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 already unlock 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.

sim card icon

Hello,
I have recently bought a samsung galaxy S from a singaporean friend of mine, i am in malaysia and I was using a Digi network and everything worked fine so I assumed my phone is not SIM locked.
Now I am going back to egypt but when I put my egyptian SIM card I got an icon of a sim card with a red exclamation mark next to it on the right side of the notification bar. There is no error message or anything. What does this mean? is my phone SIM locked or is my SIM card defective? I tried searching for the problem online but I didn't get any solid answer.
Thank you

I got that error when I forgot to insert the pin number of the card and skipped through the loading process. Reboot your phone and wait for the pin request.

No sim card

I brought S4 just another day and when I insert sim card the phone says "No sim Card" but I inserted it already!
Its micro sim i'm buying another sim card today and see if it works,
Will customer service fix this if the problem is in the phone ? If yes then is it covered by warranty ?
Any help? maybe its software problem

And how exactly he should or anyone should know what's exactly your problem? Can be hardware or the simcard. This is up to you to find out.
First try a new simcard , and try to get one micro sim factory cut if you can, if still nothing means is hardware.

Did you put it in wrong?

You have the answer on this topic, if doesn't work with any simcard, bring it back.

GT I9505 doesn't detect LTE sim, works fine with 3g Sim
Hello all !
I own a 2.5 year old GT i9505 (LTE variant) which works completely fine with a 3g Sim but the "Sim Card not inserted" error appears as soon as a 4g Compatible Sim is inserted. Could this be a modem issue ?
I live in India (got the phone from Europe) and have been using 3g services without any hitch for the past 2 years. Vodafone recently launched 4G services here and my phone doesn't detect the new 4G Sim card .
My phone shows the LTE/WCDMA/GSM modes but doesn't detect the Sim card.
Tried with another Sim from the store that doesnt work either.
Details :
AP: I9505XXUHOJ2
CP: I9505XXUHOJ2
CSC: I9505EURHOJ1
All ideas and solutions are appreciated.

It's possible that there is something wrong with the phone's sim card reader. You could replace the reader for not a lot of money and it's easy to do yourself.

Maybe your phone is unable to detect LTE Networks from Vodafone India because from what I research, India uses TDD-LTE. You could Google-d LTE bands that used in India and compare it with your phone's supported LTE bands.

Thanks for your reply.
I considered that option but a 3g sim works perfectly. Do you still think it would help ?

I guess I am just lucky my phone supports both.

Still no luck !

I don't know that much about sim card technology. Have you tried the LTE sim card in a very old phone to see if the old phone detects the sim?

I did infact it works with every phone except this one.

Leads me to conclude it is the sim reader or motherboard if no LTE SIM cards work. Doesn't seem like software.

Would some one give me a hand setting my Note 3 up.

So I purchased a used note 3 ( N900A )
I just switch to straight talk. So I had a full size sim and cut it down to fit my note 3 . When I try to go into my apn setting it says insert a sim or something like that.
I know the sims registering , to the phone I can read stuff from it.
So has any one went down the road I am . Is my sim locked or something like that.
Also there is an app called "Sim App." it will first say icc-id and give what looks like about 15-16 numbers then click ok it reads imei check sum gives 4 digits next reads random number gives 8 numbers.
then asks for an unlock code . If entered wrong it will say you have X amount of trys lefts.
Does this have anything to do with why my sim card is not registering to the phone?

Do any sim card works in the phone? Does your sim card work in other phones? Was the phone tested with a sim card before purchase? Was the phone locked to AT&T?

Yes if I switch the card to the other phone . It works.
Im not sure if this matters the orginal phone was a throw away`alcatel. Its not a smart phone.

Are you using the SIM card in another phone that also uses a micro sim? Does the note 3 recognize any SIM cards?

I only have this one sim .
The note is reading the sim card with certain aps . You know how if you up power up a phone , missing a sim it will say so if you pull down the top banner usually with a message like insert sim. When you pull down the top banner it doesn't say that . There is no warning about missing a sim . So it recognizes it has one . I can read stuff off the sim card when i open certain aps that are meant to access sim cards but when I go to change APN setting it will say insert sim card to access network settings.

Without another sim card to try in the phone, it could be the way the sim card was cut or there is something wrong with the phone.
Is the phone sim unlocked? Did you try a sim card in the phone before buying it?

I dont think the phones sim is unlocked.
No I didnt try a sim . It was from a family member so Im not to worried. The sim card works in my throw away straight talk phone.
How do you unlock the phones sim?
BTW thank you for your help.

In order to determine if the phone is sim unlocked, power off the phone, insert a sim from another carrier, and power up the phone. If phone asks for a network unlock code, the phone is not sim unlocked and you will need to get an unlock code.
Was the Note 3 n900a from AT&T?
