Since 2 nights ago (and after 3 months of perfectly operating), my 3G network suddenly stopped working, and I haven't been able to reconnect to it. I can only use 2G (GSM) network.
I thought it might be a hardware issue, but when I search for 3G networks, it actually finds my operator's 3G. When I try to connect to it, it says "Registering on DIGITEL" then "your sim card does not allow a connection to this network". I tried with 3 more sim cards and nothing. If I select "WCDMA ONLY", it instantly says in the status bar "Selected Network (DIGITEL) unavailable".
I did a factory data reset (through menu), nothing. Then a Hard Reset through PC Companion, nothing. I tried turning flight mode off and on, and even turned off and on the radio from the "Phone Information" menu and nothing.
I called to my operator but they claim to see no problem (they're always terrible and useless).
I read somewhere about flashing the radio or something like that! Does anybody knows about this? Any help please?
I have a LT15i running 2.3.3 Built 3.0.1.A.0.145
Baseband version: 7X30A-AAABQMAZM-1290_21-22

So I have a really odd problem with my DHD.
Pretty much after doing a factory reset I can't connect to the phone network.
On the lock screen it says "Limited Service" and will only allow emergency calls.
Also, it nags me about selecting a network operator like every 30 seconds.
My operator is listed there but when I select it my phone says "Your SIM card does not allow a connection to this network."
It's also the same with the "select automatically" function.
Some other stuff:
- I've done three more system restores to see if that fixed the problem. (To no avail.)
- Tried with a couple of friends SIM cards, with different operators, same problem.
- The mobile network have seemingly at random started working, so I could browse the web over 3G, but still unable to call or send texts.
- I've also not flashed any rooms onto it, it's the stock Android 2.2 one.
- Also tried turning airplane mode on and off
I've scoured the web for a solution, but I can't find anyone with a similar problem. Really frustrating.
So hope the great masters here at xda can wave their magic wand and give me my baby back. ;/
This morning my phone lost i-net. I'm no longer able to connect to internet using 3G my browser says error on network and android market says "no connection" or something like that
The icon "H" is still displayed in status bar indicating that there is HSPD connection, but there isn't. Under the "H" there are two arrows pointing up and down, wich usualy stayed gray while no data used, and become bright while data is used. Now "down arrow" is bright all the time - something wrong. The problem is that I haven't touch any settings recently it just gone wrong this morning.
I've done hard reset - no luck, same problem.
now even cannot send sms.
What is wrong ? can I tottaly reset the phone somehow?
P.S. SIM card seems to be alright. I've put it in another phone and i-net and messages go allright.
..how do I get rid of this HSDPA ?
I want force it to regular UMTS (3G)
Hi yonef!
Firstly, I think that HSDPA is the only 3G system in this fone.
So, if you really wanna test if everything is working fine, I suggest you try to put it in 2G mode and check stuff.
Go here: Settings > Wireless & network settings > Mobile Networks > Select network
and select 2G only.
Now try to SMS and surf and see if stuff works. If its still a dud, then a call to the customer care is what you really need!
Although am quite new to android, I have been successfull in modding my trusty old Sony Ericsson K550i fone
yeep, I've just found that 2G kind of working, It is receiveing data (slow), but occasionally it says that there is no connection to internet.
It should be something with the phone, because when I put this very SIM in another phone, 3G is working just fine. When I put it back to the motorola, it is connecting ( "H" symbol apears but there is no internet
Hard reset did not fix it
And it happens jut this morning, I havent touch any settings since last week (weird)
I installed room ( {Rom}{ICS} Official Global CM9), after 2 days my phone's network is disconnected. I reinstall the original room 2.3.4 but only use 2G when I used dataroaming; completely unusable 3G & network global mode always (I fullwipe data before reinstalling room 2.3.4 ; radio 1.09.01.0312 & APN properly installed). Please help me how to be able to use 3G
because my phone is example:
Unfortunately, I'm having the same problems with this ROM on HSDPA that I was having on aeroevan's ROM. GSM is found immediately on boot, however, HSDPA is very flakey. It will succeed in connecting every now and again, but then randomly drops the signal and won't reconnect. I thought maybe I just had a weak 3G signal where I was testing, but I have a BB Bold for work as well and that can easily maintain a 3G connection on the same network. I also had no problem way back in the day with CM7.2, but that ship has sailed .
Also, when the phone is in WCDMA preferred mode, after a while the phone will lose all connections (usually after a reboot but not always), including to GSM and when I go to reselect my network operator I get the message "Error while searching for networks". No matter how many times I reboot the phone or switch to "GSM Only" or "GSM/WCDMA auto" it never lets me again select my network provider.
Dude you already posted the same thing in q&a why did you post here

Hi everyone, so few weeks ago I runned last RUU with Radio_47.23g.35.3038H_7.57.39.15M vodafone bloated ROM. It worked like a charm for few weeks, and now I don't have any internet access. Event if in "Wireless & networks" I've got "Mobile network" ON, but in phone "Testing (*#*#4636#*#*)" GPRS service: Disconnected ; Network Type: HSDPA. So it's kinda sees it, but doesn't connects to it.
Restarts doesn't help...
And when I turn on "Mobile network" it doesn't feels like he is "thinking" (before it took about 4-5 sec to turn on Mob.N., now it doesn't)
Any solutions?

from where you are? because when you flashed radio it is necessery that it is matched to your original radio version.
so as you described your situation might this radio isn't compatible with your phone.
try get back to original radio nothing else you can do i guess or you can once try another simcard might it's just network fault or something.
Cannot connect to cellular networks anymore "Error while searching for network"
My phone used to work fine. Then I turned on Hotspot one day, and I don't remember if the phone restarted or not, but soon after turning on the hotspot and connecting to it, it dropped the network connection and it will not connect to cellular networks anymore.
Everything else is working fine, bluetooth, Wi-Fi. I am not getting any restarts (boot loops). Everything else is fine, I just cannot connect to cellular networks. The SIM is fine because I tried it in another phone; it works fine.
I tried everything:
Resetting the phone.
Setting to 2G, 3G, LTE.
*#*#4636#*#* > Set preferred network type, radio bands (Auto, US, Japan).
Wipe cache partition.
Nothing works. It cannot connect. Does not see any networks at all.
Do you guys have any idea? Is this a hardware failure? What else can I try to do?
