Okay I been asking this for a while. I will be taking a trip to Mexico in July and I'm getting a prepaid sim there. I choosen which company to go with while I'm down there and I wanted to see if I'm able to get 3G with Movistar Mexico while I'm there. I will be running the Venasuar rom with the GSM patch. Here's a link of Movistars network stuff. Thanks for the help guys

You won't be able to get data... You need the 2100 MHz band that carrier has the 1900 MHz band

Actually, he will get Data, its just that its gonns be on EDGE instead of 3G/HSPDA

CDMA: Dual-band CDMA/EVDO Rev. A (800/1900 MHz)
LTE: 700 MHz (Band 13 only)
GSM: 850/1900/2100
And in this case, GSM means 2G/Edge, not HSPA... so no 3G.
Technically, the MSM8660 supports a much wider range of frequencies, but the Rezound does not have all the "tuning" or radios (software radios) needed to make them work properly. This isn't something that the Snapdragon unlock hacks can make work either, as far as any users here have tested since the frequencies are not disabled in the chipset, they just were never setup in the firmware to operate.
GSM ≠ 3G/HSPA/HSPA+

I've seen this blog.

However, with our experience in the industry we have seen that almost every device launched in recent years within Europe has been ‘optimised’, with the American 850/1900 range locked down, leaving only 900/2100 for the rest of the world. As we are based in the UK it is for this reason we have taken the tentative step of advertising only these frequencies.

yeah, UK clove store said EU galaxy S2 doesn't support US 850/1900
network. (They said that may be US 850/1900 UMTS frequencies are locked.)
But, I find google news.
http://www.mydaily-gadget.com/news/5718-att-getting-samsung-galaxy-s2-gt-i9100-fcc-says-i-do
Speaking about release dates we do not have a specific one for the GT-i9100 in the USA but we can confirm the FFC has authorized the use of this particular smart phone on the 850MHz and 1900MHz GSM frequencies which means the first carrier to offer the Samsung Galaxy S II might be AT&T. These two frequencies account for the AT&T 3G network but they also match some Canada operator’s frequencies so there is a big chance the Galaxy S II will land there too in the near future.

That first link (that I provided earlier tonight I think) - read it to the end please, Clove has all the info on that page, just finish reading it. sorry for the tone , but I think you did not pay enough attention - there are comments to that blog post that say clove confirmed with the manufacturer and local distributor that all 4 bands are present.
I'm confused here
I have SGSII ordered from Clove. I plan to use it with ATT sim card. Have I made a mistake? Will I be able to use it? Do I need to cancel?
I hope it works well with AT&T since I intend to get this phone.
My current (imported) GT-i9000 did not properly support AT&T and has very poor call quality and call drop issues.

Although Clove originally said they doubted it would support 850/1900 3G+, they did later confirm their stock would be quad-band 3G. So no need to worry about support for NAM 3G.
Once someone get's the GS2 in USA on ATT, can you confirm that it indeed works on Edge AND 3G?

That's because the i9000 is only tri-band UMTS and only supports AT&T's 1900 frequency. When it gets to an area where the 1900 H/3G signal is weak, it can't switch over to the 850 UMTS simply because its hardware doesn't support it. So, then the phone call drops. You'll notice if you switch the i9000 to 2G/Edge, you'll never get a dropped call... because it's quad band GSM.
Also, ever notice you never get dropped calls when stationary and on H/3G? That's because with a solid 1900 UMTS signal, the i9000 will never search for the unsupported 850 band.
(And yes, I have confirmed all of this as I also own an i9000.)
i9100 supports quad-band UMTS with 850/1900 H/3G, so you will not have the frequent dropped calls anymore.
Here are the frequencies for AT&T: http://en.wikipedia.org/wiki/AT&T_Mobility#Radio_Frequency_Summary
Frequencies used on the AT&T Network
850 MHz GSM/GPRS/EDGE 2G
1900 MHz GSM/GPRS/EDGE 2G
850 MHz UMTS/HSPA 3G
1900 MHz UMTS/HSPA 3G
700 MHz LTE 4G
So, the i9100 International will do almost all. Except LTE.

Sorry I pressed thanks instead of quote.
No, its nothing to do with the modem. If it was, people all over the world would be buying devices from other countries.
The fact is the international GSM version only works on the frequencies its designed to work on. This is a hardware limitation and no amount of software will resolve that.
International frequencies are different to USA frequencies and as such, devices not designed for the USA will not work to their full potential in the USA.
UK (international) uses 900 Mhz/1800Mhz GSM/3G where as USA T-mob uses 1900Mhz GSM and 2100Mhz 3G.
Because the International GSM quad band device is:
850/900/1800/1900 MHz...
The GSM and 2G function works on 1900 (T-mob) but has no way to use 2100 for 3G as its not physically possible

yes i agree for international version.. but if you read closer i DONT have the international version but the att version.. and as far as i know all the usa versions are the same with just diff. modems.
The international version will work in areas where T-Mobile is refarming 1900mhz to 3G. However this is only happening in parts of the coasts. I'm using it in Ohio and getting EDGE only. That said, it isn't too bad.

