I've recently bought an S3 GT-I9305 second hand. Everything works fine accept I can't get 4G. (my sim gets 4G in another phone).
The phone isn't stock - it's got CWM recovery (5.something) and Supreme Rom 5.0
I 've tried cautiously poking around in service mode (*#197328640#). What's most concerning is that the LTE debug screen shows all blank values. Does this mean that the LTE hardware is dead or is it worth me flashing a different ROM / MODEM?
Thanks in advance.

Hi all,
I recently bought an unlocked international version of samsung galaxy S GT-i9000. I was able to use it with at&t sim card quite happily till now. Even the 3g worked on it. But from yesterday the at&t service keeps disconnecting after using for few hours. The network bars at the top right disappear and a blue disconnected sign appears. I cannot make a call or receive a call till I reboot my phone. In settings->about phone I see that the "Service" shows "Not in Service". When I reboot it gets back to "In Service".
Did anyone face this problem before? Is there any solution for it? My unlocked phone boots with T-mobile preset settings - is this problem because of that?\
Someone please help.
I've been using one on AT&T for quite a while without issue.
Ok. Thats encouraging. Did you change the software on it - like rooting or flashing other ROMS or still using the original touchwiz?
I donno why I am getting this error now..it worked fine last week.

I've flash several roms without issue.
Did you install anything recently before the problems occurred?
I just installed a Yahoo mail application and some online radios yesterday. Nothing on the software side like rooting or flashing. I am still using the samsung touchwiz that came with the device.
Looks like that yahoo mail app is the cause of the problem. Deleted that app 1 day back, and it seems to work smoothly for now without any disconnections. Thanks for pointing out to look at newly installed apps.
did you buy I9000 or I9000M ?
I9000 runs on 900/1900/2100
AT&T runs on 850/1900
I9000M runs on 850/1900/2100

Doesn't really matter I had stock/euro i9000and had no disconnects.. although sometimes I only got edge when there was no 850 3g. I now have i9000m and still get no disconnects.. and yes I am on at&t.

I bought I9000 (not the M version). I am able to get the 3g HSDPA with 1900 frequency. I verified it online before buying the piece that 3g would run on one of the frequencies. The problem I had earlier was not with the 3g network, but with the actual cell phone signal which enables to make calls.

I had this problem for a while after I flashed one of the firmwares.. the fix i think i used was to change the settings on the phone from KOR to BMC.. I forget how to do this..
it was one of the *#1234#* type codes.. Anyone remember?
I guess I was early in thinking everything is alright. The problem started again- it gets disconnected once in a while and I have to restart the mobile. Hey dapoktan, can you please remember what you did earlier to get rid of it? If we change the firmware does it help? I am waiting for samsung's android 2.2 update, hope they at least release it by Nov 11th (as mentioned in one website)

Thanks every one for your suggestions.
Before applying nailer's suggestions, I just saw I could update the firmware to froyo by doing a registry hack in kies http://forum.xda-developers.com/wiki/index.php?title=Samsung_Galaxy_S_Series#Installing_firmware_for_different_country. So just gave it a try and currently got froyo.
Have been using froyo since yesterday and no recurrence of the problem till now. I also successfully rooted the device following http://samsunggalaxysforums.com/showthread.php/2384-Rooting-FroYo-2.2 and applied Ryanza's lagfix 2.0 available in market. Looks fine for now and the phone runs excellently smooth.
im using my SGN4 in a brazilian carrier, and everything was working perfectly till from nowhere the phone lost connection from network.
I was unable to make phone calls , but strangely my 4g connection was on i could browse on the web normally. How this is possible? I popped out the sim card and tried in another phone, it worked normally. I also tried another carrier on SGN4, i was ok too. Anyone have an idea what is going on?
factory reset, problem persists, i have data connection, but cant make phone calls.
Is the phone unlocked. Yes I have to ask.
BAD ASS NOTE 4
Yes it is as I told I was using it with my Brazilian SIM card
Is their anyway to check if it still unlocked. I know some people said when they unlocked it was a temp unlock. Did you check APN to make sure they set right for that carrier
BAD ASS NOTE 4
hey guys, im back to this post because the problem persists.
Here is the scenario:
I bought the phone from a Swappa Seller. Phone is t-mobile branded and was in the box, Brand new.
http://swappa.com/listing/ZPB505/view
Brand New Samsung Galaxy Note 4 SM-N910T White ( UNLOCKED) 32GB
Phone is brand new in its original box. The phone has never been used. All Accessories are still sealed in plastic - The phone model is SM-N910T. This is a great deal on a BRAND new - NEVER USED phone!
This phone is guaranteed to work with AT&T. There is no regional lock whatsoever

Can anybody tell me why a T-mobile unlocked phone won't work with T-mobile?
I used the phone on my carrier and it was flawless. Everything was fine till suddenly i lost phone signal. It always show "NO SERVICE" message now, but strangely I still have 4G Connection. I can use the phone to navigate, not to make phone calls.
So I swapped carriers, and the phone was working ok, phone calls, data connection.... then the thing happened again: no service, but i have 4g LTE connection.
Inserted a third sim card, from another carrier. Phone is fine, workin as it should! But this is not my main sim card and i would like it very much to work with ANY carrier. Do you guys have any idea what the problem is? Factory reset did not work at all. For the others sim cards, it recognize the network for a second and then "no service". How can i have data connection if there is "no service"?
Im really desperate because i payed a lot for this note 4... Maybe if i root the phone and flash another ROM?
help please!
Is that possible that previous owner reported is lost and now imei is blocked? Your carrier may participate in that program.

thank you im going to check with my carrier.

