Buying and unlocking infuse 4g on an Indian carrier

So as the title implies, im planning on purchasing the At &t carrier locked infuse 4g from the american EBAY site and wish to use it on an indian carrier.
Before i make the purchase, could somebody tell me about the risks involved and the success rate of the procedure mentioned in this forum?
Dont want the thing bricking on me or anything.....=x

Wrong Forum buddy!
as for unlocking it. it will be unlocked and work on any network, it would be up to you to see if you will be picking up 3G or Edge speeds.

Ah sorry, ill be moving this to the Q & A section.
Btw do i absolutely NEED a sim card pre installed inside the phone to unlock?
And how safe is the unlock procedure?
Like is there a chance that i may not get the right code or something?

I suppose on the rare chance it could be possible to get the wrong code, but honestly if you follow the instructions that are posted here; you shouldn't have a problem. I don't believe a sim card is required to get the code since you don't need one in the phone to mess around with it when you turn it on. I could be slightly wrong with that though, but I'm almost 100% certain that won't be necessary.
Make sure you post stuff in the correct forum in the future though.

There is minor chance if you use batch file unlock but not with manually finding a code. Make sure not to enter wrong unlock code entered more then like 5 times.
You will be able to use 3g on airtel gujarat and bsnl networks.
Infuse is dual band phone and not quad band which is standard now more or less and i wonder why samsung did that. So long story short it might not work on some networks india even for voice. Your best bet is galaxy series gsm phones.

Infuse is quad-band GSM which is standard. Quad-band UMTS is almost unheard of... Triband UMTS is the standard (two carrier-specific USA bands + the international UMTS2100 band)

Infuse is 850,1900 gsm and dual band umts not quad band gsm. See page 171 of manual.
Quad band that's what i thought earlier but has to make sure before selling on ebay and realized i was wrong. Many cellphone website list it as quad band gsm which is incorrect.

That's only FCC-required safety information for operation in the US. In the US, it will only operate on those bands so they only publish SAR information that applies to the USA.
In addition to those bands, it supports others. Complete list is:
GSM850/900/1800/1900, UMTS850/1900/2100

i am using unlocked infuse in india.... unlocked using method on this site... no issues...

I went to India on vacation last month... used my Infuse on three networks -- BSNL, Airtel, and T24. Worked on all three. Airtel was the best using 850 Band. T24 used 2100 band. Don't remember what band of BSNL it used.

Great. As I was selling on eBay, default specs eBay adds from cnet says dual band and manual also says so, I was going by that.
Useful info and real world experience from form member means I can take it with me in upcoming visit to homeland.

diablo009 - could you tell me if it allowed you to select the network operator manually OR how it brhaved if you ever went out of the coverage area? Did it select another network automatically?

Samsung Infuse 4G works in India!
Hi, Infuse works very nicely in India mobile networks, at least it works fine with Vodafone. This phone is sure an amazing phone I have seen so far till date!
It is available with ATT for around 70-100 US$ depending on season under 2 years contract. You have to pay around 320 US$ if you want to break the contract. Every month the minimum payment towards monthly usage charge is around 70US$ (features are mandatory, this is the lowest minimal). As you use and pay, every month the contract break amount will be reduced by US$ 10. Still this is worth for the mobile. Again you will be having a legal phone too.
It is a Quad band mobile. You need unlocking code to unlock the phone, the procedures listed for rooting and unlocking sometime works only with certain SIM available in US but the minute you try with a SIM from India the mobile will again ask for Unlock code. The maximum retries is 10 times (again this may differ with the firmware in your mobile).
This phone has an excellent screen quality, very good camera, 1.2 GHz processor, 2 GB for application, 14 GB internal memory, 2 GB SD Card (upgradeable to 32 GB), HDMI out, very slim and light, has scratch proof gorilla glass too.
Apt screen size, very good accessories (Desktop dock with its nice app, 3rd party 3400 mAH high capacity battery)
Install Nemus Launcher / Launcher Pro... it will make the phone pleasant using it!
Note: Upgrade to Gingerbread is not available till now and there is no clue on whether it will be available in future! this phone has an issue in connecting with Kies software from samsung though the menu in the phone for connectivity has it as one of the options of connectivity.

