I live in USA and if i buy me unlocked i9100 s2 and insert at&t sim card in it will i at least get 3g data signals? Or will it just be 2g EDGE? ps i do have 4g lte in my area even though i know it will not work on i9100.
Youll get better help if you go to one or two of the other forums on here.....like epic 4g touch model/tmobile usa version.

maybe your an iphone expert

I don't really understand your question, if you are in USA, if your sim card supports LTE, and if your phone supports USA broadband LTE, then you can use it, why wouldn't you? If you are using the good old I9100, (not 4G model) then of course it won't, because it only supports up to 3G+.
Edit: Take a look at this thing:
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
If you purchase an international version of 4G s2, it might not work on USA too.

Hi,
I just wanna know if it will work with Bell if i buy it unlock.
The bands of the original galaxy s are :
UMTS/HSPA 850/1900
GSM/GPRS/EDGE 850/900/1800/1900
and the samsung galaxy s II :
UMTS 850/900/1900/2100
GSM 850/900/1800/1900
[Q]
What is the difference between HSPA And UMTS ?
It works on AT&T which uses the same radio bands as Bell if I'm not mistaken so yes, it will. You'll need to have it unlocked though as I'm sure you do know.
I have the HTC Radar 4G on T-Mobile. Once I unlock it and use it on At&T, it will definitely do calls, but will it pick up 3G or 4G on the AT&T network? I asked HTC and they were unsure. Thanks!
Do a search in this forum to find your answer.

AT&T uses 850 MHz / 1900 MHz for GSM/GPRS/EDGE and the same two frequencies (850 / 1900) for UMTS/HSPA (their 3G/4G service).
T-Mobile uses the same frequencies (850 / 1900) for GSM/GPRS/EDGE, but uses 2100 MHz and 1700 MHz for UMTS/HSPA/AWS (their 3G / 4G network).
If you want to know what phones will work where, compare the frequencies they receive with those of the carrier you want to use.
In the case of the Radar, it uses the following frequencies
GSM/GPRS/EDGE: 850 MHz; 900 MHz; 1800 MHz; 1900 MHz
UMTS/HSPA: 1700 MHz; 2100 MHz
So, for GSM phone calls and data you have a match with AT&T (and, of course with T-Mobile). 3G / 4G is a different story. The Radar has the T-Mobile 3G/4g bands, but not the bands for high-speed data on AT&T.
So, if you are happy just making phone calls and using EDGE data, then you can use the phone on AT&T. If you want 3G /4G as well you have to stick with T-Mobile.

I finally was able to get the h2O SIM card (AT&T service) and surprisingly it picks up 3G! I definitely notice the difference from when it goes from 2G up to the 3G speeds
http://www.htc.com/us/products/radar4g-tmobile?view=1-1&sort=0#tech-specs
Apparently. It says it does 2100/1900/1700/850
*T-Mobile only uses 1700/1900 bands. source
Interesting! I took my specs from the T-Mobile page which omits the UMTS 850/1900 band. Thanks for the correction.
The box clearly states GSM 850/900/1900/2100 AND HSPA/UMTS: 1700/1900/2100
AWS 1700 = T-Mobile, Wind, Mobilicity
UMTS 1900 = AT&T (although they use 850 extensively too), Rogers, Telus, etc
UMTS 2100 = Asia/Europe
My Radar picks up AT&T 3G. Not sure if UMTS 1900 band will be omnipresent on AT&T as a lot have been extended with HSPA 850 as well.
So, whereever you find UMTS 1900, you'll definitely catch AT&T 3G
Hope this helps.
So, will this work with the medianet plan?

YES!! Gets 6M downloads, 1.5M uploads.
According to the chart below, if I use a T-Mobile HTC One on AT&T, I would be able to use all of AT&T's HSPA+ network but will only be able to use their 700 MHz band for LTE? Am I reading it right or do I have it wrong?
I found this chart at android central (can't link because I'm blocked as a new user)
GSM/GPRS/EDGE
850/900/1800/1900 MHz
WCDMA
AT&T: 850/1900/2100 MHz
T-Mobile: 850/AWS/1900/2100 MHz

LTE
AT&T: 700/850/AWS/1900 MHz
T-Mobile: 700/AWS MHz

Does this mean that if I have a T-Mobile phone, I can fully utilize HSPA+ speeds but not LTE speeds on AT&T?

