The oneplus support is s**t. I emailed them about this problem, they keep saying to hard reset the phone or contact the provider for the correct apn settings (already tried everything, but they don't seem to understand this).

If this problem isn't solved with the Android Oreo, I think I'm forced to sell the phone. The problem is that I don't know what to get, I don't want another Oneplus phone after this experience.
[OnePlus 5 Questions & Answers] yz999zz:
The current Oreo beta seems to have the same issue....

It's interesting to know if also OP 5T has got the issue as well.
[OnePlus 5 Questions & Answers] Axelguitt:
For your information, I just opened a subject on the oneplus 5T Question and Answer forum "Is 3G data connection working corectly on the oneplus 5T". Maybe they have the same issue.

---------- Post added at 02:53 PM ---------- Previous post was at 02:39 PM ----------

I tested this and I selected "Europe", but it doesn't help.

edit : I might actually work. I'll need to test more, then I'll report.

edit2 : after more testing I am almost sure it works, see my next post

Kicked off my own thread without searching

https://xdaforums.com/oneplus-5/help/radio-baseband-flashing-t3708692

Have noticed that since installing the latest lightening that I've began to get 4G+ back, never had a problem with lower speeds ie: 3G/H

I've gone from 150Mb+ on my HTC 10 with the same card to 50Mb average on my 1+5.

I've asked in my thread about baseband, kernel, firmware, there is a very real chance that beyond the initial set up config ie: APN, Preferred network type, APN type, Network selection, VOLTE On / Off that this could be the fix to our problems.

Either that or the network chips used are a bit crap and Oneplus have cut another corner.

I also have issues with texts not sending at times? Whether that's related or not i'm not sure.
[OnePlus 5 Questions & Answers] icreative:
I do this, all okey now

type *#*#4636#*#* in dialer

then go to Phone information

in the top right menu select "Select Radio Band"

select for your location and its done.
[OnePlus 5 Questions & Answers] reneftw:
Yeap, doesn't help me either.
[OnePlus 5 Questions & Answers] Axelguitt:
Awesome !

I did more testing : I selected my region "Europe" then I did a test during the all afternoon.

I still have high ping when I put the screen on, but as soon as I try to load a webpage or anything else that needs data, the ping is back to normal and it works perfectly! :good: In fact, this is normal behavior, like described by oneplus : when you don't use H+, it goes in a power save mode and when you use it, it wakes up.

This is really amazing : during all the test I did not experience data disconnection like I used to experience before ! :good: I don't have the problem with the loading of webpages anymore. In fact, H+ is totally usable now thanks to you so much. I was able to do voip calls, watch youtube, stream music without interruption connected to H+.

I need to continue testing but I really hope that this is the fix we have been waiting for! If more person confirm, I'll inform oneplus about it.
[OnePlus 5 Questions & Answers] yz999zz:
Thanks for your report, does it survive at reboot or do you have to apply this setting everytime?
[OnePlus 5 Questions & Answers] yz999zz:
This doesn't solve for me, I Tried now, but the issue is still present, see the attachment.
[OnePlus 5 Questions & Answers] Axelguitt:
I rebooted and the fix doesn't survive.

Then I reapplied the fix : it doesn't work.

Then I messed around, selected different radio band and then back to europe (where I live) and then it works again.

Conclusion : if the fix doesn't work for you, keep trying by selecting differents radio bands then the correct band again, it will probably work.

Other thing, the fix survive when you put plane mode off then on.

Do you experience the same thing?
[OnePlus 5 Questions & Answers] yz999zz:
I will try what you suggested and I will report back. Thank you.
[OnePlus 5 Questions & Answers] yz999zz:
Update: actually it seems a lot better!

I will take a couple of days to check if the issue is gone.
[OnePlus 5 Questions & Answers] yz999zz:
Update2: unfortunately the issue is still present (see attachments). This problem MUST be resolved by Oneplus (but I don't think they will).
[OnePlus 5 Questions & Answers] dlads:
Does your normal signal drop and then go back up quite often?
[OnePlus 5 Questions & Answers] zelendel:
The issue is that 1+ uses subpar chips and antenna software. They also skipped paying some of the licensing fees so they had to use alot of outdated code for their modems. IT si the same with most Chinese OEM as they refuse to pay for the licenses.

I didn't notice it, but I noticed that sometimes during a call my counterpart suddenly don't hear me anymore so I have to hangup and make another call.

