Epic 4g in Canada

was wondering if the epic 4g could be used in canada on the bell or rogers(or actually any carrier for that matter)? does sprint sell the cellphone unlocked?
better yet, has an international version(that will work in canada) been released/announced?
from what I know, bell has a CDMA network, but i've never used a phone without a sim card before and i'm honestly not sure how it works.
as a last note, i honestly don't care about the 4g capabilities, 3g is enough for my needs.

I thought all of canada was gsm. I may be mistaken. I know rodgers is. If I an right the answer is no

I have one on virgin (CDMA in manitoba), but am having a heck of a time getting data working...
anyone have any thoughts on this?
I won't discuss how I got it working (Against board rules) but I just wanted to know if anyone know of a fix for my data. I flashed the PRL to a bell PRL, set the APN via an APN app (since the option is blocked out normally).
I also tried the Epic 4g on boost tutorial, but it didn't give me any hex info (presumably because I was taking info from a blackberry)
Thanks if anyone can help

I'm 99.9 percent sure 1xRTT (~153kbit/sec) is the best you'll get in Canada -- if that -- with an American CDMA-only phone. AFAIK, all of Canada's CDMA carriers deployed UMTS instead of EV-DO.
Canada's mobile phones are slightly exotic, because Telus & Bell have legacy CDMA voice, but 3G-GSM for data. I think 2-3 years ago, you could use an imported European 3G gsm phone, but ONLY in 3G UMTS mode -- they couldn't "fall back" to classic TDMA-based GSM, because the network *itself* didn't support it (yet). Official Telus phones literally used CDMA for voice, but UMTS for data. However, I'm pretty sure you can NOW fall back to legacy
GSM, even on Telus (I guess they had to wait until enough customers had GSM phones to repurpose a chunk of 1900 spectrum that was formerly used exclusively for CDMA, or maybe they just roam on Rogers or Bell for GSM voice).

Well I'm on virgin mobile which has EVDO coverage on bell's network here in manitoba. I know this because I ported this phone from an EVDO blackberry (it was a pain in the ass). Also MTS still uses EVDO here as well, but that's going to be short lived as they are in a partnership with Rogers to cover the province with HSPA+. That said there will still be support for legacy devices on their existing towers.

But either way I have no data connection at all. I only show the bars for signal (no other symbols), but I flashed the PRL so it's at least not showing up as roaming anymore lol. I'm also getting the stupid sprint activation message every time I boot, and Error 67 authentication error pops up every once in a while.
Does anyone know what I can do to fix this?

Try reading the Epic on boost threads.

I tried it, but it didn't work, but perhaps I will post my issue and someone will have a solution

did you ever getting working?

Ubergizmo on Nokia Lumia 900 4G/3G/Edge switch

Has anyone else found the following web site with instructions on setting up a 4G/3G/Edge switch on the Web
(Do a search to find the link)
I tired it and was able to get the switch, but I have not been able to try it on 4G(LTE) yet as I do not have LTE reception where I live and only have 3G (the phone says 4G, but I know it is 3G+) but will try it at work tomorrow where I can actually get LTE.
But one thing I noticed is that I cannot get EDGE service where I live. I heard that AT&T wanted to get rid of 2G (EDGE). Have they done that already?

Im not sure what you mean about trying it on 4G... the only choices are 4G (LTE) 3G or edge so you get one of the 3.
In my LTE market when I choose 4G I get LTE.

On AT&T, there are 4 types of data. 2G/EDGE, 3G, "4G"/3G+/HSPA+ and LTE.
We all know about 2g and 3g, but many people like you don't know about the difference between "4g" and LTE.
This whole thing was started by T-Mobile, because this was the early days of LTE, and Sprint was advertising it's WiMax network as 4G, T-Mobile decided to use a technology called HSPA+ and brand it as 4G. Initially, AT&T scolded T-Mobile for this move, but as soon as it was decided HSPA+ could be considered 4G, AT&T rapidly built up a network of this, almost as large as their 3G network.
HSPA+ is basically a faster version of 3G, hence why it's often called 3G+. However, AT&T tries to advertise it as 4G so they can boast they have the largest 4G network, even though Verizon leads the charge with the most LTE sites. HSPA+ is a bit faster than 3G, but doesn't hold a candle to LTE. However, it does have it advantages, such as being compatible on the iPhone 4S, and unlike Verizon, on AT&T, if you loose LTE coverage, you can fall back on HSPA+, where as on Verizon you fall back on their CDMA network (Which is still slower than AT&T's GSM network).
So over all it's good and leads to faster overall experience, unless of course you're in LTE coverage 24/7, then it doesn't matter that much. My (and others) only problem with this is AT&T branding it as 4G, which tricks consumers.

