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!

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
Hi everybody.
I purchased a unlocked gsm optimus t (t-mobile) in USA last week. Well, in my country we have a 850/1900 wcdma band (it seems the same at USA), but, i can´t conect to 3G network.
Searching for the phone specs, i find it the optimus t work in 1700/2100 network, it´s that correct??. If the answer is yes, it is possible to change wcdma frequency in this phone??.
Thanks for you help.
Pd: I read if i install a correct firmware for my country (Chile) is possible to change it.
I don't think so. There are 2 versions of the phone. I've bought mine in Chile, and no matter what ROM I use, I still can connect to the 3G network.
However, I think you should keep your phone and wait for Nextel or VTR networks to become operational, which will work on those bands.
You should see those 3G networks doing a network search on your mobile.

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.
I have looked for days now across multiple forums to get some insight on this issue:
I want to use my Thunderbolt in Thailand. Haven't found any threads that speak of success, only conjecture that it won't work.
Homework I've done (unless i understand it incorrectly):
- Verizon 3G operates on the 850 / 1900 mhz cdma band. Radio Frequency Summary
" The following is a list of known frequencies which Verizon employs in the United States:
Frequencies used on the Verizon Network
Frequency Protocol Class
850 MHz 1xRTT/EV-DO/eHRPD 3G
1900 MHz 1xRTT/EV-DO/eHRPD 3G
700 MHz LTE 4G
1700/2100 MHz(AWS) LTE 4G"
- Truemove, a popular mobile company in Thailand has early links to Verizon and their 3G service operates on the 850mhz wcdma band
"What should I do if I want to use TrueMove 3G service but I don’t have a 3G 850 MHz mobile phone?
Basically, it’s not that all mobile phones work on any band. Each 3G compatible mobile phone supports different bands. For example, if you have a 3G 2.1 GHz or 900 MHz or 2G mobile phone, you will not be able to use TrueMove 3G service because TrueMove offers 3G service on 850 MHz band.
If you want to enjoy TrueMove 3G service, it is recommended that you buy a 3G WCDMA 850 MHz mobile phone or visit any True Shops and ask for a 3G compatible mobile phone. True Shops also sell different smartphones that support different mobile platforms e.g. iPhone 3G/3GS, BlackBerry Bold 900/Bold 9700 and Motorola Milestone."
- I spoke with verizon after reading other forums about 'unlocking' thunderbolts and was told that the thunderbolt comes unlocked, so unlocking wouldn't be necessary anyway.
- Lastly, it seems that many people have successfully put a 3G SIM into a 4G SIM slot on there phone and received 3G service.
....So what am I missing? What would prevent me from being able to use my Thunderbolt in Thailand for simple 3G service if the carrier (Truemove) works on cdma based bands? What extra might I have to do to get it to work?
PS: Sorry I can't insert the links directly in the post. Not allowed since this is my first post.
Thanks for any help
Hi,
Recently I happen to move to India from USA. I had Samsung Galaxy S3 - SGH i747 purchased in in US, which was under 2 year contract. I tried to call AT&T guys to give me unlock code but they didn't give me since my contract was not over.
I moved to India and tried to unlock my phone from local shop. I am able to make/receive calls now having these issues.
1. 3G is not working . When I see different available bands in my phone using *#2263#, it shows WCDMA 850, 900, 1700, 1900 and WCDMS IMT2000 under WCDMA band preferences. I am using Vodafone in India which runs on UMTS 2100. I visited Vodafone store couple of times but they are not able to help me. How do I get 2100 frequency in my phone ?
2. Currently I have set preference to run my phone on GSM Band so 2G is working. There are certain areas in my city where Vodafone 2G is also not working. In those areas, I don't receive any call even though I have very good network coverage. I tried switching off my mobile network in case I can receive calls but its of no help.
Request for your to resolve this. I am fed up with this nice working phone and need to purchase new one if these issues don't get resolved.
Thanks
