Get a new sim card?

Does your sim card work in a different phone?

That happened to me once. I had to return the phone. I was unable to get it to recognize the sim card.
Different rom didn't help either. Even when I flashed back to stock... no sim. It was a refurb so a new one was easy to get.
Hope you get it worked out.

This happened to me earlier this week. Flash to stock and then back to the rom worked for me

Clean contacts on sim card. Factory reset. If that doesn't work call Rogers for replacement.
No warranty you can replace the simcard slot its a daughter card I think you can order from globalpartsdirect

I have the exact same problem. Again it happened with a warranty phone I just received today. It occurred while trying to root the phone. The SIM card from my wife's iPhone does not work in my phone either. However, my SIM works in her phone. I've tried just about everything I can think of at this point other than running Kies (my next try).
BTW,
Unlike my original Captivate, this one came to me with Froyo already installed.

Under Menu /Settings / About phone /Status /Network what does it say ??
If it says "Unknown" you could try just flashing ur modem again.

I am having the exact same issue with a refurbished phone from AT&T and insurance gone im out of luck unless there is a easy solution.

Hello Everyone, So this is my situation so far:
I have a Samsung Captivate with unbrickable mod added. I flashed with Heindall to 2.2 froyo on linux. The SIM card is not recognized. I have triend 2.1 and 2.2 and 2.3 one clicks in windwons with no luck. I tried to mess with IMEI and elfs file. Results were that the lines i was suppose to change on nv.bin did not exist (no lines in file i was attempting to correct). So at this point and time can i conclude this is absolutely not a software issue? Problem two is if this is a hardware issue and not a software issue. Where do i begin? how much is the price for replacement? How hard is it to do? I have tried flashing with everything off the phone (sim and sd) Im a bit lost at this point. Any help would be great.

Update: Spoke with Adam and he says its not a software issue. I also spoke with the guys who did the soldering and said the issue is not coming from the soldering. I am thinking maybe when the phone was taken apart something got loose? Any thoughts anyone?

[Q] Emergency calls only

(SOLVED)
Hello,
recently, my O2 sgs will only stay on "emergency calls only" in all different areas where it used to have signal before. I've tried to manually select the network and even though O2 is available, it doesn't connect (register) with it and says "unable to connect, try again later"
tried many different roms, differend modems, but no luck. fed up.
can anyone help me please?

modem problems

i've told that i already tried many different roms (cm, ezbase, miui...) and modems

I had the same problem with CM7 before after installing if GApps (Google Apps = Market, GMail, Youtube,...). Then I booted into recovery, wiped cache and Dalvik Cache (didn't help) and finally I chose 'fix permissions'. Now everythings is okay again.

have tried, but still it stays on "emergency calls only". what's weird is that it even doesn't call any emergency numbers (says out of service area)...
desperately need help with this, or should i just give it back to the o2 shop... android is the biggest pain...

But the SIM is inserted correctly? Have you tried another SIM? Maybe your SIM-card is defect.

ok, i had another t-mobile sim in my phone and it is working ok. but the o2-sim will not connect, even though it works on other phones well.
what's wrong???

Call O2 and ask vor a new sim because this one probably is damaged.
They'll send u a new SIM for free. I had a similar problem with a dual sim of t-mobile.

Is your phone SIM- or netlocked?

same problem here....suddenly it went emergency call only.have to reset and only then can get the signal back.it really pain in the neck
Mine is GT-i9100 btw

[Q] No service / No sim card

A. Introduction: I had the HTC Desire C working smooth and fine. Then one fine day, I realized that the microphone is not working properly, the person at the other side of phone call would not be able to listen to me unless I'd literally shout over phone. So I gave the phone to the HTC service center because it was under warranty. They changed some parts and handed back the phone to me. But the problem was still there. I again submitted my phone. They changed the same parts again and now the mic was working classic, phone was working smooth.
B. Twist in the scene: Just after few days, I was on my way to home after some work and I noticed that phone had a cross (x) against the signal and when I pulled down the notification thing, it said NO SERVICE. This used to happen a lot of times from then onward. Switching to Flight Mode and then reverting back (OR a restart OR a sim pullout and insert again) would sometimes fix the issue, but only temporarily. Sometimes after reboot, it would say NO SIM CARD, sometimes NO SERVICE and sometimes proper functioning with 2-3 bars.
C. Attempts from my end: I thought that they have messed the sim card slot while assembling my phone back and it is a hardware issue. But I was finding it hard to believe. I tried switching to GSM ONLY, then it would show full bars, but again only temporarily -- later NO SERVICE again.
The same SIM card in other phones (standard Nokia b&w phones aka hammers) shows full bars. And I have tried 3+ sim cards in the HTC, but all say NO SERVICE after sometime, maybe due to some activity (connecting internet) or just randomly on its wish.
I studied about radios(modems/baseband) and found that they are drivers and they also decide when and how to switch between 2G and 3G network etc.
D. Other Information and Background: Many times, when there is NO SERVICE error, when I check the Signal Strength it says -83dBm 15asu, so that is pretty hard to digest. The other times it says 0dBm 99asu, which should be obvious for a NO SERVICE error.
With point number E.2. in this post I have unlocked the bootloader and rooted my phone, installed CWM recovery, took a backup.
E. Options that are/aren't available from my perspective and my doubts:
1. Warranty period is over now, and I do not want to take my phone to the service center.
2. Can flashing a custom rom and radio fix this issue? If yes, direct me to some reliable ROMs for the same. CM10 build#3 (from here) didn't boot.
3. I have a Linux laptop, so options strictly based on Windows PC will not apply.
Has anyone faced similar issue? I found many pages with similar issue, but nowhere was the exact solution/troubleshoot mentioned.

