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] change modem or unlock needed for traveling with a Tmo tab w overcome?

Hello experts,
Would you please tell me if I need a new modem (currently on T849UVJJB, assuming that's stock modem), or do I just need to carrier unlock my tmobile branded galaxy tab in order for me use pre-paid sim from other countries such as Hong Kong or Taiwan.
I have already rooted my galaxy tab and installed Overcome 3.0.0 on it. I am interested in voice + data, but all these different radios and talks of voice calling is disabled on the tmobile server's side (thus only network unlock is required to get voice +data) had me confused.
Greatly appreciate it if someone can clear it up, thanks.

To use any sim besides t-mobile, you need to unlock.
You will need to root your tab, then unlock it.
Since there is no compatable network in China the best you can get is voice and EDGE data.
Use a froyo modem.

Thanks rangercaptain for your reply.
As I mentioned I have overcome rom installed, thus I am already rooted. I also installed from the market galaxy_s_unlock, and it seems to be working (although I won't be able to find out until later when I travel.)
you mentioned it will only do EDGE, which I am dumbfounded:
-most Asia (including China) and Europe support UMTS 2100, known as Band I
-Tmobile galaxy tab spec page listed it supported both UMTS 2100 (Band I) and UMTS 1700 (AWS)
I am traveling soon so I guess I will report back. But if there is any actual report from users that would say one way or the other it would be awesome.
Thanks.

The word "and" is the key. The t-mobile tab has to have 1700 and 2100 bands to have 3g/H. Outside of US t-mobile service area, the 2100 band is available, but no 1700 band.
Go prepared for EDGE and be pleasantly surprised if you get 3g. It has worked out in a few places.

well, I am at Hong Kong right now, and here's what I found:
I am using hutchison 3G, JPE modem.
Yes I get voice. Data: GPRS works, EDGE works (though most of the time is G)
But whenever the icon indicate 3G (even with 4 bar) I get no data, at all.
Here the head scratcher: When 3G swtich over to the letter H, if it is above 3 bar I can get data! But I thought 3G and HSPA is on the same frequnecy and if it works for H it should work for 3G also.

That's because the bands for 2100 match, and the US 1700 band and the overseas 1900 band have a small overlap, so you occasionally hit the sweet spot.

[Q] Unbranded unlocked Milestone cannot connect to data service on AT&T or T-Mobile

[Q] Unbranded unlocked Milestone cannot connect to data service on AT&T or T-Mobile
I bought a M1 off Amazon about 5 months ago. I don't have a data plan in my home country as my SIM is company provided without data. I get by with wifi most of the time. Over Christmas while in Miami, I tried my nephew's T-Mobile SIM from his HTC and I tried an AT&T SIM with $5 data - and neither would connect to EDGE or 3G. The phone could still make calls though. Anyone have any idea why that would be? I have no clue as to what region the phone would belong to -so I do not know what GSM frequencies it operates on. Motorola's website specs says that the GSM version operates on 850/900/1800/1900 MHz - and supposedly AT&T 3G operates on 850 7 1900 MHz -so I can't figure it out. Could it be something software/firmware related?

It's a APN issue if you can make calls but cannot connect to mobile data. Check your provider's APN configuration. (Just google it.)

yeah. check your apn. for stock rom and some other mods apns cant be configured automaticly

[Q] Stuck on Edge after 4.4.2 update

Hello I just received a brand new S4 active (GT-I9295) after my old one had some watter resistant issues
In the old one I had flashed the 4.4.2 from netherlands (I'm in Portugal) without any issues. So 3G (HSPA+) and 4G working perfectly in Portugal at optimus (P OPTIMUS uses the GSM 900 / GSM 1800 / UMTS 2100 frequency bands for its network.) Then it took a swim and I've ended with a new phone.
Now this one came with 4.2.2 TPH version. The guys at samsung had to change it's imei, and when it came to me not even boot recovery was working (error no command). Now I've flashed once again the 4.4.2 from Netherlands and Germany I9295XXUCNE5 base band with Kernel 3.4.0-1429916 and compilation KOT49H.I9295XXUCNE5.
The problem is. With this new phone and with the same simcard I've previously used and its working in 3g and 4g in other phones I'm stuck at EDGE with (LTE/WCDMA/GSM auto option) and if I select WCDMA only I get no network at all.
Also besides this there are a few wi-fi networks where I'm no longer able to connect (getting ip address forever) but the pressing issue is really 3g /4g connectivity.
Will I have to wait to a TPH (portuguese) rom? With the other phone all of this was pretty straight forward. The reason why I need 4.4.2 in this phone is my gear. But I don't want to give up 3g/4g and since this was working with the same settings there should be some workaround.
Thank you for your help

4G Network NOT accessible on MI5 PRO 128GB

I am in a country where all Network Operator uses Band3 (1800Mhz) for LTE. And i have search everywhere and it is clearly mentioned that mi5 pro do support lte Band3 and yet i can seem to be able to connect at all!
I am using China Stable version 7.5.6 and yet just cant connect at all to the LTE Network even when i manually tries to search and register to 4G Network, it just goes to No service then Emergency Calls only. :crying:
Hope anyone can help me out with this as i find it very sad that i cant use 4G in my country.
I have already tried several times to change stuff on the *#*#4636#*#* menu but still it just does the same thing. i have sims of all 3 operators and yet none of them connects to the 4G networks.

Maybe add the APN and turn on data for the sim you're using?

It should certainly work as I'm with Three who operate on 800 and 1800 and 800 isn't supported but I still receive 4G signal. As mentioned try manually adding the APN for your network?

I don't have the 'prefer LTE' option under mobile network but still can connect to LTE network in my country (1800Mhz), this happens for both china stable 7.5.6.0 and global stable 7.5.2.0 ROM

Can you update to lastest Xiaomi.eu version (Miui 8) and check the 4G on that 1800band?
