[Q] Unlocked i927 on T-Mobile?

Hi,
I have just received an AT&T Captivate Glide i927 unlocked. I put my T-Mobile Monthly4G sim card in the phone, and can make/receive calls etc. as expected. I wasnt expecting to get 4G (I'm not sure the radio is capable of operating on TMobile's 4G?) but I only get Edge and no 3G.
I checked the APN settings and they are correct for TMobile.
Could someone advise what I may have set incorrectly? The phone should work at least on 3G, correct?
Thanks!

To partially answer my own question: perhaps the phone won't work on TMobile's 3G. The phone has HSDPA 850 / 1900 / 2100 frequencies, but the TMobile network has (according to Wikipedia):
1900 MHz UMTS/HSPA/HSPA+ 3G/4G
1700/2100 MHz UMTS/HSPA/HSPA+ 3G/4G[38]
1700/2100 MHz LTE 4G
Does this mean it would only work on 1900MHz or 2100MHz?
Will the Captivate automatically select the right frequency if it's available, for 3G/4G?
Thanks!

If it follows the bands of Apple's phones, your phone should at least get 3G(UMTS) when it does reach your area. The problem is that T-Mobile has not finished their upgrades.
Unless you really have to have 3G/4G, I'd wait until T-Mobile completes their conversion.

Thanks for this astute comment, which led me to e.g. this:
http://www.macrumors.com/2012/05/08...for-iphone-by-end-of-2012-lte-coming-in-2013/
Basically it seems that TMobile 3G/4G may start to work on the 1900MHz band by the end of this year, which would
mean the Captivate Glide would move off Edge and onto the higher speeds.

Free unlock method.

Edit: this method works for everyone it seems. SOME HAVE REPORTED SLOWER T-MOBILE DATA SPEEDS AFTER APLLYING THIS UNLOCK. This has only been reported a few times and it seems like flukes. I however, nor the OP in the linked thread are responsible for wjat YOU chose to do to your device. You have been warned.

What was the default value of "Perso SHA256 "....I changed mine to off but forgot to check the original value...original value should be in Perso SHA256 Flag info

Seemed to work with verizon sim. No longer get the input sim unlock number, but obviously no signal.

Phone wont even get GSM signal ? I thought this phone does support 1900 Mhz which verizon also uses.

It got a signal. But could not pick up carrier or anything just had signal and said searching in notification bar.
But verizon is CDMA so it did not supprise me.

I see that the LTE radio bands are in there, no surprise there. But I also see WCDMA radio bands too. Does that mean that our Galaxy Note 2 have WCDMA radio too? Or is this just an firmware that Samsung uses across all Galaxy Note 2 devices?

I need to try this I have a at&t sim card.

I think we have CDMA also....not that it does much for us as verizon and sprint require the imei to be loaded into their systems.
WCDMA != CDMA by the way. WCDMA is 3G/4G GSM (aka UMTS)
CDMA is a competitor to GSM. It is used by mainly North American and Japanese/Chinese cell phone companies.
I know Verizon and Sprint in the US and AU in Japan use CDMA. Most of the world uses GSM.

All though thinking about it while we may have the CDMA radio, assuming it is the same chip as the GSM and LTE radio then they may have just not sokdered the connections. Seen that before with FM radios built into the bluetooth chip on the Atrix 4G

Which of the bands are our 4G?
Love learning.

Our 4G is UMTS band 4 (1700/2100) same as our 3G. We dont have LTE yet so no *true* 4G

Sweet.
Thank you.

No problems. This kinda stuff is my hobby. Maybe some day I can get a job at a cell phone company as a technician or something.

I can confirm this works, but I could not get data. I got signal and a carrier name with both an AT&T sim and a Straight Talk (AT&T) sim. It would not load APNs, and I don't have the APN for regular AT&T so I tried with the Straight Talk, put in their APN and still got no data. Neither sim is active currently. It did allow me to call 611 on both sims.

If neither sim is active then I dont think it will allow data. Not sure though.

[Q] HELP-N7105(LTE) not getting 3G at all with T-Mobile!!!

Hey guys! I brought my international GT-N7105 Note II LTE model from Asia and bought that unlimited cheap 30 dollar plan. I checked the towers and my area does have those refarmed 1900MHz towers from their twitter. Anyhow, first i just thought it was my house and I have drove from pasadena-los angeles - Irvine - Orange County and have yet to see ANY 3G/H/H+ signals! Always stuck on the E (2G). First I thought it was the SIM problem so I put that SIM to an iPHONE4 and guess what?! There is the T-Mobile 3G right on that upper left hand corner and speeds are decent. Anywhere from 1.5mbps-6mbps. I'm sure it can go higher but looking at that dinky screen is already enough for my eyes! Is there some specific settings I should be doing? Somehow it's NOT locking to the 3G towers from my N7105. I am planning to get Straight Talk's 45 dollar deal at Walmart and choose the ATT since it's got better coverage from what I hear. Thanks for the help in advance and Happy Holidays everybody!!!

I don't think the 7105 has 1900 band, I have 7100 and I get 3G coverage.

Thanks for the reply but according to this: http://www.smartone.com/jsp/phone/english/detail_v12.jsp?id=2553
It should have 1900MHz just like the N7100 except there's LTE which won't work. There's absolutely no excuse for it NOT to have 3G! This stinks and is frustrating!

I see that it has 1900 band but under GSM, when looking at 3G bands it has HSDPA 850 / 900 / 2100 - N7105 vs N7100 having HSDPA 850 / 900 / 1900 / 2100
Dont know if it makes any difference but thats why I steered away from the LTE version.
Try this go into service mode: *#197328640# Debug screen Phone Control Network Control & Band Selection. Check if you can enable or see if you have the 1900 band under WCDMA. Might have to go under Combi Bands and select the desired bands.

