Problem with Three 3G network - Xperia SP Q&A, Help & Troubleshooting

Hi guys,
Really hope you can help me out with this one. I have a Xperia SP with the latest firmware .254 and I am having problems connecting the Three's 3G network. The problem is intermittent as sometimes I have 3G HSPA network and then sometimes it flips to 2G which on Three's network there is no data I am happy it is not a signal issues as I have the same phone in the same spot with both 3G and 2G, it just seems to be intermittent whether I can get 3G or 2G. Also, when I try to force 3G only it flips back to 3G prefered when I reboot. Hope you guys can help with this, I will try and provide anything else that you guys think might solve the problem.
Thanks

Cab you look on 3 web site does it gives info on there signal if probs in your area.
Ask for new sim card.
Try diff phone on same network see if there is issues.
I am on 3 in UK northants area,I have full signal but in house there are 2 black spots kitchen and bathroom were I get no signal.

Thanks for that info, turns out that there is a must fault in my area (South Devon), which explains why the problem is intermittent as we have 3 masts that serve our area. Hopefully it will be fixed soon!
Thanks

Calling to UK o2 customers.....

Hi everyone,
I am trying to find out if anyone in the UK on o2 is able to see "3G" on there notifcation bar at the top?
I have been trying to find out for a while and have recently changed my sim card to a 3G as i have had mine for ages and was still an old 2g one!!!!!!
Since swapping I still only see G all the time while downloading data. Does it actually change to 3G when its available?
My current settings are:
o2 mobile Web Post Pay
APN mobile.o2.co.uk
Username: o2web
Password: password (i think!)
APN Type: Internet
Any help would be great
Regards Jim
Well when I'm inside I get HSPDA, I some times see the 3G logo, not often, but HSDPA is better anyway, when I have a decent signal or it drops to edge, but outside I always get it, It could be due to lack of a decent signal?
Make sure in Mobile Network Settings you have Network mode set to GSM/CDMA (Auto Mode)
My Internet settings are the same as yours
So you actually see a 3G logo then.........humm
I checked my network settings and mine are on auto as well.
Im wondering if there something wrong with my phone????
The only reason I say this is because my m8 is on 3 network and when were next to each other he can pick up a 3G signal and I cant. I find it hard to beileve 3 has better network in my area. Specially I always have a 5 bar signal.
Cheers for replying

Have you checked your signal on the o2 post code checker? I wouldnt bash three's signal thinking o2 is better! as 3 network share nearly all 3g sites with tmobile now and have really good coverage so dont use that as a president.
Also best to try your sim in a unlocked/o2 phone in an area that you know gets signal like the o2 shop. Also i didnt think any network needed new sims for 3g apart from orange with the strange usim!
I see both H and 3G.
Yeah i needed a new sim. Got mine about 4 years ago and was told i had an old 2G sim. I didnt know they updated sim cards !!!!!
Ill check the postcode checker on the website and will probably go to the o2 near me. Hopefully Ill pick it near there.
Im not overly bothered about having it where i am, just want to know it works ok.

[Q] S III mini network issue

Hi guys,
I own an i8190, baseband : I8190XXALJL and I encounter frequent network outage.
Although the signal strenght indicator shows 3-4 bars, I cannot be called, cannot call and data is not being fetched.
On battery usage app, the network is most of the time "green".
On any other phone around me (blackberries, iphones, SGS II and III), and on the same network the problem does not reproduce.
If I turn the phone to airplane mode, and then back on, I am able to call, send mails so on and so forth.
Does any of you have the same problem ?
If any of you updated to I8190XXALL2, is this problem still persisting ?
Should I send it to the service ?
I'm currently running the ALL2 baseband, but previously had both the ALJL and the ALK6 ones and didn't encounter any such issue...
Before sending it back you could try with a different SIM card, maybe yours is acting up (it sometimes happens, especially with old SIMs).
Seeing how nobody complained of a similar issue though, I don't think that changing your baseband will have an impact, but if you'd like to give it a try you can download original firmwares (that contain the baseband) from here: http://www.sammobile.com/firmware/. In order to install them, just follow the steps in the root thread.
Will do so. I'm going to pit-stop my SIM card @ Vodafone and let you know about it.
It's strange that this happens only deep inside buildings (eg. offices, malls, etc..).
When this happens, usually the data activity indicator disappears OR the S3 mini is using 3G frequencies (not H, not G, but 3G)
Just changed my sim card and the issue still persists...
It's driving me nuts. My feeling is that the S3 mini doesn't lock on a network cell when 2 are available with similar coverage.
Will upgrade to the latest build and let you know about it :banghead:

And now the handset runs XXALL2 from vodafone uk.
I'm curious if the phone will have that network issue furthermore.
Happy Holidays!!