Hmm.. On second leaked oreo beta i changed my radio band to Europe (Living in Finland) and after that. I can't find 3g network anymore. Only EDGE available. Tried every band in the list and some of those didn't connect to network at all and rest were on Edge. Does anyone know how can i "reset" my network settings to get atleast unstable H+ back again, or fix this another way? :)
[OnePlus 5 Questions & Answers] dlads:
Would changing the firmware / modem, or just the modem make any difference to this?

[OnePlus 5 Questions & Answers] Axelguitt:
Have you tried a reboot?
[OnePlus 5 Questions & Answers] Vika__:
Yes. And when i go to setting and try manually change operator i can find 2 other ISP's 3g networks but my ISP is only 2g
[OnePlus 5 Questions & Answers] Axelguitt:
Strange...

Have you tried to go to SIM settings then put in 2g only mode then in 2g/3g/4g mode back?
[OnePlus 5 Questions & Answers] Vika__:
Yes indeed it is strange. Yes, i have tried those, wiped cache, dalvik-cache. Made few reboots. reseted APN settings. I'm soon running out of ideas and i have to try re installing
[OnePlus 5 Questions & Answers] Spider-Vice:
Interestingly for me the issue seems to be fixed (or at the very least improved) on Open Beta 1. Using H+ right now with no issue at all. Vodafone provider in Portugal.
[OnePlus 5 Questions & Answers] Vika__:
Wiped system, cache and dalvik-cache and then flashed leaked beta 2 but still same issue. I'm sure i'm in h+ coverage
[OnePlus 5 Questions & Answers] Spider-Vice:
Okay, yeah so it still freaks out in some areas even with full signal but not everywhere. Makes me be convinced it's a band issue, I.e different bands are unstable. I used H+ for like an hour fully stable then reached another area that had H+ (also full signal) and it was bugged.
[OnePlus 5 Questions & Answers] Axelguitt:
Yes, a few post later I was saying that the *#*#4636#*#* trick worked during a whole afternoon but in fact I remember that I was using my phone in an aera I don't usually go.

For the moment the best solution that works for me is to use my flow "3G/H+ fix - Oneplus 5 only" with the app "automate".
[OnePlus 5 Questions & Answers] yz999zz:
I Agree, in fact, I experience the problem all the time in the same areas
[OnePlus 5 Questions & Answers] hanhav:
I had this problem too. I upgraded to 4G/LTE-network and of course that solved the problem.

I had the problem usually in the same spot, at my workplace.

My operator told me that there were some problems in the cell but not enough for them to investigate.

I also checked the APN settings many times and thet were correct.

I sent my OP5 to repair and they changed the motherboard.

For a few days it seemed that the problem was solved but after that it was the same as before. Connection got very slow and only reconnecting helped.
[OnePlus 5 Questions & Answers] cirillo30:
with oreo build, there are some improvements?
[OnePlus 5 Questions & Answers] localbus:
I have the same issue with 1 of my telco here.... others are ok..... H+ problem... the data connection will goes 'no data' for awhile... then back again.... as usual... telco say no issue cos other phone is working... OP says no issue as other network is working... :(
[OnePlus 5 Questions & Answers] yz999zz:

I'm going to wait till it's official and has a custom ROM.
[OnePlus 5 Questions & Answers] muimui725:
Can you guys provide which ROM are you using? I am using the nomilit 4.4. I also ordered an OnePlus 5T which uses stock ROM without any issue
[OnePlus 5 Questions & Answers] yz999zz:
Did you try to use OP 5T in H+ mode (disabling LTE) for an entire day? No network issues so far?
[OnePlus 5 Questions & Answers] dlads:
Pure fusion, but this issue is the same on any ROM I've flashed.
[OnePlus 5 Questions & Answers] muimui725:
do you guys use adaway? I remove it and the problem solved somehow..
[OnePlus 5 Questions & Answers] dlads:
I do but then I always have. Will try that. I hate adverts.
[OnePlus 5 Questions & Answers] muimui725:
From adaway: AdAway will not work reliable when on Mobile Networks like 3G. You can deactivate that proxy by going to your selected APN (On Android 4: Wireless and networks -> More… -> Mobile Networks -> Access Point Names) and remove the value in the proxy field.

I wonder it is about that.
[OnePlus 5 Questions & Answers] dlads:
I have no proxy, also i don't use 3G, my phone is on LTE / 4G+ 99% of the time.

After those changes i wrote about earlier, i've had less problems with it.

Speeds are up as well as consistency.
[OnePlus 5 Questions & Answers] yz999zz:
I don't use Adaway, but the issue is present. So the cause is not Adaway.

