The mobile network on my phone fails in certain areas of my University.
I tried inserting my sim in different handsets and it worked properly. I even tried inserting other sims in my phone, but there wasn't any difference, i.e, I still couldn't connect to the network.
I've been using CM 10.1 for the past few weeks and this problem started only a week or two before. Moreover, I regularly update my device to the latest update released by the CM team.
Any help will be appreciated.

If your SIM couldn't find your network even on a different phone, than you just have poor reception. The carrier's coverage of that area is poor. You can't fix that.
G'day.

I'm sorry, but I wanted to say that my sim works in all other phones, but no sim works on my device!
Sorry for the misunderstanding.

I've recently noticed a weird network bug on LFB. If the phone loses signal (on subway etc.) with data on, when signal is available it acts as though the SIM was refused by the network continuing to display Emergency calls only. If I turn data on and off it gets weirder (see screenshot).
The only way to fix it is too reset the radio, with flight mode, or *#*#4636#*#*
It's definitely not a hardware fault since, as you can see it still can connect to the network. It just acts as though the connection was refused (or alternatively does something weird that causes it to ACTUALLY be refused)
Anyone else experienced this??
The phone is an original BTU using unmodified LFB on China Unicom

Are you able to set/receive calls or send/receive SMS? What about USSD codes to your provider?
I've already read about other users complaining about this issue, I guess it's a software-bug in the display.
No. I'm not sure if HSDPA will work in the example pictured. I was in a hurry to make a phone call so just quickly snapped the screenshot then reset the modem.
Messages will get service unavailable. Incoming ones don't get received until I reset

Yes, I've experienced the same thing a couple of times since LFB on carrier Telia in Sweden.
It reminds me of the phone/modem problems with the SGN which they never fixed before I sold it.

Washington D.C. has no GSM coverage inside the tunnels. Only some stations have coverage. Only Verizon and Sprint with CDMA devices have service on moving trains.

You can flash DXLF3.. It works so much better than the LFB radio.

Beijing.
Well 2G is okay. But it sometimes will lose it briefly in the transition from 2g to 3g.
Only Beijing subway line 4 has China unicom WCDMA coverage. the others are limited to 2g at best (except the overground lines, but even they are patchy)

Having updated to the stock LFB ROM and modem (UK, unlocked, unrooted), I'm really perplexed about the behavior of the phone data reception:
(a) 2 weeks ago, I tried using data connection in a friend's flat in Balham (London), could not get ANY data connection all weekend.
(b) Last weekend, data was consistently perfect and fast anywhere in the same flat, all "H+" 8Mbit and lovely.
(c) This weekend, same place but NO reception again, not a saussage. Voice phone worked fine, just no data at all.
And, yes, I've seen "emergency calls only" sometimes even when there is apparently a strong signal.
Back home again (Portsmouth), phone works fine.
On the plus side, battery consumption is wonderfully low!
Can anyone explain what's going on? It feels like the data connection is sometimes reluctant to "log in" or whatever is does! It seems to have a mind of it's own.
Thanks!
You may want to try another modem like DXLF3. It has better data network stability especially in cities or areas with faint signal.
I am planning to upgrade to the LFB, but i am not rooted. Want to be sure if i have problems with the modem signal, do i have to be rooted to install the new modem driver??
Thanks in advance...

Right I turned it off took the SIM out booted back up without SIM the rebooted again with SIM but the signal still keeps dropping off I only get signal for a few seconds. I normal get really good signal where I am. Also battery is dropping quicker then normal I guess that's down to searching for signal though

orange/t mobile are doing quite a bit of network repairs and upgrades at the moment ahead of 4g, so that may account for it, try going networks and selecting t mobile, always get better signal like that here

I purchased a galaxy s3 international version about a month ago. The phone was working fine for about a month until yesterday, my phone is getting very little or no signal at all. also, when i connect my phone to my car, the phone will start calling itself. i performed a factory reset and the bluetooth problem was gone, but the phone is still getting very little to no signal. wifi is working fine. i called Rogers, my service provider. all they ask me to do was to buy a new sim card or remove the battery from the phone and wait. none of those helped... :crying: i'm kind of desperate here as i can't figure out what went wrong with it... my phone is not rooted or anything... if someone can help me out, i would really really appreciate it. :crying::crying:
Unless you are willing to start flashing modems to your phone there isn't much we can do for you.
Best bet is to keep pestering your carrier if you don't wanna root and modify your phone.

thx for the quick reply. So rooting my phone and flash a new rom is the only solution? :crying: is it possible it's hardware problem?
Not a Rom, not before trying modems anyway.
It may be hardware related, you should keep pestering your carrier for a replacement.
If it world fine before then chances are its a hardware issue or the cell tower near you is down.

Did you try with a SIM of other network? This may at least point out that either it is network problem or hardware problem.

I don't have another micro SIM... I tried flashing different modem and firmware. But none of them works... the phone is connected to the network, just the signal is extremely low all of a sudden... I had an software update 3 days ago, maybe that's why?

I was just wondering if anyone has successfully used a dual sim adapter of any kind with a stock note 2 or one running any rom ? I purchased a magic sim adapter for my phone and it doesn't seem to work. I've restarted the phone and put it in airplane mode and nothing changes. It just says no sim searching for service. I have tried both stock and on jelly beans rom v8. Ive tried with two verizon sims and also with att and a tmobile sim. Thanks !!
What is the purpose of having two sims at the same time?

This is pretty popular in other countries. Usually for use when calling places with different rates, etc. For better rates on phone/data, etc or if you travel between bordering countries, etc.
I've seen a phone(not note) with 4 Sims in use before.
As far as Verizon, sorry man.... Not for sure you can without some heavy mods. Hopefully someone else here sees your thread
I have a sgh-i527m (Bell) which got unlocked. I tried a few custom roms but went back to this stock rom since I wanted full functionability.
Periodically, I would get the "no sim card" error. A simple reboot or re-insertion of the sim card usually fixed this issue but earlier today, It just clunked randomly and no matter what I tried, I could not get my sim to work (Fido). I even went to Fido and got a new SIM, since my sim was so old it wasn't even the LTE sim. And still no luck.
I even tried using the scotch tape Nexus fix, still nothing.
I tried re-flashing stock rom, no luck. Going to try a nandroid backup.
Also, my friend's SIM works fine, which is Rogers but my Fido sim won't work yet my Sim works fine in his phone (unlocked i9500). Ironic, because Fido uses the Rogers network..it makes no sense.
Somebody shed some light please?
Have you tried flashing a different Baseband to see if it improved? I have heard issues that on some networks with Kitkat the software has trouble switching between 2g, 3g and LTE and this causes the sim error because of registration issues on the network.

I never had the sim error on kitkat though, only stock rom.
Anyway i think i figured out the problem. My simtray is broken, pins pushed all the way in.