So far there's no difference. Where I live the network coverage is pretty bad, but it doesn't "disconnect in the background".
Only at the office I can test it out for sure or inside massive buildings.
ci6i, go ahead and update; install kies (for drivers only ), get odin3 1.87 and flash it with XALL2 from samfirmware.
Lately I see there is XALL3 available for some asian countries.
I still think that my BlackBerry 9810 is a tank. unfortunately vodafone romania doesn't sync emails two ways via BIS so... :crying: I had to get back to samsungs...
Well, i understand to lose signal if network coverage is bad, but my phone gets "network stuck" in the middle of town. I noticed this few times: at job, the phone stands on the table near me, and i receive sms about missed calls (i have voice calls diverted to voice mail when unreachable). If i try to call or browse the net at this moment, it's impossible until i set airplane mode on then off. All this time, the phone shows full network signal and HSPA data connection.
I'll try to change the firmware after hollidays.
As mentioned above, try to change firmwares (to XXALL2), I've also noticed some network drops when I'm at home (however this is expected in my case), but when I installed this firmware, I noticed some signal gain (full on 2G and +1-2bars on 3G signal).
Hi again.
The same issue even on xall2
Just happened again today in a crowded place.
It goes to "3G" from "H" and then it's gone off the network.
Will try with XALL3 although there is a small improvement concerning "sticking to the network carrier". It seems it'a hard job to get a call when in coverage area...
If still no success, I'll loose my patience with this Sammy...
See ya!

You get SMS because they use a dedicated network bandwidth for this technology and apparently the S3 mini does not loose connection on this communixation channel.
It appears that S3 mini is dropping voice and data, but not sms and CB (cell broadcast).

LJL version. No drops. Sometimes when i am on edge of 3G coverage area

Hi, i also have the problem with vodafone Romania. I can't place calls or use data connection. After reboot everything is ok. I tried to switch to Airplane mode and back, but no results.
Same problem over here

Hi bogdangr,
I have the same problem with my SIII mini. From time to time, after working normally, it loses the H or 3G symbol and shows about two or three signal bars, but if I try to make a call or receive one the operation fails miserably. The airplane mode trick doesn't work for me, and I have to reboot the phone to get it working again.
I've updated to the latest official firmware, but the problem is still there. Have you found a solution for this or anybody has more ideas of things to try?
Thanks you all,
MFC
I'm on VF RO, too.
Crappy phone, what can I say.
If it can't follow a network where there is sufficient coverage...

Hi Miguel,
The only workaround for this issue (at least for me) is to keep it in GSM mode (no "AUTO mode", no "WCDMA only").
So the crappy phone won't have to switch frequencies and I can get phone calls (I start considering a luck when the phone rings...)
I'm on 4.1.2 now baseband I8190DXALL3 (latest on samfirmware) and still the same.
You just don't want to know how's everything downloading limted to GPRS
BR,
Bogdan
Does anyone know what's that *# code that enables service / engineering mode ?
I want to select on which network frequencies is the phone allowed to work.
I want to disable 3G mode and leave GPRS, EDGE, and HS(D)PA only.
The reason is that when the issue appears, S3 mini switches from "H to 3G" and "G to 3G" and then it's gone;
Although there are moments when it can fetch data with network on 3G coverage without problems...
The code is *#*#info#*#* but it doesn't work .
I don't think it's a good ideea to disable those settings. Maybe it's a temporarily problem and i know Vodafone is testing/launching 4G coverage.
For me, this network issue is happening once in a week. How often do you lose phone signal ?

I found out the service code but the RF setup is not "sufforted".
Vodafone has implemeted already 4G in selected areas but it's not about that. On blackberry, iphone and nokia this is not happening.
As a frequency... 3-5 times a day while I'm at the office.

I'm using it with Orange Spain. I will try using the phone this weekend with another operator to find out if the problem is operator related.

[Q] O4X Weak Cellular Network Reception (Particularly 3G)?

