My cell phone's functions work properly except for the phone itself. When I turn on my cell phone it keeps saying "searching" for a while and then "no service" appears. What might cause this? Thanks in advance
Your cell is not able to receive signals?? A little more info needed, are you using stock Radio and ROM?? If not, is your radio compatable with your current ROM??
It could be a function of not using SEARCH first...
Or, it might be corrosion on your SIM card. Pull it out and rub it lightly on your jeans, or use a pencil eraser to clean it off, then stick it back in and see if it gets signal.
Try searching for a network manually, see if you see any (even not the one you have your contract with).
Test your SIM in another phone.
Test another SIM in your phone.
Turn off 3G.
As said above, if you have flashed the phone make sure the radio is comptatible with the ROM.
If all that fails, send your device for repair.

recently bought a htc diamond from a market stall which i think was a mistake!!! he said it was all working and put my sim card in at the stall which the phone turned on and everthing seemed to work, on closer inspection i have no signal the internet works i take it the gprs is still running through my sim but i dont recieve calls / make them or texts due to the fact i have no signal!! ive tried updating the rom with the one from orange website that works but still have no signal, now i like the phone so was wondering if there is a rom / hacked software for the phone that unblocks it? i dont mind having h#dodgy software on it as my contract runs out soon and will be getting a new phone anyway just need this one to work for the time beeing!!
Not too sure, there is a few things that could be wrong.
Broken antenna?
Software problem?
Blocked IMEI?
just checked the imei number currently unblocked so its not that!!
try another simcard older sims are not always compatible
but most places operators send you a new one for free if you "lost" it or broke it
Didn't you try to make a call before paying for it? I hope you didn't pay too much!
From what I read in the first post, it seems as tho you say the internet works?!? Do you mean cellular or Wifi Inet? If you have cellular Inet then you have a signal! Cellular Data cannot be transmitted if there is no signal.
Take a look at the antennae: There are two "sticker" antennas {1 above & 1 below the battery} Remove battery cover. At the top of the device is a sticker antenna that is for the Wifi & Bluetooth. At the bottom is a sticker antenna for the cellular radio. If the sticker looks damaged then that is your problem. Also check to see that the Void sickers are still there {there should be two; 1 above & 1 below battery}. If not then someone has opened it & possibly damaged the antenna. Don't forget to look at the LDI {Liquid Damage Indicator} located under the lanyard hook while you're at it.
You can also try flashing with a different Radio. Read the Diamond Radio thread in Diam ROM Dev.
My Nexus was on 5.0.41, all working sweet, then it stopped "finding" the network. No update, flashing or anything was done prior to the problem.
I tried a SIM from another provider, but still - the "No Service" is written on screen, and when I try to search for networks, it says "Error searching for networks".
I then tried the following ideas (nothing helped):
- Reflashed the Radio image.
- downgraded the Radio image.
- Upgraded it again.
- Flashed the Stock ROM (unrooted and rooted).
- Flashed CM5053.
All was done with wipes as needed.
Any suggestions will be more than welcomed!
Can the device just get bricked like that? with no reason?
It sometimes identifies the SIM's provider (Orange for example) but always with No Service.
It sounds like your SIM card slot isn't holding the card in tight enough to make full contact... try putting a business card, cut down to size, between the SIM and the phone's frame (note, not the contacts side, but the back side) to force the SIM down onto the reader tighter.
If that does nothing, not sure what to tell you?
it didn't help
I'm Italian and I have the same your problem .. I only work in 2G GSM'...ve tried to see if you do so?
I opened another tread here Forum
You need a new SIM.
I just had this problem on Friday. The SIM some how falls of the network and your provider network will not allow it to reconnect.
I can't remember, but if I am right Orange is owned/owns by T-Mobile. Hence they have the same network.
The puzzling part about this is why it happens. This is the second SIM I have gone through with my N1, I also had one go with my G1, my sister bought that G1 and the SIM went out again. My mom bought her G1 same day as me and hers has died once. My friend has a MT3G and his has died two times now. I find this extremely annoying.
I tried every suggestion on the internet for repairing or troubleshooting a SIM. It is a waste of time. Well, everything short of dropping it in isoproply alcohol to clean the contact.
I tried a 2G and a 3G SIM on mine, and had the same result, so my problem is different.
My device just doesn't register with the network, no matter what provider or SIM generation I choose.
Can I ask for a RMA if I unlocked the bootloader?
I do not know you definitely do not pass it under warranty
Ryan then you say you clean the contacts of the nexus or the sim with isopropyl
Mine is now doing that as well and so far everything that I tried isn't fixing it. I get it to connect briefly with edge and then nothing. I am going to try a new sim tonight after work and see if that helps, otherwise unsure of what to do after that...anybody got any answers or suggestions?
I've been suffering from this... have an RMA coming but I got mine to work. Make sure you also have CDMA preferred on there or whatever the default is. If it says unknown you have to reboot the radio somehow. I pulled my battery, waited 5-10 seconds. Then i went and checked airplane mode on and off. Then i checked the service menu again. I can't remember if i had to pull the battery another time but it came back from "unknown" to cdma preferred. You can also try turning the radio on and off via the service menu. Finally select your radio bands for your region by pressing the menu button under phone information again in the service menu and select radio bands. I'm not sure if automatic is a good or bad idea but it couldn't hurt testing it if you still have some issues even after selecting your region specific bands. After this you should be able to maybe search and register or you may need to turn the radio on and off again via airplane or the service menu. I played around with it alot to get it running again.
Also I'm tmobile usa using the one for t-mobile bands. I'm not sure if CDMA preferred is a world wide setting or if its gsm or something else.. but the bands are specific to your region definitely.
Hi Folks,
how in the topic, im loosing my signal at point where my signal is weak. if i lost it, i can run around to get it back to write messages or call someone. it doesnt work, because my phone say's "only Emergency calls". i wait one hour but the phone can't connect to my provider. The radio is at the moment 32.36.00.28U_4.06.00.12_7, i've already tried newer and older version of the radio img but always the same issue. From the beginning when i had the phone, it sometimes doesn't regognize my sim card, i have tried everything to get it to work (new rom or radio img) but always it fails. on the next day without any changes the phone works again with the same sim card. So now here is my question....... what the HELL can i do to bring it back to work, so it dont lose the signal in weak areas, and if the phone loses it, what shall i do to automaticly reconnect the phone automaticly to the provider. and airplane mode is no soloution for me. thanks for answer.
Have you tried another SIM card in there to see if the problem still occurs?
Sometimes the card itself needs replacing. Just a thought..!
this i havn't tried out yet, but i tried my actual sim card at the phone of my wife and it works a whole day without connection lose. I'm just thinking its a software problem maybe its the wrong radio version.
No "wrong radio version" will lose connection and fail to reconnect.
It's either your ROM or (most probably) HW problem.
You can try to wipe and install a clean ROM and see if the problem persists. If it does - use the warranty.
which rom would u suggest ? I tried CM6 / CM7 / MIUI nearly all modded roms here. The problem is to try out if the rom works i have to go out to a point where the signal ist weak, and hope for a signal lost. Sometimes it works and i get a reconnect to network and sometimes it doesn't work. in zones where the signal is strong i haven't any trouble. Did i get any problems by HTC if my phone is unlocked? I already had it gave to a repair 3 month ago with a broken usb connector and there was no trouble with warranty at unlocked phone but what is now? can they change their opinion ?
I got it. The Problem was the the Phone has to set the Network search to manual and not to automatic search. it works now for over 1 day and it seem that is now no problem with lost signal. Thanks for Help. But i just wondering why i have to chose manual network search an not automatic.
Hello I'm having difficulties with my i9000.
The problem first started when I smashed my screen. Bought a replacement screen and middle plate frame bezel, including the home button flex cable. I also unfortunately damaged the loud speaker and thus replaced that also. Now everything is installed and the phone works great except for connecting to a network and making calls.
When I dial a number I get "Mobile network not found". When I check available network it finds my network and attempts to connect. Then I get a message this network is not available for this sim card, or something along those lines.
The sim card works in another android phone and other sim cards gives the same message.
The IMEI is intact and correct.
The phone is unlocked
I started on 2.2 and have flashed the firmware with many different types and still with the same message.
Now my question is this, how would changing the screen, middle plate & loud speak have this effect on the phone? Bear in mind that the phone still functioning with the cracked screen and making calls.
If anyone could help put me out of my misery it would be most appreciated.
Try flashing different modems now !
I'd say you might have disconnected a cable or forgot to reattach it. However, that might not explain that you do see the network sometimes. So yes, modem's probably a safe bet.

