 |
|
| Google's plan was to release the Nexus One worldwide SIM free, even to those who buy it on contract. I wonder is it SIM locked in Korea though? I have a feeling KT wouldn't sell it any other being the foreigner haters that they are.... |

| from what i understand, yes there is some sort of lock on it put in place by htc korea. I'm going to the states soon for vacation and inquired kt about my situation if I could use my phone over there with just a sim swap. I was told to call htc korea. They just asked for my phone number and my phone imei number and they gave me a unlock code that I should enter when I insert the foreign sim card and turn the phone on. I haven't tried it yet, but I'll update in a couple of days if it works. |

| in korea it doesn't use sim cards anyway. Their networks are on the CDMA upgrade path. Phones with sim cards only use them for international roaming. |

I see this misinformation floating around a bit on these forums but it's not really true. Phones here with SIM cards do in fact use them, and not all phones here use CDMA. It's true that the majority of the phones here use CDMA, but it's not the only protocol available for cell phones. Take the iphone for example, in korea it uses UTMS (3g) and not CDMA (it doesn't even support CDMA). As far as i know, the Nexus One also does not support cdmA
and yes UMTS is also known as W-CDMA, but it's not the same as the CDMA2000 standard normally used in korea, it's a part of GSM.
If you don't think SIM cards work in korea, try swapping your SIM card with some one elses, , by that logic it should still work no matter what SIM card was in it, but it doesn't. |

| I just pulled the sim card out of my lgsh150a it worked fine. CDMA and gsm have different 3G protocols. It isn't part of gsm they are two totally different upgrade paths. They don't use cdma2000 but they follow that path which is separate from the gsm path |

interesting, because when I remove the SIM card from my girlfriend's Sky phone it doesn't work, same for my iPhone. I even tried swapping the two cards, and it even gave her my phone number. I'm not sure why your phone would be working, did you try turning it on and off after removing the card? Or try making a call?
You sure that's a SIM card and not one of those cards used for banking? |

actually a few minutes later it stopped working. I was tied up and couldn't post another message at that time. But oddly it still worked for a few minutes without the card.
I think at one point there may have been dual mode phones like I described, but perhaps those have been replaced. |

I'm curious too.
My old Anycall flip phone would stop working without the sim, but when i swapped in a friend's sim her contacts and phone #'s populated the phone, and it worked using her #! We were both on SK btw.
Isn't that exactly how a GSM sim card works back home?
I'm hoping I can unlock my galaxy and take it back home but I don't know if it will work with GSM or CDMA carriers back home. I assume the Nexus One would be similar... |
