[Q] German i9300 with China Telecom - Galaxy S III Q&A, Help & Troubleshooting

Hello together,
I have a S3 from German Telekom. It's unlocked and not yet rooted.
Now I am in China and bought a Prepaid Card with 5GB of Traffic from China Telecom.
It connects to the network, coverage is very well, but only Edge.
When I select "Only WCDMA", it shows full coverage, but doesn't connect. I can't even start a call.
I found out, that non-China Telecom phones cannot connect to the network (only 2G).
Also China Telecom phones may not connect to other networks.
So now I guess if i root my phone, and install a china telecom baseband, it will work? Or does it have a different radio?
I'd really be happy to get answers. I can buy a card from china unicom, it's not a matter of the money. But it's the technical fun
Thanks in advance,
David.

There's nothing that changing the baseband will do. The issue is the carrier / sim.
Using another carrier or asking the current one to allow your phone is all you can do.
By the way, you posted this in the wrong section

Somehow, that's not logical for me (I paid, the sim is brandnew). Why should they lock me out?
So I will try a chinese phone with my card, or my phone with another China Telecom Card, that works with 3G.
Thanks for your reply. What would the correct section be?
Thanks,
David.

You may have the wrong modem or CSC for best reception .
But i recall that its a different network band in China from China posts on the forums .

Thank you.
I wanted to switch to China Unicom, which works with Europe mobile phones. But it's much more expensive and i don't need 3G.
As i have to send my handset for repair, I don't want to risk warranty for 3g.

You don't need to modify the phone to use Unicom. It will work as is.

Hello,
I thought about modifying for China Telecom.
I know bought a sim card from China Unicom which allows to get up to 2.5 gb and only pay what I need, starting with 10 RMB for 70RMB to 100 for 2.5GB, which is really nice for me.
I can also use HSDPA now and reach up to 900 kbyte/s.
David.

Just so you know, only China Unicom really offers 3G. China Mobile 3G is only for their branded phones and China Telecom markets 3G that is not really 3G. I use China Mobile, but if I needed 3G I would switch to Unicom.

[Q] Bell Galaxy Note - 2100 mhz?

Hi all
I'm travelling to South Korea next week and I plan to pick a local prepaid sim card. I know Korean carriers use 2100 Mhz spectrum (except LG U+ a CDMA carrier) and when I checked to see if my note supports 2100 spectrum, I found out that it says WCDMA IMT 2000 [Refer to the attached image]
What do you mean by WCDMA IMT 2000? I know what a WCDMA is but if my phone supports 2100 mhz it should say WCDMA 2100, no? or is this another way of saying 2100?
Thanks in advance!
http://www.gsmarena.com/samsung_galaxy_note_i717-4374.php
Look at the bands supported in the general section. The note supports the 2100mhz HSDPA and 2100 mhz lte bands.
Oh dear. IMT 2000 means International Mobile Telecommunications-2000, you might know it as 3G simply Nothing to do with frequencies but I can how confusing this can be when the IMT band http://en.wikipedia.org/wiki/UMTS_frequency_bands itself is said to be 2100MHz and yes, two Korean networks http://en.wikipedia.org/wiki/List_of_UMTS_networks operate on this band.
Im curious to see if it works in Korea or not. Im guessing you have your note carrier unlocked already. Please post results when you get to Korea please. Thanks.

@bean1975
Ya i was really confused I was expecting to see WCDMA 2100 not IMT2000 lol
@chunsaa
Ya I will let you know when I'm there
If your galaxy note is an unlocked i717, phone call and sms works with korean carrier.
However, if you want to use a data plan, you need to set up APN.
bon voyage!

Works great on KT!
Oh thats great to hear!! Thanks for the reply! Can I ask where you unlocked your phone and did you have to change any settings or anything or was it just straight plug and play for the sim card? And i m guessing you are getting data there as well?

I did it through cellunlocker dot net
I never had to changed anything on the phone it worked right away! and ya I'm getting data but be careful not to use a lot since prepaid could be quite expensive in Korea lol
You are awesome! Thank you so much!!! Enjoy your stay there

KT is best and you will get 3g/4g in the areas where they have 2100 band coverage. In older/non-urban areas they use 900 band and our phone (not talking about N7000) doesn't have that frequency. You will drop to EDGE or lower. You can still use data there but it will be sllooowww.

how were you able to get a sim card in south korea? when i went to seoul in january i went to every cell shop and they all told me no and one of the places was telling i had to rent a phone, and there would be just voice no data. i'm pretty sure i went ti KT as well all the places just telling me no in korean. is there a special way to ask for a sim card there or something?
There are stores that deal with prepaid stuff from what I experienced. The small shops don't deal with them meaning you cannot even recharge your balance even if it is the same comapany. You have to walk into a bigger store and ask them there. Just ask them for a prepaid usim card. Alot easier to communicate if you could speak the language.

