[Q]Optimus 2X on AT&T UMTS 1900

I was wondering if anyone has tried popping in an AT&T SIM in an Optimus 2X to see if UMTS 1900 MHz works. I know it's been done on Anandtech on a P990 model... but it would nice to be sure that Anand and friends didn't get some special LG surprise model.
I'd link you guys to the Anand article but I'm new here and XDA doesn't want me to post any links until 8 posts. =(

It works. I use it on at&t's 3g.

I did a research in LG websites,
The only countries that mention that the P990 have the UMTS 1900 band are:
-Poland
-Slovakia
-Spain
-Holland
-Czech Republic
-Belgium
-Australia
-Hong Kong
-Taiwan
Other countries LG websites does not mention the 1900 band, all mention 900/2100. And some like the UK shows the 1700 Band too.
Notice that all sites show the Device as Model: LG P990.
So now the question is does the LG P990 have the UMTS bands 900/1700/1900/2100? since all are the same model number, or is possible that all have different UMTS bands chips?

Agh double post

Got from an eBay seller in Singapore.
The box on the phone states 900/1900/2100 UMTS so i am not sure why some LG local websites only state 900/2100. i am pretty sure they are all the same model.
If you want to the info on the eBay seller, PM me as i don't want people to think i am spamming

When the G2x is a hopeless case for me and retailers for the O2X cannot guarantee UMTS 1900 MHz support, I'll contact you on that seller. Thanks for the offer!

Thanks clubtech for the info. Do you know if AT&T detect it as a smartphone since I am on their $15 media net plan with my current phone?
Can you pm me the seller as well? thx

Is the phone unlocked? If I grab one from TMobile will it work?

It is unlocked. It is not the same as the TMobile G2x (In terms of hardware, the cell modem & GPS are different.)

I think Tmobile G2xworks on wind/mobilicity
The Optimus 2x (O2x) does not work with wind/mobilicty according to this:
(Voice yes/data no)
LG P990 Optimus 2X
2G Network: GSM 850 / 900 / 1800 / 1900
3G Network: HSDPA 900 / 1900/ 2100
As for the difference, I assume only the brand logo on the screen or maybe some Tmobile apps.
-----------------------------------------------------------
I m too looking to waiting to get this into Canada.
However I'm worry about the freeze and otherse problem with this phone.
I'm holding it out until they have a *offical* fix and confirm it is not a hardware problem.
I have all the time untill SGS2 drops to around the price of this phone =)!
Plus it seems like the Motorola Atrix have reboot issue too..
My guess is a problem with the tegra 2 problem with software.. who knows...
*Edit* notice you're from Vancouver, how is mobilicity/wind service there?
Heard reception are crap =/

Mobilicity is awesome but wind service is crap. 10$ for unlimited data and mobilicity towers are built and maintain by Ericsson. Call quality is very good and clear. Even mobilesyrup.com said it. Ya also wanted sgs2 but no 1700 and 2100 band. I don't believe the random shutdown problem till I buy the phone.

[Q] Wind Mobile - Can it run on the big 3

Wondering if the Wind mobile unit is tri-band aka TMo or quad, meaning a true GSM world phone.
Sent from my Desire HD using XDA App

No, generally the phones are not interchangeable as they run on different frequencies. So unfortunately you still have to pay outrageous prices for the big 3 phones

according to the website it is
http://shop.windmobile.ca/ProductCa...ls.aspx?id=LG+Optimus+2X(WINDCA)&color=orange
As long as the phone is unlocked and the frequency is within what was listed, it should be usable.

It will only work on rogers, fido, wind and mobilicity you need HSPA 850 and 1900 to work on bell or telus. I don't think there are to many if any phones that will work on Wind and also Bell or Telus.
Videotron should work to.
I'm no expert on phones but I was looking into this to and that what I found here is a link to where i found it.

So it's HDPA on roger's. I'll look into wind's return policy.

No, the Wind "Optimus 2X" P999 (known in the USA as G2X - this is NOT the same as the Optimus 2X P990) will only get EDGE on Rogers, not HSPA.
Something that needs to be hammered home over and over... Quad-band GSM doesn't matter anymore. Just about everything is quad-band GSM nowadays. The spec you should be caring about is the 3G/UMTS bands.

LG P925 (or P920) with 4G or 3G for T-mobile USA network?

So, I'm using a P925 thrill AT&T branded which is UNLOCKED on T-mobile USA. But only getting 2G edge data speeds, and I'm being told no matter what I do, or what baseband I flash, I will never get anything other than edge on this device. My question is, is there a comparable device that DOES offer 3g/4g T-mobile USA compatibility?
I'm trying to migrate from unlocked iPhone's (again, using on T-mobile USA) to Android - simply because I'm bored of iPhone's... Have had them all except the 4S - but have a iPhone 4 so its pretty much the same thing. While I know the 3D of the Thrill is a little gimmicky, I think its one of the coolest "gimmicks" to hit in a long time, and because I only recently got a 3D TV -- well, recording 3D video's and watching them at home is pretty effin cool.
So, am I stuck with a T-mobile branded Galaxy device if I want 4G or 3G on T-mobile USA?
Any advice would be helpful, since I'm pretty much an Android Noob! THANKS!

