Had a note 2 that was busted, sent in for repair, they sent me a refurb back.
Noticed on this one internet would sometimes stop working until reboot. Until further investigation found that none of the HSPA bands work. (APN settings are correct). When trying to connect on HSPA it looks like the radio crashes, and it completely drops signal, and you get the stop sign icon for the antenna.
Tried every HSPA band through *#2663# (or whatever menu you use to disable LTE).
I dont want to send it back for repair as it takes Samsung a freaking month to "repair" it. Any ideas anyone? This hapenend with the stock rogers modem, and with the latest rogers modem.

Bought my phone form Rogers. LTE was working fine.
Was going to USA and paid an online company to send me unlock code.
Used it and went using Tmobile which only has EDGE data.
Just got back swapped back in my SIM From fRogers and can only get EDGE speeds.
Tried reboots rmoving SIM card.
Also made sure settigns were correct for Rogers APNs and also that toggle was on for GPS/HSPA/LTE.
To no avail.
Briefly, I toggled on and off the apn setting from ROgers LTE to tethering LTE and low and behold it seemed to work.
But now it is back to stuck on EDGE and nothibg I am doing can help.
Can this be a byproduct of the unlock?
Is my LTE faulty?
I s there some hidden menu where perhaps a setting can be changed for a fix?
I am depserate as the alternative is to return the phone and they are on backorder everywhere now.
There is no lte on tmobile yet. Second the tmobile note 2 has dormant radios that will only activate the lte capability by software update.
Im going to research your problem a little more ill send you a pm as to why it isnt going back to lte functionality if I find out something first...

I have a Canadian note 2 that had working LTE.I had it unlocked via a code emailed to me then next used it on tmobile at edge speeds.
Since returning home i cant get back onto data speeds above edge despite reboots.Simcard/battery pulls.
I ensured my network and apn were correct and that in setting under mobile the toggelchoice for auto including gsm//hspa/LTE was selected.
Are there perhaps some deeper settings via dialer code than might be able to turn back on the hspa/lte radios?
I've been using an S4 for about 2 weeks now, no problem. Last night I realized a text I sent never went through, and today my lock screen says "No Service" or "Searching" (despite the device showing full signal). I can't send/receive calls or texts, and I don't use a data connection. This SIM is also new (~2 weeks), and the device is neither rooted nor running a custom ROM. I've tried everything I could think of, like:
reboot
pull battery and SIM
confirmed APN settings on t-mobile site
tried alternate, non-"LTE" APN (epc tmobile com)
tried every network mode setting (GSM, GSM/WCDMA, etc.)
reset APN to default
turned on mobile data connection
manually scanned for networks (wouldn't connect to AT&T or T-mo)
select network automatically (wouldn't connect)
complete factory reset
I tried my SIM in another T-mo phone and it works; tried a different SIM in my S4 and it doesn't work. All other T-mo phones in my household are working fine. My S4 is definitely the problem here, but I don't see how the radio would just stop working after 2 weeks.
Has anyone else experienced/seen this? I never have, and it's driving me up a wall. I'm going to try my local T-mo store tomorrow, but I was hoping to fix it before then. Any help is greatly appreciated.
EDIT: I purchased the phone new on ebay. For a minute I thought the seller might have reported the phone stolen, but I checked the IMEI and it's clean.
Ive experience this but my service came back in about 25 minutes I did reset reboot battery pull sim pull it just came back on its own
Unrooted Samsung Galaxy S4 Up and Running
Rooted Mytouch 4G Slide retired
Rooted T-Mobile Sidekick Touch Obliterated
Rooted Mytouch 3G Slide Lost
Rooted T-Mobile G1 Dead
So I finally got to T-mobile today. Unfortunately, my hunch was right: the IMEI is blacklisted. Their in-house system must be more up to date than their web IMEI checker.
Time to solve this issue elsewhere.
hey i recently bought a note 4 for verizon and used it on t-mobile.
now it worked and i changed the apn settings manually. except:
1.) The phone would lose signal really quick in certain places and have the circle with a line thru it and it would take few mins, sometimes even have to restart phone to get service back ( i am in a 4g lte service area and it works fine on other devices)
2.) when i was in a call, the option to be on the internet DID NOT WORK. it would say check network settings or something of that sort.
3.) sometimes during a call even with full signal bars, it would hang up and say 'sim not found'
is anyone else experiencing this problem(s) also, or was it just a faulty device?
please any feedback, or insight would be appreciated!
Has it been more than 24 hours activated? Although not a note but her iPhone went from Verizon to t-mobile and she was having issues with data for about 48 hours.
I don't think its just your device (unless we both have faulty devices). I am having the same issues with my Verizon Note 4 on T-mobile network. When I am on a call that requires a keypad entry, it doesn't recognize that I pressed a number (same for voicemail).
My phone also loses signal and 4g in certain place (I thought it was tmobile at first but I was at starbucks with two other friends who had tmobile..they had 4g lte and phone service just fine while my note 4 had neither.)
I was wondering if it was a note 4 issue but haven't found many forums that discussed these issues specifically for verizon note 4 to tmobile users. Please let me know if you are able to find a solution to this problem.

