No 3G and no internet connection on My G1

Hello everyone
I got an HTC G1 which was a UK T-mobile one and that is now on a French network called virgin mobile.
I got all the correct APN entered
But I have no icon of a 3G network and trying to use web give me such messages as « a network error has occured » or « data connectivity problem ».
Use only 2G network is unchecked
In status I have:
Network: Orange F
Signal 63db
Mobile network type : UMTS
Service state: In service
Roaming: not roaming
Mobile network state: Disconnected
I think the problem comes from here I got the 1.6 firmware shall I put a French firmware?
It seems that some other people has such problems but I found no answers….
Any ideas?

[Q] unlocked sgs but now shows no signal?

hi had a search around but unable to find anyone who has had the same issue
unlocked sgs from UK t mobile to use vodafone sim.
all was ok till i changed the setting to stop 3g to improve battery life, sgs went to no phone signal (blue circle with line through it on top bar). put 3g useage back on but still no signal
had a look at my phone/status:
network = vodafone uk
service state = out of service
mobile network state = disconnected
if i set network automatically it says 'registered on network'
if i select vodafone from list i get 'your sim card does not allow connection to this network'
i have hard reset the phone, locked it and unlocked again, but still the same
also tried with o2 sim and get the same problem
== t-mobile sim still works==
is there a solution out there?

Try to manually create another APN
EDIT: my bad...you meant no phone signal. I have no clue but hope that you'll get the help that you need.

what needs to be entered in the fields?

i've had this happen on two phones..........one was due to me messing up the nv_data files. the other was fixed by reflashing.
take your pick

i haven't had the phone flashed
i only used ADB to get the Network Control Key which i then use to unlock the phone
can you suggest the next step for me
i assume the professional unlockers use a flashing method, should i get it unlocked by one of them?

its possible the imei has been blocked

if blocked tmobile customer service said that i should hear 3 beeps when i try to make a call, but i get a message that 'not registered on the network'

could it still be blocked even though i do not get the 3 beeps?
if it is not blocked is there anyway i can get this working on a vodafone sim?

[Q] What network am I on????

Hi. I've just received a Samsung Galaxy S GT-I9000. When I tried my O2 sim card in it it didn't work. How can I find out if my phone is locked to a particular network?

*#7465625# that will tell you if there is a network lock. if there is try this

Who did you buy the phone from and is it network branded is another clue .

Tried that azzledazzle. It says
Network Lock - ON
Network Subset Lock - OFF
SP Lock - OFF
CP Lock - OFF
I've had a look through the settings etc and can't see any mention of a UK network.
JJegan - Got the phone from a (not very bright) workmate but he didn't know what network it was on as he said he never used it. No branding on phone that I can see.

Go to menu, settings, scroll down to about phone, scroll to bottom an give us the basenband version and build number. Then scroll to top and click status. See if it says in there the network name. (it may say no network if you have no sim installed)

Hi Tehpriest. I don't have a sim in the phone as I don't know which network it should be on.
firmware version 2.1-update1
Baseband version is - I9000ADJM1
Kernel Version - 2.6.29
Build number - eclair.adjm1
Just searched for I9000ADJM1 and am I right in saying it is locked to O2.
The O2 simcard I have already tried was an old one (possibly not even 3G)
If I send for a new O2 simcard, is it just a case of fitting it and phone will work?

I9000ADJM1 = O2 network.
What happened when you put your O2 sim in?

[Q] Mobile Network Not Avaliable

Hi, Ive bought a galaxy S, unlocked with no sim. I placed my P.A.Y.G sim into the device and it says when trying to make a call ''mobile network not available'' Ive checked the IMEI number and its the same as the code inside the phone. And ive tried 4 different sims that all work on different phones and no luck?
mobile network type - UMTS
service state - out of service
mobile network state - disconnected
model number GT-I9000
firmware version - 2.3.5
baseband version - I9000XXJVT
kernal version - [email protected]#2
build number - GINGERBREAD.XXJVT
Whats the problem? Can anyone help me please?
Thanks,
John.

This is a long shot, because you may have a hardware problem with the phone - given that it has never worked (to your knowledge).
First of all, you should always power the phone on and off between changing the sim (not sure if you have to remove the battery to get the sim out).
What happens if you pull the sim out and boot the phone up, does it complain about there being no sim? In other words is it behaving differently when there is a sim card in there versu without. If it is, then at least it knows there is a sim in there. If it doesn't then you probably do have a hardware issue.
Have you gone into the mobile network settings and done a scan for carrier networks, does it find any? Select the right one that matches your SIM. See if you are now getting a signal.
Then have a look in access point names (also in mobile settings), press menu and select "reset to default". If it downloads a new list, then that is a good sign. You might have to experiment to get one that gives you data access.
Hopefully that should give you some pointers.
