Why the 3G signal on the N900 I'm not working?
 

At first right, after I do reflashing, just suddenly lost my signal and my problem appears.yang my 3G signal is not working (missing) now I only use 2.5 G.ada signals that can help restore it?

I had this same issue. Mine ended up being a fault with the phone and was replaced by nokia.

Make sure you have the correct firmware for you location.

There are several vaiants and I'm not 100% sure they work with all the different regions.

Love the title of this thread.

"I'm not working"

Re: Why the 3G signal on the N900 I'm not working?
 

i'm actually not working too :)

Re: Why the 3G signal on the N900 I'm not working?
 

Try the "2G/3G/Dual Mode Selection Applet" . Somebody probably set your phone for 3G operation, and since reflash, it has returned to default dual/2.5 preferred (dunno why, but the phone will never select 3G on this mode; mine won't, at least), but selecting the signal band thru the applet should fix that.

Personally, my phone has never selected a 3G network, but I never tested it, too. I'm currently in a non-3G area, but I'm going to a nearby city right now to buy a new keyboard, so I might as well test it there...

Btw, I'm not working here, too, lol.

Before I do flasing, N900 I'm all right, my home region is very good 3G signal at all, now I'm experiencing this problem after flashing, I can not use the 3G signal.
I chose the firmware 20.2010.36-2 (Global) is still something wrong?
Please explanation from you guys!
thx

I'm currently using that application, but the 3G signal still does not work? if still there is something wrong in this case?

Re: Why the 3G signal on the N900 I'm not working?
 

Did you already had a look in the phone settings? sometimes my N900 does the same but it helps when i go settings -> phone -> select dual or 3G network mode. then it scans for signal.

Re: Why the 3G signal on the N900 I'm not working?
 

I've done it all, but still, the 3G does not work ? So far my N900 still can not use the 3G signal and the signal could only 2.5G ?

Now what else must I do to get a 3G signal in the N900 working again?

Help me :(:(:(:(

maybe it's your operator who is having the issues? u should check their website or call their customer service and ask if the problem is at their end and not in your phone?

Re: Why the 3G signal on the N900 I'm not working?
 

Have you tried reflashing again? It's possible that the image was not written properly.

Re: Why the 3G signal on the N900 I'm not working?
 

MIne is usually on 2g, it switches to 2g when I use net functions

Re: Why the 3G signal on the N900 I'm not working?
 

I've been asked to customer service and I tried using my friend N900 signal 3G simcard and the results I have no problem, but when you move the sim card into my N900, the 3G signal disappears?

I've tried it before and no problems, but last I do reflashing with the same image file, the 3G signal disappeared suddenly, there is only 2.5G signal? Is there any wrong in me to do reflashing??

Hi all
I just wanted to announce that my problems with the signal and has a simcard clasik work.i just use tricks to prop simcard with strips of paper under Battre and the result is quite good.
Now my simcard back to work and my 3G signal again.

Thanks for your help all.of you can give another solution about this, I would greatly appreciate it :)

Re: Why the 3G signal on the N900 I'm not working?
 

I had this same problem - you have not recently removed your casing have you?

I put mine back together and it seemed to come back on - worth a go.

Re: Why the 3G signal on the N900 I'm not working?
 

Yeah and it seems right now I do not have to prop.work well:)

Re: Why the 3G signal on the N900 I'm not working?
 

The global firmware gives unexpected results.
In India global firmware does not even recognize my sim card

Re: Why the 3G signal on the N900 I'm not working?
 

The 3G signal would lose when the sim was not fitting well in the socket? That's very interesting. I'll bookmark it and refer that to similar case in the future. ^^

Re: Why the 3G signal on the N900 I'm not working?
 

Indeed there must be a proper solution to this problem and later :)