I'm wondering the same thing. If I purchase the tmobile ONE and use it on ATT, will I get LTE and MMS as well.

Someone can correct me if I'm wrong, but only if you're in a refarmed 1900mhz frequency area. You can find out if you are here: http://airportal.de/
I've been investigating this. FCC documentation suggests that the HTC One for T-Mobile is certified for LTE Band 17 (AT&T).
I've unlocked the handset, but I'm only able to access AT&T's HSPA+ network.
Out of the box, the HTC One for T-Mobile doesn't support AT&T LTE.
If there is latent support, I reckon that you'd need to flash AT&T's radio to the device.
EDIT: I stand corrected. http://forum.xda-developers.com/showpost.php?p=41237507&postcount=17
the tmobile ONE supports tmobile/att hspa and lte for both carriers. The att ONE supports lte for both but only att hspa and only tmobils 1900 hspa.

This is extremely curious to a noob like myself. To clarify, The HTC One purchased through Tmobile can be used on both the Tmobile and ATT networks? If purchased through Tmo how can I get the SIM for ATT? Can I toggle between the two? How can I utilize this awesome find to get the best out of each network. You all are smart. Thanks!

My friend has the T-mobile One and I have the AT&T One. He tried putting his T-mobile SIM in my phone, but it would not work (my AT&T One has to be unlocked, which I believe can be done if you buy an unlock code). I couldn't say if my SIM would work since my SIM is not actually AT&T's, it is a Straight Talk SIM that is compatible with AT&T's network. I imagine you could also unlock the T-mobile variant to work with AT&T's networks, but I'm not sure if it'd be able to work on the 4G network.
Hi guys,
I have a strange problem, I guess.
I bought my HTC Desire 610 on amazon. It is AT&T.
I use it in a different country with GSM sim. Everything seems to work fine. I am connected to 4G network if I am in 4G coverage zone. But when I dont, it won't switch to 3G, it just goes offline.
long story short: 4G seems to work, but 3G don't.
network mode is set to WCDMA/LTE Auto.
could anyone help?
I think this is something to do with the Rom, if you were to install the cyanogen mod or the slimkat Rom, 3g works just fine in both, idk why though

I Installed GSM signal monitoring application. As it turns out the phone only receives HSPA+ (3G) signal, but somehow thinks that it is 4G. Because 4G is displayed on top of screen. that is why I thought it was working on 4G network. but now I guess it works on 3G but thinks that it's 4G
now I want to enable 4G but have no idea how

Depending on what country you are in 4g probably won't work with an at&t phone as the different variants have different 4g bands unlocked in the radio firmware and probably antennas. See the following extract from desire 610 network specs. US 4g bands are quit different from those available in most regions.

Its hard to say for sure. Try a ROM from the region your in or cm11 which is for all regions. This probably won't work but is worth a try. Otherwise to that you would have to go s_off with sunshine (costs $25) and flash changes to radio firmware( either someone's dump from a phone in the region your in) or modifying it (google "XDA qcom unlock radio bands) but either way it's very risky unless you really know what you doing you can easily end up with an expensive brick and it still depends on whether you phone is equipped with a suitable anttena for the frequency the band your carrier is using.
I have a new unlocked S9+ China (SM-G9650/DS, Qualcomm Snapdragon 845), and I'm trying to figure out if it is fully supported by T-Mobile in the US. I've done some Googling on this, but I'm not sure I understand the results. The supported band specs for the phone, and the T-Mobile frequencies used, are below.

It will work on T-Mobile frequencies but you won't get Wifi Calling or voLTE. The stock CSC is TGY - Hong Kong, T-Mobile is TMB. I haven't found any way to change the CSC even with custom ROM, but assuming one became available you would trip Knox and lose Samsung Pay, Samsung Health, Secure Folder, OTA Updates and Factory Warranty. Some members have posted in regards to changing the CSC Code in the link below but I'm not certain it's working out. Good luck!

baring any unforeseen hidden stuff, you should be good to go for Tmobile...Minus the new Band 71 on the 600mhz spectrum. Honestly, unless you live in the area that will get this deployment, this shouldn't be of concern. As long as you can use Band 2/4/12, you will be ok with Tmobile.
I almost went with this route as well since I wanted to get a Snapdragon version with larger storage size. But I chickened out because I've been reading people having bad signals/not having full LTE speeds with their imported S9+ on TMOUS.
Good luck and let us know!
