I9100 cdma capable? - Galaxy S II Q&A, Help & Troubleshooting

I live in the US and was wondering if the i9100 would be capable to use cdma for verizon, sprint or cricket? Im wondering because when you go to mobile network it says gsm only, cdma only and gsm/cdma.

No.
And under mobile network, it actually says:
GSM/WCDMA (Auto mode)
GSM only
WCDMA only
WCDMA =/= CDMA.
Click me for info on WCDMA.
Long story short, WCDMA is 3g/"4g" (4g in quotes, because it's HSPA+, which isn't REALLY 4g) used for data on some GSM networks (AT&T mostly) in North America. Not the same as CDMA used for voice on some networks (Verizon, Sprint, Cricket) in North America.
Confusing, I know.
EDIT: FYI, this is a GSM phone; the only network in the US that you will get full use of all the capabilities of the I9100 is AT&T. You CAN use the phone on T-Mobile USA's network, but will only get Edge data speeds, as its hardware is not capable of receiving the necessary 3g/4g network frequencies for high speed data on their network.

Questions about AT&T 3G network settings

Hey guys, I just got my new HTC hero. I'm with AT&T now and having the unlimited 3G data plan. I setup the configurations of APN settings as following:
Access point: wap.cingular
Username: [email protected]
Password: CINGULAR1
But I only see an "E" at the connection status which I believe indicates EDGE. Can anyone tell me how to get 3G work on this device?
Thanks a lot!!!
I didn't realise the hero was out in the us yet but if it is i don't know why and if it isn't out its because i don't think it surpports american 3g networks i think you can only get 2g.
Yes I got this phone out of the US.
So you mean there's no way at all to get 3G to work on this phone with AT&T or any other carriers?
In its current state the phone does not support the AT&T bands for 3g.
There are rumors of an AT&T version coming October 11th, that would support 3g.
European/Asian version of this phone does not work with US 3G. AT&T's 3G network requires the bands 850 & 1900, while T-mobile's 3G requires the bands 1700 & 2100. European/Asian version supports only the bands 900 & 2100.
Does this mean T-mobile 3G may work on this phone?
T-Mob's 3g should connect to this phone, if you could find a signal, haha.
http://www.androidauthority.com/index.php/2009/07/03/htc-hero-approved-by-the-fcc-with-att-3g/
Neither T-Mobile US nor AT&T will work with this phone for 3G. The only version of this phone that exists at the moment supports ONLY European 3G. There are rumors of the device coming to AT&T, but nothing confirmed. IF that happens, the new phones would work, but that wouldn't change the fact that the device you have will still only function on Edge.
Sorry to be the bearer of bad news, but it's true.
It's actually Sprint pal. Also, there was a picture for Tmobile also (this appears to be a rumor).
T-Mob uses the 2100 spectrum so i dont see why it wouldnt work.
And a CDMA and a GSM (With AT&T 3g bands) has gone through the FCC recently.

No, it won't work with t-mobile USA's 3G network.
Yes, T-mobile in Europe use the 2100 band for 3G so the Hero works. But T-mobile USA use 1700 and 2100 bands for 3G, and you need a phone that support BOTH bands to connect to its 3G network.
Unfortunately, unless T-mobile USA decides to carry this phone (and they have already said that they wouldn't), there won't be a version of Hero that support its 3G network. This is because T-mobile USA is the only carrier in the world that uses the 1700 band for 3G. You may ask why T-mobile uses different bands for 3G in different countries. This is more of a regulatory decision than a business decision. If you are interested, go read about those FCC spectrum auctions.
All in all, European/Asian version of the Hero won't work with any 3G network in the US. The product id of the European/Asian Hero is HERO100, it supports only the bands 900 and 2100 for 3G. There will be a North American version with product id HERO130 that supports the bands 850 and 1900. It will be released either on AT&T or on the Canadian carrier Rogers, because only these two carriers use these bands for 3G. Currently it is not know whether it will be on AT&T or Rogers, but that latter is more likely IMO. Finally, there will be a CDMA version, with product id HERO200, for Sprint. This is more or less confirmed to be coming in October.
T-mobile US 3G uses 1700 for down and 2100 mhz for uplink. So 2100 alone isn't enough as you need both directions to connect.

Thanks! That was very informative, although it totally crushed my dreams of owning a Hero while remaining on the T-Mobile network.

[Q] Is Telus a GSM Network now?