Hi,
I have my O4X since Feb in India. My room is in corner of my house so reception is generally on weaker side. But I have noticed that my O4X has weaker reception as compared to other phones, even cheaper Chinese android phones get better reception than this.
Coming back to problem, using same network sim in both my O4X and my Xolo (cheap android phone), at same place at same time I get 3 out of 4 bar of reception in Xolo, whereas my O4X shows either no bar or just a single bar out of 5 bars. I tried different operators, different sims but this reception scenario remained same, all are 3G network sims. While on 2G network I don't really see any issue with reception. I am getting insane as to what is causing this issue, I have noticed this thing since day one, with ICS, JB, now I am at CM 10.1.
Is this a common issue with this phone? Does it have weaker radio/reception? Or is it with my handset only? Shall I give it in for repairs? What you guys suggest?
Thanks in advance for all the suggestions that will come my way..
I am from India too. I think you are using any phone cover, maybe. It makes problems. For me it happens. I always remove my phone's cover when using net. Also, there are some network frequency that receives low signal. I am using Reliance 3G. I am in west bengal state. In my house west bengal network works well. In my friend's house kolkata specific signal receiveing is well. Also, in his L5 kolkata network's frequency works out well and in my 4X wb is better. When he came to my house he has no signal reception in wb network but I was using it well and I got to his house I had no signal or bad signal reception in Kolkata network.
In short everything is device specific but our device has better network reception. You can try to set network manually.

I do use a mobile cover, will try it without that. I have used Reliance 3G, Airtel 3G and MTNL 3G all in this phone and generally notice a weaker network as compared to other phones at the same place using same network. I have also noticed lately that generally it gets a normal signal when its kept on bed but as soon as I touch my phone signal drops significantly, sometimes from 3-4 bars to 1 bar immediately. And as soon as I take my hand off of it signal improves.
Well, I am not sure what to do now, will try to use without cover and see. Else it will go for repairs. Only reason I havent sent it for repairs yet is because of unlocked bootloader, will have to relock it and flash to stock before I do. Thanks for the suggestion though.

Mobile data issue

Hi, I'm having some problems with my mobile data connection. I live in Brazil, and I'm always traveling between two cities.In one of them I always have the signal of a 3G+ network. everything works normally.
but the city number 2, I only get the signal H / H +, and with this signal I can't get network access.
PS: in the city number 1 I also have the same problem when I receive signals H / H +
This problem persists independently of the flashed ROM.
Sorry for the possible errors in the translation.
ops... I think I created the topic in the wrong area, sorry.
Its because in city 2 the network isn't enough covered.
Are you the only one with this issue?

Im from the UK and got the same problem. Im on h/h+ mostly. I am working in a metal box warehouse that blocks all signal nicely, so if mobile data enabled the data connection drops or changes to hspda or gprs. I know certain points where the signal is fine so theoretically the connection should b restored automatically, but it wont. If I scan for network provider and register on 3g network of giffgaff it working immediately. It seems the phone drops the previous tower and connects to another which has no 3g capable signal, but in network setting the preferred is lte, so I guess the phone should find the best available data network. Sometimes the only way to go online again is restarting phone cuz there is no data connection at all. Weird.

Signal

Does anyone have any suggested paths to get better reception out of this phone? It is so bad and sporadic constantly toggling between 2/3/4g, signal up and down, etc. I've tried multiple different firmwares

No idea. For me it's actually better than the note 3, s3 and s1.

signal works fine for me too.
The signal's same or better than my Nexus 4 on 3G. I usually keep LTE turned off because that signal in my area is pretty weak and I'm usually using WiFi anyway. Plus, a weak LTE signal (or switching back and forth from 3G to 4G) is a battery drainer.
in my case, Z3C has weak signal reception than Z1C on CM11 :/ in my sister house i had weak but i had signal, i loose signal sometimes in pocket, but everywhere else outside of pocket signal was OK on the Z1C CM11 but on stock firmware Z3C there is no signal all the time i had to go outside home and search for network manually... i`m using only 2G mode to save battery
Did anyone notice in the settings (access point names), there is att phone and sony gprs. The sony gprs is selected by default and there is nothing in the settings (only mcc and mnc). When you select att phone, the phone doesn't work. Could this have something to do with it?

i think it's just with your phone since you're using it on ATT. try entering ATT's APN settings. I'm using it on tmobile and signal is fine and it only shows one APN for me. I don't have that sony one you're talking about.
