Using the Samsung Epic 4G internationally (india)

Hello,
I have the Samsung Epic 4G (SPH-D700), from Sprint.
How i can use my new phone internationally ?
what will unlocking a the phone will achieve for me?
Once unlocked, can I add CDMA service from international operators/carriers, such as India ?
Also Is an unlocked phone the equivalent/identical to a OMH model ?
thanks
Rudy
Note: OMH (Open Market Handsets) is an industry initiative led by the CDMA Development Group (CDG) to increase device variety and offer new channels and distribution options within the CDMA ecosystem.

I don't think you even need root access to use CDMA Workshop and do things that are illegal, at least in the states - to get the phone working on another network. Given - each phone is different so there are no straight forward write ups for most carriers on how to get MMS,SMS,Phone, and Data working on the specific carriers.

I am new to all this unlocking process
Are you saying that, CDMA Workshop will allow my handset to be added to other carrier/operator service ?

You want to use it in India right call Tata Indicom and ask them they are a CDMA carrier in India that can reprogram your phone while your their. They should be able to answer all your questions.

i woudl just buy a cheap world phone off ebay and use prepaid sim cards. thats why I kept my blackberry. either that or you could pay sprints rediculous charges for international calls. I don't think you will have an easy time getting another company to reprogram the phone for you.

western europe for 5 weeks...international sim cards?

so after doing exhaustive research on the subject I was not able to find a definitive thread or answer on the subject of using international sim cards on an unlocked g2. I'm hoping someone here at xda has experience with this and is able to give me advice.
I'm going to be backpacking europe for 5 weeks and want to bring my g2 to use as a computer (while connected to wifi) and making rare calls (just to check in with people at home), htc's website says this phone is quad band and umts http://www.htc.com/us/products/t-mobile-g2#tech-specs but I've never traveled so I'm not sure what to make of it.
any help would be very appreciated!!
edit: called tmobile and they were no help at all, the rep was reading off a script that didnt have much info. looking for personal experience please!

Hi,
G2/Desire Z as you rightly point out will be able to deal with mobile networks in Europe.
The problem you face is that a Sim from county 1 will work Ok in that country but will attract data roaming charges in all other european countries.
That's unless you negotiate something with the operator prior to your purchase regarding both mobile data and call roaming charges.
Chances are you will get a better deal from maybe Germany or perhaps france. Check them both on the web and also check the uk operators and see where you get..
Des. . .

Essential: WHEN will you be going? Because TMO Germany is about to bring up an Europe-wide (or at least Western Europe) roaming-charges-free card. I'll look it up and answer asap. Hold on.
EDIT: TMO Travel & Surf does not include (or not even feature? Not clear from the Article I read) calls. Sorry. PLUS the Prices seem not really good to me. I haven't found anything you're looking for in Germany yet. Could do with it as well. Greez, mwrsa

I will be travelling march-april. I guess what my question is, once they send me my unlock code and I unlock my phone to use the international sim, I will not be tied at all to tmobile or their roaming charges unless I put my original sim card back in the phone is that correct?
does anyone have any recommendations what carriers are the best? I'll be going to UK, France, Netherlands, Germany, Czech, and Spain

well I can't speak for europe I'm currently out of my home country with my DZ, I unlocked it with gfree, which I would reccomend. also its definetly cheaper to use a local simcard from where every you are travelling, there's no getting around roaming charges and insane rates if your going international. I personally picked up a free ATT card here where I am and paid 20 bucks for 100mb of data, since calling and texting is still expensive I communicate through "whatsapp" with my wife and family . it worrks on data or wifi, let's u send and receive pics and videos and uses a surprisingly tiny amount of data to do so. id honestly reccomend this route so long as your family has a whatsapp compatible device, currently its available for blackberry,droid,and iphone.
sorry I can't be more help but with "real life" experience I found this to be the best route. if u need voice, its still cheaper to pickup a 20dollar long distance calling card and use the hotel phones. or skype app when your on wifi.
hope it helps a bit! and have a safe trip!

Problem is, that at least with German SIM-Cards, you need an adress here in germany ti register the card to your name. Austria and GB have "3" as a network operator. AFAIK they have a sim-card with no roaming fees where "3" is available as a network.

