Hey guys. I was recently playing around with my girlfriend's Optimus One (from T-Mobile) and it doesn't get 3G signals at all. I think she gets edge, but that's as good as it's going to get. She has perfect wifi, but her device is unable to connect to 3G. I read that it operates with 2100 and 1700 bands, but I'm not sure what that entirely means and how to fix the problem. Any suggestions?

Hi All,
Few months ago, I've bought an HTC Touch Pro from Newpan Tellcom in Israel.
Yesterday I've left my Mobile Carrier (Cellcom) and I moved to Pelephone - Other Mobile Carrier.
Since I moved to Pelephone I've some reception/signal problems.
I know that Pelephone are working with UMTS/HSPA 850+2100 MHZ bands,
but my Touch Pro supports only HSPA/WCDMA 900/2100 MHz bands.
When I've tried to switch to UMTS band, the only option that I've got was UMTS 2100+800 MHZ bands.
In order to have good reception, I must be connected to UMTS/HSPA 850+2100 MHZ bands.
I've tried to Upgrade my phone's ROM to the latest EnergyROM 'Phoenix 2' buit 21877 and still I've reception problem.
Is there any way to solve this issue?
Please Help Me!
I think Touch Pro is known to be weak on radio reception. I myself in US am suffering the same problem. While my wife's Samsung phone gets four bars around our house, I gets only one on my Fuze. And my data connection keeps bouncing between 3G and EDGE or even GPRS.
I did some googling about the Fuze receptionn problem, and it seems to me that a lot of people suffer the same problem.

But somebody in US claimed that a newer version of SIM card from AT&T will help the problem a little, and it was confirmed by some of the people went for the "solution", while the rest think it does not work.

Don't know if the same possibility is available in Israel.
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
I bought the unlock code for my Optimus T / v10h / P509 running rooted stock 2.2/Froyo and it worked, then I took out my T-Mobile SIM card and tried my girl friends Telus SIM, and it gets no signal. If she enters the IMEI into the thing on their website, it says the device is imcompatable. As far as I can tell, the phone is technically compatable with Telus Mobility's network, even though my T-Mobile devices roam on Roger's when using my SIM. Even checked the band on her LG Breeze and it's the same crap that spec sheets give for the radios in the Optimus One family. Like wise, Telus sells an Optimus One / P500h / v10g device running Gingerbread! Roger's and Telus even use the same bloody frequency for this hardware AFAICT!
When we load her Telus SIM, every thing works, no warnings or messages, it just reports NO SERVICE and gets no signal.
Thought that maybe /etc/apns-conf.xml was missing the info for Telus, and it was, so I copied the entry from my ASUS Transformer, and no luck on reboot. I'm not sure if that's needed for SMS or just mobile data and MMS though but know it wouldn't hurt.
She has a pre-paid texting setup with Telus and a GSM feature phone. Not sure how that impacts swapping her SIM to my old Optimus T; I've always been on contract with voice/text/data but I don't see any issue, since I've seen pre-paid versions of the Optimus One and adding data isn't worth it if it doesn't work.
I've considered trying to find the Telus firmware and have her try flashing it but I'm hesitent, her feature phone does texting fine and via WiFi the Optimus T does at least handle the "Smart" phone stuff. We do have a nandroid backup via CWM5.
Does anyone have any ideas of how to get texting to work on it?

Optimus t is AWS phone, with 2G/Edge/GSM capability
telus network is UMTS 3G and does not have a 2G/Edge backup
telus old network is CDMA
So I take it that means the OT is expecting to find a 2G GSM/GPRS/EDGE network on the 850/1900 band and to find a 3G UMTS/HSPA+ network on the 1700/2100 band (UMTS band IV); and not smart enough to deal with finding Telus's 3G UMTS/HSPA+ network on 850/1900 instead of an EDGE network, lovely.
Any clue if something like that would normally be built into the cellular radios hardware, or implemented in the firmware?
When I looked up her Breeze, it was marked as GSM 850/900/1800/1900 and UMTS/HSDPA 900/2100, so I assumed if that worked with Telus, so would the Optimus T. Guess I was a tad dumb there :-/.

Hello All,
Has anyone had any luck getting a Huawei U8860 to work on T-Mobile in the US?
Here are the details on the phone:
It was a Chinese model that I upgraded to the worldwide Android 2.3 ROM from the huawei site.
I have voice and 2G Edge Data working, but I can't get 3G.
It is a quad-band (GSM 850/900/1800/1900) device.
The phone says it supports 3GGPRS, HSPA and WCDMA. I also read a CNET review where they were unable to get 3G and were limited to 2G Edge.
Has anyone had any luck with this device in the US? T-Mobile or AT&T?
Thanks
3g connectivity
I am in South America, and I am experiencing the same problem. No 3G connection! Please help!!
So far I've tried two officicial ROMs (2.3 and 4.0) withou luck. In fact, I was hoping that the problem was fixed with the new official ROM released today, but I am still getting just EDGE connectivity.
Help!!
I think the problem is the radios on the phone. I did more reading, and it appears that it does not support the HSPA frequencies, so it cannot do 3G in the US. Apparently, the only penta-band phone that does 3G world wide is the Galaxy Nexus. Oh well, the phone is still usable, I just have to suffer through 2G speeds.
Hello,
Last month my dad gave me as a gift a LG L70 bought from the US. I live in Romania and It was locked on MetroPCS, but I went to a local shop here in Romania and managed to unlock it. It works very nice and smooth, with one single problem: I can't manage to get the 3G/4G network to work on it. Everytime I open up the mobile data connection it remain stuck on 2G (showing E). Any ideas how I can get this to work?
The frequencies for the 3G network here in Romania, for my carrier are: 2100 and 900, but 900 is also used for the 2G network. The phone supports 900 Mhz and also the frequency for 4G, but both the 3G and the 4G won't work.
Many thanks!