If I remember correctly the optimus 3d might work with t-mobile usa. But you might have to double check just to make sure .

This is off topic, but how did you unlock your phone?

You should be able to use the 2100 UMTS band with T-Mobile, but I believe you need both the 1700 and 2100 bands for full 3G. If so, you need a baseband for either T-Mobile, Wind or another Canadian Carrier with T-Mo's 3G bands. The nice thing about this phone is it's flexibility of use with other networks by baseband flash. (Now we need other leaked GB basebands.... Ugh.)

If you want a non branded Android phone that works on Tmobile 3G/4G bands look at the Incredible S, Sensation (International Version), Sensation XE, Nexus Galaxy, the TELUS version of the Galaxy S II and the Nexus S.

i also want to know

yes o3d p920 works. but there are 2 versions of p920. make sure it has 1700mhz baseband. this is where i bought
http://www.atgsm.com/LG_P920_Optimus_3D_Black_p/phone-lgp920black.htm

So are there any basebands available that I can flash to my p925 to get t-mobile usa 3g/4g speed?

Q: how did I unlock my p925?
I took it to a store, and they unlocked it for me.

If I try to use a baseband for T-Mobile USA on my Thrill would that screw up my phone? If there is any posted can someone post the link here ? I tried to look for it and couldnt find it.

Where did you get your thrill unlocked

I am also looking for this baseband so I can get my LG Thrill 4G to work with 3G (or hopefully 4G) speeds on T-Mobile. Please share the love!
I'm only getting 2G speeds on T-Mobile (I am in the USA, San Francisco area).

UPDATED: My buddy gets 4G on his stock LG 3D FROYO but I get EDGE. Why?

UPDATE: please ream my post from March 13. Thanks !!!
Hi!
Today at the table in lunch room I noticed that buddy next to me had 3G connection on his iPhone. But I had only EDGE. So the obvious question is WHY? Should I play around with baseband+RIL? Any other suggestions?
Thanks in advance!

Are you both with the same telecom provider?

Thanks guys!
I know I'm a lammer, but not the total lammer
Yes, we are on the same network. Yes, I have 2G/3G enabled - at home I get 3G/H.
Any other ideas?
Thanks in advance!

Your phone doesnt support the network frequency. Optimus 2x does 900 and 2100mhz 3g. If your provider uses 850/1900 for example its not going to work is it?

Thanks for reply!
Do you think iPhone has more frequences than 2x?
As I said in OP, at home (50 km from work where my buddy gets 3G and I don't) I get 3G and H. So my phone is capable. As far I tested 725 and 218 BB+RIL. Tomorrow will try 823 (can't flash BB at work).
Thanks anyway!
Sent from my Optimus 2X using XDA App

iPhone 4 3G supports: 3G Network HSDPA 850 / 900 / 1900 / 2100
2x: 3G Network HSDPA 900 / 1900 / 2100
So yes we're missing the 850mhz band, which is unfortunate because the best provider in Australia uses 850mhz 3G, I only get 2G EDGE when I put a Telstra sim in my phone.

Ok, quest continues...
I tested 823 bb - same thing...
Yesterday my another buddy got used LG P925 (3D) and asked me to root it. So I did.
And when I tested his his phone with my sim at the same spot - I had 4G symbol and Speedtest showed ping around 150 and download speed around 2000 kbs. My LG P990 is on Edge and has ping close to 1000 speeds around 200... WTF?
Here the only difference :
my phone is from UK and his is specifically Canadian (we are in Canada ).
But I checked LG UK site and it says that phone has 850-900-1800-1900 bands, exactly as my buddies.
My buddies P925 says UMTS network, while mine only HSPA... Does it makr a difference?
I really like my phone but being on Edge kills me... I guess I will return this phone and try to find used Canadian one...
Any ideas?
ADDED: I read and read and read and finally read about European phones not having 850 frequency enabled... I guess this is my case - my phone is from Europe and buddies - Canadian. So I found how to get to hidden menu on stock ROM and modify preffered frequencies. But is there any way to get there in CM7? Ideas ???
ADDED 2: ok, looks like European o2x doesn't have WCDMA850 enabled... Here my experiment:
http://forum.xda-developers.com/showpost.php?p=23588400&postcount=16
Is there any way to enable WCDMA850 band through some menu? (I've read that Samsung has such feature)

Thread can be closed...
Hi everybody!
I think thread should be closed - I find the answer.
This European phone doesn't support WCDMA850, only 900, 1900 and 2100. So in my case in the little Ontario town I didn't have 3G connection because Rogers (provides) has only CDMA850 band for 3G...
Only big cities have 3G in WCDMA1900 band...
Just all of you know.
With best regards!
