[Q] Will the Optimus 7 work with T-Mobile 3G? - Optimus 7 General

I'm *very* interested in the Optimus 7 -- and I never thought I'd say that about an LG phone!
Anyhow, one deal breaker for me would be 3G network access with T-Mobile. Anyone know if the Optimus 7 can do 3G on T-Mo, or is it only Edge network speed? I see that the Optimus 7 covers several frequencies, but I'm seeing conflicting info as to what is the 3G band for T-Mo. I've seen 1700mhz and 2100mhz listed for T-Mo's 3G. The Optimus 7 appears to cover the 2100mhz range, but not 1700mhz.
So... does anyone know if it'll work? Anyone have first-hand knowledge?!
Thanks,
Yip

This is a great question. Unfortunately, I have no concrete answer for it. However, I came across a very interesting piece of information in the MFG software on the LG Optimus 7 I have ( from Telus ). There does not seem to be any 1700 band support, but there is an unexpected 900 band support for 3G. ( Optimus 7 owners should check the Call UI Display in the MFG menu, or go to the Engineer Menu and check modem settings->band settings ). I guess since this device is being launched in Europe, LG used the same quad-band GSM/quad-band 3G modem in the Optimus 7, but the 900 band is disabled by default in Canada.

Unfortunately, LG Optimus 7 does not support AWS, hence it will not support 3G neither on T-Mobile USA nor Wind Mobile or Mobilicity (it will fall back to GSM/EDGE modes on T-Mobile and will always be in Wind Away zone roaming through Rogers if you were to use Wind Mobile SIM card).
I have the opposite question - do you know if T-Mobiles HTC HD7 will work on HSPA+ networks like AT&T, Telus or Rogers? Or it only has AWS 3G?

3G international compatibility

Hi there guys! Now that the phones are finally shipping, can anyone please test the real band compatibility? I want to buy an unlocked G2 and use it here in Italy, but only if I can get at least a fully working 3G connection.
Please fellas, I badly need this info..
Thanks

No such luck chief. The only 3G band on the G2 is AWS. It will only work on carriers like T-Mobile (USA), and Wind (Canada).
The stock Desire Z, however, has HSDPA 900 / 2100 and should work in most non-US countries on 3G, but check your carriers bands first. The downside, Desire Z has 1.5 GB storage, the G2 has 4 GB.

Unfortunately I think you are going to be disappointed. I posted a buzz about this a while back. You can look at page 3 of the test report in the FCC submission. The nutshell summary is that the device will only support Band IV for 3G, or in other words T-Mo US' UMTS 1700. This is unfortunate since I used my unlocked G1 quite a lot overseas, thanks to its UMTS 900/2100.
You'll probably have to go with a Desire Z if you want this device with European radios.
Can't believe it's for real...I mean, the 2-year-old G1 does that...and what about people working overseas?
That's a MAJOR fault from T-Mobile, and it's totally weird to say the least.

Perhaps tmo figures that frequent int'l travelers are a small enough percentage of their userbase that omitting the Band I poweramp was worth the cost savings?
Oh, it gets better. I only paid attention to the UMTS bands when I read the report, assuming that any modern smartphone would be a quad-band GSM device. Turns out the G2 is only GSM 850/1900, which means this device is truly unusable in Europe and Asia.
Wait a minute, what GSM bands are used in Asia?
The HTC site says otherwise : http://www.htc.com/us/products/t-mobile-g2#tech-specs
According to T-Mobile and HTC sites specs, the phone is GSM quad band (850, 900, 1800, 1900).
The HTC site says "UMTS: Yes"

Europe and Asia are GSM 900/1800, generally. What is interesting is that the HTC page claims the G2 is quadband, but the FCC testing documents don't show any 900/1800 data at all. The phone cannot legally operate in the U.S. in that band unless testing data has been submitted to the FCC. I'm wondering if HTC marketing just c&p from the Desire Z specs and forgot to edit the GSM infos. We'll see soon enough I suppose.
it doesn't make sense why they would release a phone that wasnt quad band. it must be a mistake. it is like power seats on a luxury car. it's just there lol.
So a unlocked G2 could be used on WINDs network here in Canada (because they use the same frequency), can some one confirm this please

Wind uses AWS (UMTS Band IV)... So, yes. But if they do not have HSPA+ enhancements you won't get the famed and promised super speed. The phone should be able to be used on USA (T-Mobile, Cincinnati Bell Wireless), Canada (WIND Mobile, Mobilicity, Videotron)
Based on the G1 test reports...
... the bands listed in the FCC test reports are not at all definitive.
I pulled the FCC exhibits for the G1 and they listed:
GSM 850
GSM 1900
WCDMA Band IV
(plus 802.11 etc)
In other words, no Band I.
However, I've been successfully using my G1 on 3G in both Europe and Asia for over a year now, so it actually has Band I.
I suspect the FCC tests only cover the frequencies that the device is going to be used on *in the US*. Frequencies the device may or may not be capable of using outside the US just aren't relevant.
That being said, the more significant detail is that the T-mobile site lists the G2 as only having Band IV, even though it lists the Vibrant as having Bands I and IV. Looking at other phones, it seems that T-mobile isn't terribly consistent in how they list their frequencies, but that's a (relatively) slim thread to hang onto.

