LTE on Rogers?

Just wondering if the phone would support LTE in Roger's network in Canada with Tmo's baseband.

Out of the box it should support HSPA+ on Rogers if it is unlocked, however LTE is software locked, but I have heard of people flashing the Rogers/AT&T ROM onto their T889V and getting LTE. Hope that answers your question.

[Q] Galaxy s3, Prepaid SIM

Hello, My friend bought 2 galaxy s3's. I bought one of him. It's AT&T branded, I know I'll need a simunlock. But what prepaid service is compatible with this? Should I just stick with AT&T? I was hoping to go with Straight Talk, Boost, Virgin Mobile.. Either one of these.
Thanks!

I believe boost and virgin are cdma. I know straight talk for sure is a gsm carrier and will work on the i747 variant.

Ah that's right, Boost and Virgin are indeed CDMA. I guess I'll have to google the straight talk

straight talk, ATT GoPhone Prepaid Plan and T-Mobile monthly 4G to name a few.
Unfortunately prepaid plans do not currently offer LTE support so that will be a feature you'll miss out on.
xbeerdroiDx is also correct, virgin and boost are both incompatible because they are CDMA. The ATT version is a GSM device.

4G data on an ATT GS3

Hi
So long story short, my Tmo GS3 got stolen at my work :/
So my mom gave me her ATT GS3 cus she was up for an upgrade,
i been reading its possible to get 4G on an ATT GS3 but so far no luck,
i know i have the right APN cus i copied the one from my Nex4 to my GS3, i set the network to manual and choose Tmo, but still all i get is Edge.
Does it have to do something with the way i unlocked the phone?
I been reading it has to be factory unlock and i unlocked mine by dialing *#197328640# and doing the required steps.
Can anyone help me with this?

Maybe you should try posting in the ATT S3 forums? I'm pretty sure that most people here have the TMO variant, while you are looking for tweaking of the ATT variant.

Don't flash a T-Mobile modem, it will brick. T-Mobile and AT&T use different frequencies for hspa+ in most places, and the AT&T version doesn't have the hardware to pick up the most used T-Mobile frequency I believe. So you're probably stuck with edge

You ARE stuck on edge.... I know it sucks. unless you are in a refarming area http://www.airportal.de/ , (major cities) your AT&T S3 1900/2100Mhz high speed data (4G) band will not work on T-Mobile's 1700/2100Mhz networks. I would sell it on e-bay or craigslist and got your T-mobile S3 again. or get the T-Mobile S4 after you sell your att S3 :cyclops:

[Q] help !! please att data not working on t-mobile 999

ok is there a rom that work right out the box for some sort of data with my prepaid at&t sim card i can make calls get mms, but cant get data i really need some sort of data working today i am rooted, unlocked and have no idea if i should be useing some sort of at&t kernal, or just changeing the apn, which has not worked yet?
can some one please direct me to the right thread or something

So you have a Tmobile T999 with an ATT prepaid sim?
I don't remember for sure so hopefully someone else can confirm, but I don't think the T999 can get better than 3g on ATTs network.
But if you're using the ATT sim, you'll be on their network so you may need to either unlock the phone and/or put in the correct ATT apn.

It will use HSPA on At&t no problem. Sounds like an APN issue. Your best bet is to go to the At&t forum and flash an At&t rom. Just make sure not to flash an At&t radio. Data should work out of the box on an At&t build.

I think it will use HSPA+ but only difference is that att hspa+ is not 42mg like on tmobile. I was getting around 7mg with my friends att sim on my t999.

This is correct. at&t uses the older HSDPA 7/14 and HSPA 21 depending on where you are located. They opted to go to LTE instead of a dual carrier configuration for their HSPA+

What service do you have with the prepaid att service? Did you have to get a new sim card? I looked everywhere on here, but didn't see anything

Verizon nexus 4g lte straighttalk

I've read and searched around. Some say no. Some yes works great 3g only just flash it. I can't find a guide for flashing this phone to straighttalk aside from esn cloning which I don't want to do.... the byop deal from straighttalk says cdma phone can be used but no lte phones. Just want to get the basics working not worried about 4g.
Any help is appreciated

Well I guess cloning is the only way. Anyone have a guide for the nexus?