These days, both AT&T and T-Mobile branded devices display "4G" for *any* UMTS connectivity, instead of 3G/H.
It's lame.

My 900 has this switch in the settings without the need for any hacks

you hit #data# and then hit the ... button at the bottom and set up the toggle between speeds. Then restart the device, go under settings>cellular> select data speed.
With this device's data speed selection, 2G= edge, 3g= HSPA+/UTMS, 4G= LTE. Eventhough ATT modified the registry so that UTMS shows 4G at the top of the device, when you select 3G in the speed selection, you are only making the phone connect to HSPA+/UTMS

Hey, they stole my article that I originally posted on Mobility Digest. (www.mobilitydigest.com). They even took my screen shot. I purposely took that shot when my phone was showing "G". Oh well. Btw, it does work.

[Q] at&t 4g on unlocked tmobile galaxy s3??

I have a unlocked t mobile galaxy s3 I'm using on at&t network and I only get 3g but my download speeds are 4 to 5 mb. Which is pretty decent but I was wondering if there was a way to get AT&T 4g? Maybe it's my apn setting issue? Any tips.....

What data plan are you on (medianet/dumb phone, fauxG, LTE)? I've rarely had issues with my unlocked phones having the wrong APN on AT&T, but here are the APNs: medianet is wap.cingular, 4G/HSPA+ is phone, and 4G LTE is pta.
That's about what I get on medianet. I've got as high as 8Mbps on pta but it varies and it's never been consistent for me. 3-5Mbps is normal for my HSPA+ in my area (Olympia, WA). I get about the same speeds in southern CA and tended to get better speeds by 1-2Mbps in Austin, TX.
If you're asking if it's possible to get LTE on the T999, I have no idea. ;P The MSM8960 (S4 SoC in both phones) does support it natively but I don't know if it's possible to enable the LTE modem in software. You could try flashing an AT&T modem but I doubt it's that simple.

Ok maybe I'm wrong but isn't the t-mobile galaxy s3 the only one that didn't come lte equipped because t-mobile uses hspa+?

Hey I have a question regarding this topic and the quote above. You listed the Apn's with its respective data plan:
1. wap.cingular = non-smartphone (i'll refrain myself from calling it a dumb phone plan lol).
2. Phone = 4G/H+
3. LTE = PTA
So I've just switched over from IPhone 4s > HTC One X > to now the Samsung Galaxy S3 (International unlocked version).
When I switched sims from iphone to one x, my data wouldnt work so they told me to get an LTE sim and give them the imei # of the ONE x. So i did that and everything was fine. They updated my account and i was receiving LTE on the phone with no issues.
NOW, with my galaxy, i just stuck the LTE sim in the phone and the phone defaulted to the cingular 410 apn. This is same as wap.cingular.
So here are my questions:
1. Would it be beneficial (from a performance/data speed standpoint) for me to call AT&T and tell them I'm back to a NON-LTE phone and have them change my account to a non-LTE account? And go through the process of changing my imei # in their system again also?
2. Since I'm actually on a smartphone unlimited (i did not take advantage of the $10/mo medianet) should I change my APN settings to "PHONE" and not use what the S3 defaulted me to?
3. Whats the actual difference in using wap vs phone APN's... I know the settings themselves are different, but anybody know the technical differences?
Thanks so much in advance!

T-mobile galaxy S3 on ATT 4G network
Hello can anyone post pics of the Galaxy S3 (T999) the t mobile version on ATT 3g or 4g networks. I am thinking about buying it but wanna be sure that it works before i spend the big bucks

This guy confirmed it works:
http://forum.xda-developers.com/showpost.php?p=27984139&postcount=28
Anyone else have such luck?