Hi,
I'll be going through europe this summer. The suggestion of getting a local PAYG sim is good, on the face of it. Unless you are going to be in that country for just a few days (as I will be) then, perhaps, it is more aggravation to get the sims than pay roaming.
A sim from Germany - if it was to include some country roaming - from either O2 or T-Mobile or even Voda - may be an answer.
Very much depends on how long you will be in each country I guess.
A week+ stay in each country, and a sim from each country when you get there could week prove to be your way forward.

HI,
This is worth a read. Gives you some idea as to prices and amounts:
Roaming Data Charges - UK Accounts...
Des. . .

As far as band compatibility, the important thing is that your phone is compatible with the bands used in Europe. Looks like Europe uses the 900 and 1800 MHz GSM bands just about everywhere for voice, and UMTS 2100 for 3G. The G2 has GSM 850, 900, 1800, 1900; and UMTS 1700/2100, 2100. So you're good to go as far as the hardware compatibility.

International sim card
Hello!
Have you ever heard about international sim cards? In my opinion is the best solution to save on roaming charges!
Personally I use WorldSIm, they have both a UK and US number in the same sim card and have free incoming calls in over 90 countries.
There are more like this in the market but I can only speak about what I already now and I'm very happy with.
Hope it helps!

Using on At&t?

I'd like to buy this and use on AT&T.
What hoops do I have to jump through to make this happen?
The frequencies are supported (don't care about LTE).
For example if I buy unsubsidized on Amazon, do I have to call Verizon up and get a code from them that will let me use it on AT&T and other GSM carriers?

It's locked for US GSM bands, as far as I know. P3Droid has said that they're working on getting it unlocked. I'm sure we'll hear about it when it happens.

I bought my RAZR M at Amazon (Verizon, without contract) and i use it in Germany with O2 Provider.
No Problem, nothing needed. It´s not locked.

Correctamundo (sp). In further searching it looks like they block the MNC for at&t and t-mobile inside the radio firmware NV settings. Also there is a pesky "unknown sim" or something that pops up every bootup.

Working in India/Asia ?
Hi,
I'm planning to buy one in my visit to US next week. I intend to use it with GSM India.
Has anyone used the phone with GSM provider in India or other asian countries? I was told that GSM capabilities works only in european countries , so wanted to make sure of it before I buy it.
Thanks

Just check and make sure the bands that your network uses are supported. It supports all the standard GSM bands, so I don't see why it wouldn't work.

[Q] Possible to Unlock?

Hi I wanted to buy this pone from amazon, but the thing is that I would buy the sprint versión with no contract and I don't live in the US, so my question is, can I unlock this pone to use it with any other company? like Movistar? I read that the pone was GSM so I thought it would be posible, however I won't take the risk of paying 590 dollars for a pone that I can't use, thanks

What do you mean if I dont know dont tell? What does that supposed to mean?
I KNOW my Cellular Networks!
Sprint is a CDMA Network!
The ONLY part about sprint that is NOT CDMA is LTE which the sim card slot is LOCKED to sprint.
They MIGHT be a fix but right now there is NOT. Some of the older phones like the Moto Photon its not LTE but its a world phone and people could flash a few things and make it work, But only EDGE in the USA anyway.
But as of right now and problay for a while its NOT going to work.

Modem patch is not even possible with this phone right now... The phones are ONLY meant to run on GSM for LTE data and NOTHING ELSE

I expect Sprint will provide a method soon to unlock the GSM and UMTS functions in the phone to be able to use it internationally. However, I don't expect the GSM and UMTS functions to operate inside the US. Sprint has always disabld them on GSM capable Android and iOS devices it sells.

I don't see why it wouldn't work for you as long as you can get it unlocked.
Sprint is not going to unlock it for you unless you are a long time customer or have the phone with them for 90 days.
hyelton is completely wrong though.. the sim does authenticate lte on sprint but also acts as a gsm sim internationally.
you can also remove the sim and insert any international sim once unlocked providing the carrier uses the correct bands.

