[Q] 800mhz CDMA on I747?

Hi all. I747m locked to Virgin Mobiles network. Does anyone know if I could run on Tbaytel's 800mhz CDMA without a SIM unlock? Visiting family for xmas in rural Canada and would really love to at least have talk+text enabled. Thanks for the help!

Your i747m doesn't have a CDMA radio, so to directly answer your first question, no.
Poking around a bit, though, suggests that TBayTel is also running a HSPA+ network, and that they are also directly selling the i747m themselves - so the i747m is obviously compatible with at least their HSPA+ network.
I do not think you will be able to do so, however, without unlocking the phone. You might try here if you want to go through with that (the instructions are confirmed to work with the i747m so long as your device is running the stock Jelly Bean ROM - rooted or other wise - or, presumably, another ROM derived from those.)

Ahh too bad! I have a tbaytel SIM as well however I left it on the east coast. Unlocking for 4 days use isnt really necessary IMO. Thanks for the reply!

Thanks again smel! Wasnt sleepy yet so I went ahead and used the hidden menu unlock from the post you linked. Tested with my sisters Tbaytel SIM and worked like a charm. Merry whateveryoucallit-mas and congrats on surviving the apocalypse!

[Q] I have a T-Mobile S4 that refuses to select LTE for other carriers

Hey Y'all,
I've seen the other threads and I know that LTE works for AT&T but for the life of me, I cannot get it to select LTE
at all. I've tried the connections-->network mode menu and whenever I select LTE+WCDMA+GSM it always reverts
back to WCDMA+GSM the moment i back out of the menu. Also when using the *#2263# and I try and select it
via that way, I get bars but no data. Can anyone help me shed some light on this?
Is there another way to prioritize LTE? Do i need to flash a new kernel or modem?
Thanks guys!

Is lt available in your area?

Yea that's whats bugging me. I put the AT&T sim back into my GN II and it gets LTE easy. I'm still within the return period
I just dont know if I'm missing a step or if the phone is defective. But it gets T-Mobile LTE ( in what few places get it
where I'm at ). So I don't know

No I did not. I just did the unlock method that was posted here. So forgive the noob question, but I would have to flash
the AT&T radio to get LTE? Or is this just a troubleshooting method you want me to try? I just thought I wouldn't have
to flash the AT&T radio since it supported the bands Out-the-box.

Technically, you shouldn't have to. It supports 700 MHz LTE out of the box. The T-Mobile S4 is the "best" version because it supports both AT&T and T-Mobile bands out of the box. The AT&T S4 supports AT&T and T-Mobile LTE out of the box, but not T-Mobile HSPA+ (AWS) without a mod.

It's more along the lines of a troubleshooting method. I believe I read another thread exactly like yours and the solution was to flash att radio. Think of it like a regular am/fm radio. All the hardware is there, but without something to control what stations it can play, how's it gonna know what to play?

The network is decided by the SIM card (the entire purpose of GSM). With an AT&T SIM, he should still be able to pick up T-Mobile LTE (AWS LTE is what T-Mobile uses and it's supported in all AT&T devices). My AT&T Note 2 gets T-Mobile LTE, just like my T-Mobile Note 2 does.
Also you can't cross-flash modems because the partition sizes are different; ROMs may be compatible (that's the case with the Note 2) but not the modem. If you flash another device's modem, you'll lose your IMEI (until you flash back the correct one) and your device will bootloop with no signal. From experience.
IGNORE THE GUY TELLING YOU TO FLASH THE AT&T RADIO. YOU'LL BRICK YOUR PHONE.
----------------------------
I just remembered the reason. AT&T won't activate LTE on a non-AT&T phone (on their end on the computer) unless you lie to them and give them the IMEI of an AT&T device. 10000% sure. Fixed this for another guy with a T-Mobile Note 2 trying to use it on AT&T. I have one for you. You go on chat online and tell them you're not getting LTE. They ask you for an IMEI number of an AT&T LTE device (it doesn't have to be your S4's) and then they can activate LTE on their end. I happen to have an IMEI of an in-store HTC One on hand. I'll PM you.

