I have a quick question regarding GSM bands.
I'm using the Bell i9000M (on 850/1900 band) right now, and planning on unlocking my phone and taking it to Spain for a vacation.
In Spain the GSM band they use is 900/1800. I know my phone is compatible with GSM 850/900/1800/1900 and HSDPA 900/1900/2100. Will my phone search for those bands and switch automatically when I put in a SIM card from Spain? Or is there something that I need to configure within the phone?
Thanks!
Hi all,
I've spent the last few hours searching google and this forum, but to no avail. Any help would be appreciated.
I have a LG Optimus Black but don't have the box to know the specifications. I want to buy a T-mobile sim card for my phone, but can't figure out if it will support T-mobile's 1700/2100 3G network. According to GsmArena (and other sites) there is 2 versions of the P970 one with the 1900 Mhz band and one with the 1700 band, I don't know which one my phone is.
How can I know which band my phone supports? I have a model number, IMEI, and S/N. Is there any app or program that would be able to tell me what band my phone supports?
Thanks in advance.

Contact your nearest LG service center and ask em you want to talk to their technical not costumer service.

yeah, by providing your IMEI and product code, they will know the specific specification.
I also have US T-mobile HTC Sensation, frequency works very well in my country (900/1800/2100)

I called up they claimed that since it's a international phone they don't know. Perhaps I'll try calling tomorrow LG in the UK.

I just called LG in the UK they also claim they don't know. This is getting kind of annoying. I want to know if I can buy a T-mobile sim card.
I have the LG P970 and with my t-mobile USA Sim, 3G does not work. It only uses the GSM Edge signal. It works fine with AT&T 3G.

So you have the 1900 Mhz version of the P970, since At&t's UMTS network uses 850/1900.
Humm just bring your phone to T-mobile booth or branch and test it

T-Mobile USA's 3G/4G(UMTS/HSPA+) AWS REQUIRES 1700mhz + 2100mhz combined. If your phone has only 1700mhz, it won't work (and no, it won't work "1/2"). You'll just get defaulted to EDGE speeds (which practically all GSM phones support)
the
P970 has HSDPA 900 / 1700 / 2100
and the P970H has HSDPA 900 / 1900 / 2100
so i think the original version would work...
Came back from the U.S and AT&T 3G works fine.
Hi, wondering if anyone has taken it overseas such as tokyo or europe? Does it have the correct frequencies? Can this be unlocked to use international sim?
Asking regarding ATT LTE model.

Europe and Asia mostly uses the 2100MHz band which the 4G LTE does not have so most likely, you won't be able to use it.

According to their website specs... 2100 mhz is supported. Dont care about 4g speeds. Only hspda or 3g is fine overseas... It also says international supported, but not sure about if its sim locked.

The 2100 band is for LTE not for UTMS where the rest of the world is still kinda in. The LTE version surely does not work in South East Asia, Hong Kong or Macau, I brought one with me on my trip 2 weeks ago.

I c i c. Thanks. I guess skyrocket cant work as well in asia then.... Since they are based on the same chip. For your tablet... Did you unlock it and didnt even pick up the signal?
Was thinking about free skyrocket plus 8.9 tablet...
Ehcan, did it work with 3g freq in asia though? I know no lte.. But want to know if it works with the att 8.9 unlocked.
I am in South Korea and will be moving to the UK soon.
I have the SU600 on SKT in Korea. It is rooted and I'm running Kangs CM on 4.0.3.
If I buy a UK sim card when I arrive, will the phone work fine for calls/messaging/data? I looked on gsmarena and the 2G frequencies seem to match up. But the 3G on the phone is HSDPA, but GSM arena says the UK needs UMTS 2100. Will it still work?
Would I need to get it unlocked in Korea before I leave?
Thank you

From my experience, having a custom rom is effectively same as having a sim unlocked phone. So based on what you wrote, I have every expectation that you'll successfully use at least the 2g network in UK.
I bought my su660 in Korea too and now I am using it in the US. It turned out, however, that I cannot use the 3g hspa network here with T-Mobile because they require phones having both 1900 & 2100 bands. So I am stuck with just 2G for now.
So I would do careful research on what bands UK operators use before you head on over, especially if you really need 3g speed and if you are not planning on buying another phone anytime soon. I hope you will be in better luck than me.
Bon voyage and good luck!

You are wrong sim unlock has nothing to do with root/custom ROM. He has to unlock the SIM before.
And to unlock you need a STOCK LG ROM, froyo or gingerbread, as it needs lge hidden menu which isn't present in custom ROMs.
I unlocked last week I had to reflash a froyo LG Stock ROM.
Some people say that putting a SIM card from a different network pops up the unlock option at boot but couldn't try.

Thanks for pointing that out. I guess mine must have been already sim unlocked when I bought it cuz sim unlock menu never came up for me.

I imported an ATT Atrix for using in Mexico with Telcel Carrier, and when I first inserted the Telcel Sim Card, the Sim Unlock Menu popped. So yes, maybe your Optimux 2x is already unlocked.
Anyway, you can unlock your phone anytime and in anyplace. Just insert a sim card from another Carrier Company and the option should be showed.

Cool, I will check the SIM unlock then.
How about the frequencies it uses?
According to gsmarena the SU660 has 2G Network GSM 850 / 900 / 1800 / 1900 3G Network HSDPA
The UK frequencies for 2G are Required GSM 900. Recommended GSM 900 and GSM 1800. and 3G Required UMTS 2100.
I'm guessing that this means the 2G will work, but 3G won't? Can someone tell me if this is correct, I don't fully understand what it means with the SU660 having HSDPA. Is this a different to UMTS??
Hsdpa is UMTS.

GSM arena has insufficient info. Check out http://www.phonegg.com/compare/27/LG-Optimus-2X-vs-LG-Optimus-2X-SU660.html
From what I see there and what you described about UK operators, it seems like you will be able to use 3g.

That could be a bit misleading because the 2x I have here in Australia has 2100 and 900 but no 850. 850 is used exclusively by one carrier here.
So, the link may depend on in which region the 2x is sold.

Sorry for the OT, but can you please help us to translate some Korean statement by LG HQ? Google translator is not very good in this...

I am thinking about buying this phone, I am on a contract with Three so want to use that sim. Can I use that sim in this phone as I am concerned about the different bands, according to GSMArena the LTE version does not have the 1900mhz band. What band does Three use for it's 3G? It's all very confusing and I want to know before I purchase. I heard from somewhere it uses the 2100mhz band, which will be ok.
Many thanks!

3 uses 1800 for 2G and 2100 for 3G. Both of which are supported by both varients of the S3.
