Hii all
I'm from India, using Sony Ericsson Mini pro (u20i) and still in Airtel 2G and here Telecom Operators just started to roll out 3G services. Currently Airtel, Vodafone and TATA Docomo providing 3G services here.
I checked my handset compatibility both in Airtel and Vodafone websites. According to them my Mini Pro is 3G enabled but based on WCDMA technology so i get low speed 3G upto 384kbps. So they are suggesting me to upgrade HSPA enabled handsets that supports higher speed 3G that varies from 14mbps to 21mbps. I have been told that 3g on WCDMA really sucks as compared to HSPA enabled handsets.
According to Tata Docomo which provides HSPA + (also dubbed as 3.5G+) service and as they mentioning in their 3G handset compatibility list that Mini pro supports HSPA and it is a superior 3G ready handset. Sony Ericsson Indian website also states that it has Turbo 3G and HSPA enabled. Even in my handset box it has clearly mentioned that handset has HSPA and Turbo 3G.
Now in the handset settings menu, there is an option to select network mode which only gives only 3 options that is WCDMA only, GSM only and GSM/WCDMA.
So which one is true? Is my Mini Pro HSPA ready handset or only supports WCDMA? What Sony Ericsson and Tata Docomo states is true? or Airtel and Vodafone? Which Sim to buy? Im in great confusion. Please help in this regard.
it is HSPA ready. in spain, with vodafone i get the H icon of HSPA
Its hspa bro..im using mini pro nd while using mtnl hspa I got 3 mbps speed...our handset supports upto 7 mbps speed I think...

Yeah it IS HSPA enabled, it uses it by default usually, which adds to the miserable battery life if there is no 3g or HSPA signal available, as it continually scans, looking for it.
Mine actually uses HSPA by default, dropping to 3g when the signal is poor and down to G when it loses 3g altogether. (H, 3g, G respectivly).
Rooted phones can also have the full power of the connectivity chip unlocked to achieve up to 8mbps depending on provider and reception etc.

Quickly knowing your phone is via its signal which either H, E or G on top of the signal strength bars. Mine usually showing H.
I think they goes like this:
H - HSPA
E - Edge
G - 2G or GPRS
Thank u all for clearing my doubts. Got relief now. Really appreciated your help.
what about the mini?

Excuse me? What aside from 802.11n support (which has nothing to do with mobile provider) can be "unlocked" in a rooted phone?

LOL, Mini and Mini Pro hardware is identical in almost every way. In short, yes.

Hi everyone,
I apologize in advance for the possibly n00b question. I am in Italy now with a T-Mobile USA G2 that I unlocked with GFree 0.5/adb/everything yesterday. I put in my TIM (Telecom Italia) SIM card and it finds the TIM network and connects me to normal phone service, but simply does not connect to 3G. Does anyone have any ideas? I'm assuming the G2 is capable of overseas data connectivity because T-Mobile advertised it as a "quad-band" phone -- am I wrong? Do I need to install a custom ROM to have international 3G?
Yeah, I think you are screwed. According to the t-mobile site here your quad band phone has the following freq specs:
850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band IV (1700/2100)
The band IV is the t-mobile 3G band in the states that uses 1700Mhz uplink and 2100 downlink (also known as AWS). Unfortunately for you Italy uses the typical European freqs of 1900Mhz uplink and 2100 downlink. And no you can't just use the downlink!
On the bright side, EDGE should work.
Thank you very much. I think you are correct: it's shameful and pathetic that T-Mobile advertises the G2 as an "international" phone and then provides a phone with support only for a single UMTS data band (unlike the iPhone 4, for example, which has support for 900 MHz UMTS/HSDPA).
As per the suggestion that EDGE should work, that does not appear either. All that appears is the "cellular" network icon -- a.k.a., the one immediately to the right of the battery. There is no "E" data connection either as there would be in the U.S. when I am out of 3G range. Is that normal? Is EDGE simply the normal cellular network?
I feel your pain, having traveled internationally a lot
No, when you are connected to GPRS you should get a "G" symbol near the signal bars and when you are connected to EDGE there should be an "E." If you are not getting that then a couple of suggestions:
1) You have switched on the data connectivity on your phone, right!!? (duhh)
2) Did you buy this SIM card new? There are older SIM cards where I had a problem getting the data connectivity, though that should not be a real problem.
3) Did your phone get the right APN settings from the SIM? In most cases for TIM I think you want ibox.tim.it and you *might* have to set in manually
4) Is this a prepaid SIM and do you have a balance? The network will probably reject the connection if you have 0 balance
5) If you don't have a plan (even prepaid), your balance will go down VERY quickly. In fact, your phone may have actually connected when you were not looking, and run your balance to 0 just by syncing.
The best deal for TIM data packages are listed here. I use them all the time, however if you are in the big cities WIND is pretty good and MUCH cheaper.
Hope that helps
Hey guys. I just recently updated my Sony Ericsson Xperia X10 for use with T-Mobile 3G Data. I originally bought my X10 locked to AT&T but I had the phone software unlocked for like $50 bucks to use it with T-Mobile. Can anyone help me out? I popped my sim card in my brother's G2X and it connected to the T-Mobile 4G tower just fine but it won't connect to the 3G towers at all on my X10. Any help on this would be greatly appreciated.
Do a Google search for apn of tmobile.
Edit: also you have a phone that is on the wrong frequencies. Tmobile uses 1700, at&t Uses 850/something else.

