knew for a fact i was in a coverage area for 850Mhz 3G so I was pretty annoyed it would not work. Turns out with the Photon you have to manually ass the APN for Vodafone and probably a few others. I was able to get all the settings I needed from here.

tl;dr Sometimes when abroad you need to manually add the APN for the carrier.
I need to do that for my carrier too (Slingshot NZ, 850/2100Mhz) but after that it works fine, 3G GSM data is borked on the current ICS build though.
Ya. Im going to wait awhile before i put on another custom ROM. Still trying to get used to everything in Australia. Cant risk being without a phone. Im going to keep an eye on cm9. Until then i only have the precious data connection on my phone which is caped at 4GBs :'(. I miss unlimited.

Well. Thats a tricky question. Bellow i will list the different networks and what they support compared to the photon. Currently all three major carriers can provide 3G to the Photon. Telstra simply has a better network but it has nothing to do with how it interacts with the phone. For both Optus and Vodafone so far i have had to manually set the APNs. It was a ***** with the Optus one because of the separate APNs for internet and mms. Even though optus doesnt have umts850 and the photon doesnt have umts900 i am downloading about 4Mbs in East Killara (Suburb by Sydney) throught Optus' 2100 single band HSDPA+. I have not tested Telstra because they are so freaking expensive.
Photon supports:
800/1900 MHz (EV-DO Rev. A),
GSM 850/900/1800/1900 MHz,
UMTS/WCDMA 850/1900/2100 MHz (HSPA+ at 14.4 Mbit/s)
OPTUS/Amaysim: (I only recommend for when time is being spent in Capital Cities that support 2100 single band)
GSM - 900/1800
UMTS - 900/2100 (2100 single band)
TELSTRA:
2G - 900/1800
3G - 850/2100 (850 is NextG)
LTE - 1800
Vodafone:
2G - 900/1800
3G - 850/900/2100

vodafone's 3g did not work for me at all, apns could not be set,
after a bit of hassle i got optus working and am happy so far, vodafone is sooo bad in aus anyway.
Yea i used my sprint touch pro 2 all last year down under.
Hoping the photon puts my tp2 on the shelf.
I agree with hodie though
Optus is good when your in Melbourne, sydney, perth,etc.but i thought telstra had the better overall service.

3G issue
Hi,
Im from Dominican Republic and I got a Photon, the phone use to works fine with my carrier, but since 2 weeks ago the 3G network is unavailable. My carrier is Claro Dominicana (GSM 850 MHz) and searching for the possible problem I think that one of the motorola update block that band since is the same one as ATT. I had rooted the phone and try with custom roms and also restore it to the stock rom but with no luck. Does anyone have face this issue? Is there a solution for this?
Thanks.
Hi, I have the white s2 i9100unlock version and when I put in my
Tmobile Sim card it says that I am running on E network instead of 4g. Is there anything I can do to change this? I contact Tmobile and they say it's the phone not their line. Please help me out because running on the E network is very slow

The international i9100 does not support 4G. Only option would be to get a 4G enabled one.
its because the international galaxy s2 doesn't have the same 3g bands as T-Mobile (assuming you are T-Mobile USA). They run off of 1700/2100 while the phone itself supports 850/900/1900/2100. While only the 2100 band matches, if you don't get 2100 coverage in your area, you will default to 2g.

So you started another thread on this, where I also answered your question. This phone will never get HSPA+ speeds on T-Mobile USA - or what they call "4G". It lacks one of the necessary frequencies for it. It will only get Edge speeds. From what I remember on how T-Mobile USA's network functions, 3G and "4G" need both 1700 and 2100 mhz to function, as it uses one frequency for download and the other for upload.
EDIT: Here's the wikipedia article on AWS, which is the band T-Mobile uses for 3G/4G. In brief, AWS uses 1700 Mhz for uplink, and 2100 Mhz for downlink. So since it only gets half of the band, it won't do "4G".

Unfortunately, the bolded/underlined part is simply not true. T-Mobile USA needs your phone to be able to get both 1700 mhz and 2100 mhz UMTS frequencies to do 3G/4G. If your phone doesn't have one of the frequencies, it won't do 3G/4G at all, and fall to Edge (2.5G).
What if I overall another ROM? Will it help?