I'm having this exact problem. I have an unlocked T Mobile S3 that I want to use on the AT&T network. Phone, text and VM work fine although AT&T hasn't figured out how to give me data service in any form. They're all stumped by this.
What I really need help with is coaching AT&T through the process.

Unlocked AT&T S3 I747 for MetroPCS/TMobile

Has anyone here bought an unlocked AT&T S3 to use on the MetroPCS/Tmobile network? If so has there been any issues? shorter battery life, bad connectivity?
I am debating getting the S3 unlocked or HTC One S. I would prefer the HTC One S but it doesn't have microSD slot

I have a SGH T999 Lte at&t branded unlocked and use on TMobile with the T999L lte rom with no ill effects.

Is that the same model as my phone? So it would be advisable, after I got the S3 to flash it with a MetroPCS ROM after activation by Metro?
I thought there would be no need of a flash if I got an unlocked phone.

You will have issues with 3G HSPA+ on 1700mhz, but 2G EDGE & 4G LTE will work just fine. If you live in a large metro area with a lot of LTE coverage it will be fine. I just went through this with my wife's phone, she had to have the Red one (AT&T specific).

There is no need to flash anything, just unlock it and add/edit the APN for TMo.

Sweet thanks! Both areas that I frequent have 4G and LTE coverage. My only concern is when I'm driving long distances which I often do, being in college and losing 2G signal in the middle of no where. So far with my Metro phones, I haven't seen anywhere I had 3G coverage. its always 2G and 4G/LTE

Good, that is exactly what we are seeing as well. Mostly LTE coverage with EDGE to fallback on. Most all Metro areas and major highways/interstates will have good coverage. Funny enough we live in the middle of nowhere, but there is a major highway nearby so we get LTE coverage.
On a side note, US carriers marketed HSPA as 3G and HSPA+ as 4g, but both are technically 3G. True 4G is LTE. I am not sure if Metro ever had HSPA service, I think that they were just CDMA then later added LTE and have been migrated to TMo's GSM/HSPA network which now uses Metro's LTE as well. Only the newer GSM Based phones would connect to HSPA.

Define Slow data please. Post Speed test results.

normally around 0.15mbs but sometimes it works great and I get around 15.00mbs

Given this is not an LTE device, that sounds about right. Weather, tower congestion do affect results.

The I747 is an LTE device, my wife's (running on TMo) works just fine on LTE, just not HSPA+ 1700MHz. I'll run speed test if people would like.

Unlocked att siii will not access metro/t-mobile data
Can someone verify for me what the correct apn settings are? Should there be a network operator? And since I think the apn is finally right, do you have any more suggestions? Also, do you know if this is CDMA or GSM?

can I ask why people want to buy an ATT phone to use on a Tmobile carrier? On the S4 and Note versions, people buy Tmobile phones and use them on ATT, myself included. This is because of the bootloader, and the Tmobile phones cover ATT LTE channels while not the opposite.

Wasn't planned
I didn't intentionally set out to buy an AT&T phone, I was just looking to upgrade and this was the best deal. Or at least it looked to be on the surface. Do I just need to forget it and try to sell it?

If you are in an area recently upgraded by T-Mobile, the I747 will work just fine. However, if you are in an are not upgraded with LTE, etc, it's waay more trouble than its worth. The above post about not getting HSPA+21/42 is worth considering too though.
T-Mobile and AT&T are both GSM networks btw.

I am actually on Metro P.S, but they are on the T-mobile network now in Atlanta, Ga where I live. We do run 4glte,but so far the fastest mine will connect to shows "E" on my phone, edge maybe? One of the many I've spoken with at metro said E is 3g. One of their repair techs said I needed a different SIM card because I had a CDMA phone but when I got to the store that had one he said it was a GSM phone. It's already about been more trouble than it is worth, but as much effort as I've put into it already, I'd like to resolve it.

Request. Need EFS backup of Singapore Optimus G E975

Hi guys I need an EFS back up of any Singapore Optimus G. I'm using Singtel. My sim card works on other phones (can get 3G and 4G) but my phone can't.
The mobile data only shows a 'G' not 3G or 4G. My mobile network type shows 'GPRS'.
I use to have 3G and 4G LTE. Now I'm limited to 2G speeds.
