I own a GT-I9020t (tmobile) and just moved to south korea. I think I've read that the phone should still work by swapping SIM cards with a Korean carrier (like KT). Just wondering if it is possible or not.
Phone comes unlocked. You can put any sim card and you wont face any problems
So if I take my T-Mobile GSM Nexus S to say Korea, it will work by simply swapping to a Korean SIM Card? Like 3G and phone all works?
I thought there were some regulations like getting permission from the government to use foreign phones (like some Koreans had to do that pre-iPhone era).
Thanks!
I dunno about 3g, you should check mobile network frequencies in Korea. But yeah, you can use any unlocked GSM phone with any sim card. I live in the middle east, my phone is 9020t which I bought from the states. Never had problems with it even when swapping sim cards during my trips to Europe.

As long as radio frequencies are same, it should work right? So if I go to Korea and Korean mobile provider has these frequencies, it should work?
T-Mobile USA owns licenses to operate a 1900 MHz GSM (Global System for Mobile Communications) PCS (Personal Communications Service) digital cellular network and a 1700 MHz/2100 MHz UMTS AWS (Advanced Wireless Services) digital cellular network that cover areas of the continental United States, Alaska, Hawaii, Puerto Rico and the US Virgin Islands. T-Mobile USA provides coverage in areas in which it does not own radio frequency spectrum licenses via roaming agreements with other operators of compatible networks.

T mobile uses 850-900-1800-2100 for 2g and 900-1700-2100 for 3g. You shouldn't worry about voice since its a quad band and works in every country around the world. If any mobile network provider has the same numbers above for 3g, then you're ok
It should work fine in Korea. It's just a matter of acquiring the local sim (or USIM as they call it)or registering the phone and I'm not sure how easy it is to do it.

Hi guys and girls, I've got a bit of an issue.
My Niki100 (HTC Touch Dual) won't seem to read my shiny new South Korean USIM.
The phone is originally from Australia, and has been quite happy roaming around on the 2100mhz 3G network here in South Korea using my Australian (3G) USIM, but it won't read the South Korean USIM.
It reads enough to pull up the number from the USIM, which shows in phone services, but it won't register on the network at all.
I was expecting it to play nicely and just forget about the GSM part of the phone and continue connecting on the UMTS (WCDMA) band, but apparently not.
I've tried a variety of ROM's and Radios without results.
Any ideas?
EDIT:
Solved: It was a combination of needing a new Sim Manager version, and the retarded IMIE lock South Korea puts on all foreign phones.
all,
I have been travelling back and forth to Mexico, I can put my pre-paid Telcel Sim in my phone and the "talk" portion works perfectly but I have no access to Mobile data even though the Telcel Rep says I do.
Is this because the T-Mobile Sensation UTMS frequency is 2100Mhz (or so I have been told) and Telcel is 1900Mhz (again so I have been told). or is it for some other reason?.
I have both the T-Mobile and the international unlocked version. I have the latter because, in my excitement, I didn't take care to find out if it will work on T-Mobile's 3G speeds. To my dismay, it doesn't, and I have an extra phone.
I'm wondering if it will work on any other carrier's 3G/4G data speeds. Searching forums and support threads haven't gotten me any answers. Any help at all would be appreciated.
I bought mine in Britain and am using it quite happily here in Japan. T-Mobile USA has a relatively rare frequency band internationally; I think as long as you have 2100MHz and 900MHz bands, which this phone has, there should be an operator in almost every country that the phone will work on. In fact, it should work on most operators in most countries.
The phone has 850/900/2100 MHz bands for 3G; T-Mobile runs "4G" (actually 3G) on 1700/2100 aka AWS - this requires BOTH bands to be present in the phone, which is why the One S doesn't work. T-Mo USA also has 1900MHz, again not present in the One S. Can you get EDGE 2G data, which should be possible on 850MHz?
In the USA, it should work on AT&T, as they use 850MHz for 3G. Maybe you can find someone who will lend you a SIM to check it.
In Europe & Asia, it should generally work no problem.
Based on what I have read, given that the Rogers XT925 operates on the following bands:
Rogers version is GSM/UMTS - 850/900/1800/1900 and LTE : BAND 4 (700) and BAND 17 AWS (1700)
It is therefore impossible for it to work in the USA on Verizons network on either CDMA (which the phone does not support) or LTE (which it supports but the wrong band, Verizon supports 700 Band 13)
Can anyone confirm this? If it is possible to operate this phone on Verizon please let me know. I have a Verizon account and an AT&T account and the phone works on the AT&T account, but not the Verizon. My problem is that AT&T has recently blocked the IMEI on TWO of my Rogers phones that I travel with, with no explanation other than that they are being recognized as 2G phones and cannot get service on AT&T (which is BS, because I can roam with my Rogers SIM from my Galaxy S3 onto AT&T just fine), so AT&T is clearly blocking IMEI's of phones that come from other providers and are unlocked. I cannot see how this is good business for AT&T, or even legal, and I imagine one day there will be a class action suit to stop this practice.
My two cents...

No the rogers hd never work on Verizon ... the rogers don't have CDMA ... and LTE is on the wrong band ... There are no solution...
Yes some friend have same problem as you ... have a rogers simcard ... use a little on the ATT network ... switch to ATT simcard ... and phone don't work ... really a strange issue ...
I am traving to Cancun Mexico on the 23 of june. I currently have an AT&T SIM inserted into my SIM Unlocked S8+. I know AT&T has service in Mexico, but as far as I know the best they got is 3G. I was wondering if I was to go outside out of their AT&T coverage and into another companies coverage while in Mexico Whether it be CDMA or GSM. Would the phone work on all their network bands, or would it be only GSM bands because of the AT&T SIM inserted? Another option I thought about was getting a different SIM in mexico. That might be a better option just in case roaming on my phone is not possible with other carriers out there that aren't GSM supported.
Any help will be greatly appreciated. Really hope someone has the answer to my question, because google sure didn't lol.
Bumb
Yes. It works fine. I live in Southern California and when you get close enough to the Tijuana border in San Diego you may start to roam on a Mexican network. (Unlocked S8+ here)