International unlocked in North America?

Let's say I buy an international One X. I unlock it myself. Would it accept a sim card that is for the XL and still give someone 3G?
[Not that I'm actually doing this, just curious ]
Sent from my One X using xda app-developers app

It should. Assuming the sim card slot fits the same size sim card, if not you could get an adapter if it needs to be bigger. It should work on any gsm network after unlocked

Assume you are talking about the quad core Tegra3 One X, which most people call the "international" version. Although the dual core LTE Snapdragon version has been released in so many countries in various parts of the world at this point, calling the other (quad core) version "international" is somewhat moot and confusing.
Whether you get 3G depends on what carrier you are talking about. The quad core One X has the proper 3G bands to work on AT&T (850 and 1900 MHz). But it lacks the AWS (1700/2100MHz) band that for the most part is needed to get 3G on T-Mobile (although they have been adding 1900 MHz in some cities). I know you have the AT&T logo as your carrier. But you seem to be asking a generalized/hypothetical question, so I'm giving you the most correct answer in respect to that type of question.
In general, if a smartphone has the proper 3G band compatibility with your carrier, as long as the phone is SIM-unlocked, it will work on 3G. You will likely also need to manually enter your carrier's APN info into the phone settings.

6045i after using panasonic

I'm shipping this phone to Europe tomorrow,someone is taking it for me. I used the panasonic software and at first when phone booted I saw it shows 2 sims, the I model has one sim. So does that mean it flashed the European radio? I don't care at all for US bands since this will be used in Europe - Poland. I also don't think the i model has LTE bands for Europe unless it has with proper radio?
can anyone help me out? would apperciate it a lot!
thank you.

The second sim is due to Eluga Switch being a dual sim model, once I flashed MM to the phone it went back to single sim, ironically though even out of box the 6045I shows two IMEI #s but only one is active, on Eluga even though it showed two sims my SDCard was still recognized (on dual sim models the SD slot is sim 2, so you should be fine. I believe all the Custom MM roms even need some build prop edits to enable second sim after installation. Can you test before shipping or do you live in a different region than whoever is receiving?
Who will be the service provider in poland??

Eluga supports the following bands, so if his provider in Poland supports these he should be good, you mentioned you were using Aleks Fly OS, so I don't think modem or fsg changed from eluga
HSDPA bands 850 / 900 / 1900 / 2100
LTE band 1(2100), 3(1800), 7(2600), 8(900), 20(800)

They are only soft-disabled by the phone manufacturer to comply with local regulatory bodies like the FCC.
Snapdragon chips support a lot of bands out of the box. The radio can possibly be modified to unlock all of them.
I've seen some Cyanogenmod ROMs for other SD phones w/ a menu for turning radios on & off by the region you're in.
It's also probably good for battery life to not be scanning on bands you don't need.

The phone got delivered today and says no sim card found. They sent me bunch of pictures and everything seems to be OK.
The sim card is active from a tablet on prepaid plan with Orange.
Any ideas what to try?

Again international model don't have all the bands for USA carriers

Hey there,
Not that I am 100% sure, but I've called this statement into question in another thread, I'll repost here.
In one of the threads here on XDA, another member suggested he ordered the intl. model and it didnt support the right bands for the USA. Leading me to think there were multiple models.
I'm starting to think there isn't, here is why.
1. Michael Fisher (I think he's in Canada) imported a TW market phone for his early review. It appears to have LTE in the film, and he doesnt mention anything about incompatibilities.
https://www.youtube.com/watch?v=WIWbn8ecKwA
2. Jeff Springer (I think he's in the USA) imported a HK market phone, it also appears to have LTE - https://www.youtube.com/watch?v=fclOYUyfxnE&t=522s
I believe the belief that the intl. model doesnt support USA bands (2/4, etc) comes from the practice (poor practice, admittedly) for HTC's Taiwanese website to only declare the bands that it perceives are relevant to Taiwanese users. The HK website suggests the same as taiwan = FDD: B1/B3/B5/B7/B8/B20/B28 TDD: B38/B39/B40/B41
The UK / India / USA / AU sites all state - FDD: Bands B1/B2/B3/B4/B5/B7/B8/B12/B17/B20/B28TDD: Bands B38/B39/B40/B41
With USA & AU not stating support for dual sim, but HK, TW, India, UK do.
I believe there is only one model (with multiple software variations), and the information published being variable.
I now know there are at least 2 model numbers. U-1u (Taiwan and HK confirmed to use this model, dual sim), and U-1h (single sim, AU and UK confirmed). But given the info above (michael fisher and Jeff Springer both importing the U-1u, and seemingly can connect to north american lte, seems to suggest that the band support for U-1u is wider than the official website specs)

