hi
Is there access to your SIM card In nexsus one from T-Mobile؟?
I want to buy the device from the U.S. and I live outside of America do not care if the device is locked to T-Mobile
Important to have a sim card entrance
think you

Yes, its quite easy to change the SIM - I did it when I was in Europe last year.
The 3G access is specific to certain bands, so make sure you do your homework first, or you may not have 3G access...

MDA Vario 2 in Korea

please, anyone can tell me can I use my phone in Korea? actually I've just moved to Korea, and as I checked with my country SIM card and my friend SIM card (from Bulgaria) , the phone worked as roaming and i could make a call, so I think that it's possible to use my phone with the service here, but when I borowed a SK telecom SIM card from my friend's phone and put it into my phone, the phone didnt work, so please tell me do I have to unlock, install or register anything to use the service here (my phone's already unlocked SIM)?

Hello
From what I know is, Korea use CDMA signal instead of WCDMA (European 3G signal) there for I'm afraid that you will need to get a phone in korea.

but actually I could connect to the network here with other country SIM card (not korean)

can't register on network with g1

I unlocked successfuly my tmobile g1 coming from usa, but now I have no signal and unable to register on network.when I go in settings,wireless control,,mobile networks.when i ask for available networks i have this error message:"error while searching for networks".even when i choose select automatically i have this:"your sim card does not allow a connection to this network".we have GSM, GPRS, and EDGE in my country.Do you have any idea?thanks!
It's your SIM card being locked to a specific network. You might have to contact your vendor.
I don't understand,my sim card locked?I don't have pin code.you are talking about my foreign sim card(non tmobile?)could you explain more?
I don't know why either. I just know that is what happens. I had the same problem with my SIM too when I went on vacation. But I didn't bother trying to fix it. Since I brought the local SIM to use because I didn't want to pay the international rates.

[Q]Do i need a new sim card?

have a 2 Optimus quantum phones, one never gets 3g, or H, data doesn't seem to work at all (i changed APN settings to fido)
could this be do to old sim card? its really old before 3g network existed, when edge was early
other phone works ok, setup in identical way but sim card is newer from an iPhone 3g i had
so as question above says could it just be due to an old sim card?
Swap the working SIM card between phones and you will have your answer
I think you guessed it. My network (Rogers) required new SIM cards to work on their 3G network. Your carrier may have the same situation.
In my case, Rogers was happy to swap the old SIM for a new one.

[Q] Can I use a 3G SIM chip on a -possible to release- Nexus 4 LTE-enabled?

As the title says... Mostly I need to know in general if I´d be able to use my 3G sim into a LTE phone. Need to know this because Google is probably releasing a Nexus 4 phone On Google I/O which is said to be TLE enabled and will have 32 gb for storage.
Honestly i only care about the 32 gigs because I live in Costa Rica, Central America and LTE is still not avaiable here, and who knows when will it arrive so I'll stay with my 3G sim card for an undefined time. It's important to mention that plans in my country do not restrict using my sim card on a certain phone, or viceversa, everything is totally unlocked (at least with my phone company) so I can do whatever i want concerning with switching betwween phones and stuff. So, If an LTE phone can read my 3g sim card i'd surely buying this awesome phone. I use A LOT my actual phone for music playback and that's why my focus is on the huge 32 gb storage.
So, again, can I use a 3G sim card on a LTE phone and have access to the normal phone functions (calls, messaging, 3G internet...)??????
I'm asking this because on my research on Internet I found people who say it does is possible and a lot who say it isn't...
Unless it is a CDMA device, a "3G" SIM will work fine, my current SIM card is "3G" (Straight Talk doesn't offer LTE) and the current Nexus 4 is capable of LTE...I'm not having any issues.
Now I've read sometimes older SIMs have issues with newer phones but I haven't had that issue.
so if there's a problem i'd just need to update my old 3g sim for a new one and that shoud work for any phone marketed as LTE or 4g???

Hi guys
I have got a Galaxy S4 i9505 with a label that it's a European model and will works with sims in the europe. Could someone please help me on what does that mean? I have tried searching and reading but it's all conflicting statements.
1) Do I activate it with my UK sim card and then it can be used anywhere in the world?
2) Do I take my UK sim card everywhere I travel around the world and first switch on the device with UK sim and then later on swap the sim with local to use the phone?
3) Can I use the phone normally and then use a software which can enable the phone to use any sim in the world?
Thanks
