[Q] Data connectivity issues - Slow 3G/H - One (M7) Q&A, Help & Troubleshooting

Trying to work out whether I have an issue with my One, my sim card or the network...
WHenever I use wifi I have no issues with connectivity and data speeds. However, when I am using 3G/H (I don't have LTE/4G) the speeds are painfully slow and often nothing loads. This happens both in my place of work (Central London) and at home (North West London). I'm not sure whether it has always affected the phone, I think so. I am on T-mobile/EE and the issue doesn't change whether I have one bar of signal or five bars of signal. I downloaded the SpeedTest app to check what was happening and it seems that it can't even do the initial 'ping' to the server.
I plan on checking another sim in my phone, and my sim in another phone to try and narrow down the possible errors but was wondering whether anyone here has had any similar issues. I'm currently on my fourth One (1 and 3 - misaligned screens, 2 - dead pixels) and I am really hoping that I don't need to get this one repaired/replaced now. Hopefully someone has some good news!
Thanks in advance!

Problem with internet Communication

Hello All,
I have a problem with my kaiser, it started i think 2 weeks ago. I have vodafone (netherlands) with a data connection account (hsdpa). Now is the problem that i can't use umts (3g) or hspda. The only thing i can use is gprs. It looks like the modem or something is broken. But that is a kind of weird because (if i understand correctly) its al the same chip (wifi and so on). When i open internet explorer it begins to connect a gprs, 3g data connection. But it can't connect, than you can see a X by the synchronisation arrows (on the top of the screen). And after a few secconds it comes with a message that with the current settings there can't be a data connection. But if seen other messages as well ( the modem on the other side disconnected the connection) The weird thing is that i tried my sim card in my friends kaiser there it works fine, so it have to be my kaiser.
Ok what i tried:
I have a dutch htc kaiser (not vodafone branded or anything)
I use the latest dutty rom, but i tried the orriginal rom and different roms to see if the problem was the rom or something.
When i let the 3g mode on i can see that the phone finds a 3g connection (to call over umts).
Is there any program or tool or something so i can test the modem?
Or does anyone know a sollution for me, i will be very greatfull!!
Ok i tried a other radio to, maybe this was the problem. But it didn't, at this moment i have the default htc dutch rom (who was on the phone when i got it). I searched the net for the same problems, what i found was that this error could be happening when you have your wifi connection open, but i have wifi disabled. The phone is still receiving a 3G connection, but after a few secconds the 3G icon is gone and the failed synchronisation icon (two arrows with an X) is visible. than you can see that the phone is reconnecting. and then if i want to connect to the internet the same story as above is happening.
When i search internet i couldn't find an tool to test the chip/modem.
Because i have it spl unlocked i can't return it for rma, is it posible to restore the default spl?
Hi,
unfortunately I have the same problem with my Kaiser. I have an unbranded German version and it worked fine with all bands (GPRS, EDGE, UMTS(3G) and HSDPA) but since two weeks ago its only working with GPRS and EDGE mode. I have to change band-selection from AUTO to GSM in order to make or receive any calls.
I didn't do any ROM flashing, everything remains the same as the device was shipped.
I assume, that something is damaged but I have no idea how it could happen or how I can find out exactly what is causing the problem.
Since there is still warranty I'll return my Kaiser soon.
seems to be a widening problem
hi,
it seems many have the same issue, see my other posts for linkage to some other threads on it...no solution yet as far as I can tell.
rich
p.s. moderators any chance to link these threads and make a sticky?
ok, thanks for your reply. I've allready found another thread for that issue. But im still uncertain if its a bug in my device or a combination of a bug with a provider specific (Tmob Germany) problem or if its only the provider to blame for??
Chris
I have a slightly different problem. I don't have 3G in my area but only EDGE. Now the problem is that I cannot get speeds higher than about 80 kbs with EDGE.
Now when I put the same SIM in my Touch I can get speeds upto 200 kbs. So obviously this is not a problem of my service provider but rather something wrong with the device.
I have repeated the trial by swapping SIMs a number of times but with similar results all the time. Really don't know of a solution. Will appreciate any help.
haven't seen the edge problem
hi,
my edge speeds seem to vary more by location...I measure up to 200+kbs but have seen it go much lower too. there is a location where I can still get 3G working and i measured up to 1.7mbs for downloading! At my home location it is sporadic edge only and I can't even always get to speakeasy.com to test it, sometimes the speedtest says its not licensed..switching to wifi and it works. My guess is some needed ports are getting blocked by at&t at times..because sometimes it works. I brought all this up with at&t..they are taking some charges off this month and switched me to a cheaper plan too...so they at least seem to care even if they can't quite fix things yet.

