Cant get 3G only symbol is E

I bought my HTC Diamond on UK. I updated the ROM to the RUU_Diamond_HTC_HK_WWE_1.93.831.1 this was supposed to make my phone QuadBand. It does work in USA (Boston) where I live. But I have never seen my phone doing 3G and speed test top was around the 1xx kbps.
Any Ideas?
PS. I am on the ATT network

Are you sure you have 3G coverage in Boston? Do you have a USIM-card (which I was told to be required for UMTS stuff)?

3G speed
I did look at the ATT coverage map and it said that I do have coverage.
How do I know what type of SIM I have? The SIM does have the 3G logo on it.

Are you sure your phone has the bands?
Check the Band setting, Settings->Phone->Band,
in the dropdown box for "Select your GSM/UMTS band", my US 3G ATT phone shows the following options:
Auto
UMTS(850+1900)+GSM(850+1900)
(oddly enough, the settings have to be on Auto for the phone to work..)
When I bought my diamond, I was curious about my sim too, so I took it into the ATT store and asked if it was the "latest 3G sim" and he said yes. Mine is half white (top) & half Blue (bottom), with a orange 3G fireball in the topright corner.
If yours matches all that, then take it to the ATT store and see if you get 3G in the store
Also..if you have doubts, I've had multiple Sales reps in the store tell me I can get a new Sim for free at any time, just need to ask.

3G
I do have that SIM half blue half white with the 3G fireball logo.
On my select network I have
Auto
GSM
WCDMA
on the GSM/UMTS band I have
Auto
UMTS(900+2100)+GSM(900+1800)
UMTS(850+1900)+GSM(850+1900)
UMTS(800+2100)
UMTS(850+2100)+GSM(900+1800)
UMTS(850)+GSM(900+1800)
UMTS(1700)

What ROM do you have?

RUU_Diamond_HTC_Europe_1.93.401.2
RUU_Diamond_HTC_Europe_1.93.401.2
Does this ROM supports USA 3G????

Sorry for my English
You have the European version and have only HSDPA 2100 / 900 (3G) and probably ATT works in HSDPA 850 / 1900, if this is the problem, sorry 3G is impossible for you, because is a hard problem, not a soft problem, search in this web there are many post about this. The European is quad band in GSM but not in HSDPA (3G)
CArlos

How about if I use another ROM
If I use another ROM ? would I be able to do 3G?

No I think it's impossible since it's different hardware I believe.

I think the one you have from UK, it only contained HSPA 2100 and US /Canada is using HSPA 850/1900, that's why you don't have the 3G signal.
Quad band only for voice and EDGE.

[Q] huawei ideos t-mobile 3g does not work

Hi,
I have a huawei ideos (older non X6 version) and supposedly it is unlocked. It works with 2g/edge. It does not work with 3g. I have looked for APN information and the info downloaded to the phone when I connected to network is identical to what is listed on the net.
tmobile docs url not allowed
i had to add the MMSC setting since it was not there as listed in step 12.
Things which are odd. When choosing access network, it does not say T-mobile 3G. It only says T-mobile 2g, Att 2g and Att 3g. According to the net this phone supports the frequencies for tmobile.
gsm link for u8150 not allowed.
shows HSDPA 900 / 2100 / AWS
HSDPA 850 / 1900 / 2100 / 1700
And
wikipedia entry for tmobile not allowed
shows
1700 MHz/2100 MHz UMTS (W-CDMA)/HSPA 4G (formerly 3G[31]) 2006 2008 (3G), 2010 (Marketed as 4G) First carrier in the U.S. to deploy services on AWS frequencies. Markets HSPA+ as "4G". UMTS band IV
Not sure if HSPDA spec is same as HSPA though.
I did the trick where you enter #*#*4636*#*#* and checked phone settings. I changed to GSM auto (PRL). I also tried to hit menu and select radio band, but it pulls up an empty "Set GSM/UMTS Band" dialog. There is nothing to select.
I guess my question is, does this phone support 3G for t-mobile and if so, what setting am I missing?
thanks in advance.
John

Wrong phone forum this is likely to get frozen.

hi

u have a better chance of getting ur answer their
goodluck

thanks
Thanks, I moved the question to general forum.

[Q] No 3G, just Edge, why?