Have you been to Itaewon? At least, people there will say no in English if they have to. LOL. I believee you can get prepaid phone or sim easily in Itaewon.
You can get anything there and you don't have to speak Korean to get it. Friendly is the key that opens all the doors. 50 times there at least.
Thanks for all the help, hopefully the next time i go to korea i will not have the same issue getting a sim card.
much appreciated

[Q] International (netherlands) - foreign SIM and no data connection

Hi,
I bought the DNA without a plan in America (not in a actual verizon store, but in a other verizon retailer).
In the Netherlands I put in a Dutch SIMcard from Vodafone (Dutch provider).
After installing the SIM and entering the APN settings of Vodafone the Data connection is not working.
I can call with my phone, but after trying the data connection it attemps to cennect a few times but then it says "connection lost".
I triple checked the APN settings and tried playing with some of the settings, but nothing worked.
I went to the Vodafone store and they said the settings were correct and could not help.
They recommended that i should root the phone and install a european/dutch android version.
Because in the netherlands we do not have 4G yet and this is not an option in european android versions.
They said this might cause the problem.
Does anyone have any ideas to solve the problem? (without rooting)
Or can anybody inform me if rooting and installing a different android version might solve the problem? (no rooting experience)
Any help is appriciated, but also other experiences with DNA in Europe (and data connection) are very welcome.
Thanks in advance.
Well considering you can't install a different android version, that won't work.
Only thing I can think of is that your carrier is using a band the DNA doesn't support. What band does your carrier use?

Thanks for your help.
according to http://androidadvices.com/htc-droid-dna-phone/the DNA supports: quad-band GSM/GPRS/EDGE support (850/900/1800/1900 MHz) and quad-band UMTS/HSPA (850/900/1900/2100 MHz)
Vodafone bands are 900, 1800 and 2000 in the Netherlands
So it should work, right?

only if you are in a 900 or area (i guess you mean 2100 and not 2000)
you got me worried, i bought one to use in Colombia in 850/1900, i guess i´ll have to wait until it arrives to check

Yes I meant 2100.
I did hear some in Canada did not have problems so it is possible out side America.
Maybe I am just out of luck, but I hope somebody has the solution for me.
Good luck with your DNA and the Data connection.

According to another forum it just depends on if you have a plan if you have to activate it or not.
If you have a phone without a plan you would not have to activate the phone via Verizon.
If you do have a plan you should activate it.

Yes, but it is also a quadband global phone, this phone can use GSM bands aswell.
at least that is my understanding. since it also works om at&t and canada for example.
Ok installed ukb 1.3.0 Rom and all is working good now! Calls and data I'm happy now
I also changed the networks to gsm/umts only to boost battery since I won't be using lte for now

I'm pretty sure that DNA is CDMA only while Butterfly is GSM.

I'm using Droid DNA in Japan and I have same problem. It also doesn't work in Japan by 3G network.
The carrier (NTT DOCOMO) uses UMTS/2100,1700,800. My country have no GSM and I can't try it yet.
Does DNA work as SIM free just in North American continent?

I tried friend's SIM card and found problems as below.
- carrier: NTT DOCOMO data only SIM (Japan, WCDMA/UMTS, 800/1700/2100)
-- SIM is not recognized ("your sim card does not allow a connection to this network")
- carrier: Softbank (Japan, WCDMA/UMTS, 900/2100)
-- SIM is recognized. Talk works. But no data connection (3G does not work).
I hope to know your APN settings.
Phone is HSDPA 850 / 900 / 1900 / 2100
so that explains why the NTT DOCOMO doesn´t work (maybe not in 2100 coverage?)
you must enter the apn settings of your carrier, in this case softbank, and then select it. have you tried it yet?

What do you mean ukb rom installed?
I looked it up on this forum, but I suppose you need to root the DNA for this right?
What does it change?

Many thanks. My area covers 2100 network. My Nexus One is working in 2100 coverage.
I also inputted apn setting of softbank. But 3G data network did not work.
>Victor Droogh
Yes, UKB 1.3.0 requires root and unlocked bootloader. I already get root and tried it, but problem remains.
I suspect that this problem is not solved even if you get root. I may need to update radio image in Droid DNA.

Can you use the i9300 internationally?

I don't really understand how cell phone providers work, but my friend is in Germany for another year before he comes back to the US.
Would Samsung Galaxy SIII Smartphone (16GB, UK Sim Free Unlocked) work from the amazon.co.uk site for him to use on T-Mobile in Germany, then return to the US and use it on a new contract at Verizon/T-Mobile/Sprint?
It will certainly work in the UK and Germany, with the same modem. The phone will operate on the right frequencies for the USA but I'm not sure you'll get the best out of it, as there will be no specific modem for the i9300 in the USA. Calls & texts will certainly work but data could be slow or none at all.

How to know if a phone is unlocked

I am wanting to buy a phone off amazon.co.uk and i am in ireland. The listing is 'Honor 7 4G UK Dual SIM-Free Smartphone' . So even though it says its sim free it also said 'UK' so does this mean its only usable in uk and not ireland or does in work on any network
Hello,
Welcome to XDA.
Your thread will be moved to your device forum. The experts there may be able to help. Good luck.

It is sim free and it works on any network, limited only with supported frequencies. In Ireland and other EU countries there is no limit.

China mobile PLK-TL00

Hello everybody,
I just got a Honor 7 China Mobile Version (PLK-TL00). Since I'm living in China I tried to use my China Unicom simcard, but I can only use the 2G EDGE network, no 3G or 4G.
Is there any way (e.g. change the rom, unlock bands) to use it with China Unicom?
I also intend to use the phone in Germany/Europe. Will 3G/4G work with any mobile service provider? (I searched google, but I got contradictory answers)
I really like the phone so I hope anyone can provide a feedback to my questions.
Thank you very much!
Thomas