[Q] 3G- no data, but GPRS, Edge & HSDPA ok?

I've had this problem with my Nexus One for as long as I could remember, but kinda ignored it - thought perhaps a new radio would fix it, or a new ROM...
But no, it still bugs me.
Basically, if the phone is on 'normal' 3G, I cannot receive any data. It just gets no connection. If I have HSDPA, or GPRS or EDGE - it all works fine.
But 3G? Nothing. And its EVERY time.
Travelling on the train every day, HSDPA isn't stable, so it often drops to 3G, but then it drops dead. I have to restrict the phone to 2G if I want to check things reliably.
I've tried every radio from every country from the original to the latest 5.12 leak.. yes, speeds increase, HSDPA engages more often, but as soon as I'm on normal 3G: Dead.
And I've tried all ROMs (original, MCR, Cyanogen, Desire, MIUI) - same.
Any build.prop tweaks I could find... same.
Now, I remember talks about this when the Nexus came out originally - but there doesn't seem to be any threads about it now, so do I just have a faulty Nexus One that I've put up with since Christmas last year?
Or have I missed something blatantly obvious that every else did to fix this problem?
Any help gratefully received
Pardon my grammar and spelling I'm typing from my phone without swype and its annoying. I had a similar problem. When on 3g I'd miss calls texts, etc...I had my boss call in my face and my phone didn't ring. It got so frustrating I turned off 3g for several months. Too make a long story short ....all those 3g problems went away when I 2.2 came out on xda I put a new radio and rom on. I can't tell u if it was the radio, 2.2, or if tmo had simply added new towers or improved signals from tmobile.
I'd call tmo see how your area looks and if there's any new towers.
I've been on 2.2.1, and 2.1, 2.2, and used all the radios that have been released.
All the same.
I'm in the UK and on Orange, and I have spoken, well, tried to speak to my network about it a couple of times, saying the fact that I've had this issue in the past with my HTC Hero, and I've tried every software update, radio, etc, but because the Nexus One isn't an Orange handset they blame that, Android, or the signal in my area. Yet, I can't believe its just 'Android', and it can't be all signal where-ever I go, so perhaps my phone does have a fault? I don't know!!
The common denominator between this and my Hero is the SIM card.. but convincing them the SIM is faulty is nigh impossible. I'm receiving calls and texts on 3G, and get data all the other times, so it can't be... can it?
Argh, as you can see, this is slowly driving me mad..!!!
Yours sound worst than mine. I used to have very reliable 3G data until upto mid October. After that period, there were numerous reports of Orange UK users struggling with data blaming (with high possibility) on merge plan with T-Mobile.
I tried SIM with my Hero and Nokia N82. All 3 phones suffer the same poor 3G connection and in places I spend my time mostly, all struggle to get any form of internet. Few months back on same places, all my mates were impressed by Orange's coverage.
Yesterday, out of nowhere I received a sms from Orange confirming that merged plan went well and customers are to benefit from all cell towers of both network. Couldn't stop smiling then tried to access XDA on N1's browser. Safeguard was ON and access denied. Tried to open few more, all same. Frustrated almost dialed 150 but couple hours later, all started as normal with H signal. No interruptions, no waitings and no error msg. Tested for almost 8 hours. Though still to confirm the reliability.
One more thing I noticed is that before I was using WM's AVS kernel. Almost always once in every 4 attempts, a msg would pop up on error connecting. Changed to SVS kernel and msg still would appear but very very rare. BTW, on latest Nightly.
Coming to end with orange contract and if problem continues, I'm moving to O2.
Try your SIM on other phones to see whether it's the issue with N1.
I might have the same problem. but this just came up 2 nights ago. while connected on data network, all is fine until it drops to 3G, app (opera mini) freezes and you will have to force close. restricted my network to 2G and all was fine. then a while ago i enabled again on 3G and all was fine again.
is this a sign that i may get your same problem soon?