You are all kinds of WRONG.
Sprint's GS4 is fully capable of voice and data on international GSM/HSPA+/UMTS 850/900/1900/2100MHz networks. You have to request Sprint to unlock your phone's sim (or find a work around if you're not a Sprint customer), but once unlocked you can pop in any international sim and it will WORK JUST FINE on international GSM networks, they don't have to support LTE. Heck the only thing preventing the SG4 from working on US GSM networks is Sprint locked the Sim from using USofA GSM carrier sim cards.
As long as the OP can get their Sprint SG4 sim unlocked, they can pop in their international sim and use the GSM in their country NO PROBLEM like any other GSM phone.
SO ONCE AGAIN, Sprint's SG4 has a fully functioning GSM modem that supports international carrier GSM/HSPA+/UMTS 850/900/1900/2100MHz bands!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
You would think someone with almost 2,000 posts and who made a statement like "I KNOW my Cellular Networks!" would know better. Do yourself a huge favor and actually know what you're talking about before you go spouting off again, because you really made yourself look like an ignorant fool.

Well YES you can easily use your phone overseas, But it was POSTED in the Sprint Forum which is ONLY in the USA and in which using it does NOT apply in the USA. And to get the phone unlocked I`m not sure if a regular unlocking company would be able to do it someone with a sprint account would and it would be MUCH more trouble than just to pick up a ACTUAL GSM carriers Version of the phone.( I should had just said that to begin with) Its VERY pointless to TRY and want to use the sprint Version when they are SEVERAL OTHER varrients that are GSM they could have got to use.

EXCEPT... the op specifically said they wanted to purchase it from Amazon America to use on their country's GSM network.
Why they want to do that? WHO KNOWS, maybe it might be cheaper doing it this way, but that is what they want to do and despite all your unnecessary wrongful information, the OP can do what they asked as long as they can get the sim unlocked.

I sell on Amazon and Most people wont ship out of the USA on Amazon. Mostly only Candia but Ive tried ordering a lot of things overseas and 90% I cant as they wont ship here

Amazon sells the Sprint for $599 this is probably why. I bought mine at Best Buy and had them price match Amazon for that price.

Looks like everyone here is an expert in this matter but so far haven't seen a single link to reputable sources... OP call sprint international department and get answer straight from the carrier (888) 226-7212
Even IF the phone is capable of being used in GSM bands internationally, you would have to get it unlocked by sprint and they change policies all the time so just call..

I got my phone unlocked for international use. I contacted sprint international services. I was initially told that you have to be activated for at least 90 days before they could unlock the phone but would forward my request to some department. After one day I got a email that my phone has been unlocked.

Yea.... but it ONLY works internationally AND you have to be a sprint customer.
The POINT I have been trying to get across is that people need to understand Sprint is a CDMA carrier and ONLY relies on GSM for LTE. I think what people think is that they are solely a gsm carrier like most of the world is but its NOT

Oppo Find 5 carrier question

Is the Oppo Find 5 able to be used on any carrier? I'm currently on Sprint, but may switch to Verizion near the end of the year when my contract is up. Thanks

no. this phone only works on a GSM carrier
Sprint and Verizon are CDMA. completely incompatible
You can only use Sprint phones on Sprint networks, Verizon phones on Verizon networks (some loopholes about using Verizon phones on Sprint if you manage to flash and override the locks)
this is why I stick with AT&T / t-mobile (both GSM carriers), but they aren't that good either( price or service). there are other gsm carriers (but they typically resell service from att/tmoblie)

That's unfortunate to hear. I was really wanting to try this phone. Thanks for the reply

You can't put a cdma card on Find 5. As for 3G networks, it supported WCDMA (AT&T uses it). But if you buy this in China, you may buy a China Mobile phone! China Mobile uses TD-SCDMA (made by theirselves), other carrier never uses it!

WCDMA/GSM or TD-CDMA/GSM in China
WCDMA/GSM or TD-CDMA/GSM in China
i don't know exactly in other countris.you'd better call the service-line for details.

Unfortunately, you can not use it because Sprint and Verizon are CDMA network operators considering that the Oppo Find 5 is gsm smartphone.
