[Q] S4 SGH-I337 or SGH-I337m? AT&T or Rogers?

Sorry moderators, put this in the wrong section last time! Feel free to delete previous post!
I spend 50% of my time in the US and 50% of my time in Canada and have a contract with both AT&T and with Rogers.
I am going to buy the S4 soon. Should I get the SGH-I337 variant with AT&T or the SGH-I337m variant with Rogers?
In about 14 months, I will be back in Canada (on Rogers) permanently. So far, I am leaning towards the AT&T variant due to greater rom availability, but I am worried about whether the S4 will work on Rogers 3G bands and LTE network.
The reason I am worried is that I am currently using an unlocked Sprint BB Tour 9630 Quadband on Rogers with specs:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 2100
CDMA/EVDO Rev A 800/1900
And the Roger's EDGE network barely functions on that phone (many disconnects).
I am a little unfamiliar with network bands, but can you let me know if the phone's 3G radio and LTE radio are identical across Rogers and AT&T?
I read somewhere that Rogers S4 uses 2600 MHz LTE Band and AT&T uses 700 MHz LTE. Is this true? Or does this phone have both LTE bands built in?
Thank you!

After a quick search, I believe both phones should have identical network capabilities.
So you should be able to get LTE and 4G access on either of the networks using either of the phone variants.
The 'M' after the model number is definitely a Canadian carrier thing and it makes no difference. I have a Galaxy S2 from Virgin/Bell which was sold in Canada as GT-i9100M but it was identical to the international GT-i9100. So much so, that I was able to flash the ROM for the international GT-i9100 on my phone without any modifications or complications.
Hope it helps! Or a more senior member can chime in and correct me!

i would recommend going with the rogers i337m. the only reason that there is more roms for at&t version is that there is a stronger demand for them. but any roms meant for i337 will also work on i337m.

Why would you choose the Rogers version?

if you were thinking about getting the s4 soon i would go with att variant like you said because of the rom availability, but if you were going to wait, let say a few weeks to a month i would just get the i337m because samsung will probably push another update to ruin djrbliss work to unlock the bootloader. just keep checking back to see if any update gets pushed through and youll be good

Ah, the Rogers bootloader is unlocked, but AT&T is locked, correct?

Unlocked boot loader.
Sent from my SGH-I337M using xda app-developers app

Hmmmmm. Thank you all! I may just end up getting the 32gb model from AT&T, since I know the AT&T model has the same radio bands built in for 3G and LTE. I'll just hope for an unlocked bootloader!

AT&T has a locked bootloader, but you can get it in 32GB. However there are works underway to get around the locks.
Rogers has an unlocked bootloader but only comes in 16GB. Unfortunately there are no ways that I know of to get around the lack of internal space and JB does not let you install apps on external SDcards.

Perfect. I'm going to trade my Blackberry Q10 for the AT&T S4 32gb.
Thanks!

WIND mobile (Canada) Galaxy S4 compatibility

Hello everyone,
I am really confused about different versions of Galaxy S4 and their compatibility with Wind mobile in Canada.
As far as I know, there are i9500, i9505 and i377 variants.
I was looking forward to buy the i9505 model but I'm not sure if it is compatible with Wind mobile network. (Right now I am outside of Canada for a while so getting a phone in a duty free shop makes sense.)
Does anyone know if i377 or any other variants of Galaxy S4 is compatible with Wind mobile?
If it matters, right now I have a T999V (galaxy S3) which works fine with Wind's network.
Thanks in advance

The GT-i9500 uses the exynos octa core cpu and isn't available in North America because it doesn't support LTE here.
The GT-i9505 is the international S4 that uses the qualcomm quadcore cpu which is marketed in the USA as i377 (at&t) and i377m (bell/rogers/telus) in Canada. These 2 variants don't support AWS bands out of the box, but users have shown a way to enable that on these phones.
There is also another variant of the i9505 marketed as SGH-M919 for T-Mobile in USA and SGH-M919V for Wind/Videotron in Canada. These support AWS bands out of the box and work perfectly well on all North American providers such as At&t, Rogers, Bell, Virgin Mobile, T-Mobile, etc.
Hope this helps your dilemma!

