Had my P2 a few months now and apart from the notifications not coming through issue it has been great.
Something that has happened know for a while is that I seem to o la connect to H+ and not 4g. Sometimes I do get 4g but very rarely. My wife who is on the same network gets 4g when I don't. I always used to get it at home and work but now. I dont.
If I go I to settings and choose Vodafone 4g instead of automatic it picks it up but after a while I get a error notification saying g no service on the selected network (even though I do have full service), if I put it back on automatic network search then the error message goes but I them go back to H+.
Any ideas?
Thanks
Where are you and do you have a p2a42 or p2c72
i'm on p2c72 stock. It's on 4G all the time. are you on stock?
Depends on where in the world he is p2c72 doesn't have some radio bands commonly used Europe and the America's
Yes,it's probably a frequency band matter of the model of the phone
Yes it seems it doesn't support 800mhz LTE:

And Vodafone uses that frequency so that will be the problem.
The p2a42 does the p2c72 doesn't

I live down in Costa Rica and they recently opened up 3G service which operates at 850 mhz. I upgraded my service but cannot seem to connect. I always just get the E icon and get slow speeds.
I am using the radio 4.49.25.17 and have tried multiple roms. The setup which they told me (and what seems consistent with what I have read) is kolbi3g for the AP and leave the username/pass blank and no proxy.
When I try manually switching the 3g band to 850 in the settings rather than auto I get an error message telling me that "The answering modem has disconnected..."
Does anybody have any ideas of what is happening? It's hard to tell down here if the problem lies on my side or theirs. A lot of people are having various issues but they won't tell me if those issues are similar to mine. They keep telling me "try tomorrow", but I have seen other people whose phones are working a 3g speeds. Is it possible that they have to configure something on their end?
Is this a US phone? I think 3G only works here.
Sorry, I guess I should have mentioned it is a quad band european model and does support 850 mhz.
3G in CR
I have the Touch PRo 2 and am also in Costa Rica and the 3G for this phone is very slow but does work Im not sure if the problem is lying with ICE as I was tol they are still upgrading their lines or if its the phone in general but Im on the unlimited plan and supposed to be getting 1.5mbps and not coming anywhere near that. But I do know that the 3g is working as I have got on the internet with it but is like a 256kb connection.
Its model is T-Mobile_Rhodium unlocked
Will post after I verify this with ICE on Monday

I bought an unlocked Sony Ericsson Xperia Play R800i from Amazon to use with a Straight Talk sims card; however, I'm unable to connect to 3G. The phone only shows an Edge connection. Straight Talk specifies that the phone must operate in 850 and 1900 MHz bands. Here's what the Amazon page says about my phone:
This phone can be paired with 800/850/1800/1900 MHz UMTS/HSPA 3G networks in the United States (as well as 900/2100 MHz 3G networks found around the world, including in Europe and Asia). In areas not served by a 3G network, you'll continue to receive 2G data service via the EDGE network (depending on network compatibility).
I might be wrong, but doesn't that mean it operates under Straight Talks specifications?

i have the same issue but with my carrier offering 3G at 2100 Mhz which is Xperia Play supporting. When searching for carrier it shows me just 2G provider, non 3G. when WCDMA only selected, i lose signal. I am in coverage of 3G and my plan is supporting it.
Could it be hardware issue? i did factory reset but still having this issue. Connections just through EDGE, GPRS or Wifi

I purchased an R800at from Amazon, which, according to that thread, should be able to connect to 3G correctly.
I've unlocked the bootloader, and flashed CM7.2 onto it, and I'm still only getting an EDGE connection. It shows a second connection under the "Network Operators" menu in the mobile settings, which, when I ran the stock ROM, was listed as "3G" but it always defaulted to the "2G" listing.
I live near a large city, and have gotten 3G on other carriers, and even 4G on a friends T-Mobile phone. I think I'm running the T-Mobile based SIM card, because the AT&T APN settings don't work with it, and the SIM came with the T-Mobile settings, it's even labeled in my APN as "Straight Talk T-Mobile" but I still only get EDGE.
I don't know much about straight talk, but is your Sim a 3G one? I had this issue a while back where i could only connect to 2G networks but then went to my carrier's store, told them the problem and they ported my contacts and number to a 3G sim and its worked ever since.
It may also be worth trying to get the APN settings from your service provider to see if this solves the problem.
I have an unlocked R800at (AT&T) that I am using on T-Mobile. Now where I live it shows that people have already reported getting HSPA+ on unlocked AT&T phones.
I have all the correct APN settings, however I always get 2G (Edge). But if i got to:
Wireless Networks
Mobile Network
And select search, for me it will bring up T-Mobile 2G and T-Mobile 3G as options. I select the 3G and it will connet and I will get HSPA+ (download of up to 7mbps, 3-5 up) for anywhere from 30 seconds to 5 minutes, then it reverts back to 2G. Its not a huge deal for me as when I was on VZ I had edge like speeds, but to be honest if I can HSPA+ then i would like to have it but I cannot find a way to get it to stay on 3G. I have used 3G speed tweaks, trying different apn's... nothing. Anyone have any ideas or suggestions?

