Phone Reception and a Question

Why does the IIi suck so much in cellular reception? Half the time it's 'seeking a signal' and the other half it's at 1 to 2 bars. The moment I enter a building, it drops getting a signal...
On my Razr V3i that came with my provider (Rogers Canada), I get four bars in the exact same spot that I had 1 bar or nothing on my IIi.
Is there any way to improve reception, because I'm really tired of carrying my PPC phone and razr around.
Also, say if there is no sim card inserted, does that mean it turns off the phone component and saves me battery, or do I have to turn on flight mode (which means I don't get wireless either) for that?

could give another radio stack a try

help with signal

i love my diamond and most places the signal is good, but in my house my signal is crap, if i get a call i have to go outside, i have tried a few differant radios but not much change, ive also brought one of those signal booster stickers of ebay but not sure where antenna is on diamond, my wife is on orange and her samsung gives good reception in our house. just wondering if anybody can help

well in the states verizon wireless has released network extendors that can connect to your broadband internet connection and broadcast cell signal, thou looks like your overseas so i'm not sure if any the gsm carriers have anythign like that, thou they do make cell phone boosters or amplifiers that would increase your signal
you said the other phone has good signal in same location, here you could grab that tower id and edit the prl with it or change home sid so that phone talks to it but at the risk of possible roaming charges depending on your carrier,
i'm guessing you have a gsm diamond? if so i think your version of PRL is called internernational roaming database or IRDB, not sure if it can be modified on the gsm side but might be worth looking in to unless you want buy cell booster ( good ones are usually $200us or more i've seen some over 1k but should get decent one for 200
you mentioned sticker antenna most the cheap ones i've seen are groundplanes that hide between the batter and phone, thou not sure that would be good spot, thou if your refuring to an actual antenna that use proimty to transfer signal instead of connection, the internal antenna on most phones is on the back at the top

thanks for your reply runkittyrun, ill look into your thoughts

SGS Captivate Got Signal. Can't Use Network

So almost two months of owning my Captivate that I got from Rogers (BNIB from Kijiji) and I noticed that at a certain area in my school, I have 3/5 bars of signal yet I can't seem to text/call and use the network. Is this a network problem or phone problem? Or can it also be my SIM? My SIM card is pretty old. However everything was fine when I use my Sony Ericsson W715 in the same area.
I should add that my friends on the same network beside me, they can text/call fine, which leads me to believe that this is a phone problem. A poster over at Howard Forums suggested network congestion, but it seems impossible because everyone else can use their phone fine.
I've tried different modems too, but it doesn't help. It's like my Captivate doesn't want to work at certain areas of my school.

A couple of people are getting the same problem as well where the phone reports good signal, but they can't use the network at certain locations. We're starting to think that this is a phone problem...

I noticed this same issue in fringe areas. I have ATT and in southern Utah they are quite weak. I wonder if the bars/signal are actually from another provider like T-Mobile or some off brand like alltel or something. Utah has a bunch of small providers in rural areas.
Specifically in my case I go up in the mountains at Brianhead Ski resort and i get 2 or 3 bars yet I cannot send texts or call. Verizon has coverage there and I heard rumor T-mobile had a microcell or something on one of the lodges.
Could the signal be from another provider that ATT doesnt have an agreement with? Or in the OP's case some provider besides his own?

That's highly unlikely though, the idea of my phone roaming onto another network. It'd show if I'm not on the Rogers network.
Plus, a lot of people use Rogers, such as my friends who are able to make calls and send texts when they are next to me while I can't at school.

Just an update. Switched to a new SIM card, no go. Got a reconditioned Captivate, still got the same problem. As always, everyone else around me could send and receive text messages fine.
Same thing happened to me twice today with the reconditioned Captivate, at two different locations. As usual, it happened to me at Ted Rogers School of Management on the 8th floor where it showed I had 3 bars and a 3G connection. However when I tried to send a SMS, make a call, or browse the web, nothing worked. Everyone else around me was fine though, so I still can't determine whether it is a network or phone problem. I already switched the SIM out for a new one too.
The 2nd time it happened to me today was just outside of the subway station. Keyword is outside. I wasn't underground. I had full bars, but again I couldn't use the network.