HTC U Ultra - got from imobilephonex
Hey there
I got from New HTC U Ultra form imobilephonex
Really good price & brilliant phone :good:

Here is the breakdown officially from HTC's website. The dual band international version is missing 2, 4, 12 and 17. 17 being the most important one.

So get this I wake up to a text from FedEx saying I have a package coming I didn't order anything else so it's out for delivery! I checked the HTC site and it still says it hasn't been shipped and no tracking number!

It's cheaper on eBay (649) and it's from a US based seller instead of having it shipped from Asia. What is holding me back from this phone is the horrific resale value of HTC and LG products. Once the S8 is announced/released this HTC U Ultra can be purchased for an insane amount less than full retail. Apple and Samsung phones hold their value well even used but unfortunately phones like this are not worth buying new for full retail IMO.

Having an LTE sign does not mean it supports the entire range of the network.

Dual SIM

Anyone know if N20 Ultra will have dual SIM in States? I've searched but couldn't find anything solid on it.

ANy update fellas? Are they gonna release OTA to add eSIM functionality? I am regretting buying this 1300 bucks toy now.

I want to know this too, would pull the trigger right now but can't find it. Official site says there are single and dual sim models, but when you go to checkout doesn't say what you're getting!
https://www.samsung.com/global/galaxy/galaxy-note20/specs/
Just chatted with support, FWIW, he said only the Global version has dual-sim, not the US version.

Well that's a bummer.. I guess it's going on swappa or offerup, still making money.

So the USA model won’t even be dual sim EG one physical sim and one e-sim? [emoji23]

Nope, yet Apple has had it for two years!

Dual sim= Sim+ eSim
Exynos

just like the s20 ultra it isnt clear at all. there does seem to exist a 'B' model and an 'F' model, some are dual sim, some are LTE only. its hard to find exactly the right one. In the Note 10 the 'F' model didnt have band 30. But on the LTE only s20 (no 5G) there is band 30. But on the 5G model there isnt band 30. Frustrating if you use AT&T
I think the dual sim model of the Note 20 ultra is sm-n986b. its not clear if its dual sim or sim plus e-sim.
The US models are historically NOT dual sim on nOte 10 and s20.

In Europe is dual sim = sim + sim or you can use sim + esim + SD card on ultra

If you look at the USA web site...

That link is for "global" version and it says ESIM support is dependent on country/carrier. Samsung has disabled ESIM specifically for US for some odd reason. They promised S20 will have ESIM with a software update but that did not happen as of yet, we can only hope their $1500 flagship N20 Ultra supports this but as of now there is no mention of it.

Don't hold your breath!

Has anyone used one of the international Dual-SIM unlocked models recently? I'm guessing they still don't have the ability to do VOLTE and Wifi Calling because they don't have the US CSCs available. I have the US unlocked Note 10+ and appreciate how smooth the carrier swap process is, but like everyone else I'd prefer to just leave a couple of SIMs in at the same time.

It depends on the carrier, but you will get WiFi calling and VoLTE on US Tmobile if using Exynos dual sim model. It lacks the important bands though like band 66, band 71 and some 5G bands

From what Ive seen and reading - no Dual Sim in North America ( same like S20 ) -which means Physical + Esim, having just Esim means phone w/o a physical sim and thats it, but not work in conjuction
Users experience for S20

It acts like the regular Snapdragon version will support Dual Sim???? I won't be able to test it out until Monday so curious if anyone else has tried.

I have an ATT SD variant that lists 2 IMEIs on the box, however, it appears the eSim functionality has been disabled. there's another thread on the eSim where this is being discussed as well.