Just flowing up if it worked out for u or not?

Bumping this since the op didn't respond. I am having the same trouble and I attempted the fix you provided and found that my N7105 lacks the "combi bands"
I mistakenly purchased this phone for pre-paid here in America (should have gotten the n7100) and it seems that Straight Talk doesn't have AT&T cards anymore and I'm stuck on T-Mobile's EDGE service

I have the verizon model and use it with tmobile
So the last two weeks have been the most frustratying and nerve racking weeks ever as I have tried to get tmobile service to work well with the verizon model i have. And although I am definately still irritated, i have to say that I do get 3G and HSDPA on mine, just not anywhere near my house. This has driven me crazy and until today I assumed it was my phone and the lack of certain bands howev er after purchasing a Tmobile 4G hotspot and activating it on a new 300mb plan just to see how well it works, I have found that it was never my phone that sucked at my hopuse, its Tmobiles service that sucks!. BUT... to get the best consistant coverage with the Tmobile sim in my Verizon model I did have to experiment with the APNs quite a bit, and I also upgraded the modem to the newest one released . For anyone tryinbg to do thius with the verizon model, make sure your APN for T-Mobile US or T-Mobile Data (I personally have started using it as T-Mobile Data) has "None" typed in for the username and for APN if your using LTE device type in "fast.tmobile.com" instead of the epc.tmobile...... or whatever it is. Does anyone know if flashing a modem or radio or even just the rom from the tmobile section would help at all? Or would it just **** up the phone..

Despite not getting 3g (since I lack the appropriate physical antenna apparently) I get way better cover with T-Mobile (through Straight Talk) I have to say compared to Verizon. Maybe my Note 2 is much better than my old Thunderbolt or maybe T-Mobile is just a bit better. Nevertheless every building at my university is made of reinforced concrete so you'd be hard pressed to get any reception in the classrooms. I find in places I had no service I have service, and places I had some service I have great service now.
Back on topic though:
I can get the 1900mhz through GSM but that isn't the same and my phone lacks whatever that Combi Bands thing is. So I don't know if it is a lost cause or not. I just figured I'd bring this back up since the OP never responded and I am in the same boat as they are (were?). Maybe a solution can be found or just "it ain't gonna work."

Just following up I have returned my N7105 in favor of a N7100 and get great H+ and 3G through T-Mobile/Straight Talk.

Fwiw, net10 is basically the same as straight talk. When you buy the $15 simcard pack from bestbuy for net10, it comes with 3 different sim cards in it. One of them is a micro sim that fits in the note2 and runs on at&t's network.

[Q] Verizon Note 3 on TMO

Hey guys, trying to get a Verizon Note 3 to work on TMO. I have a TMO rom installed in a safe strap, got it all running for the most part, but can't get data to work right. I used the TMO apn posted on TMO's website. When I switch from GSM only to LTE/WCDMA/GSM or WCDMA/GSM, I get no voice data or text. If I look at system status, on the mobile network state, it says Connecting, then Disconnected. And it just sits there and toggles back and forth. Any ideas? If I stay on GSM only, I have data, voice and text, but it's all on EDGE. Any input would be greatly appreciated!
I used this apn. http://support.t-mobile.com/docs/DOC-8373

1 of two things
1) Verizon model doesn't support GSM fully
2) doesn't support 1700mhz freq which T-Mo uses, it does support 1900 apparenrtly but you might not have that in your area.

If I switch to the Verizon stock rom, I can get HSPA+.
I was under the assumption (maybe incorrectly) that the phones for the most part were all the same. Could I try flashing TMO modems to see if it unlocks the 1700mhz band? I live right by New York city so I would imagine that I would have the better frequencies here.

It is NOT about unlocking frequencies. The phone itself is NOT sporting those frequencies. i.e. Hardware is not there.

Ok, I miss understood then. Thank you for the reply!

let's not forget to mention that one is CDMA (Verizon) and the other is GSM (T-mobile)... or unless I missed it and it was somehow implied?

TMOBILE T989 in canada

I sent this phone to my friend in canada. (Mississauga, ON).
He went to get the mobility sim and was told that this phone will not work with them, they need AWS 1700/2100.
What other carrier this phone can be used with and what other cheaper plans are available in that market.
Will rep.
Thanks

That's weird, according to here http://www.gsmarena.com/samsung_galaxy_s_ii_t989-4129.php the phone has the 1700/2100 band. Hell, T-Mobile operates it's "4G" network on the 1700/2100. I've used my phone in El Salvador with Claro and they run on the 1700/2100 band and I've gotten HSPA+ just fine Tell your friend to try the Mobility sim anyways. He should be getting HSPA+

T989 in Canada
Don't know why it will not work on MOST carriers. I have one on Rogers and was running T-Mobile software with no problem A friend tried to run my phone on Wind and it was a no go. The phone came with Kodo Software on it , so I guess it worked there too I am currently running a set of software called SHADOW that works very well on the Rogers service..

Yes it will work, I use this phone on Wind mobile ( AWS ).. its a telus/koodo t-989d
There are guides on XDA to unlock the phone, You basically root, then install the t-mobile v. 4 radio, then enter the test menu and do a couple of things. It was super easy and I have done it to a couple of 989d's now. keep in mind, you HAVE TO HAVE THE ORIGINAL STOCK ROM to do the unlock properly.. after you have unlocked, you can upgrade to the newer ver. 6 radio and use newer roms.