The cause is a bug into the modem firmware.
[OnePlus 5 Questions & Answers] dlads:
Flashed a modem, matching my base, seems to be ok.

How are all of your speeds over 4G
[OnePlus 5 Questions & Answers] yz999zz:
In 4G (LTE) I have no issues at all. The problem is in H+ only.
[OnePlus 5 Questions & Answers] dlads:
No I mean speedwise, my HTC 10 with the same SIM in my house, same room, same day tripled the speed.

The HTC 10

Down: 154Mb (have had more)

Up: 49Mb (average)

Oneplus 5

Down: 55Mb (at best)

Up: 20Mb (at best)

I've changed everything I can thing of and the speeds are still sub standard, so annoying.
[OnePlus 5 Questions & Answers] Spider-Vice:
LTE (says 4G+ here) gives 120-130 Mbps normally.
[OnePlus 5 Questions & Answers] dlads:
No 4G+ and LTE aren't the same thing mate. 4G+ is a lot quicker

I changed operator and I solved the problem

4G IS LTE !

https://de.wikipedia.org/wiki/Next_Generation_Mobile_Networks
[OnePlus 5 Questions & Answers] dlads:
From what i've read and from the speeds i've witnessed you have LTE and you have 4G+ I do not mean 4G, the + makes the difference, on my network it's called double speed, please look it up on your wiki before you post back.

You would be referring to what is names LTE+ which is not what i said and is not the same thing

Some easy to read literature explaining the difference.

https://www.4g.co.uk/news/what-is-4g-plus-ee/
[OnePlus 5 Questions & Answers] Axelguitt:
Let's keep this thread focused, the issue is with 3g h+ only.

LTE ,4g , 4g+, whatever you call it, is working perfectly fine.
[OnePlus 5 Questions & Answers] dlads:
Fair enough, however just so you know, you'll find that the latter of your statement is untrue, by quite some way in fact, the drop in performance between this and my old phone is ridiculous, not only that but I believe that the crap speeds I've witnessed and the topic in this thread are probably closely related.

That being said, and remaining "on topic" beyond changing modem, firmware to something none of us have seen before or some vast alteration in base (Oreo) I really can't see anything changing.

[OnePlus 5 Questions & Answers] Accerty:
Don't worry about it , this is a common problem of user ,
[OnePlus 5 Questions & Answers] ColdKiller93:
For my part I fixed the issue. Had the same problem as all of you dropping internet connection when connected to HSPA+ signal.

What I did was investigating my fathers Moto g5 not having the issue and dialed in *#*#4636#*#* to open up the test menu then just applies the preferred networktype set on his device to mine.

His was set to LTE/CDMA/UMTS (auto). I also switch frequencies in the top menu to Europe as well on mine.

Connection seems to be very stable since I did that. Your results may vary depending on where you live. I live in Germany.

I'm on xXx Rom 4.4 with Android 7.1

I wonder if the original TD-SCDMA setting is the problem. It seems to be used in China only, I wonder if there are less users in China with the issues than outside China. Could be that OnePlus forgot to change it.

Hi. I am using one plus 5T and having the same issue.

1. Connection drops to H+ once I make/receive a phone call. Internet stops working while on call. (Mate 9 works perfectly)

2. There is no VOLTE option. Am sure it is not sim card issue as my Mate 9 works perfect.

So sad. Received the phone 2 days ago ordered from Hong Kong.

Am using Digi in Malaysia.
[OnePlus 5 Questions & Answers] Axelguitt:
Hello,

1 - I have sometime the same issue when I make a call.

2 - volte works only if your phone carrier recognise your oneplus 5T as a volte-capable phone. For marketing reasons, lot of phone carrier doesn't allow volte on some phones and there is nothing to do about it.

Do you experience also the same issue as described in this thread, by this I mean if you use H+ a few minutes on your phone for web browsing, the pages will stop loading after a while until you toogle your data off then on?

Last thing, if you have a problem with your oneplus 5T, I suggest you use your 14 days return and refund period as soon as possible. Because after this period the oneplus support will refuse to take your phone under warranty for connectivity issues even if you prove them that your phone has a defect.
[OnePlus 5 Questions & Answers] sToRm1nG:
I am not convinced that this is actually the problem. With LTE/CDMA/UMTS auto (PRL) I almost never have connectivty for 3G (UMTS / HSPA / HSPA+).

In Switzerland all carriers use WCDMA with FDD for 3G (UMTS / HSPA / HSPA+).