No. The phone simply doesn't have the hardware to receive the frequency. Nothing you can do to fix this.

Wow that's weird, here in aus you only need to match one freq to get 3g. Do you know what t-mobile has done to require two bands to match? (its just my curiosity asking)

You need Galaxy2 HD LTE to access 4G. That particular model is not available outside Korea at the moment. If you want 4G, try Samsung Galaxy Note or LG Optimus LTE - also known as Nitro HD, or HTC phones.

That indeed is weird and inconvenient, but I guess telco's can setup their system however they like... It may have lot to do with number of people using mobile services. In OZ we have 22 million potential mobile users using 4 major telco companies, whereas in USA, they would get most of OZ population just in New York city, let alone rest of the country.
Ah systemcrasher I think they might be load balancing the hspa+ mimo across the two freqs. Telstra nextg doesn't need to coz there's allot less people here.
If that's the case still should be allowed to fall back to a non mimo mode.
Let this be a lesson to the OP, always research all carrier pre requisites before buying, also consider other carriers encased you'd like to stay open to other options.

So the answer is the link to the wikipedia article in my quote above. It's not T-Mobile USA's doing per se - they just purchased the AWS-1 (also known as UMTS band IV) band of the spectrum. That's just the way this band is set up. Wind and Rogers in Canada also use this band.
I have a INTERNATIONAL Samsung Galaxy S2. I am going to be travelling to the states soon. I am planing on getting the ATT Go Phone 50 dollars unlimited plan. My other option is tmobile. However i know they use AWS for their 3G connection but my friend is saying that their HSPA+ 4G network uses the 2100Mhz band. My question is could i use this network with my phone?
Thanks

Nope. Not how AWS works. AWS requires both 1700 and 2100, as it uses one for uplink and one for downlink. So if you go w/T-Mobile USA, you will be limited to Edge data speeds when not in range of wi-fi.
The other option you have is using one of the smaller networks that piggy-backs on AT&T's network, like h2o.
I don't know much about them though.
Hey guys, just about to trade and get one of these, I just want to know if it can work in the UK because At&t is USA based. Will my O2 sim work in it by using the app from the market which carrier unlocks it?
No comments about my username please

It'll probably work but I don't think o2 supports the 3g bands our phone uses so you'll be running on edge

thanks,
I searched up o2's 3g bands and it came up with, 850,900 and 1800.
The samsung galaxy s2 i777 model bands: Quad-Band 850/900/1800/1900 MHz, 3G EURO/AT&T AND 3G Network HSDPA 850 / 1900 / 2100
So it could possibly work. I don't use 3G much anyway, I only get 2g in my area and at school I get HSDPA. Might ask the trader if i can trial the:
a) sim
b) network connection bands

Just might have to make sure you are not in a 1900 mhz band area

Just FYI, only ONE of the frequencies need to match for you to get 3G, they don't send out one frequency at a time.
hi i have recently heard that since the ics update the droid razr is now a world phone. does this mean i can use my phone with a tmobile sim?
thanks

Good question did you ever get a reply on this?
O think it only supports overseas such as the e.u. and all. I think you would only get 1x data no 3g

DROID RAZR - UNLOCKED *DOES* WORK ON T-MOBILE USA and WIND MOBILE and V-TRON CANADA
Late thread revival... meant to respond to this one months ago! Whoops!
Anyway --- YES! This WILL indeed work with T-Mobile if you get the proper unlock code!
This has 4 different GSM frequency bands and 4 different UMTS frequency bands.
This means that you will get T-Mobile GPRS / EDGE coverage everywhere, T-Mobile 4G coverage in areas that are rolling over to 1900MHz as well as 3G roaming on AT&T in 850 and 1900MHz areas where T-Mobile doesn't have native coverage (Wausau, WI and Appleton, WI are two examples I can think of offhand)
Of course, you won't get LTE coverage, but you will get HSPA+ 4G / HSPA 3G and EDGE / GPRS on T-Mobile USA and Wind Mobile in Canada.
I'd like to try this.
Has anyone had verified success at this? I'd like to try if possible.