I'm not entirely sure. I bought it on ebay, it's listed as a T-Mobile SIM card. It was a standard size, that the seller cut to micro. I have to put it in an adapter to use it with the phone.

hi, i have the same problem. r880i, it works well on gsm, totally unstable under wcdma..the "funny"thing is that i can't make calls nor text when it gets no signal(with the yellow triangle at top left),but i have data connection(i can install apps from store,browser youtube facebook works ecc) and i get mm#6 error sometimes(the phone in not stolen or whatever lock). all working well when set to gsm; if set to wcdma/gsm, or wcdma only it does the above mentioned behavior. i've relocked bootloader and repaired with seus and am currently on stock 2.3.4.. any fix or know issues?
Hi
Anyone else get random disconnects from mobile network? My device says H+ has a good signal but can't transfer data. Enabling/disabling flight mode fixes. I believe it's linked to cell handover or LTE <--> WCDMA handover. Does not do it if device is stationary. Sim works fine in my xperia z3, likewise sim from Z3 (different network) has same issues when installed in TAB S.
To complicate things, I have also seen issues with BT tethering, using phone for data transfer when device in this non working state. Again, in/out of flight mode fixes. WiFi works just fine.
Device is latest stock firmware, not rooted because I like OTA, and have no time to fiddle these days.
Just switched it to WCDMA-only for a test tomorrow. I commute same route by train each day.
Really annoying. Afraid tab is headed for fleabay if I can't solve. Beginning to think it's a designed-in Samsung issue. [emoji20]

I am experiencing the same issue with my LTE signal. it says 4g with 2 bars of signal then suddenly the arrows stops so transmission of data also stops then airplane mode sometimes no longer work. i would have to put the device to WCDMA only then back to LTE.. I can force my device to use LTE only bad sadly the signal drops almost 1 minute after connection
Is your device exynos based or snapdragon. There are two variants doing the rounds with the snapdragon only in the US. On exynos based devices, an Intel LTE chipset provides the LTE connectivity. I believe the US version uses the (faster and better) snapdragon due to a lack of LTE band support in the frankenstein exynos/intel solution. I wonder if the intel lte chip does everything or if the exynos is left to do 2g/3g?
I have disabled 4G on my tab s and the random disconnects appear to have stopped. Did not buy a 4G tablet to have to disable 4G to make the ruddy thing usable though!
Device is also very jerky in comparison to my snapdragon based phone. Not enjoyable to use really. Prob due to all the junk (touchwiz) that samsung shove on it. Its a huge shame because I love the design and build of it, as well as the elegant way in which the stock cover attatches. Good hardware let down by very poor software for the most part.
I think i'll give up on it as a bad job, shove it on ebay and buy a Z3 Tablet Compact instead which is snapdragon 801 based.

Hi
Been fiddling with band settings in the service menu in order to solve this issue.
See: http://forum.xda-developers.com/galaxy-tab-s/help/unlock-aws-tab-s-8-4-lte-t2860001
I have disabled the 2G,3G and 4G bands that my network does not use - at least it will save the device from hunting for stuff that it is never going to find. Of course, it will need to be re-enabled when I go abroad.
Will see if it makes any difference. One thing it is useful for is preventing the device switching from LTE to 3G where the LTE signal is marginal, and the 3G signal strong. Just disable the 3G band, and the device is forced to hold onto the LTE signal. Its also useful if you have a tablet and thus find 2G useless. Disable all the 2G bands and the device is prevented from connecting to 2G networks. It will then hold onto that 3G signal as much as possible rather than dropping down to a stronger 2G signal.
Nigel
I have the exynos version of tabS 8.4.. this fooled me when I bought my device since I was hoping for a Snapdragon version.. but too late. I had to live with this.
what I normally use is *#2263# same with my galaxy note3.. I disable the wcdma and gsm. so forcing the device to LTE only. but this problem is that data transmission drops frequently.
when I tried what you said. signal seems to be better.. I'm still testing it out. thanks for this!
*update. same problem but less frequent.. so still crap:crying:
Guys
Possibly related is the S5 DUOS phone is also reporting issues with dropouts on LTE.....users are having to reset or enter Airplane mode to 'reset', could be a common chipset/firmware/modem issue perhaps.
So... I fixed my issue by buying a Sony Xperia Z3 Tab Compact.
Superb device, and so so so much faster than my Tab S + battery lasts much longer. Not had it long, but some initial thoughts here:
http://forum.xda-developers.com/showpost.php?p=56721334&postcount=11
Tab S 8.4 LTE (Exynos version) on fleabay soon!
Rather expensive mistake, and my final Samsung device for a while I think.
Nigel
it's a LTE band problem ; this is how to fix it
hello
first before u do anything , you have to look for the LTE frequencies used by ur provider , for example here in Morocco my provider Orange works on 800Mhz , 1800 Mhz and 2600 Mhz , which i LTE B3 ,B7,B20 .
So , i had to select only those bands only in the service menu (*#0011# : Back Back /UE setting & information/ Setting / Protocol /NAS/Network Control/Band Selection/[1] LTE BAND
All you need to select in the service menu is the Bands used by ur provider to avoid lost of network by ur Tablet when it s switching between bands which causes rebooting everytime .
i hope it works for u , because it works just fine for me
So I'm on WIND with the LG G4 (H812). I have unlimited US roaming with them, and just got back from a roadtrip in the United States. I drove from Toronto, ON to Los Angeles, CA and back (in 2 weeks), and got to test the G4 in over a dozen States.
My data was excruciatingly slow. The icon at the top of my phone said I was connected to 3G (never HSPA+ or 4G), but it felt slower than 2G. I couldn't stream music, couldn't watch YouTube. Websites and the Facebook app barely loaded (and photos never worked). Facebook Messenger and Google Hangouts would send, but again, barely. Sending someone a photo using Messenger usually took 5-10 minutes.
This was the same regardless of what State I was in (over a dozen states).
When choosing what to connect to, it always gave me 4 options:
T-Mobile: WCDMA
AT&T: WCDMA
T-Mobile: GMS
AT&T: GMS
I always got the same speeds, no matter what I connected to.
On my old HTC One (M8) on WIND roaming in the US, I was always able to choose if I wanted to connect to 2G, 3G, or LTE. That's missing on my LG G4. The only options I'm given are:
GSM/WCDMA auto
WCDMA only
GMS only
I tried figuring out more information on my connection and bands. I went to the dailer and entered *#*#4636#*#*
A note would pop up that says "This application does not work on this device." and I couldn't see anything past that. That code doesn't work even now that I'm back in Canada.
I'm heading back to the States in a week, and unsure what to do. Is the problem WIND? All Canadian carriers? H812 Bands? Now that we have root, is there anything I can do to fix/unlock this without switching carriers?

