[Q] Help, SGS has no signal sometimes

My phone is from UK orange. my phone has great signal at home and office.
However, after I upgraded to Froyo JPO version firmware, my phone has signal in my office with 3G but has no signal at home and some other places where the 3g signal is weak or not working. This is very annoying. Please anyone can help me?
My original firmware: JP5/JP3/JP1
My current firmware: XXJPO/XXJPP/XAJPO
MY Production code: I9000HKDORA
Tonight I try to flash lots of versions from samfirmware.com but there is no signal for all firmwares.
Please can anyone help me? It seems that my current wersion does not support 2G signal???
Thanks in advance

can you check your IMEI in the phone (settings>about phone>status) and compare it with the IMEI indicated in the box (or remove teh battery and there should be a sticker at the back of teh phone with your IMEI).
Note: Also check if your APN settings are correct and complete. It might have been deleted or changed after the flash.

I have checked the imei, it is the same. The apn is orangeinternet, I think it is correct.
When I go to somewhere, the phone can be used with symbol of 3g or E or H, but at home only signal bar shown and emergency call only.

It is GSM/WCDMA (auto mode) selected.
I remember I can only choose 3G and wireless network when I just flash the FROYO JPO firmware...

It is possible that orange are working on the network. I had similar issues a few weeks ago (I'm in the southeast) bit is now fine. You could go see your local orange guys and ask.

But I can use this sim card on the other phone, like HTC HD2, perfectly at home. Does the SGS have such bug? I am in the southwest.

try see if you have the missing 850 band bug?

it's normal icon for 3g hspa mode, don't worry, hspa = 3g

It means you've got a HSDPA connection. HSDPA is much faster than 3G. See this link for info on the different terminology

[Q] TeamHacksung ICS Build 3 MVNO

This is a small issue but is anyone using ICS with a MVNO? I have a Virgin mobile SIM which uses the Everything Everywhere network in the UK (Orange/T-Mobile).
When the phone is using the orange network the notification drawer correctly displays this, but when on the T-Mobile network 'No service' is displayed.

Since you managed to flash ICS on your device I suppose you're comfortable doing some more hacking
Try this: http://forum.xda-developers.com/showpost.php?p=12693880&postcount=5
Maybe look at the file first and check if your provider is the one mentioned in the Finland section.

We are now in build 13 and we still get that roaming icon if we are using a MVNO
this method didn't work for me

I have the same problem with spanish Yoigo

Teamhacksung ICS MVNO roaming problem
same problem on build 16
HELP please !!

anything new about MVNO support? on my galaxy nexus in ics MVNO works without a hack, it`s not treated like a roaming network. somewhere in the process of porting to I9000 this stock ics behavior got lost. would be nice to have a better solution then switching data off in frontier areas.

[Q] No 3g network (MTNL sim)

I just got a Note for my Dad and noticed that it does not get 3g network while in roaming. Even if I manually set network to WCDMA it shows only emergency calls.
The same card if I put in my Nokia X6 it shows 3.5g with full network and the internet speed also is blazing fast.
PS: When I search for network with WCDMA selected it doesn't show my provider. Also I inserted the same sim on my Galaxy S2 and have the same issue no 3g network. My dad is so disappointed with the Note and said Nokia is the best
Any help would be appreciated.
Thanks!!

Replace SIM, I can't explain you logic, it just based on someone's expirence i have read smwhr.

It is already checked.

Well I have figured out what the problem is. NO matter what sim I use when i set the phone to WCDMA and search for network it does not show bsnl network buts shows all network(Vodafone, IDEA etc). There is strong 3g bsnl network in my area and it shows on other phone. IS samsung unable to catch bsnl 3g network? THe saem problem is with my S2.
Thanks!!

I tried different sims but it still do not recognize Even the phone do not ask PIN CODE
I check the network settings...
I know that the crossed circle means some problem about the modem... But there is no crossed circle... There is normal signal symbol. My imei also OK. I dont know what the problem is...