Sorry to revive this old thread, but has anybody figured this out?
I too have data with No Service (no voice) when roaming to the USA from Mexico (Telcel). My Note 4 was purchased on T-Mobile USA (contract free) but got it unlocked by gsmunlockers.
Everything was perfect until I got my Note 4 upgraded to 5.1.1 rooted. I have tried several other ROMS and Basebands with no avail.
Any ideas?
Cheers!
I have a T-Mobile ( SM-N910F). The only Roms which work on my phone are the international Roms. They all have 2 small problems. Booting my phone with WiFi on gives my phone a factory reset warning which turns the Wi-Fi off, nothing else. I can turn it back on our avoid this happening by switching WiFi off before rebooting. The second problem is fingerprint scanner not working. It gives an error message. It's not important because I have never used it.
I'm asking a different question though. Is my phone a T-Mobile phone or a SM-N910F international phone? I can use ONLY a T-Mobile recovery but can I ONLY flash Roms from the international section.
I'd be very grateful for any words of wisdom!
Last question, why aren't there any T-Mobile SM-N910F Roms in the Galaxy note 4 T-Mobile forums?
My wife sat her old Galaxy phone down at a big event we went to... it's gone. So I was looking for a new phone and found an S4 Active from AT&T for really cheap. I talked to T-Mobile and they assured me we would be able to get everything working easily.
So I bought it. Got it unlocked through AT&T. Plugged in my wifes new sim and boom - we're up and running. I changed the APN stuff - the network is T-Mobile and all settings work. She gets talk, text, text pictures, etc. I can get on the internet etc. Problem is we're in a place that has weak LTE and very good Edge. My Note 3 from T-Mobile gets perfect 4G and switches between that and a couple bars of LTE from time to time.
This phone gets weak LTE but then switches to Edge to get a better connection.
Yes I've tried the guides to get the 4G radio working (galaxys4root.com/galaxy-s4-tutorials/how-to-enable-t-mobile-hspa-aws-bands-on-att-galaxy-s4-sgh-i337sgh-i337 etc etc) and I even tried following a guide in here that has me flash the modem back to MF1 or whatever it is through ODEN - that just hung on "Setup Connection" and never did anything.
Look - I know the S4 Active is beginning to get a bit old but it's still a really nice phone and it works great. It's more than my wife needs but we need it to get 4G where we're located. Is there an updated way to get this done? Root and custom ROM? New way to fix the radio? Trust me I've searched all over and haven't found it so I thought I would ask. Maybe I'm just searching for the wrong thing but I need help as to how to do this now - not from posts 2 years ago.
AT&T Galaxy S4 Active SGH-I537
Android Version 4.4.2
Baseband Version I537UCUCNE3
Kernal Version 3.4.0-987011
Anything else you would need to know to help out? I'm at the point where my good deal just isn't a good deal anymore and I'm starting to look at T-Mobile phones instead of unlocked ones. Frustrated. =-(
Sorry if this has already been posted, I try to search as much as possible before making a new thread.
New N910T owner here, upgraded from N900T but got it second-hand from someone who I assume used JTAG to repair the IMEI. Haven't been able to get LTE at all, no matter what ROM I'm using. (CM based ROMs display H/H+, TW based ROMs display 4G) I odin'd by using the latest NK4 full firmware (found here) and still no avail.
I don't have an old sim card so I ruled that out. I used it with my old N900T and it gets LTE here no problem. For some reason this phone just will NOT connect to LTE. Trying to find a network will lead to a 5-15 minute search eventually leading to "No service."
Attached is a picture of the ServiceMode menu. Not sure what other screenshots or information I need but I'd be willing to provide anything if it can help diagnose my problem. (If it IS a JTAG issue I'm screwed, the person who I got the phone from was shady to begin with, couldn't say no to such a low priced Note 4 though.)
Currently running NK4 on Hyperdrive ROM RLS3 with stock kernel.
Fixed by going into *#0808#, selecting DM + MODEM + ADB and then used QPST/QXDM to fix the target port.
same issue
I was wondering if any fixed the issue, I'm getting the same issue..
Can you be more detailed?
I'm having the same issues a ls the first post diacribes. I bought a phone finding out the one I number was changed, well the phone register but I have issues connecting to the network, and I can't connect to the 4G lte. The second post states that something need to updated but no instructions.

That doesn't work for my phone, had tried it and no go.
I was wondering how you fix your phone port just like in post 2
I know this is an old post, but did you ever get it resolve?
Hi member Ohmygaa. Accidentally I found your post here and I found it very interesting since I have exactly the same problems with my note 4 tmobile sm-n910t as you described. My phone which I bought on ebay shows no lte only 4g doesn't matter what rom I'm using. Even though Internet shows 4g but it works very slow, can't practically download anything, even websites don't work. Searching for signal every 20 minutes so I'm practically unable to use it. The imei *#06# is different than that on the sticker under battery. So my question is could you be more specific with this fixing of target port ,please? I could try your method maybe it would help to fix my phone? Best regards from NY
