lousy 3g and the o2 exec

Have just upgraded to an o2 exec and want to experiment with video calling .
there is no 3g signal, it always comes up 'no signal at present' even though the signal has 3 - 4 bars on it. I'm with o2 and unhappy with the service I phone tech support and they tried to tell me to move to another part of the house ....this may have been helpful if I lived in the eiffel tower but i LIVE IN THE uk.
Im beginning to think that the whole o2 3g network is substandard
Any ideas?

Look at the little square icon next to the signal strength indicator - is it a 'G' or 'U'?
A 'G' indicates normal GPRS signal while a 'U' indicates UMTS (3g) service is available.

It's normally G and very very occassionaly turns to a u?

OK, when it shows a 'U' you can make video calls. When it's a 'G' only normal calls can be made.

G being GPRS and U being UTMS which is 3G. I think you can video call via wifi but I've not tested this yet.

I doubt whether the o2 coverage is bad, otherwise why would hutchinson three use them as a carrier for their network, seeing as they are a 3G company? The signal strength bars IIRC dont bear any relation to the 3G strength.

LOL you have the wrong end of the stick m8, Hutch "3" 3G is a pure 3G network (the biggest in the UK) with around 80% coverage. The network is wholey owned by hutch, however if your unlucky to wander out of coverage (into that last 20 %) then it will switch to O2 2G Gprs (no video calls) just so you can at least make voice calls / emergency calls. O2's 3G network has much less coverage than "3"'s but it's ok because it can seamlessly transfer to it's own 2G network if necessary

I am of the understanding that O2's 3g network is not the best in terms of coverage (voda and 3 are afaik). Interesting what is said above about 3 and O2 both being hutchingson compaines and sharing infrasturecture - can anyone verfiy?

they are 2 very diffrent companies, 3 just have a deal with O2, they pay O2 to allow "3" customers to use O2's network when "3"s is unavailable

That would be funky, but don't see how it ould be possible.
I too only get a UMTS signal in Belfast (which is supposed to be a strong 3G area) when I'm upstairs...
They need to pull the finger out if they want video calling to be the norm.

O2 3G around London is okay, not as good as T-mobile of Vodafone from my experience. Using a O2 data card I can get the higher 384kbps download speed, and it really is quick.
Video calls on O2 are part of the normal call allowance, so if can get it to work it wont be as expensive as on "3".

No i thought 3 used the O2 masts and technology, i cant remember where i heard it though.. Of course i could be very much mistaken

11 seconds with 3G

Hello,
I have a DOPOD D810 and using with Vodafone-SP. When I have the 3G on the calls least about 11 seconds (sometimes 9 seconds) and without 3G (the old GPRS) the phone calls work perfectly.
Anyone had the same problem or know why it's happening?

sometimes, when iam connected with pc (usb) and share internet connection to it. i dont try it with gprs.
but when i have 3g connection without pc, works perfect

Is HSDPA in your region? Because i think i have read some posts where the HSDPA implementation makes that problem. Just turn off HSDPA support and see if its ok.

i dont know, but icons switching between 3g and H

i'm having the same problem too. The calls will drop in less than 10secs in 3G mode but with normal calls. Checked with the network provider and the Dopod HQ. Network provide says it could be the hardware problem and the Dopod HQ says it could be the network problem.... this is making me sick. And some Expert says this is normal to PDA's 3.5G phone.

Basically I can say that depends of the cell, I mean, sometimes 3G calls works fine and sometimes not, usually the ones who doesn't work fine are in different 3G cell (becasue I'm in different location).
So, can be both, a network problem (some software or hardware in the cell antena) and the phone (who don't 'talk' with the cell properly).
I search and a lot of spanish Vodafone users (Trinity) have the same problem.

just noticed that after softreset the 3G signal becomes perfect and calls signal will stay strong. But after i awhile without making calls out or incoming calls. Then the nightmare happens again. Checked with the Dopod hardware HQ, they says if the 3G signals drops then the GSM will drops too. So, it couldn't be the hardware unit problem.

Using the HD2 in Vietnam

hey guys.. i took my HD2 to vietnam a couple of weeks ago and I used a local sim card.
I noticed that the signal over there (on Viettel) was a constant "H" as a default. I couldnt get the actual data connection to work (probably because I didnt have the correct internet settings).
Over here in Australia, the signal is always 3G (even though I know I'm in a HSDPA area). When I have an active data connection it changes to "H" temporarily until there is no data flowing through, then it changes back to "3G".
Can anyone shed any light on why this might be? Could it be something to do with the sim card itself? Back here in Australia, I've played with every setting I can find in the phone to try have the constant "H" and have not had any luck.

I get the same thing....an H....in Hong Kong, Manila, and other places. It seems that you are operating off of an HSDPA network, which is good!

Btw, Elly Tran Ha in vietnam really beautiful ^_^

HD2 using in Viet Nam ok, included VietTel, VinaFone, MobileFone and VietNamMobile networks on band 2G, 3G, 3G+, H
Elly Tran Ha is Hot Girl in VietNam, very...very XXX

But in Australia, we're operating off a HSDPA network too but the signal always stays on "3G". The phone only seems to connect to "H" when there is data flowing through.
The H in Vietnam (also HK, i might add) didnt drain any additional battery either....

