I lost most of the signs of my phone so much like the wireless range as mobile networks in general is no problem with roms because I 've tried about 10 roms and is the same in hardware change the slot of the sim but still I have coverage that I can do?
first of all, Thanks

Am facing a weird problem on my Galaxy S I9000. Some days before, I went out of my Carrier Hot Zone, i.e. on Roaming and lost network signals for the entire stay of my roaming period.
I have inserted the sim card in another phone and it worked fine. But on my Galaxy S, now, even in the hot zone, i.e. my local network does not show me any signal strength except emergency calls. Again, sim card works fine in another phone.
Now my Galaxy S won't accept any sim card and shows no network signal. I have tried flashing different ROM's and Modems with no luck.
Any solution to this? Thanks in advance.
Hmm,
Are you sure that Airplane Mode is not active ?
I have the same problem, after a root my i 9000 y lost signal from my carrier. i have tried dierents roms and modem with no good results. any help? i appreciate... thanks
Try flashing another modem

I purchased an unlocked I9305T a few days ago to use on Telstra and am having all sorts of reception problems even though we're fairly close to a tower. My S2 will usually get -80 dbm and above whereas the S3 was often sitting at -100 or less. Sometimes mobile data works and other times it drops out constantly or won't connect at all.
Anyway I was ready to return the phone today when I noticed that without a sim inserted, it's getting better 3G reception than the S2. That would rule out any antenna or modem problems wouldn't it? Does this mean the sim card slot might be faulty? I doubt it's the sim card itself as I've got it in the S2 currently and it's working fine.
EDIT: Please excuse the dumb stuff above. Don't know why I thought signal strength meant anything without a sim. I went and got a brand new sim and it's now working perfectly.
Hi everyone,
I bought myself a nexus 4 and I gave the P990 to my girlfriend.
I did a factory reset and inserted her SIM card (the mobile operator is called Free, a french operator), and I got a "roaming" symbol in the network. This was with the combination I have in my signature.
I've been trying different basebands today, and now I can't get any reception at all, it just says "No network".
Now I'm with DjangoManouch stock rom, 218 baseband, still no network with Free's sim card, but I tried with my sim card and it's working perfectly... I tried Free's sim card in my nexus 4 and it is also working perfectly...
I did get "normal" reception using the combination in my sig with free's sim card at a specific location... my best guess is that free's cell towers need a very specific baseband for it to work correctly? Do you have any ideas?
Thanks a lot in advance.
Cheers!
Slight update, the total network loss was solved by changing to the correct IMEI (it must have been reset by one of the flashes I did).
But the "roaming" problem is still there Manually selecting the network solves it temporarily. Has anyone ever had a similar situation?
Thanks!!
Did some more research... apparently her network has very limited coverage, and for the areas where it is not covered it has a deal with another operator, Orange.
So, whenever she doesn't have "official" coverage, she'll get the roaming symbol. And apparently they have an app to avoid people in the border to get reception from foreigner operators, which would mean "real" roaming, which is odd and interesting.
Anyways, hope it will help someone...
Hii guys i'm new to xda...
Sorry if i'm posting this in the wrong section.
I bought a xperia SP recently and i'm facing battery issues in it, i tried different softwares and everything nothing worked, finally i changed from WCDMA to 2G only now the battery is perfect, its draining my battery alot in WCDMA mode. I tried changing my sim with a different operator and now its working perfectly but i want to go back to my earlier operator where when i use that operator the battery sucks. Could anyone suggest me an solution. I'm from Sri Lanka

Hi mate, I think the solution for the problem is very easy - take the second sim card!!!
Why: here in Europe not every operator has the same frequency for their mobile data transfers. That means, when you have a sim from a provider with has only 2G/3G and you have configured your phone to WCDMA, the phone is searching all the time for this frequence and does not find it. Fact is, the battery sucks continuously.
So, when you are using the other sim which supports WCDMA, the phone finds it instantly and the battery does not suck futhermore. That´s it.
Change the sim. Greets.

I checked with frequencies its the same as my second sim, really dissapointed about this
draining fast on WCDMA mode its cause your area having weak signal for WCDMA of your provider, i have same problem with you, some providers in my country having weak signal for WCDMA mode only at my home area. Your phone will try to search again and again to get stable signal, that action causing the phone working hard and use more the battery power.. So maybe the best choice for you is use the second provider sim card or use the primary provider but running on 2G mode to get stable signal.
no bro i'm having perfect signal on 2G and 3G both, does it has something to do with fast dormancy? i read around that disabling it will help me, can anyone tell me how to disable it?
Hi guys!
Around 2 months ago I started having some issues when connected to the 3G network. Most of the times, it didn't transfer at all and my network icon was with the "!" sign.. I was on PAC LP and I blamed it (or some software-related cause). However, if I marked "Use only 2G networks", it did work...
I flashed the phone yesterday. A clean, fresh and quite deep install (wipes, .228 FTF, new kernel, new ROM -eXistenZ-, etc etc). The surprise was that I still have it... If I try to connect to 3G networks I might get a couple of seconds of connection, but then it just disconnects and stays like that until I change back to 2G networks... Just in case I reflashed again, same procedure, and it's still there, even on stock .228...
I bought the phone 2 years ago (in Europe, that's why I can't use LTE here), and never had a problem like this. Of course, I'm at the same place with 3G coverage (other phones do work), I've already tried different APNs, providers, etc, so I hope not, but I'm starting to think this could be related to a hardware issue...
Does anyone have an idea? Is there any software part that is not changed during a flash and could be responsible? Or maybe how to rule out hardware or software issues? This happened while I was on PAC LP, stock .228 and eXistenZ...
Thanks in advance!
It could be many factors involved - one of them could be that the operator you are currently connected (ex. Vodafone, At&t) maybe changed all their antennas in your area from 3g to 4g, and that would result in your lack of connecting to 3g.
I once changed my operator because it had better offer and then I regretted it since the connectivity was worse with the second operator and would constantly switch from 2g to 3g to 4g, all this with a major impact on battery life.
It could be also hardware related, but I wouldn't bet on it. Try checking with another phone with the same sim in the same areas to get an idea what it might be.

Hi aaronkatrini.
Thanks for your answer! However, it's not my operator's fault:
- All other phones in the same area do work.
- Other operators (other SIM cards) in my phone have the same issue, so I guess it's related to my phone, software or hardware...
I haven't checked yet another phone with my SIM card, I could try that to rule completely out the SIM card/operator's fault.
Thanks again!