I am now testing LTE/WCDMA without UMTS since this should be covered with WCDMA.

I compared it with my HTC One M7 which is set to GSM/WCDMA/LTE auto. However, this cannot be selected on the OP5...
[OnePlus 5 Questions & Answers] Yousvel:
Thks is the settings that apparently solves my h+ issue

I have been using this settings since 1 day with no issues. Try it and report. LTE/CDMA/UMTS auto didn't solve it for me. But

LTE/TD-SCDMA/UMTS solves it for me.
[OnePlus 5 Questions & Answers] sToRm1nG:
Where are you based? In Switzerland our carriers don't use TD-SCDMA but W-CDMA.

And like [MENTION=5351996]Spider-Vice[/MENTION] already wrote TD-SCDMA seems to be used exclusively in China as an alternative for W-CDMA (https://en.wikipedia.org/wiki/UMTS#TD-SCDMA_(UTRA-TDD_1.28_Mcps_Low_Chip_Rate_(LCR)))

The main question is what exactly is the meaning of UMTS in LTE/TD-SCDMA/UMTS or LTE/CDMA/UMTS.

UMTS should be a mobile cellular system which is either implemented using WCDMA, TD-CDMA or TD-SCDMA as far as I understand it.

As far as I can tell Digicel Haiti (which seems to be your provider) does not have CDMA in use at all (https://en.wikipedia.org/wiki/Digicel#Digicel_Group's_operations), so you should be fine with whatever contains LTE and UMTS.

Hi,

I can confirm that I can't use DATA and Voice simultaneously whether I am on 4G or H+.

When on 4G, signal turns into H+ right after I hit the call button, and no Internet connection.

When on H+, no signal changes when I hit the call button and still no Internet connection.

Internet works well without voice call,whether on 4G or H+
[OnePlus 5 Questions & Answers] Blumdum:
I have a thought which may be a possible solution to this problem

When the screen turns on we have a small delay of the internet connection which may be because the h+/internet module/package/app is in some sort of deep sleep to save power and wakes up and connects the the faster h+ mode

And also we experience some connection losses during normal usage

so here is my thought maybe this module/package/app goes in normal usage unexpectedly in deep sleep because of some power management and therefore we loose the connection

its just a vague conjecture of mine

if this is the culprit maybe its possible to keep this module/package/app active while having the screen on

and again its just a assumption which came to my mind while walking home having connection losses...
[OnePlus 5 Questions & Answers] BFMSAND:
My Point stands, as i just said that 4G is LTE, it doesnt matter if its 4G or 4G+ its both LTE, no matter if one of them is a faster Version of it or not, its still LTE.

You have no idea what you're taking about mate.. they are all different, don't sprout crap like it's the truth. They all offer different speeds..

Are you going to say that they are the same too?

You're both right, lol. 4G is LTE, just like 4G+ is LTE+ or LTE-A(dvanced)

[OnePlus 5 Questions & Answers] BFMSAND:
Before this gets out of Hand, I'll say it one last time 4G IS LTE, please read what i wrote,It doesent matter which 4G, ist all still LTE even when some is faster and some is not, that is FACT.

And now lets get back on Topic as this still does not solve the Problem People here has.

To contribute myself, the most Problems i had where on oos ( even now as i am on oos oreo leak 3 ) where this Problem with h+ is the most notable, the lowest Problem i had where with aosp roms like rr Remix ( had both the unoficial and then the newer unofficial from tushar jain with oos cam ), so i dont know if this has anything to do with Firmware behind it as i hadnt updated my fw when switching to oos in the time beeing.

EDIT: More info:

Phone OP5 - Grey - 64GB Version ( 6GB Ram)

OS: OOS Openbeta / Leak 3 , Oreo 8.0

Country: Austria / Europe

Provider: Drei-Austria (Three , 3 )

currently no LTE contract ( gonna make one soon )

Thats what im trying to say as it indeed is FACT that 4G is LTE, it doesnt matter which one you want (4G,4G+, LTE, LTE-A,.. ) ist all LTE as term behind it.

OFFTOPIC EDIT:

I will Quote you back here as i will not waste any more Posts on this and be off Topic just to be in danger of getting a message from a admin or moderator.

But when you mean 4G+ is not LTE but it is LTE+ then will it be so, still we both are right as i just said that no matter what 4G its still all LTE as the hypernym, i hope you understand now what i meant, if not i will not bother this anymore.

Even though its a bit childish to say "End of Story and I am right", but to each their own..