It is quad-band -- for GSM -- as all (most?) modern non-CDMA phones (and some of those) are. But the OP question is about 3G.

I wouldn't put it past T-mo to have just messed up the detail.
I suppose the easiest way to determine would be for someone with an unlocked G2 (or even a locked unit) to take it to Europe or Asia and see if the system status shows UMTS signal or not.
Unlocked G2 Australian user
Hey Guys,
I actually received my G2 a few days ago. Yesterday i purchased an unlock code and entered this in to the phone which it advised was accepted.
The device then rebooted, however once the system loaded i noticed my signal bar had an "x" through it.
Browsed to Network Operators and tried selecting to search for networks and also to select automatically. Both of these selections returned an error "error searching for network" or every second try it would say "unable to connect to network".
I tried a factory reset of my phone but still the same issue.
I tried dialing *#*#4636#*#* which opens a testing screen. I noticed on this screen i can see i have a signal of -85 dBm which is similar to on my galaxy s.
Tried playing with the settings on this screen, i had the option to select network band to which i alternated between all options including auto and AUS, AUS2.
I can confirm this is a Vodafone simcard and it works perfectly in other phones.
I tried a Telstra, 3 and a friends Vodafone simacard all of which produced the same error.
I noticed there are several Australian sites selling unlocked Tmobile G2's.
At this point i would like to try flashing the stock rom on again however i am not sure on the button combo to access the recovery screen.
Last thing to note is yes i have spoke with Vodafone, HTC AU and HTC US, none of the techs were able to help me. =(

Would a G2 work on Softbank (Japanese Carrier) They use the 2100 band IV I believe. I know my T-Mobile Nexus One worked fine on there 3G.
I could care less if the HSPA+ worked just 3G would be fine.

Band IV is commonly referred to as AWS 1700. From the gsmworld entry, it looks like Softbank is running on Band I ("UMTS 2100"). The G1 and Nexus One both had UMTS 900 & UMTS 2100 (the global bands) in addition to T-Mo specific AWS 1700. We're trying to determine if the G2 also has 900&2100 radios, but right now it's not looking very good.

[Q] htc surround not 3g with t-mobile

I have am htc surround unlocked from at&t and using it currently with t-mobile everything works fine however the 3g is not working is there any configuration for the apn our something that I need to do to make it work please somebody help me.....
No. The hardware is different.
T mobile and at&t use different frequency for 3g data.
Unfortunately surround only support at&t frequency so u can't use 3g on t mobile network.
if i not mistaken the htc surround supports lte 4g.... so you might be able to
im not sure you might have to wait for a update

Not true. The Surround does NOT support 4G LTE.
In reply to the OP, the Surround isn't getting 3G on T-Mobile because it only supports AT&T's 3G bands. Carriers do that so you cannot use the phone elsewhere if you try to weasel out of your contract. If you bought it off-contract, you should have stuck with AT&T because there is no configuration or any setting that exists that will get the Surround to use T-Mobile's 3G.
If you need 3G, you should probably consider returning the phone if you still have the chance and go get the HD7 instead.
Hardware
The Data bands used for AT&T are different yes, but this phone is a data quad band phone, so the antenna should be able to pick up the signal for T-Mobile or AT&T. It should be no more than a configuration issue. Both the HD 7 for T-Mobile and the Surround for AT&T have the same radio for data reception (/us/products/compare/120-121?view=1-1&sort=0&filters=0-11-0). Add www and htc and dotcom to the link.
Nope.
ATT offers UMTS or 3G using 850mhz(the old TDMA band) and 1900mhz.
While T-mobile offers HSDPA (technically 3.5g part of the UMTS specification) using 1700MHz for uplink and 2100MHz downlink.
The Surround would have to be 850/1700/1900/2100 3G and 850/1900 GSM (voice) to work on T-Mo's 3G.

Any way to unlock/flash 1700 band in LG e900

I am living within US using Tmobile on my LG Optimus 7 e900. My understanding is tmobile only uses Band IV (1700/2100) within the US - but this phone does not have the 1700 frequiency option.
Do you know if the frequency is availble in the hardward (just not displayed)?
Do you know if there is a way to flash the ROM or enable within the registry?
Not sure I can live with roaming EDGE speed - any help is much appreciated.
It's not an unlock band issue -- this phone simply does not support the T-Mobile 3G bands.
Best bet? Wait until T-Mo and AT&T merge... 'cause this phone *CAN* use the 3G bands on AT&T
Both the LG Optimus 7 E900 and E900h support quad 3G bands 850, 900, 1900, 2100. The modem on-board, as well as the antenna configuration simply does not support the AWS 1700 band that T-Mobile uses. So, unfortunately, until the merger goes through, you will be stuck with 2G/EDGE...

