[Q] can tmobile t989 run on at&t 4g???

I have read about skyrocket getting t mobile 4g service but i never got a clear answer to my question so far i get 3g service on at&t network using tmo galaxy s2 t989.
i am using the Jedi mind trick v8 ICS ROM
I have tried flashing an at&t modem once which did not work well. Please share your thoughts on this if you have succeeded in getting at&t 4g :fingers-crossed:

I don't think so, t989 is not lte by default, even it has 1700mhz. But if you can find a radio to enable it, that will be a different story.

It will never work on att lte. Doesn't have the hardware for it. It will say 3g but will have T-Mobile "4g" speed. 10+mbps

can you explain this?

i have a feeling it is possible but not sure how to do it exactly because it has worked the other way with the right modem and kernel.

Did you read the thread? Ultimately, the thread proves that our phone doesn't have lte so we won't be able to connect to any lte network. However we do get h+ on att though... which can go up to 20+ mbps which is more than enough.

Oh and if i remember correctly. I think someone even took the two phones apart and the antennas are definitely different...
Now i just realize I've been on these threads for too long to remember what went on last year... time for a new phone

thanks for the help so i understand you can't get 4g lte but i can get 4g hspa+ but i have been only getting 3g so far. So could you please tell me which radio to flash and do i need to maually switch bands through service mode or any of that sorts of stuff. thanks in advance. I would be happy with hspa+ if i could get it to work. and wat apn setting should i use?

Before getting to the radios. The icons might say 3g but you're really getting 4g speed. Have you done any speed test? If you're getting below like 3mbps then you probably need to change radios. For some phones stock radios will work with att. But if it doesn't then go over to the skyrocket forum and choose a radio. There should be threads for it. You don't need to change kernels that has nothing to do with it. Only radios.

[Q] SGH-t889

Hi guys,
Maybe someone can answer this.
I just got a Note 2 model t889 and I live in Montreal. I found out that Rogers (my provider) uses the i317m model. Would this make a difference in my LTE speeds? The t-Moblie unlocked one I have now is only getting around 8mbps down and 1mbps up. When I switch my sim back to my iPhone and do the test, I get 35mbps down and 30mbps up. Is there anything I have to tweak to get it to LTE speeds?
Any help is appreciated.

The t999 don't have Lte yet. Even if they did turn it on I don't think it is compatible with Rogers Lte.
Sent from my SGH-T889 using Tapatalk 2

Some people claim that t mobile version has same hardware like att, just firmware disable/enable some frequencies. Roger version looks like att (as far lte is concerned). Theoretically seems like would be possible to flash firmware to make that phone fully compatible with rogers network. Check att note2 forums and you may be able find more informations

check this:
Double wrong. Verizon has a different RADIO frequency than AT&T and/or T-Mobile. It is impossible to update/change the radio for a sim on att/tmobile for it to work on Verizon phone. Like said before: Verizon is CDMA (code division network based) AT&T/T-MOBILE is GSM (global system network) now let me Synthesise, IMPOSSIBLE for the simcard to work in Verizon phone with out the appropriate radio for the network!

some of the verizon phones are "world phones" and have both gsm and cdma. all verizon lte phones have a sim card but only some have gsm. I don't know anything about the verizon s3 but you would be better off asking in the verizon s3 forums.

I know what world phones are. Was just stating to the other dude who thinks it completely impossible.

Yes you can, see this right now you can only get E speed on it. My S3 is actually flashed to Pageplus and I can use it with any GSM carrier here in the US, it's fairly easy to do but like I said you only get "Edge" speed for now. I've use Net10, Simplemobile and StraightTalk, any GSM will work you can also flash to other CDMA like Metro, Cricket or Pageplus.

