Just wondering if anyone had any information (and knowledge to share) about the likely modem for the Note II. I am on Bell's network in Canada (Toronto area).
There is a known issue with the Note where a weak LTE signal causes the modem to lose all connectivity (all voice, all data) until a reboot. I have seen reports of people in other forums (ie. HowardForums) with a similar issue now on the GS3 which worries me. I have read (but cannot confirm) that a few Samsung LTE phones have had this issue on Bell's LTE network.
Since the Note II will be using a Samsung chipset instead of a Qualcomm one, will this mean a different LTE modem? Or is Samsung just taking a current, popular LTE chip and attaching it to their Exynos quad?
I was curious if anyone knows the answer to this. When I had my i747 with the S4 processor it seemed like it got better 3G/Data connections here on Straight Talk than my i9300 does. Basically what I'm wondering is for the LTE versions of these phones such as the N7105 and i9305 are they simply adding in a second modem that solely uses LTE, so it would essentially have their standard modem for your 3G/HSPA connections and then switches to the Qualcomm for the LTE connections? Otherwise are they using a completely different modem that also handles your regular 3G/HSPA connections? I've been itching to grab an international N7100 as soon as possible, but I was thinking maybe I should try and hold out and get one of the US variants with the qualcomm modem as I've seemed to have better connections with the devices running the qualcomm chipsets. Does anyone know the answer to this?
Quick summary would be since I'm on Straight Talk and can't use LTE, if I waited for the AT&T version would I be using the same modem that's in the N7100 to connect to 3G/HSPA+ while the LTE modem sits idly by?
I just got this baby unlocked, FINALLY, and was wondering if I need to flash any modem/radio to get the best possible performance.Thank you all for your awesomeness!
I don't think there's any specific modem that would work best under those circumstances, particularly as modem performance seems to be location-dependent; if you're curious, you could just cycle through all of the available modems and see what works best for you in your area.
I believe you're in the wrong forum. This is the forum for the i747 Galaxy S III.
If you're on T-mobile, you'd have the T999, which is in a separate forum over here
The differences are the T999 doesn't have an LTE transceiver and the radio uses the AWS band rather than the PCS band for HSPA.

...which he unlocked, and now wants to use on the T-Mobile network. This does not mean he has a T-Mobile device.
Hi,
Based on the wikipedia page, the AT&T doesn't support AWS frequencies in HSPA+ but it does support those frequencies in LTE. So I'm assuming the underlying hardware is actually the same, just no AWS HSPA+ support in the firmware.
Has it been proven (or disproven) that the hardware is the same? I've seen a lot of discussion but can't find a clear answer.
Similarly has anyone got an AT&T Note 2 working on T-Mobile (or tried and failed)?
^^^ a user already tried to flash t-mo radio on ATT's i317 and reported unable to get signal. 2G data works on unlocked i317. we still have discussion going on : http://forum.xda-developers.com/showthread.php?t=2049970&page=2
I would expect it takes more than just changing the radio. Something has to control the radio and the ATT ROM doesn't know about the necessary mode. Can the entire firmware be changed to T-mobile? That's what I'd try if I had more experience and could safely do such things! I don't know if flashing a T-mobile ROM changes everything over to stock T-mobile configuration....if it does that should work if the hardware is indeed the same.
Thanks for pointing out the other thread. Might as well continue the discussion there since you guys have started already.
A couple of questions...
I'm thinking about a Galaxy S3, and had a few questions. Looks like there are a bunch of different variants, and I'm not sure of the differences (or if it matters). I'm using simple mobile, and am looking at both the t999 and I747 for AT&T. Any significant differences? Are they both sim unlockable? Anything else I need to be aware of?

Id suggest the T999L. (Its the only one they sell now). It is compatible on more frequencies/bands than the I747, and if you use it on T-Mobile's networks, it has the potential of being twice as fast as the I747. (I747 I believe can only work on the slower of the two LTE bands used, while the T999L can work on both).
They are both unlockable, but the T999L was patched against our unlock method prior to its release. So you either have to get the code from the carrier who sold it to you, or pay someone $5-10 online to do it for you.

Thanks for the info. Looks like the T999L is going for > $100 more than the other 2 on ebay. Not worth it to me. Also have no idea what speeds simple mobile provides. Any difference between the standard T999 and I747? Are you saying that the I747 has LTE capabilities, but the standard T999 doesn't?
That is correct. The T999L replaced the original T999 when T-Mobile rolled out LTE. None of their devices were LTE capable before, because they couldn't use it.
I will say that the I747 using LTE on T-Mobile s networks, may still not get quite as good as even the old T999, if your in an area that has hspa+42. No idea about simple mobile and what they use though.personally, I think either T999 variant will be superior to the I747 when on T-Mobile networks. There are threads where people are trying to force the I747 to use different frequencies because they want better speeds than what they are getting.
And again, there's just no way to know for sure with SM.

OK. Doing some more research--lots of info out there. Seems that the difference between the T999 and i747 is that the T999 has support in the 1700 band for HSDPA, while the i747 has LTE capability. It appears that T-Mobile is migrating away from the 1700 band in favor of LTE. This chart includes LTE coverage for a bunch of cities, including pretty much anywhere that I spend significant time.
This article indicates that SM should operate on LTE. So, from this info it looks like the i747 might actually be the better option--although I think that either one will work fast enough for my needs. Basically, most anything faster than EDGE is fine for me.

Just a bit of an update. Got the 747. Getting 9 mbps download speed, which is the same as my wife on the t mobile network (I don't know if hers is lte or not). So, success.