Does your plan also include DATA roaming? 4G, LTE roaming? I think it would require adding an APN? Perhaps the roaming network towers can not authenticate your device, ect?
You can use the play store app LTE Discovery, it can show you what bands it's connecting/trying to connect.
Here compare your 812 to 811 810 bands. http://pdadb.net/index.php?m=pdacomparer&id1=8306&id2=8059&id3=8046

Yes, my plan includes data roaming. I've been with WIND for years, and used my HTC One (M8) on exactly the same plan while roaming in the US, and it worked properly. I reached out to WIND and their response was:
"I believe our roaming agreements cover 3G access while in the US."
Like I said, my M8 worked fine at 3G speeds in the past. It's specifically been the LG G4 that barely worked.
I took my Bell G4 to Italy this summer and got LTE in Rome, hspa otherwise. Worked great, just had to enter the apn myself (which I had to do on my Samsung phones travelling over the years).
Have not tried it in the US.
Im with Rogers and had no issues with roaming. I think it chooses AT&T in the states by default.
If I recall correctly WIND doesn't have the LTE band on the G4s. It's missing something. Although based on what youre describing it's like you're on EDGE (2G)
Howdy.
For quite some time i've found my phone to download quite slow on LTE+ Mobile Network.
LTE+ or LTE Advanced is nothing different than LTE with Carrier Aggregation. This means instead of using a single LTE Stream it will use 2 LTE streams at the same time.
Now my observation with LTE+ is that i get about 5mbps in Speedtest app, while using only one LTE Stream i get about 20-40mbps. Which is like.... utterly nonesene.
So, where does this come from?
A: Because i have a 709 Taiwan device with Taiwan Modem it's not working here in Europe
B: My Antenna is broken.
I've had the exact same behaviour on Stock Rom, LOS and AOSP based ROMs. So i don't think it's a software issue. (and yeah, i did RUU in between)
I've tested this over 6 months in 5 different cities with different ROM/Basebands from 1.92.709.1 onwards to 2.41.709.7 Similar results every time.
I've Changed Sim card from SALT to Swisscom and had LTE+ signal, same issue. 5-10mbps maximum.
Now then. Anyone here has tests of LTE and LTE+ and has a similar issue? Or is it working flawless for you guys?
How can you tell you are on CA?

Because words are nice but screenshots are better... Here some screens from the root app Network Guru WHILE using speedtest in the background!
Normal:
And with LTE+ aka 2xCA
Just in case you're curious, here are some Screens from the Swisscom Network, as you can see they sue EARFCN 6300 and 1301 instead of 6400 and 1601 as Salt does.

Hi small issue actually. You need to set 4g apn setting to your mobile.you may refer to your telco or google setting 4g for your courier. Like me using celcom malaysia also do manual setting 4g.auto apn setting only 3g.
I have also had this issue on my HTC 10. When I was seeing LTE +, I expected even faster speeds, however the opposite happened. Fortunately many places don't have LTE + so this is not affecting most of the times.