See... This is what happens when a ignoramus tries to be smart .. You don't know what you're saying.. It is a proven fact that you can't put a GSM into a NON-gsm phone and expect it to work! (i tried it.. And it failed.. Invalid sim[in a unlocked vzw phone])

yes but havent tried
there are several places saying it is totally possible and ive called verizon trying to see what they would say and the answer i got, at least for out of the country GSM, is that the S3 comes "unlocked already" and you just put in the sim card from whatever out of country carrier you want. apparently that came with the 4.1.2 update to the phone. Now putting with a us carrier might be different but i cant try it because i have my phone flashed to metropcs and i cant just put a metro sim card in it. here a few places i found just by looking on google

U actually can use the Verizon variant s3 on tmobiles network as the s3 is a world phone, now here's where and why most ppl don't, Verizon's network is CDMA as we all know and T-Mobile is a gsm network, so with the s3 being a world phone it can be used on a gsm network but u will never see 4g or even real 3g speeds, Verizon's s3 doesn't have the ability to pick up anything but "E", edge speeds on T-Mobile so is it really worth it? Not in my opinion, if I'm going to blget an s3 I want the full functionality of the devices capabilities, just saying though lol

I can say with some certainty that u will not see 4g using a Verizon variant s3 on T-Mobile network, yes its a world phone and yes u can get it to "work" on T-Mobile but it doesn't have the right kind of internal for gsm 4g network speeds, the most u will see out of it is E or edge, 2g speeds, at least until the towers get updated

I can't say for certainty but as of right now any unlocked world phone from a CDMA based network will only pick up 2g or edge network speeds, it may say 3g or even 4g but believe me unless ur in an area where towers have been remapped u will not see anything above 2g ,maybe base 3g ,only because the radio isn't designed to pick up the gsm frequency, now in the near future cdma will be phased out so u may be able to get 4g in the future but not as of now

Weak LTE connection in strong signal area

Hey guys!
I recently switched over to T-Mobile from Sprint. After looking at the data maps, it appears that I'm supposed to have a very strong signal/connection with LTE in my area. This isn't the case with my new GS4 however.
I get 1 bar at best and at times the signals get choppy. HSPA+ is strong, phone calls are clear, but LTE is lacking.
I know when I used my GS2 with Sprint they had things called modems that you could flash for varying connection performance. With the HTC EVO 4G, you could flash Radios.
Does the GS4 have anything similar to that effect? Do different ROMs have varying efficiency in terms of connectivity?
I'm just trying to optimize my connection. Any help would be deeply appreciated. Thank you!
On an interesting note - my IP is showing as Washington from T-Mobile even though I live in Denver..

I am having the same issue here in Texas. Sucks that there is no radio support and have alternate radios to flash.

You might have decent 4g connectivity. Try switching it to gsm/wcdma instead of lte/gsm/wcdma. When you have it set to auto, it will always try to connect to lte. You should get a pretty good download speed on gsm...

I can confirm this works. I have a T-mobile sim inserted in my Verizon Note 3. Make sure you change your apn settings. I've had issues sending and receiving MMS with the suggested T-mobile apn settings. I have APN protocol set to IPv4 and APN roaming protocol set to IPv4/IPv6. This worked for awhile then it stopped working after I started playing with settings again (I just can't leave things alone). I managed to get mms working using hangouts to send and receive mms. I had to open hangouts go to settings - SMS - Access point names - select fast.metropcs.com.
Writing this just made me think of something else to try. I will try and report back. I would love others feed back to help refine this beast!

Have any of your tried and make sure that Verison Note 3 gets T-mobile LTE signal?

Tmo lte is not everywhere yet, should be able to at least get hspa. As far as I know, all of the gn3 variants in us / have lte capability should work. Att ones only work in refarmed areas.

Ok. I ask because it came to my attention during research into my own recent phone purchases that Verizon will only allow LTE phones like the Note 3 onto their network via a postpaid plan, which means a contract. As long as you're planning to go back to Vz on a 2 year postpaid contract 6 months from now, things should work out fine.
As for the swap helping things in your area, from what I've read, the t-mobile/vz spectrum swap won't even be finalized until sometime this summer. Then they've got to actually gear up to use it. Could be a year or more before it sees wide use.
Also, even though it's Vz spectrum, it's a block that Vz never used. So there's no guarantee any existing phone will be able to access the new spectrum, including a Vz Note 3, even with some sort of radio firmware update. The new spectrum is great for the future, but I wouldn't count on it swinging anything in T- mobiles favor in the time frame you've indicated.

Sorry if this has been asked. What about using unlocked tmobile note 3 on verizon network? Is it possible? I don't know much about what bands needed for verizon . I'm thinking about switching to verizon if I can use tmobile note 3 on their network.

Nope. The T-mobile Note 3 doesn't have a CDMA radio, for one.