I entered the proper APN settings and it's still not working. Since it was the AT&T Xperia X10, could that be the reason why it's not working registering on the T-Mobile 3G towers?
Go to Settings/Wireless & Networks/Mobile Networks/Preferred Network mode/Click GSM/WCDMA preferred.Then go to Network Operators/Wait to connect if not go to Search mode/Select Automatically/Search Networks. It should connect to three networks
(house icon) 3g an be Checked/(house icon) 2g DR/ (no icon) 2g that's your sms/mms.
Although you may only have two Networks (icons) with the primary one checked or you well be roaming. Also X10a an X10i have differences in bands so you may have to change your Firmware/Baseband/Rom.
Also you can check your friends Access Point Names and try that.
Settings/Wireless & Networks/Mobile Networks/Access Point Name/Menu/Add APN.
And put in the Exact settings/Menu/Save/Reboot Phone.
You may have to what a few to connect a minute or two.
I'm bummed out, no matter what I do, my phone simply won't connect to the T-Mobile 3G towers in my area. Since this was the AT&T Xperia X10, it doesn't support the same 3G bands as T-Mobile's. Could I be wrong? I've tried everything. I flashed the stock 2.1 rom on it and it still couldn't read. It kept registering me on T-Mobile 2G with E on the status bar. Are there actual Sony Ericsson Xperia X10s that support T-Mobile 3G US?
There are 3 different types of x10's;
the x10i, x10a, and that Japanese one (s0-01b?).
They all use different frequencies (can't recall them off the top of my head).
Afaik, AT&T uses x10a's because they work with the frequencies that at&t broadcast 3g on. T-Mobile uses x10i's because they work on the frequencies that T-Mobile broadcast 3g on. Because you got the x10 from at&t, its very likely that you have an x10a, which will not work with T-Mobile.
Flashing roms, kernels, basebands, whatever CAN NOT change this. The frequencies are set in the actual chip on the motherboard. The only way to change this is to buy an x10i unfortunately.

Hey guys,
For those living in the US... do you happen to know what companies are compatible with our 3G bandwidth frequencies ?
I bought a T-Mobile SIM Card, it's working fine but I can't get 3G (UMTS) , just 2G (GSM) since T-Mobile uses 1700 and 2100 Mhz for his High Speed Data connections... and this mobile (both, sk17a and sk17i) doesn't support 1700mhz, but 850, 1900 and 2100.
I know AT&T uses 850&2100Mhz for 3G, but I think this company banned internet calls through 3G, which sucks.
So... is there any other company compatible with our mobile with 3G support?
Thanks
Did you order the phone outside of the US?
No, I ordered it on amazon and is the American model
Sent from my SK17a using XDA App
I got mine on Amazon and it's a SK17i.
I have T-mobile, but I have a problem with losing network randomly every now and then whatever I do.
edit:Apparently it was a SK17a. Could've sworn it said SK17i on the order page... Odd. Oh well.
I have network mode on manual and set to GSM only, but I still lose signal sometimes...
Try setting 'network mode' to manual, and choosing 3G or 2G only. It seems to help.
Hi...
Mom bought for me a Htc Evo 3D Gsm at stmmiami last november i haven't
rooted my phone, it has all the ota updates, it's on Android 2.3.4, Sense 3.0,
software number 1.22.707.3, baseband version 10.55.9020.00U_10.13.9020.29_M .
I'm in Belo Horizonte, Minas Gerais, Brasil, and neither with a Tim or Vivo sim the
Evo 3D is getting signals in wcdma mode only. In my old T-Mobile G2, both Vivo
and Tim sim are getting the "4g" signal. According to the Gsmarena specs of the
T-Mobile G2, it has HSDPA at 1700/2100mhz. And it gets the 4g.
And all the variations of the Evo 3D have HSDPA at 2100. So it should be getting the 4g.
At the back of the box, says HSPA/WCDMA 900/AWS/2100 Mhz.
Is it a question of baseband or rom ?
Any help ?
Please use the Q&A Forum for questions Thanks

Hi.
Just to update here.
At the testing menu *#*#4636#*#*, submenu phone information, pressing hard button menu and selecting radio band as Euro, and any other band, i don't get 3g/4g.
Even with Wcdma only and cyphering on or off.
The thing is that at my old T-mo G2 both Tim and Vivo sims get the 4g signal.
deadlocked007 said:
That's only because of marketing so technically you still have 4g but it should just say 3g to make sure test the speed on the g2 then test the speed on the evo.

It's not a question of speeds, here in Brasil speeds are limited by provider.
The thing is that it's not connecting on Wcdma/HSPA....
What frequency are your providers broadcasting at?
Sent from my PG86100 using Tapatalk
HSPA, Tim is at 850 and 2100, and Vivo on 2100.
And at a moment last night, right before i slept, i tried changing sims again, and the Evo
got connected at the HSPA network and showed the H icon. But, it haven't got the H
again yet. I did port my line from Tim to Vivo, but i don't think it's a problem as both sims
connect at the HSPA network on the G2.
I just bought an unlocked samsung sgh i-777 (at&t) from ebay and currently using vodafone nz.
Here are the vodafone frequencies..
Vodafone's mobile network operates on the following frequencies:
A 2G GSM voice network on 900/1800MHz (almost every GSM mobile should work on these frequencies)
A 2G GPRS data network on 900/1800MHz
A 3G UMTS data network for voice, video calls and data on 2100MHz
A 3G HSDPA network on 2100MHz
Although i am able to get internet on my phone and its not too slow (6.5mbps), my galaxy mini used to be alot faster (atleast 10mbps). My internet is some areas is jus reaaally slow where my mini used to do great.. I was just wondering if there is something i can do to improve the 3G ? my internet is some areas is jus reaaally slow where my mini used to do great..
any help would be appreciated. thanks

Try flashing another modem. Of course, your speeds may vary greatly depending on your exact location.