I know telus used to be strictly cdma, however i know as of 2010 they have made some upgrades.
Does anyone know if unlocked phones such as this one:
(add http) cgi.ebay.com/MOTOROLA-DROID-MILESTONE-2-ANDROID-SMARTPHONE-UNLOCKED-/140483114173?pt=Cell_Phones&hash=item20b57234bd
would fully funcionall work on telus?
Just by looking at the supported bands it won't work on Telus or Bell. It will only work on Rogers but at EDGE speeds. The current supported bands by Telus and Bell are 3G only which are 850/1900 frequency. The only other provider in Canada which has a different one is Wind which is on the AWS 1700 frequency so T-Mobile 3G phones should work.
Telus and Bell Canada are not GSM because that refers to 2G which is a legacy network they do not have. They are 3G which all the 2G providers such as AT&T have upgraded to. Their CDMA network is still there running in parallel for now.
They use the exact same 3G system and frequencies as AT&T. So any AT&T 3G phone will also work on Bell or Telus. They do not have the legacy network so 2G phones will not work. Only 3G phones.
To put it another more technical way:
They support 3G UMTS/HSPA 850MHz and/or 1900MHz
They do NOT support 2G GSM/EDGE on any frequency

[Q] Is it possible to run three networks ie GSM,3G,4G in the same rom

Is there a way to use all 3 networks because 4G is now in my area and it would be nice if i could use that network for better speeds. But it seems that most roms are either GSM and 3G or 4G and Wimax is there any solution?
I don't think you understand the question your asking.

If you have a 4G capable GSM phone in America on a carrier such as T-Mobile or AT&T you can have 3G and 4G
If you have a 4G capable CDMA phone in America on a carrier such as Sprint or Verizon you can have 3G and 4G/LTE
GSM means the phone uses a SIM card.
CDMA phones don't use SIM cards.

In Australia we have Vodafone,Optus, etc that offer 2G (GSM) and 3g (WCDMA).
But Telstra Australia's biggest carrier now has 4G as well. I thought that maybe to access this new network I was restricted by the rom I am using, not the sim card. Because of the two different type of roms ie GSM and CDMA. Or is all controlled via my carrier?

your "4G" isn't really 4G, it's 3.5G.
It's still HSPA (WCDMA), just a faster version and your phone already supports taht. It will say either E(edge), 3G or 4G/H+
IF it is LTE that you are talking about Telstra getting, the 3vo does not support that network, there isn't an LTE radio on the device so no possible way for you to access it.

[Q] Radio?

I know the Jetstream was designed to be run on AT&T and Rogers, but I am curious if it is possible to flash a radio to enable usage of T-Mobile's HSPA network, much like the Samsung Galaxy Note has been enabled to, as seen here.
Can any of the amazing Devs out there shed some light on this?

jdavis08, Simple answer is yes. It is a standard 2G / 3G / LTE (AT&T / AWS band) phone. So you can use it on ANY 2G / 3G / LTE network with a SIM. But you may need to break the SIM Lock on any handset.
Just wanted to clarify. The Jetstream is 2G/3G/LTE /capable, 2G (GSM): 850/900/1800/1900MHz, 3G (UMTS/HSPA): 850/1900/2100, and LTE: 700mhz & AWS-1700/2100.
Currently, T-Mobile only uses the AWS for their HSPA+ network, not LTE (from what I understand, AWS will be transitioned for LTE and 1900mhz refarmed for 3G/4G early 2013) - and if I'm not mistaken, the HSPA+ is only supported by the "3G" band of this device, not the "LTE"
So - to make a long story short. I am a T-Mobile subscriber with various "4G" phones from T-Mobile. Their 4G only works if the phone has a radio with AWS for HSPA as T-Mobile (unlike AT&T) does not use the 1900mhz for their HSPA (yet). I own this tablet.. It has been SIM unlocked and it simply does not get anything above EDGE... and I live near and visit major cities in Washington State, Seattle/Bellevue/Tacoma, which definitely have TMo's 4G coverage.
I know I should just cool my jets until TMo rolls out the network upgrades, as I have no interest in joining AT&T. I was just curious if there was some way to "trick" the phone to use the AWS frequencies for HSPA, like the Galaxy Note has been made to do as the radio specs are identical.
I know that the Note was enabled to do this by flashing another radio. Support is minimal for the Jetstream these days... so I was just reaching out.
Thanks guys

4G Data on an unlocked S2?

Hello,
I have the international phone of the S2. I am right now running on T-Mobile's service. I can call, sms, and mms just fine. But its on the EDGE network for data. If you root the phone (which I have done before), will I be able to force the phone to go into a 4G network like HSPDA? T-Mobile is a GSM network, however T-Mobile's required bands (1700 and 2100) are not listed in the GSM bands but on the HSPDA bands.
You can force the use of WCDMA without root access by dialing *#*#4636#*#* selecting phone information and then WCDMA only from the drop down box.

I selected WCDMA only, but for some reason, it automatically switches back to auto mode. Should I reflash the modem?
Umust have selected Preffered... Use WCDMA only
Peace
Hit Thanks & It will Disappear

even if you force the phoone to use UMTS, or HSDPA, you probably still won't see 3G (or what t-mobile call 4G), until they refarm their 3G network to 1900 band in your market (or you could be one of the lucky few that are in those refarmed market already).

If you are using the international variant of Galaxy SII, ie GT I9100, on T-Mobile, don't even bother yourself as you will be stucked on EDGE.