Got an used Captivate on eBay, came with kernel 2.6.35.13 Glitch v13.1, MIUI 2.2.17, Android 2.3.7 and modem UGJK4
Well, Captivate radio specs for 3G: HSDPA 850 / 1900 / 2100
My operator (TIM) uses 2100 in my city, excellent until now!
But, I'm stuck in EDGE, can't get it to connect any faster. We have other phones here got from England, Ireland and USA, all of them support 2100 and 3G works perfectly, but not this Captivate.
Already tried the following modems: UGKG3, XXJTV, XXJVU and currently on UGJL2.
Just after installing the UGJL2, it connected at HSDPA, but after 5 seconds changed to Edge and no (H) anymore
A weird thing, I tried another operator chip (VIVO), that also operates at 2100 in my area and HSDPA is enabled normally!
Got back my chip and back to EDGE, this same chip get 3G+ (HSDPA) on a Samsung Jet, Samsung Galaxy Mini and a Samsung i550.
Everything else works perfectly, calls, GPS, wifi...
Any tips?
Thanks!

From what I know, the Captivate only gets 3G on AT&T even when unlocked. I might be wrong, but I remember reading that somewhere.

Must be a myth, I use my captivate on 850mhz in Australia 3g and hspa work perfect.
Did you try to force 2100 with service mode?
Phoned in.....

But with the other operator chip 3G works normally, at the same place where my chip also get 3G on other phone. Both are 3G+ (Hsdpa) able, but not when together. That is what makes no sense.
I would have forced in servide mode, but all the codes for service mode does not seem to work, and I've seen around the forums that MIUI don't have it...
Is there any code besides *#0011# and *#*#197328640#*#* ?
Both not work here
Thanks for the help!

MIUI and AOSP do not allow for the forcing of certain bands. You can specify what region you are in, but that's about all. To do that, use dialer code
*#*#4636#*#*
Phone setting
Menu/select service bands
That's about as good as it gets.
Hope it helps.

Your carrier uses the same 3g bands that att does. Those are the only ones that use the same 3g bands

Yes, I've tried Automatic and Euro (same bands used here), still Edge.
The strange thing is it get 3G from the other operator, that uses the same 2100 frequency... (at leaset they say it's both 2100)
Any way to see the frequency currently in use?

My carrier uses 850 and 2100.
My wife has a captivate also, her carrier uses 900 and 2100. Of course only the 2100 works but it is solid.
Phoned in.....

Ok, I discovered that it's an area problem probably, I tried at the office and got the H on the indicator! HSPDA is working, sometimes 'came down' to 3G (concrete building, not so good signal).
That's still strange because my friend get Hspa here, with a Galaxy S (I9000b), same operator, will call them soon to ask about this.
Anyway, it works! with ridiculous speed (180kbps), but it's better then Edge at 15kbps...
Thanks everybody for the help!

can't receive calls on mi5 while using 4g and phone screen locked (global rom)

i flashed my phone with the global rom and now when i lock the screen while using LTE Network i can't recieve phone calls
only text message arrives on locked screen
when the screen is not locked or when the phone plugged in charger every thing works fine
P.S. on 3g network i don't have this problem​

I bought new mi5 and faced similar problem and ordered a replacement.
But the same problem persists in the new handset.
So after going through a lot of search
I conculded:
The phone network does not support voice over LTE yet in some networks.
Currently it is supported in europe and japan and some networks of states.
So no need to panic xiaomi is getting a patch to update to fix this bug from their side.
Till time enjoy callin/ internet via 3g network
By pressing *#*#4636#*#*
Select network to wcdma by which u wont have any problem of incoming calls and no net issues!
If u dnt bother incoming calls ..u knw how to get 4g?

Well you're doing better than me my phones never displayed 4g in areas I used to have it with my lg g5 any ideas using the *#*#4636#*#* apparently lte is enabled I'm on Vodafone UK also allegedly supported

Mi3 not registering onto 3g after changing the motherboard

Hello.
I changed my motherboard recently to a MB I bought from AliExpress. MB is a WCDMA version. It works fine, but it does not register onto 3g networks. The same sim works in 3g in my other phone. When I search networks manually it shows awailable 3g networks. But when I select one it fails to register into a network. Please can someone help me with solving this issue.
Thank you
The model number says mi3w. Are there different varients of mi3w which doesn't support wcdma bands outside China?

My model says WCDMA. Are there different versions of WCDMA which do not work outside China?