I still think it that in some cases our phones pick up out of network signals and show great signal strenght.
Maybe not in your case since others are working fine around you, unless they are bone stock maybe, and you have obviously improved your phone.
I did a bunch of expeirmentation with my phone, flashing different modems and such, trying to get an ATT signal at Brianhead Ski resort in Utah.
I could get the phone to show great signal on the bars and in settings/about phone/status but the service state and network would say unknown or unavailable, somthing like that. (maybe check those when you cant get out?)
I have since given up and reflashed so many times I dont remember which modem worked to give me good signal of networks I couldnt use.
I do know it was frustating as hell to have full bars and be unable to call or send texts.

Thanks for your insight. The other people around me have other phones, such as Blackberry, Samsung Wave, etc. I even tested it with my old Sony Ericsson W715 and my friend's Samsung Wave at pretty much the same location (a feet or two away from me) when I can't use the network, and everything is fine so it most likely is a phone problem.
When it shows I have signal, it also shows the service state, like I'm on the Fido network and such.

Weak Signal area Radio Power Meter Questions

I live in a weak signal area, my power meter (found at: setting,wireless, mobile network settings, networks type and strength) rarely if ever goes below -90 dbm. I often monitor the VZ network by using it. I use my phone for Internet (even with a weak signal my phone has provided me better service than my other options).
I have often observed an odd behavior reported by the power meter, the meter will jump from its current reading to -1 dbm. This occurs only on the 3G network tower. There is also a 1X tower at 4 miles away that I have not observed this very unlikely power reading.
Anybody else have this experience?
Could there be a front end amplifier/attenuator on the radio? If so I would think my phone has a defect.
Thanks
Steve

Update: I took the lack of folks having the same problem and another issue this phone's hotspot/tether process to mean this phone had a defect. I was able to replaced it today with a new phone.
I observed that the new phone has the same issue.
Does anyone have schematic for the front end of these radios?
(I wouldn't think this to be possible that LG would give out this information, but I thought I would as)

My understanding is that the radios have not been released, giving us so much trouble getting ICS and other things to work. as far as signal issues... i think it's the phone it self. not yours, but all of ours. I know in a small town out where i live, i have to use a different carriers tower, Verizon doesn't reach well... and my friend still has 4G. he's using thunderbolt, other friend has 3g through at&t... so i think our radios may be underpowered.

Z3+ Signals, No GSM, jumping 3g.

Hello.
I bought my phone just 3 days ago together with my gf.
She bought the exact same phone and same carrier as me on the same shop..
Around here we are supposed to have good 3g signals all over, but not inside our house, there we can only use GSM.
Her phone works perfectly, with 3-4 bars gsm signals inside house.
But i get nothing when entering house. NO bars what so ever, (even if i pick GSM ONLY from settings).
I got to service menu and read "0 db" on signal.
I tried everything, Clean sim, restart phone, factory settings, changing GSM/3g/4g priority etc, and even tried MY sim in HER phone.
Its defo a hardware/software issue on my phone.
My experiences from 3g and 4g with this phone is that 4g seem stable and good, while 3g (outside my house) seem to often go from max to none all the time. jumps up and down
and sometimes leave me with no signal for 5 minutes until they are back.
I contacted the carrier to check and everything seems fine over there.
Any suggestion? Could it be really possible that i got a faulty antenna? if im going with my phone to the store for a replace they would probably not belive me or take my reason for real
EDIT: Have to add that the past 12 hours of constant trying to figure out the problem i had a few cases with signals while i was trying to switch to "gsm only" but they lasted for 5 seconds and were gone again.

Had the same, send mine back, saw in the log of the repair department that you refreshed the software. But will check
if they have changed something. Comes back in a few days from now.