Thanks for all the help guys. I already have the GN-II's imei listed on my account however and with the LTE feature code on my account thanks to my buddy who is a rep at the att store. I'm gonna meet him in a few minutes to get another sim card just to give this another shot before i do an exchange at t-mobile seeing as t-mobile is more anal about doing exchanges unless they can physically verify in store what you're *****ing about.

You dont need to be so rude first of all. Secondly I never told him to do anything, i simply asked if he flashed the radio and told him it was a troubleshooting method. Meaning, research it before you do it. Just like anything else.
Secondly, others have gotten LTE on their T-Mobile devices without talking to ATT. I already stated i was using the top of my head for diagnosing and never did i tell him to do anything. And since i was going off the top of my head, i remember being able to flash ATT radios to the S3 and S2 of T-Mobile. Also, he has a T-MOBILE DEVICE wanting ATT LTE on it, not the other way around as you are thinking.. Any how, we are two very smart people, we need not argue with one another and telling the op to ignore someone. Thats just flat out rude. Especially since i never said "go flash the ATT radio" i simply asked a question.
To the OP,
Have you set up your APN configurations for ATT?

I'm sorry if I came off as rude to you; I was merely trying to tell him to not cross-flash S4 modems as it can brick the device; you have to be careful what you tell people to do if they're coming to you for help. It's not like with the S2. I correctly said he has a T-Mobile device and wants AT&T LTE on it, and as I said before, I've fixed the issue with someone who was in the same situation with a T-Mobile Galaxy Note 2. Like I stated, the phone itself is capable of 700 MHz LTE, which is what AT&T uses. You don't have to flash any modems. It should just work. The fix is above in the last paragraph.

Did you try changing APN configurations?

Update: I switched the phone, did the unlock process again and....it still refuses to select LTE. I dunno. At this point I'm at a loss and thinking that it might have something to do with the unlock process itself. I might just do one more exchange and pay for the unlock. Can someone who has AT&T LTE on their S 4 do me a favor and post their APN settings so I can compare just to be absolutely sure it's correct?

I have a T-Mobile s4 that I put my AT&T SIM card in out of my AT&T galaxy note 2 and lte works fine. My issue is, I have random losses of network signal then it just comes back moments later while using the T-Mobile s4 with my AT&T SIM card. I used the unlock method posted in the T-Mobile s4 thread, rooted and flashed the Jedi Rom from the T-Mobile s4 thread. Can anyone shed some light on this issue?

[Q] model SM-900W8 bands and questions

so i just got my SM-900W8 for Wind mobile today, had to buy it with two months service, but then was able to send half of the money i put down on that service over to my old account, switch the sims, and now i have my same old number and plan on my new note, and i'm only out an extra 20 bucks (still bull****, i know, but i wanted it today and wasn't going to deal with waiting, for any reason.... maybe too impatient lol)
anyways, after i bought it, i stopped by the bell store and asked what model they sell... they showed me the box and it was the exact same model number... SM-900W8. i then went to rogers, same thing, and telus i presume will be the same since bell and telus share towers etc
so, my question is, if i unlocked my phone, could i simply go get a bell rogers or telus sim card, and throw it in, and have it work? the region issue is a non-starter for two reasons - first i didn't even have that region lock sticker on my box, but second, the robelus sims would all be the same region, so it shouldn't matter in the least. what i'm wondering is, would the bands be the same, or at least some of the same to the point of working? i know that wind uses AWS bands and robelus does not, but since they are the same model number, is it possible that they have radios that are compatible with all four carriers in this phone?
if not, can someone explain to me how to find out what networks this phone would work on? i mean, it sounds like people are unlocking their tmobile phone and using it on att, and from what i remembered, att is not aws, and i thought that rogers and att phones worked together... ARGG what gives here?
also, are the tmo phones the same model number as mine? or did they use different phones than wind this time around?
finally, if i'm looking to root this or put a rom on this, am i looking for the tmo roms and other stuff like i was with my sgs3 or am i looking for something else with this new phone? where can i find this info... i haven't been able to find much about this yet, i guess not many people have this phone on wind yet

Thanks for the answer, but I don't know for sure what bands the big three use, can anyone tell me if this phone will work on those big networks?
Also, any answers to my other questions ?

