Re: Which standard in South Korea?

So you, ConstantineM See Profile, are saying that the Maguro Galaxy Nexus will work there. Right?

According to the following page from GSM Association, any phone that's designed to work on a European UMTS frequency, 2100 (also known as W-CDMA 2100), would also work in South Korea. The GSM/HSPA+ Galaxy Nexus, GT-I9250, happens to be one such phone (I own one, BTW).

Wikipedia article about UMTS Frequency Bands also confirms that Europe and (some parts of) Asia share the same band.

»en.wikipedia.org/wiki/UMTS_frequency_bands

And just to make it clear about the whole fuss regarding GSM vs. UMTS: if you disable UMTS on your phone, via, "Use only 2G networks (Saves battery)" in "Mobile network settings", or if you have a GSM-only phone (with no UMTS support), then your phone won't work in South Korea at all, because they have no GSM networks. I hope this clarifies any issues you might have regarding the "conflicting answers being passed around here in this thread".

P.S. Google Nexus 4 release is almost here; might as well wait until Tuesday, 13th Nov, and get it direct from Google for 299$ (8GB) or 349$ (16GB). :-)

Well... here's to hoping that the dev team behind AOKP can get the AOSP code of the Nexus 4 merged into the codebase so I can send him along with a good and decent AOKP-based ROM.

The reason why I was thinking about the Galaxy Nexus was because device support for it is very mature in the AOSP scene.

The miscommunication here is the SIM/GSM is used interchangeably all over the world and ConM thinks otherwise.

terms SIM, GSM and UMTS are not interchangeable!

South Korea and Japan are specifically different because they never had GSM networks; elsewhere in the world, I'm not specifically aware of any GSM networks already being shut down (so, suggesting a GSM phone for Europe won't be wrong at all), although I do recall that several operators that have started out since 3G UMTS has already been available, are likewise offering a UMTS-only service with no GSM (»three.co.uk, »WINDmobile.ca and »mobilicity.ca).

Also, some operators switched to UMTS from some other crappy 3G (»bell.ca and »telus.ca, they have a shared UMTS network, IIRC); Verizon delayed the switch, but went directly with LTE with no UMTS. When I was in Canada in 2008/2010, I had an unlocked GSM phone from AT&T, Sony Ericsson W810i, and it wouldn't work with Bell or Telus, but would only work with Fido and Rogers.

And FYI: SIM cards don't mean GSM, either. There are some SIM cards that won't work in any GSM, UMTS or LTE phone, so, even without UMTS: for sure SIM and GSM aren't interchangeable terms at all, I'm again not sure what made you to believe they were.

Let me put it this way: I need a replacement phone for Verizon; you come by and suggest that I can just get a GSM phone, since Verizon has nationwide LTE, and LTE is a GSM descendant -- please keep such advice to yourself, cause it's wrong.

South Korea has no GSM, period.

So it really comes down to forget about getting him a phone now. Let him sort it out at the US Military Base Exchange Store once he gets to South Korea.

I would hate to have him spend $400 on a phone he can't use.

And here I thought that GSM was the world standard and we in the US were the weird ones.

Vz is Vodafone and does support GSM service as well as LTE however, using the CDMA phone in conjunction with sim chip LTE is also possible... But Vz is no SKTelcom.

GSM is the world standard; US, Korea and Japan are the "weird" ones.

I don't understand why you're confused, though. Everyone told you that an HSPA+ Galaxy Nexus and an HSPA+ Google Nexus 4 will both work in South Korea (unless you disable 3G to save battery).

What a bunch of ambiguous nonsense taken completely out of context. You HAVE to use a cdmaOne/whatever phone on Verizon nationwide network, precisely because VZ is not Vodafone, and VZ is not GSM, and a GSM phone won't work in the US on Verizon network. I'm done here.

No one is claiming a GSM phone will work on Verizon, However Verizon has a 310 assignment so they can bill international US people traveling abroad using their version of GAIT, or GSM. Also sorry LTE is UMTS ver 9 i believe. So yes verizon is a GSM network.