[Q] Terrible speed on T Mobile

Hey guys, I picked up this phone to test out a winphone a while ago and like it, but I'm having a huge issue.
I cannot get any network other than Edge to show up, and my speedtests are incredibly slow! On my Galaxy Nexus on Tmo's network I had to have the IMEI number updated somehow when I started my account, but it appears Tmo is closed today. Is there a way of doing this, or something else I need to do to get my Quantum to speed up, or is it hopeless?
It originally was an ATT phone that I unlocked to run on Tmo.

That's because AT&T and T-Mobile use different bands. AT&T phones are only compatible with T-Mobile 2G. If you're lucky, T-Mobile will be refarming spectrum in your area, so you can get 3G, but apparently this isn't the case for you.
Source: I have a Quantum on T-Mobile
Are you positive about that? I have a Galaxy Nexus that worked just fine once they updated the IMEI number, and now I have full use of Tmo's network on it. It was an ATT phone initially...

2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1700 / 1900 / 2100

UMTS/HSDPA Tri-band (850/1900/2100 MHz)
T-Mobile:
850 MHz/1900 MHz GSM/GPRS/EDGE/UMTS/HSPA 2G

1700 MHz UMTS/HSPA/HSPA+ 3G/4G
1900 MHz UMTS/HSPA/HSPA+ 3G/4G
1700 MHz LTE
The Quantum supports the italicized bands.
The Nexus supports the bolded bands.
As you can see, the Quantum's supported bands are used for 2G.
That is unfortunate... so everyone else using this phone is using it on ATT's network, not Tmo's?
Also incredibly disappointing since I was told that the networks were the same and that a phone that worked properly on one would work on another...

Yes, most users are on AT&T. And as to your second point, I've never heard anybody say that...
I'll go ahead and bump this with one more question. With the announced merger between MetroPCS and T Mobile, is it safe to assume that MetroPCS' frequency spectrum will work with T Mobile phones? I believe I saw at least one band that the Quantum would be able to use.
I get Tmobile 3g on my Quantum, I'm in an area where they have 1900MHz coverage though.

AT&T LG G2on Tmobile...no signal! HELP!

Just bought an AT&T Lg G2 and unlocked it for Tmobile/Metropcs use and after setting APN settings I still have no connection at all. Im unable to send a single text, get online or anything. Im sure im doing something simple wrong. Tmobile has 4G in my area so i should get great speeds. Anyone got any ideas?
I've entered APN for both 4G and non 4G
Did you reboot? Probably did but it already, right?
yup I've rebooted multiple times. Went into Networks searched networks it found AT&T Tmobile and MetroPCS and a few others. i've tried AT&T tmobile and Tmobile LTE and Metro PCs...all with no luck

I'm afraid that the AT&T D800 does not support AWS/UMTS Bands, which are T-Mobile's main frequencies. I've just pulled this list from Wikipedia:
AT&T - D800
GSM 850/900/1800/1900
UMTS 850/1900/2100
LTE 1900(2)/1700(4)/850(5)/700(17)
T-Mobile - D801
GSM 850/900/1800/1900
UMTS 850/1700/1900/2100
LTE 1900(2)/1700(4)/700(17)
Namely, you are missing UMTS band 1700 which manages about 50% of T-Mobile customers' HSPA+ connection. That being said, the fact that you cannot connect to T-Mobile's LTE band 1700 is weird. Also, UMTS band 1900 should also work.
Perhaps you're in an area with ONLY UMTS 1700 which would not work with the AT&T LG G2. Do you know if there's LTE coverage in your area?

Yes I am in DFW area which is one of the largest LTE areas Tmobile has. I'm unable to get a connection at all. It says phone is for "emergencies only" I cant make calls, text, or use web.
Sounds like the phone is not SIM unlocked. Need to verify it is SIM unlocked. Also where did you buy it. If the phone was bought from a person it could have been reported stolen or lost and blocked from T-Mobile.

I bought it off Swappa. Ill try the unlock code again but it said it was unlocked. it doesnt come up with any error when i put the new sim card in anymore.
You're likely in an area that does not have HSPA 1900 coverage; and since you're AT&T variant doesn't support the band, is showing no service. Locking onto LTE wouldn't help as HSPA is required for voice access.
I created a thread in the Q&A asking for ways to enable the missing AWS band on our AT&T / Canadian variant handsets. It was doable on Samsung and am hoping it can be done on our handsets.
turns out MetroPCS had to activate it. you cant just stick a sim into a new phone. they have to activate it on your account. $15 later (yeah i know...its BS) but the Lg G2 is up and running and getting 4G speeds