Rogers, Bell and Wind all use the SM-900W8 variant probably with just a different modem / QCP file.

So does this mean that there is some chance of, in the future when things get cracked, of flashing a new modem etc onto it our something

to answer my own question, yes, i unlocked my n900w8 from wind with an unlock code, and i was able to see whatever networks were attached to the sim i put in it. rogers, bell, telus, koodo, virgin, fido, wind, probabaly chatr if you really wanted to use this device on that dumb ass carrier
so yes, you dont even need to flash other modems... it just works
i did try flashing bell/rogers/puerto rico roms on my device and all had the same result, it all worked, and it all worked fine

Samsung galaxy note 3 SM-N900W8 from videotron (canada)
Hi, i have a Samsung galaxy note 3 SM-N900W8 from videotron (canada) and i unlock with a code to use it with fido and the phone show only the 3G internet, is there a way to enable the LTE? when i go to setting mobile network, network mode show me only 3 options WCDMA/GSM (auto connect) or WCDMA only or GSM only. I tried to root the device to do like this forum said ( http://forum.xda-developers.com/showthread.php?t=2489766 ) and when i root it it says pass but it stuck on rebooting and something red is written on the next line and samsung logo is there too. anyone can help me to enable the LTE network?

Galaxy Note II Network Switch

My fiance has a Galaxy Note II that was registered with either Telus or Bell (our friend let him borrow the phone until he can get his own) and our network is with Wind Mobile. I looked up on whether or not it's compatible and supposedly it should be but there has to be some "adjustments" on the phone. One website mentioned Odin and QPST but we don't know exactly how to use those programs to change the network to AWS. Is there anything else we can use or do that is much simpler or at least simple enough to understand with proper instructions, preferably one that doesn't brick the phone, unless specifically detailed about how to unbrick the phone, because again, the phone belongs to a friend of ours and we are giving it back to her when he gets a new phone. Thanks!

Our simchip is for wind mobile, what we're looking to do is be able to connect to the wind mobile network but his frequency network is not AWS which is what he needs on the phone to be able to connect to wind.

[Q] T-Mobile M919 To MetroPCS

OK, I have looked and looked at a bunch of threads in this section, and I am either missing something, or I'm just totally blind. I just bought 2 T-Mobile M919 phones, and one of them i am going to Use on T-Mobile, but the other one, on Metro-PCS. I understand that there is 2 different versions of this model, the M919, and The M919N (METROPCS) . I know how to unlock them. (I found those threads) I know how to put Cyanogen on either.. But what i cant seem to find is, How do i take the M919 and use a SIM card from Metro-PCS and make it work. I'm sure i have to use a different Firmware with a different modem. But i am really confused as to where i can find all of this info that i need. I just cant seem to find it. I know that Metro-PCS uses T-Mobile networks, but i am sure there is a different APN for both.... Can some one direct me to a thread or a link or 2 to find this info... Any and all is appreciated.
I also used XDA to (Successfully) use a Samsung SGH-I727 Galaxy S2 (AT&T) W/ Cyanogenmod 11.2 and a different radio on T-Mobile!!
Again any and all help is appreciated!!!

Since day one after I got my s4 from metro I rooted and flashed t-mobile roms and since that is all I use. My Sim card is metro but my apn is t-mobile us lte and never once did I manually change it my self or sim unlock my phone. Hope that helps your ?