Erm, it's being tested in some coastal areas, but the 3g/hspa+ over the 1900 band is slated to go live on the majority of the network by the end of the year.

I purchased a Tinji i9300. I have been working on this for over 3 weeks. I have no service with T-mobile. It recognizes my SIM card as T-mobile. In Engineer Mode, my bands are, EGSM900, DCS1800, PCS1900, GSM850, WCDMA-IMT-2000. I have tried numerous ROMs (stock and custom) and have rooted the phone. I have changed the IMEI. No service at all. Any thoughts? Band issue? T-mobile issue? Possible solution? **** out of luck? :crying:
Thank you!
I was looking at the Google Play Edition S4 on the Play Store: [Can't link outside post yet but go to the Google Play Store]
According to the Specs it uses the same frequency ranges that Verizon uses:
Network
Unlocked GSM/UMTS/HSPA+/LTE
GSM/EDGE/GPRS (850, 900, 1800, 1900 MHz)
3G (850, 1900, 2100 MHz)
4G LTE (700, 850, AWS, 1900 MHz)
Would this thing work on Verizon with their sim card? Sorry in advance for sounding like a noob.
It lacks a cdma radio.

It will (presumably) work on Verizon when they do Voice over LTE... but until then, yes, it lacks a CDMA radio which means it probably won't be of use for VZW.
I knew it wouldn't work on non-CDMA networks but what about the LTE side of the house? Verizon uses 700 Mhz and 1700/2100 Mhz LTE bands for 4G. I could live without 3G for a phone that could connect to any carriers LTE freqs.

Might be fine for 4G data over LTE, but will probably be a paperweight as far as calls are concerned unless you want to go the VOIP route... not to mention you'd be SOL anywhere there's no 4G coverage. Basically there would be no fallback, you'd either have 4G data, or nothing.
I think AT&T and VZ use different ends of the 700mhz spectrum, so even if the phone somehow got authenticated onto the VZ network, the radio/antennae for AT&T's 700mhz may not work on VZ's.
I got a chance to purchase the vzw gs4 for $250 under a one year contract for very good plans
Wondering if the contract expires, will i be able to use other gsm carriers?
AFAIK, i545 should come unlocked and can be used on att hspa and tmo lte(band4), am i right?
Just wondering if i545 has lte band 17 for att, or has anybody tried putting an att sim to i545 yet?
Another question I know verizon is notorious for not pushing timely system updates, but how far are the custom roms from the 9505g rom?
Thanks for your input
i saw in the 9500 dev section somebody wasn't able to enable tmob lte for this model which seems wired
has anybody tried att sim card?

A simple search would tell you that many of us have used non-VZ SIM cards. The phone is SIM-unlocked.
Here's the bands that the Verizon S4 has:
LTE 750 / 1700
WCDMA 850 / 1900 / 2100
CDMA 850 / 1900
GSM 850 / 900 / 1800 / 1900
[from http://www.phonescoop.com/phones/phone.php?p=4066 ]
T-Mobile uses 1700 for LTE, so there appears to be a match.
For AT&T, 700, 1700, 2300 for LTE. 1700 is the common band.

samsung listed i545 to have LTE band 4 which is 1700/2100

OK, so here's a reliable source - Samsung. http://www.samsung.com/us/mobile/cell-phones/SCH-I545ZWAVZW-specs
LTE: Bands 4/13 (Band 4 is 1700 MHz, band 13 is 700 MHz)
CDMA 1x/EVDO Rev.A: 800/1900MHz
HSPA+/UMTS: 850/900/1900/2100MHz
GSM: 850/900/1800/1900MHz
I don't understand the various 1700 MHz band allocations, so I can't say if Tmo's band 4 is compatible with VZ's band 4 radio.
"Hack the radio" meant enabling radios that were built in to the phone which VZ disabled. I don't think that's the case with the VZ S4.

as far as I know there aren't various 1700MHz allocations. In such case, every allocation must have their own band, like Band 2 and Band 25. Both of them are in the 1900MHz but with diferent allocations.
So any LTE Band 4 enable device should work in any LTE band 4 carrier.

It's actually CDMA/GSM and LTE. Sprint locks down the GSM portion against using a domestic SIM from AT&T and TMobile by default. They'll unlock it for international SIMs/use if you meet certain criteria etc.
It has the necessary radios to work on Tmobile and or AT&T, you just have to have it unlocked a certain way. Search here on XDA, it's been done though it's not the easiest process.

Every LTE device will have a sim slot.
LTE is based on GSM technology. Now with that said there is a GSM variant and a CDMA variant. The CDMA variant does not have the basic GSM chipset for GPRS/ EDGE technology. So putting your sim card in there MIGHT only get you LTE in a re farmed TMO area with 1900mhz. Bottom line is if you want the phone to work like it should you need to buy a T-Mobile one.. It has the 1700mhz aws band you need for all of T-Mobiles network.