You are correct. I have a Verizon Note 4 that is having the same issues. I'm considering trading this for a T-Mobile note 4 but I don't know how to do that other than craigslist....too bad there is not another way....
I have a problem. I unlocked my note 2 via service menu and had someone else do aws flash for me. Now it connects to the network but intermittently. Can't send text or data all apn settings match. Never goes over 2 bars and is never lte on ocation I get h+. I live in Vancouver and have never had a problem until now. Anyone have an idea of what the issue could be. Thanks
Hello there, I'm in need of your help again.
My SGH-M919 has a problem, it cannot connect to 3G/LTE (Not even EDGE). My carrier uses the 850 mHz band for GSM and 1900 mHz for UMTS, so the phone should be able to use them. The thing is, it doesn't. It only connects to GPRS and the signal is very erratic and weak (Usually 2-3 bars). Sometimes I get SMSs from my carrier saying that I missed like 5 calls when my phone never rang once. I live in a zone with good 3G coverage, so it's not the signal.
I'm currently rooted on Android 4.4.4 (NH7). I already tried selecting "1900 WCDMA" in the *#2263# service menu but that only causes the phone to lose all the signal (And it's a problem to change it back, without signal the service menu doesn't work and I cannot change the Network Mode in Settings).
I've tried to select "WCDMA only" mode before, but my signal just goes to zero (The circle with the slash) before changing back to "LTE/WCDMA/GSM (Auto connect)" automatically.
I also cannot use the Network Operators option. Using "Search now" makes it search for a few seconds before showing the message "Error while searching for networks". The "Select automatically" one shows the message "Unable to connect. Try later" and then connects back to my carrier (Movistar)
My APNs are configured (They did it themselves when I inserted the SIM, but I've configured them manually before). The SIM card works, I tried it in another phone and it got 3G immediately, I also tried another SIM card on the GS4, but the result was the same. Someone told me to upgrade to the latest firmware (NK2) while someone else told me to flash the MDL modem. (Is that even possible? I read something about KNOX blocking all downgrades after 4.3).
Since I couldn't find any direct solution to the problem, I'm recurring to you.
Thanks.
P.S: I didn't change the LTE Band Preference option in the Service Menu because the last time someone messed with it, my IMEI/Baseband went completely nuts, I thought the EFS got corrupted, but they magically appeared everytime I enabled the Airplane Mode (So I was able to select Automatic in the ServiceMenu and they got fixed). Also, I don't live in a LTE area although once during a very strong thunderstorm, I got 4G for a few minutes before going back to G).
*bump*
Any ideas?
Did you put a check mark in data roaming?

I've tried with and without it, it doesn't make a difference anyway.
Does it show you have an ìmei # other than all zeros?
Don't post it just a yes or no.

My IMEI is fine, the phone connects to the carrier network but it stays on GPRS (and the signal is always dropping)
Update to full NK2 firmware and see if that will fix it

I'll try that later. Will I have to re-root and re-install TWRP after flashing NK2?
I have a similar problem with my M919 on the Tmobile network. Using the *#2263# menu I can not get mine to work on WCDMA (4G) either. I can chose GSM /LTE only and my phone works normally but no 4G signal. If I chose WCDMA I get no signal. I can see it trying to connect and immediately dropping the signal. If I choose any option with WCDMA included it has erratic signal and will lose the signal most of the time when I try to make a call. So basically I have the choices of GSM only or GSM/LTE only. Before I discovered the secret menu I was stuck with GSM only in the phone's settings. This has been going on for months. Tmobile changed my SIM card and it didn't help. I've rooted and unrooted my phone (using autoroot) and even tried different modems (even worse signals) and now am back to stock rooted NK2 firmware and modem. I have given up and decided to get another phone (not an S4). My wife's S3 gets great 4G signals in the same location by the way. I wonder if anyone knows why our phones can't use 4G. I am beginning to think it's a hardware problem but I'm way out of warranty on mine.