[Q] vodafone uk 3g issues?

Having slight issues with my note on vodafone Uk, whenever I try to browse the internet and the 3g sign in status bar shows weboages don't load at all, when the H is showing bam they load really fast, and even when the E is showing they load but slowly, which is to be expected with edge. So why wouldn't it be loading when on 3g? Have I got some setting wrong on the phone?
HSDPA is faster than 3G.
3G (3rd Generation of Telecommunication Standards) is a standard of cellular connectivity which allows for speeds of up to 384 Kb/s downstream and 64 Kb/s upstream. 3G HSDPA is a 3G enhancement. HSDPA (High-Speed Downlink Packet Access) is a new mobile data protocol and is sometimes referred to as a 3.5G. Theoretically, HSDPA speeds can reach 3.6 Mbps downstream and 348 Kbps upstream. But the purpose of putting both on a smartphones is to make sure that your phone get internet access even when the other one is not available or have no access
possibly an issue with vodafone, have you contacted them to see if there are any issues?
as for the above post, totally irrelevant and hsdpa wil lgo alot faster than 3.6

Yeah they seems to think my sim card needed resetting, but hasn't made a difference, still does it. Hopefully someone has the same issues with a work around searched the net for hours, with not effect. The other weird thing is if its stuck on 3g and not loading I usually disable data on power button menu then er enable and H usually comes back and it works again, even if I turn it to GSM only in network setting, so Edge is only possible it works fine also just takes ages to load any pages which is annoying!
how long you had the sim card? it might be a provisioning issue with it
You think? Well I've had it a few years now like, 3 I think.
Vodafone SIM card works fine in my Note (SIM free from Germany).
I'd suggest try your SIM card with a different phone and try a different SIM card in your Note if possible to see if the fault is with your SIM card or Note.
P.S. Are you using any custom ROM? Could be a problem there.
No I'm on stock rom kka, yeah sure its something today with network or sim card, just rang them to get a new similar. Hopefully that will sort it out.
.
Fixed my issue, turns out it was happening a lot with people who have the galaxy s2, needed to enter code *#301279#, and release 5 hspa only, then disable fast dormancy mode on the phone, now I'm getting fast 3g everywhere :-D
It does say 3g and not just g?
if youre in the uk and only getting edge or gprs it may not be the phones fault.
I had a similar issue, we all assume we can get full 3G everywhere, not necessarily.
To solve this you need to buy the Vodafone sure signal box, it basically plugs into your home broadband router and then transmits full 3g around your house to whatever numbers you register on the box, including dongles.
The whole family can use it as you can register 32 numbers into it.
Cost about £50 new, i have a BNIB never been used or taken out of the box new one here, up for sale as it happens for £25.
Anyone interested should PM me....
Or you could just use wifi as you are at home anyway.
As I said sorted the issue it had something to do with the phone locking into search for hspa, and not reverting back to 3g when there wasn't any hspa signal. Apparently its a problem Samsung are working on. But the little fix of only scanning for 3g works for now, and I did a bandwidth test on hepatitis, and 3g, and 3g was actually faster. So not bothered.
Great find bud u should start another thread explaining the steps in a guide cause this is great info for Vodafone UK users

Is it my phone or the network?

