I used to use a Galaxy S3 and at home I always got a data signal showing H+
I recently switched to a Note 3 and now at home my data signal never goes above E and it stupidly slow.
Voice signal strength on the other hand is always full.
Is anyone else experiencing a low data signal like this?
Tried a different SIMcard? These problems usually result from an old SIM in a new phone. Those two don't mix very well.

I don't have another sim to try, and everyone i know is on a different supplier so using one of theirs would be pointless, and my supplier charges for a sim change so really a no go unless i know for a fact that's the problem.
Really? Even with problems? Oh, right, HI is KPN... Of course they do.
Different providers shouldn't be an issue, there's no SIMlock in the EU. (thank you Kroes.). Any provider from the EU should work without issue. If one of theirs works, it's not the phone.
Alternatively, you could go to a shop and use one of their test SIMs.
Also, does the connection go above EDGE when you're somewhere else? Or does it stay slow everywhere?
Yea I also noticed this on my device.
Im on stock deodexed rom ( NC2 by @_alexndr ) and my reception also is worse than on my previous S3.
Im constantly playing with the idea to flash another KitKat modem.
Tbh I tried once via odin but after restart nothing has changed in my about phone while odin said success?!

I tried a different stock rom and it made no difference at all.
I also remembered that my netbook has it's own sim card on a different provider so I put that in and got the exact same result so it's definitely the phone and not the network
I did this to my note 3. Dial *#2263# then select lte/wcdma only. Then menu > end.

that code does not work for me
@Larkspeed
maybe I should mention that I use the Spigen Neo Hybrid case on my Note 3 whereas the S3 was "naked".
This could make a difference but apart from that I dont get why the reception is so bad in comparisson to my S3.
I've got some problems with mobile data on my Note 4. I've bought unbranded phone in shop unrelated to any mobile provider. It's Snapdragon version (N910F).
I've got prepaid service, without LTE available (if that's important). The problem is that every now and then mobile data simply stops. There is still H or H+ sign in notification bar, and upload arrow blinks. but when i try to open web page or send message through viber, wattsup it acts like there is no network. Then i have to wait for about 30 seconds or manually turn mobile data off and then on again for internet to start working again.
I've tried changing APN settings, changing network type, but the problem is still there.
I've read some similar issues with Note 3 and SGS5 users, and some problems with modem versions, but i couldn't find anything from note 4 users
And this problem is very frustrating on phone like Note 4
Is there anything else i could try?
Mate i have exact same problem
I don't know if this is relevant, if your apn settings has a proxy and port values, try to delete it and let the proxy and port be blank. I had issues previously with data getting stuck while using proxy setting.

I also loose data signal and on calls people cant hear me properly.. doesny always happen. Ill try thanks
Also experiencing this with Tmobile UK.
Also have this exact same problem with the unbranded SM-N910H, H+ but no internet all of a sudden. I also sometimes lose the whole signal (Emergency Calls Only) so I have to reboot or turn airplane mode off and on to get it working again. I asked some people and they told me it's a coverage problem with the network provider. IDK if it's true.
No ahmadmob its the phone although i have n910u i have exact same problems as u!! I thinks its modem hopefully gets solved soon im in Australia using prepaid only 3g/h+

Glad it's not a carrier specific issue.
Guess I'll wait for an official fix or for other radios to become available.
I rang samsung australia few weeks ago and they had no idea than again when do they ever!? Lol so looks like we will have to wait buddy
Some common suggestions:
1- Swap the SIM card into another phone to see if the problem persists?
2- If the problem is due to Note 4, you may need to update your firmware/baseband to the latest one (if one is available, or you have to wait until Samsung release it), or try another firmware (from another model) or custom ROM.
Tried already mate sims fine updated reflashed stock rom and still same problem.. hopedully update comes soon
I just tried sim card from another carrier, and for now, everything looks fine.
I'll go ask for a new sim from my carrier, or switch my number to another one.
Sorry for digging, didn't want to make a new topic.
I'm here with the same problem. Did any of you find solution for it (other than switching to different carrier). I'm on Play in Poland and i find mobile data problematic mostly in roaming (free roaming with every carrier in Poland). For example on t-mobile or plus i find my up arrow constatnly blinking and H switching to H+ and again. Problem is even worse with 2 or less signal bars. I'm thinking of changing sim cars to new one, but on my note 2 everything works perfectly fine.
I thought I noticed a slight improvement after the final KitKat update, may have been a placebo effect though.
In general it's still bad, much worse than my HTC M7, same network, same location etc. It seems to be particularly bad when travelling at speed e.g. on the train I get full bars but only 1 arrow flickering.
Upgraded to Lollipop a couple of days ago and finally rooted, doubt this will make a difference but will be able to report during my commute tomorrow.
In summary: The HSDPA modem on my phone is rubbish.
P.S. Previous phones I've owned came with options for different modems, I'd often flash these to improve performance, where are they for the Note 4?
I think they're not available yet, at least on lollipop...
Mine is completely fixed after a few updates i get 4g+ here excellent reception