I did have a problem with sim cards. What I tried doing is borrowing a friends sim card to see if it works on my phone. To my relief it worked and meant that my current one just died. So I went to one of the offices of my Phone plan providers and just changed it and it worked. If you can try that and give back results, it would be awesome.

Depending on the age of your SIM card can give those errors but as you stated you tried other SIMS and same occurred so my guess is it's either Hardware or Baseband Software, unless there's a Baseband update or simply reflash same Baseband, if it still persists I'd more suspect Hardware.

I, myself have a lot of sim cards to check this and I have already tried other sim cards. Some cards are not even recognized. Some are being recognized but it says NO SERVICE after sometime. Switching to Flight mode and back or restarting the phone or Going in Testing Mode > turning off radio > and turning it on again, sometimes solves the issue but only temporarily.

Probably. And that's why I installed mini CM10 and flashed the radio with the latest HTC Desire Radio (for CM), but it still says NO SERVICE and the same baseband version as it was saying with the stock ROM. :/
Even though the signal strength is -63dBm 25asu

Can you call or something if it is showing signal strength?

No, I wasn't able to call. And when I would search for a network it would say "Error while searching for networks"

I'm more likely to suspect the actual SIM card holder hardware and not the SIM Card itself or the Baseband (No errors reflashing and other SIM's no different than your own), the fact it's showing signal strengths but you're not getting onto the network suggests RADIO hardware is most likely working along with software but a hardware failure could just be 1 connection to the SIM
Q. Are all other SIM's working in other phones and does your SIM work in another phone?
If so I'd suspect the SIM Slot onwards.
Q. may or may not apply but possibly relevant, does Bluetooth and Wi-Fi still work?

Answer #1: Yes
Answer #2: Yes
Q. I still don't get that when I have flashed the radio, how is it still saying the same baseband version? Doesn't flashing a new radio change it?
Recent UPDATE: Somehow, the phone is behaving well... (always 3 bars or full 4 bars), after the mini CM flash and NOPE 750 flash. Initially it was NO SIM CARD or NO SERVICE but multiple reboots and pulling out and reinserting the sim card have made it this far. Let's see if this good behavior persists.
UPDATE: Back to the same state of disconnecting/No Service/No Sim Card

I still suspect the SIM slot as you could have disturbed what's known as a 'dry joint' essentially made it make contact until it disconnects again even with just a change in any kind of pressure (placing the cover on or placing it on a table).
Then again it could be down to ROM and Kernel, I wouldn't totally rule it out without going back to stock ROM and Kernel and seeing any change

That sucks!

UPDATE: The network seems quite reliable when I am on GSM only (2G only). That again indicates that somehow the problem lies in only the radio driver.
Any ideas?

Same Problem
I am facing exactly same problem on my HTC Desire C. Did lot of hard reset problem reappears after couple of days. got my phone reinstall OS at HTC service centre problem reappeared after a week.
Same sim is working fine in other phone, even got new sim still same problem.
Am confused if its hardware or software issue, problem comes only when phone is in GSM only mode, works fine on WCDMA only or AUTO mode.
But in WCDMA only since network is not good signals are low and in AUTO mode when signals are low it switches to GSM and if at that particular moment there is problem then NO SIGNALS.

Update, Phone fine. Help with the settings!
I checked a lot of sim cards and found that my phone is perfect! There is no hardware issue.
So I am presenting the present scenario. Please help!
I have 2 phones: HTC Desire C and a Nokia B&W aka hammer.
1. TATA DOCOMO sim card work fine on both phones.
2. AirTel sim card works fine in Nokia but HTC says "No Sim Card" regardless of the numerous attempts.
3. Reliance sim card (brand new, bought today) works fine in Nokia but HTC says "No Sim Card".
4. A friend's Reliance sim card was working fine in HTC.
If any Indian friend might help, then it would be great as this issue is more local specific I guess. Or any user who might have faced similar issue and then found a fix please help.

