Hi
My I9000 sgs is currently showing full signal but whenever I make a call it just comes up with the message "Mobile network not available". Texts will not send either.
However I can still browse the internet (not connected to wifi) even though it says there is no internet connection, I just press ok and it continues to load up the page.
I have tried flashing various stock and custom firmwares, as well as trying various different modems.
I have unlocked the phone to see if it was just my orange sim but my o2 doesnt work either both have the same issue, both my sim cards are working in my friends sgs2.
I have also checked my imei number to ensure it wasnt blocked, its not.
I have now exhausted my knowledge and cannot find any solution after 2 days of googling.
I would be really grateful if anyone had any ideas on what else I could try.
Thanks in advance.

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.

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??

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.

Hello.
Having problems with my I8190N. About 2-3 days a go it suddenly lost ability to connect into internet. I can switch data connection on or off, it doesnt make any difference. I have tried to reflash various ROMs and it's all the same, no internet. I get the usual signal bars but no H/G/E marks.
It did not happen after flashing, had CM11 on it for days and I could connect Internet just fine. No carrier limitations either, I can make calls out and same SIM in my old phone can go to internet.
Should I flash the stock ROM/bootloader back and RMA it? Or is there something else I can do? (perhaps known issue and solvable on my own)
Phone is fairly new, bought it in August as brand new.
i suppose APN settings are correct?
you can try to flash another baseband to try with it, what is yours current baseband?
basebands you can find here for N version, XXAMJ ist newest and working for me...
I had the same problem a couple of days ago. It turns out that my problem was the simcard, have you tried to put another simcard in your phone and see if it works?
I have this problem, same with two phones and two SIM cards, both phones are ZTE, both problem SIM cards are on Vodafone, both phones have no problem connecting to data via t mobile sim? This leads me to believe that voda data does not work on zte phones, apn details are correct. Does anyone knowa fix?
finally sorted it........... f'd around with a few different apn's and even phoned up talktalk(same as vodafone network) who confirmed I had the right settings which I hadnt!
Found the correct settings on the geeksquad website. seems i didnt need to bother filling out some of the fields and then wham internet connection straight away!
Sent from my ZTE V967S using xda app-developers app
Two days ago, out of a sudden my phone stopped connecting to the carrier (Rogers, Canada). I can't call, send text, or use data at all. When I go into Access Point Names, my Xperia Z shows the lterogers.apn installed. If I go into Service Providers I can see a list of Canadian networks, I've tried connecting to the LTE, 3G, and 2G networks of Rogers to no avail. Also, I tried my SIM in a Nexus 5 and it works, I also went to the company and there are no issues with my account at all. Any advice on how to solve this?
same problem

Hey guys
I'm having the exact same problem! Haver only had the phone a month - previous xperia z replaced due to sudden death - and then this morning I lost my mobile data connection, closely followed by my entire reception. I've repaired/reset the phone multiple times, all per Sony's instructions without any luck. Hoping someone around here has a fix for me!!! At the moment just bashing my head against the wall with this phone and its issues!

Have you solved the problem ? I have same issue , after many others...pls help
Hello guys!
I'm asking on behalf of my friend regarding his HTC ONE M7.
The phone is running fine on WIFI but, there's an issue with the network service. It takes a while for the phone to pick up the network operator and when it is connected to the network, it shows full bar with 3g signal. The issue is that, my friend cannot make a call or browse the internet using data network. Even when he tried to check his credit balance, it would sometimes show the balance and sometimes it will display and error with "Invalid MMI code" or something. Same thing goes to making a call, sometimes he can call, sometimes he can't.
I tried to make a call from my phone to his phone and sometimes it's ringing and again, sometimes his phone can't be connected.
He flashed new ROM but the issue is still there.
Any of you guys have any idea on how to fix it?
Thanks!
change SIM
Hi, so my problem is that i keep losing mobile signal (3g and LTE). I put the SIMcard to another phone and everything works fine.
Did a factory reset and still nothing, i even installed Sony Stock Jelly Bean ROM and again nothing. When it's set in 2G it works ok.
The other thing is that i can't tell when the signal is lost because it actually shows that there is signal but when i want to call someone or use internet i can't. Could someone help please

You might have an issue that is similar to mine. My XSP also shows signal, however, the difference of your issue with mine is that, I cannot receive any SMS, or calls. If I attempt to call someone, it somehow "triggers" network polling and then the signal resets to a correct one. After then I am able to receive calls.
However it is persistent, later in time it will "freeze" again.
I highly suspected that it was my XSP. Fortunately upon some closer look, the true culprit would be the radio tower (reception) at my home. At my university, the network works extremely fine. And if i return to my home, the same issue reappears.
I guess you should try going to somewhere else that is quite far from your home, and check if the issue persists.
If you are however having such issue constantly everywhere, it might also be plausible that a certain bands are out of service at your area
Well about the area service, my friends SG S4 is with the same mobile operator as i am and has no problems with the signal or mobile data. Any help on what to do ?