I'm having a hard time figuring out if i'm having a phone issue or is it a network issue that I need to get used to. Simple tasks such as navigation I can rarely get to work if i've already started moving. It will act as if searching for service for 2 or 3 minutes before it gets a lock and will begin navigating. I have had times with AT&T where I had little to 0 service and navigation would pick up fine, but with Sprint I see connection lost a lot more. Is this a Sprint thing or you think I got a bad phone?
I will have 3-4 bars of service on 3G and can stream music but refreshing something like Twitter can take several minutes or timeout completely. I live in Atlanta and have rarely seen 4G/LTE which I believe to be strange because Sprint's coverage map indicates they have strong coverage most of the places i've experienced the hiccups.
What do you guys think?
I think it's a phone issue. I have it as well. ...at least the "GPS lost" issue. Didn't have it with my note 2. I get fast GPS locks though.
No issue with data except for sprints typical slowness

I haven't had that issue but I don't live near anywhere as large a metropolitan area as Atlanta so that could be an issue. My GPS locks are nearly instant but I do have problems streaming music sometimes.

I would call Sprint Customer care and tell them you are having issues with data services and that you have heard of this issue. Have them verify your UUIC ID number under settings/about/Phone identity. This is also the same as the SIM ID. They may say oh thats for international only but what they don't know yet is that number must match on your account for all your data services to behave properly. I figured this out after 6 phone exchanges.....the phone was fine....it was that number that was messed up.
My symptoms where:
- Slow data
- Dropped calls
- Radio was always using EvDo rev. A (check in settings/about/network)
- Never on EHRPD (Required for 4g LTE handoff with the towers)
- 104 data errors (these still happen but much less and is because they are still building out the 4g network here)
I hope this helps and will fix your issues. It did for me.

[Q] Cell reception indicator constantly flips between "no reception" display and bars

[Q] Cell reception indicator constantly flips between "no reception" display and bars
I'm using the Xperia Z3 Compact on TMobile's network in the US.
About 1/4 of the time when I turn on the display the phone indicates that it has no cell reception:
1) The phone shows no bars of reception, and a red X over the bars
2) The lock screen reads "Emergency calls only"
However, within a second or two the phone appears to acquire an excellent signal and I get a full 3-4 bar display. All of the areas in which I use the phone are marked as "Excellent" on TMobile's coverage maps.
This also happens intermittently while I'm using the phone. I'm not sure if it's actually losing the signal or if it's just a software issue. I've never had it drop a call or cut out while I'm talking.
I'm getting only acceptable battery life from the phone (about 25% at the end of the day) despite light usage and conservative app installation, even though this phone has a reputation for excellent battery life. My theory is that this might have to do with the phone constantly disconnecting from the network and then having to re-aquire a signal.
Anyone else had this experience with the Z3C?
Hey mate.. I posted the exact same issue a couple of months back. I was experiencing this exact same issue.
I've had my LTE disabled for about a month now and haven't had a single drop.
Not sure if LTE is a dealbreaker but since my device is a business line, I can "suffer" with better battery life and slower internet if I'm not dropping calls. I've considered trying a ROM with updated radio firmware but figured I'd wait to see what the current Lollipop update does ('ll re-enable LTE once I install it and see if it repeats the same behavior) for my phone before trying a 3rd party system.
Hope this helps

Thanks! Really gratifying to know that it's not just my device. Seems like there's a strong possibility this is the issue since I'm on a MVNO that's only been on this LTE network a few months. I've flipped the device into GSM only mode and we'll see if it helps.
Dumb question how do i flip it into gsm?

Thanks!!!
I'm having the same issue as you have described. For now I've set the phone to 3G prefered. Looks instantly better. Signal strength is also better.
Provider: Simyo (KPN network) - The Netherlands
Edit - Issue solved:
I switched from the Lollipop Baltic ROM to the Lollipop KPN carrier ROM for The Netherlands. The switching is gone for me. Battery life drastically went up.
Any update on this? I just started experiencing this issue out of no where about 2 weeks ago. I'm not rooted or anything, can't afford to due to job security requirements and such.