You tried Vodafone?

Not yet.
And believe it or not, but the AirTel sim that I mentioned in my last post was working once I washed it with some alcohol. So it might indicate that the sim was old and dirty maybe.
But what about the new Reliance sim, I just bought it today and it works in Nokia. I'd have switched to Vodafone but I can't afford its high 3G plan rates as I have to maintain an MTS MBlaze for laptop as well.
And the thing that friend's Reliance sim works fine in my phone is troubling me even more.

[Q] New Xperia Z1 No Signal Whit any sim.

Hey just got new z1 for my wife.
worked fine in 3 days then suddenly NO SIGNAL from provider.
Took my simcrad in that phone no signal.
put my wifes sim card into my z1 then i got signal
Some thing wrong whit the z1?
Have googled hole day cant find a solution plesae help me?
anybody have the same problem?
Cheers Stian

Go via Warranty.

Well same happened to me at first I though was the sim reader but it was the rom that suddenly stop reading the sim and I don't know why. The solution was to flash a different rom and now I am with kitslim. To check the sim reader I used the app "sim card by gsmdev" such app allows to read the sim information like contacts imei etc so if that app reads that info means that the sim reader is OK and you need to flash a different rom or the same. Hope this help

Check if your imei is intact, perhaps you could flash an FTF file which will replace the OS so back everything up first.
Make sure you are inserting the sim correctly (i know you probably are but it's worth checking) ones the sims in the phone it should reboot, could be that the contacts which hold the sim aren't raised enough, don't bother fixing them just take it back if that's the case, if the sim has been inserted incorrectly then theres a chance that the contacts may be bent and if that's the case then your warranty will be void, but in all fairness it sounds like a dodgy phone rather than any of the above.
I'd still do the FTF flash anyway, it's probably the best shot you've got, oh and i've noticed that some peoples phones will read sims and others won't so the fact that it works in yours and not hers although weird, isn't conclusive. Try another sim too.

[Q] No network issue LG Optimus 4x HD

Hi guys,
I have a LG Optimus 4x HD with stock rom (Jelly bean). About three weeks ago, I suddenly lost my network connection and it looked like my phone didn't recognize my SIM card. I put my battery and my Sim out and in my phone, but that didn't help. I tried many SIM cards and they work excellent on my other phone. When I turn my device on It just boots up and doesn't ask for my pin code at all. I see no difference when my SIM card is in or out my device. However, it does recognize my SD card, so I think there is a problem with the software? On the lock screen I just see the message ''no service'' and at the top I see this (first pic). When I try to dial someone it says ''reorganization of internal processes. Try it later.''. I read on a forum that I had to go to ''mobile networks'' in settings, but that isn't possible (pic 2).I also tried to put some paper between my sim card and my sim card slot but that didn't work either. Does someone have this problem too or is there somebody who can help me to solve this problem? Your help would be greatly appreciated.

I discovered that my phone doesn't have an IMEI and IMEI SV code anymore. It also doesn't have an baseband version. Do you guys know this caused the lost of my network connection and does anyone know how I can recover my IMEI number? Finally I managed to enter the mobile networks in settings by do a long tap on the data icon in the notification center. I hope someone can help me.

I have the same problem as you. With every restart the phone is unable to read the sim card. Also the baseband is shown as unknown, and I don't have imei no. The solution for me is to remove the battery, and put the phone in the refrigerator for 10 minutes.(yes in the refrigerator The phone is getting very hot when is searching for network and to have it really cool helps apparently. Try it yourself to see if it does the job for you and let us know.

Thanks for your reply! This morning, my phone finally asked for the first time for the sim password and I finally got a signal. I got my IMEI and my baseband number back. Unfortunately, after an hour or so I tried to send a sms and I wasn't able to send it. I got the error no USIM or so. The IMEI and Baseband number disappeared agian. I turned flightmode on and of and I didn't get a signal again... New today was that I am now unable to connect to multiple wifi networks too. Now my WI-FI MAC-adress is 00:00:00:00:00:00. I already lost the phone and I now also lost the smart part of my smartphone... I also tried to put my phone in the refrigerator but sadly it didn't help. I think I have to buy a new phone....

Sorry to say that "It's time to say goodbye"
I got same problem with you and try all kind of possibility. Here is final verdicts:
- Some phone repairers I know said It's the encrypted baseband partition is damaged, unless you have backup of that, it's a no-go
- I've tried to reflash the phone and it will stuck at 10%, you have to push really hard at some point at the back to make is flashable. After that, the signal back on with baseband and IMEI.... but only for a few restarts it will be gone

Hi blbterminator,
I already said goodbye to my p880 (has been replaced for the G3), but thanks for your reply. Now it's clear for me that's it's a hardware issue.
Maybe do you know if this problem only affects the lg p880 or other brands or models too?
Many thanks!