Could tell more how did you fix your problem?
All fixed!
I can confirm that after the lollipop 5.0.1 update on my SM-N910H all my mobile data problems/mobile network drop outs are solved!. 3 days without any problems now.
Edit: maybe it had something to do with Radio and it got fixed after it got updated along with the lollipop update package?
Guys, here in my country Bulgaria, many of us owners of SGN4 have the same issue and wilth Lollipop also. I have noticed that with KitKat the problem was more frequent than Lollipop but it is still there. We have tried Polish Lollipop and now the official Bulgarian Lollipop but the problem still exists. I hope somebody will tell me which ROM you have installed (oficial) so I could share it with my fellow citizens. Thank!
I recently bought Samsung S5 G900F from a friend which updated it to latest lolipop 5.0 software, and after that wifi stoped working.
It was never rooted or etc. When i try to turn on wi fi i press button for turning on freezes and it doesn't show any wifi network. By my friends words it started after updating to lolipop. First i downloaded and flashed two 4.4.2 from sammobile and i there's no difference at all.... Second thing i found thread with latest modem on xda and nothing at all.
The only thing that helps for short while is from unkown reasons when i switch SIM cards it starts working but speeds are 200,300kb/s and signal is very low. And from some secret code went to wifi settings and turned off battery saving mode, it helped to now more often it works but for short while and slow speeds.
I don't have any ideas, what to do with it all sings show that it is software issue. Thanks in advance on replies
This erro my phone not my eny solution.?
Hi
I bought my Samsung S7 Edge G935F a year ago from Samsung uk. It is factory unlocked etc.
Recently I upgraded to nougat 7.0 (OTA). it is working well. However, i discovered an issue with bluetooth and connection to my BMW 535D E60.
on version 6.xx the phone was working with the car and it was connecting.
Now with 7 it does not want to connect to the car. The phone finds the car bluetooth, but does not proceed with the connection. (it accepts the pin etc too )
So i thought it might be the bluetooth in my car... I tried iphone 6, Sony Z5 Premium running nougat. they both work fine with the car. So its phone related.
Now to make matters worse. I though maybe i should re-flash the device using ODIN and firmware downloaded from sam mobile.
So i downloaded the XEU flashed the rom, and now in my settings i have extra menus etc.
G935FXXU1DQB7_G935FXEU1DQB1_XEU
"T Roaming"
"Service Provider" .>>>> Shows GIGA LTE, KT Twophone service...
I did some resarech and KT is pointing to Korea?
I have then downloaded the following ROM
G935FXXU1DPLT_G935FOXA1DPLT_BTU
This rom did not change the menu much. The GIGA LTE, KT Twophone is still showing up.
On top of that If my on screen keyboard has autocorrect turned on.. then i cannot type any full words. I start typing 1st letter, then 2nd letter, BUT 2nd letter overwrites the 1st letter and does not move to position 2...
it on 1st space... I have to press SPACEBAR and then backspace to type the 2nd letter and so on for 3rd an 4th and...... I turn off autocorrect it works.
can someone point out to me WHICH firmware ROM i should be using ( STOCK) to flash my phone with ODIN? A link would be great.

I have been dealing with this same problem for 2 weeks now trying to get a fix for it. My problem is almost identical except for the fact that i cant connect to any networks and it now says invalid sim card. It was unlocked previously so idk why it would say invalid sim card. i can reflash the firmware and it makes the KT giga lte twophone references in settings go away but it also gets rid of mobile networks menu in general. @autoprime mentioned to me that you could go into iothiddenmenu and then as long as you havent backed up your nv items that have the currently bad settings (korean stuff) than you can do an NV restore to fix this issue but for some reason i cant even get into IoTHiddenMenu for whatever reason. If anyone can help with this issue that would be awesome because im stuck using an old iphone4 until then and its getting rather annoying.
Hi!
My device is Samsung Galaxy Note 3 N9007 (Australia version OPS) and I've recently flashed 'new' firmware from sammobile.com to update my modem, bootloader etc. Everything went fine but problem with 3G/H/H+ occured. From some threads here and some from reddit I concluded that this phenomenon with switching between those three is called Fast Dormancy and that isn't bad thing and it should work great. BUT. I doesn't work at all. While switching between 3G and H+ there is no mobile data transfer which is so annoying. On H+ it works great, but when switched to 3G it doesn't. I live in Poland not Australia so I have diffrent bands for 3g etc but on old modem everything was ok, Fast dormancy didn't occured. So I restored old modem and restore old ROM which is MagmaNX but this problem still occured! Even on old modem. So I've done some research again I tried to disable Fast Dormancy with root, I've tried to disable it through service codes 9900 9090 4636 301279. Nothing helped. Best thing is that on LTE it works great, but with LTE on I can see my battery crying.
So I'm asking you, dear Users of xda Developers ( because you can do miracles ) IS there any posibility to get it back going ?
PS. I know its strange that I have model N9007 rather than N9005 but it happend and I couldn't do anything about it (I've got tricked on ebay, sadly)
Here are few screenshots about my phone. If you want some more info just let me know. @bump
I have found a soulution.