Thank you for your elaboration.
In other words, if I went and bought an SGS 4 with model number i9505, it wouldn't work on -say- Wind mobile out of the box? Should I strictly go for M919? Or are they all the same i9505 hardware only different radios? This "radio": are we referring to the baseband firmware or the actual circuitry inside the phone itself?
Sorry for asking again but I'm trying to clear up the confusion.
Thank you very much in advance

1) All GT-i9505 variants have the same hardware which includes the radio chip, cpu, ram etc.
2) The software part (modem) that controls the radio module is different in the variants which is why some of the users were able to 'activate' AWS band support on the At&t/Rogers/Bell S4 by flashing the appropriate modem/rom.
3) I believe if you purchase the GT-i9505 it will still work on Wind Mobile and the other carriers. But keep in mind that you may or may not be able to connect to LTE or lose reception in some areas where they only run the network on a respective band.
This is where you have to do your homework. Go to Wind Mobile's website and see what bands they use & then cross reference them with the GT-i9505 supported bands.
After you do that yourself and are fairly confident that the phone should work. I'd suggest that you call up Wind mobile and ask them to ensure if that model will work on Wind completely. Just a heads up, you may not get the most knowledgeable tech on your first try...so you may have to try again.
If you just really want that model from the duty free, just get it! I'm sure one of the more advanced users here will be able to point out what needs to be tweaked for it run flawlessly on whatever network.

Now that clears everything up

bought the GT i9500
I bought the GT i9500 galaxy s4 when I was on vacation outside Canada.
Now I'm back here and cannot connect to wind network.. It always goes on roaming :crying:
Please someone let me know what to do with my phone. Can I sell it to someone using Rogers/Bell/Telus? as my friend has a rogers sim card and its working on my phone
Also would be thankful if someone could tell me what could I do to make wind work on my phone.
I had the simcard cut by the phoneseller when I bought it so I could use it when I come back here. Could that be the problem? I mean, would it work if I bought a new small sim card from Wind?

No it won't work.I
I got a phone UK from 3 network and it didn't work and after lots of research I found that it is missing the AWS mode. Mine also works with Rogers, Telus and Bell but not Wind mobile. The store just cut my cimcar for $5 and did not work.
I was reading that there is a ROM or firmware that should be updated.
good luck and let me know if you fixed it.

Samsung Galaxy S4 on Wind Mobile
Were you able to get this working on WIND Mobile? I am in the same predicament, and need to get this working but it just keeps roaming. Wonder if there is a ROM that can be flashed to support the AWS frequency for WIND.

Convert T-Mo Note 3 to Int'l Note 3 w/ NA compatible LTE?

I don't know if this is the correct forum to post in or not; I'm just trying to get the maximum exposure possible so as to hopefully get the best response or attention:
I know that for the Note II, you could take a T-Mo or AT&T branded device, flash the N7105 (Int'l LTE Note II) firmware, and then flash the AT&T/Rogers/T-Mo specific modem.bin, and you'd essentially have an International LTE Note II working in North America. This is what I currently have.
So, what I want to know is, can this be done for the Note 3 as well? I imagine you'd want to use the T-Mo Note 3 for its unlocked bootloader. Supposedly it has been confirmed that the T-Mo and AT&T Note 3 are identical as far as hardware is concerned (despite conflicting advertisements).
Has anybody thought of this yet?

[Q] G900A or G900T for ATT LTE?

I am ATT customer. I am considering buying the Samsung S5 and am trying to decide between G900A and G900T.
I understand G900A is meant for ATT and G900T is meant for T mobile.
I read also that G900A does not have LTE 900 band.
Can someone explain to me, if I am better off with G900T even though I am on AT&T - because I travel internationally.
For example, in the case of Note 3, I was told that N900T was better than N900A, even though I am on ATT and the N900T - note 3 Tmobile version works just fine on ATT.
I am wondering if the same applies for G900a also?
My primary use for the, rooted, unlocked G900T is on AT&T network... 90% of the time. 10% of the time for international travel.
Is it true that G900T is better than G900A for my purpose - something about G900T having an extra LTE brand and that it is easier to unlock than G900A?

I dont think i understand fully what youre trying to say. Are you trying to decide which phone is better for international use?

i ordered the samsung s5 N900T.
I am not certain but I thought I read that the boot loader is locked on n900A -ATT and not so on Tmobile version and also that N900T has an extra LTE band.. I didn't double check on all of this but based on what I read, I felt that it was better to buy N900T, even for AT&T.
Those of you, in the same predictament - just buy N900T!
