Hello. Hopefully I started this thread in the right place...
Recently, I moved to China. In the U.S., I was using a Samsung Galaxy S3 (SCH-I535) with Verizon as my carrier. I've rooted the phone, but I've not messed with other things like firmware or custom roms. In China, I have this truly god awful phone with China Telecom as my carrier. The China Telecom SIM card does fit in my old Verizon phone.
So, is it at all possible to redo my U.S. phone in such a way that allows me to use the China Telecom network? I've messed with my phone with the new SIM card, and I've asked Google, but no luck. Any help would be greatly appreciated!

Hey all,
I got a new Samsung G-S4, in which i purchased the LTE International model from Hong Kong last month during my trip to asia. As I am a novice casual user of Android phones, and don't wish to tingle too much with too much advanced modifications, please give me a few start up tips for using this phone in my local Carrier (Rogers) in the Vancouver, BC area.
For once, the main concern is I am not getting LTE data speeds. Please help.
Maybe they can help you here. http://forum.xda-developers.com/showthread.php?p=45245613
Hi guys. I have a Galaxy Grand 2 (G7109), China Telecom model.
It has two SIM card slot, one for CDMA(Slot 1) and the other for GSM(Slot 2) network.
Slot 2 is originally unlocked. But Slot 1 is locked for China Telecom.
Are there any ways to unlock Slot 1 so that I can use other SIM cards for 3G connection or for use abroad?
My phone is rooted. Thanks in advance!

First, thanks for using proper English.
Your operator will unlock the SIM slot if you pay a contract termination fee.
Tried with American operators.

Thank you for your kind reply and the useful info. I will go to the carrier shop and ask if they do the same in my country.
Would there still be other ways to unlock it? I am not going to terminate my contract for the moment but I have a plan to go to another country for a few weeks.

You still have to pay some fee if you purchased the device ON CONTRACT WITH YOUR PHONE LINE (SIM CARD).
Your operator knows better.

I went to the China Telecom shop a few days ago and asked the staff if they can unlock the phone. He said, "The phone is not locked. Some people from other countries told me that they were able to use the phone in their country. Just try using it." So I am here in Japan and tried to use it. But unfortunately it IS locked and Japanese SIM doesn't work. Any solution??

It may be a compatible band range issue.
Operators in Asian countries operate very strange bands (especially China, for political reasons, and Korea).
As I have heard, you cannot travel and bring a smartphone from outside China as the airport cops will confiscate it AND because it won't work.
Operators are the worst liars ever. Rogers, a Canadian operator, repeatedly told me that its Nexus 5 was locked. They lied. Again. And again. Over different shops. But a quick Google search revealed that North American Nexus devices are ALL unlocked. Don't trust your operator.
I'm quite sure it is the bandwidth. Ask your (destination) operator if it operates your device's bands. It also happened with me. Almost tricked by an operator called Vidèotron into buying a SIM card, but it turned out that they don't operate the bands my dad's Note II (Saudi Arabian unit). Checked with other operators and, luckily, some did operate them. Just try different operators.

Thank you for the message. Yes, I also think it is a problem of bandwidth. I guess China Telecom version of Galaxy Grand 2 doesn't work with UMITS 2100MHz, which is a common bandwidth in Japan. I was just able to use it in China, Macau & Hong Kong. It's a good device but useless in Japan...

I'm under the impression that Straight Talk branded phones usually don't work well with other companies' SIM cards... on the flip side, they advertise themselves as being able to bring your own phone to straight talk by having them provide many different types of SIM cards for your unlocked phone. If you find a solution to this, can you post a reply, as I am curious about this as well.
Hi guys, thanks for reading the thread. I know I am fresh here but hear me out.
I actually did have an account but for the life of me cant get back into it, its 2 years since i was on here.
Anyway i bought my sammy (Galaxy Grand Prime SM-G530M, Android 5.2.0) In Colombia after getting 2 phones stolen off me cos of my Gringo`ness.
I bought it "secound hand" as I couldnt afford anything new. Used it with 2 different cellphone providers Claro and Tigo and it worked fine which is why i figure it is not locked to a certain companies simcard, although later on i did have trouble using it with Tigo but it initially did work.
So I brought the phone home with me to New Zealand and stuck an NZ sim in it and it says no service network unavailable. After taking to the shop of the company who`s sim i tried (2Degrees) they said it needed to be network unlocked. To my understanding that means it needs to be unlocked to use on the New Zealand network which involves registering it on the New Zealand cell network data base. Please bear with me ass I know nothing of what i am talking about.
I was quoted $60 which is too much for me as i am a broke traveler. So I was going to use FastGsm to see if i would work but have decided against it as have some concerns about using thier site.
Please let me known if i am totally misguided or if there is a simple solution to this
Thanks
Anyone?
First of all I want to clarify that I am new to this, so I would be very helpful to help me understand this world, I am from Mexico, let's begin.
Good companions I previously had a galaxy s7 model SM-G930T, the device was with the T-mobile company that is from the USA but it was unlocked so I could use it normally in my country, the device had its T-mobile bloatware so that everything normal, well I decided to use samsung pay on that mobile, practically everything worked perfectly, then I sold that phone and bought what I now have that is a galaxy s8 model SM-G950U1 out there I have informed that it is an unlocked mobile from United States with CSC XAA, I find that I can not use samsung pay, when wanting to make a temporary transaction of my card to activate it does not do it, the truth is confusing to me as if I could use sPay with the s7 and now with the s8 No, if both were from the USA, they could help me. :crying:
I am very new in this of Roms of other countries, csc, etc ...
Thanks for your attention.