3g Signal problem

Hello all,
I just got my N4 couple of days back. I have this problem where when i connect to a 3g network the signal keeps fluctuating. As in it connects to the network for some 5 seconds i ll have full signal and after a couple of seconds there is no signal it shows emergency calls only. This keeps happening repeatedly. But in the 2g network everything is fine. I figured this is a radio ( i had .48 ) problem and flashed an older radio ( .33 ) still the same. i m looking for a solution 2g network is way too slow. This never happened in my nexus s :/
P.S : i dint have a micro sim, so i got the sim cut into a micro sim, is this the problem do i have to buy a micro sim itself ?

It's goes according to your carrier's cell coverage. If you're in area with low HSPA+ coverage then you will lose it and it will automatically switch to another frequency band. Big building can block cell coverage. Going underground or being in the basement will lower your data coverage. It has nothing to do with your sim card or your baseband.

I never had this problem with my nexus s, is it because nexus s doesnt have HSPA+ ?

Signal problem theory/research

Hello, i live in a relatively small town where my service provider has very poor 4G signal. but pretty good 3G signal. With the Axon 7 i have a lot of signal problems that i didnt have with any of my previous phones, where outdoor signal is pretty bad and indoor signal is almost unusable. It also connects almost exclusively to 4G, and in contrast all of my previous phones connected almost exclusively to 3G. Over the last weekend i traveled to a major city where my service provider has very strong 4G signal, and the signal problem was almost non existant. I even had signal in places where other people with the same service provider did not. So my theory is the following, assuming that the hardware (antenna) used for 4G and 3G is the same, it may not be a hardware problem, but a problem with the software having a hard time knowing which band/signal it should connect to. It seems that in my case it prioritizes 4G signal and the cost of a VERY unstable cellphone service. This is also assosiated with the fact that when it connects to 3G (incredibly rare), the phone goes inmediately from 1/2 bars to 4/5 bars. I also changed the SIM configuration to leave LTE out, but either for a visual bug or a software bug, it keeps connecting only to 4G. So could this be the problem that me and a lot of people in low 4G signal zones are having? Is there anyway i can force the phone to connect exclusivly to the 3G signal to test if that is indeed the problem?
Regards!

Without knowing which model Axon 7 you are using, where you are using it, and who your provider is, there is little anyone can do to help you. All I can say is that it helped me A LOT to go into settings and turn off
VoLTE.

U model last update, using it from Argentina, and the provider is Claro. I have LTE disabled in SIM confg as i already said and VoLTE turn of as well but the phone keeps connecting to 4G no matter what i do, even if i configure it to only GSM
I don't think its a matter of position or provider (version could be if different software is provided), but a general issue with the phone and band/signal interpretation coupled with the apparent innability to go off 4G
Refards!

ok when it connects to LTE it says "4G LTE". The 4G that you are getting is probably HSPA or something. And we had someone on here a few months back using Claro in Argentina and they had to seek answers from their Claro

If "4G LTE" is 4G and "4G" is HSPA, when only a "G" appears, what band am i connecting too? Its still pretty weird that im having major signal issues in my town, but when i go to a big city my signal is even better than other phones, it seems inconsistent with the whole "bad hardware" theory. I talked to Claro and it seemed like from their end it was a non issue, can you point me to the thread to see if he got it fixed somehow?
Regards!

/Trolling a bit/
I'm always LMAO when I hear US people talking about that 4G scam (which is H+ for real btw)
G is for 2G
E is for 2G+
3G is 3G
H is 3G+
H+ is 3G++ (an intermediary protocol up to 42MBps)
4G is LTE (up to 150Mbps in the EU most of the time)
4G+ is LTE-A (which is available in most of the EU, SK & JP) - up to 600Mbps, 200MBps in most tests
I've not heard of an app that could modify the way the phone "clings" to 4G LTE, since that might likely be the modem firmware doing it on its own.

Then this is even weirder, because is G is not 3G, but 2G it means that the phone NEVER connects to the major band that all of my previous phones and Claro users connect to. Is there anyway to force to only connect to 3G?
Regards!

i have the G european model, in my town i have bad lte signal 1/2bar, when with my previously xiaomi mi4c was got 4/5 bars (maximum). In the big town i have got in the most of cases 4/5 bars. I think the "signal problems" are relatives of a lack of somehow software. i told this because i've read with the china model with the last updates an improvement of the signal reception of the phone.

You can however force a specific protocol indeed, but you will lack the ability to autoswitch networks. Just download 4G LTE Switch (here) which is a glorified secret code dialer. Just click on prefered network and change at your convenience (4G LTE only, WCDMA only - H+ - and so on). Remember that if you force 4G LTE in an area in which you have no coverage, you won't have internet, and no 2G/3G fallback (so no texts, no calls)

I don't know if this is the same problem, but my wife has an iPhone 6+ and I have an A2017U on B29 stock root. We both use the same network (Movistar Mexico) and while her iPhone often registers LTE, my A7 often registers 4G or even E in the same place. The A7 is receiving the same bands but appears to be "choosing" or locking into the slower protocols more often.
EDIT: NEVER MIND… an xposed module was messing with my network settings. Fixed it. Now I get LTE right away.

Which module?

What if flash any Custom OS?Would it give better signal ?