Ok I'll try this, not quite sure how the changes I made would effect the modem.

All cables have been checked and triple checked, and the network is always visible to connect to. Thanks for the advice I'll try the modem, is there a particular one I should try? I'm in the UK and my phone provider is 3.
Tried various different modems, giving sometimes better signal quality and sometimes worse. None of them have any effect. The message i get when connecting to the network is "your sim card does not allow connection to this network". Which to me sound like it may be locked again. So I'm going to try and dig out the original sim card and try that.
Try some other network and check !
Tried other networks and still no joy. I've flashed it many times now, gone back to stock firmwares and nothing will work. Spoke to Samsung and they just tell me to plug it in to Kies, which does nothing. I'll take it to my nearest Samsung service centre and see if they can fix it.
1. In security remove SIM pin request at restart.
2. Reflash MODEM with odin
3. At searching network check (automaticly)
Hello.
1. There is a mi 3 phone with a symptom that does not see SIM - but all Sim-connector are in place and removing back panel does not show that they are broken, as is typical in this device.
2. No sim tray. Therefore, it is not clear whether the slot is faulty or some contacts are simply not closed. I saw one "foot" at the bottom of the slot, but it did not respond to pressing. Anyone who has tried or knows, plz tell me how the phone detects whether there is a SIM card or not?
3. Already the most incomprehensible. On 911 the phone does not catch anything. I beg you, please look at your device. pull out the sim tray and just dial 911 will connect or not. no need to wait for an answer =)
4. What does a GSM antenna look like? She's not in the plastic insert on top of the phone or the cover?
in general, need to understand what to repair! is the radio module dead ... (by the way, how to test?)
However advanced phone technology may be, the ability to make or receive phone calls remains the most critical feature of any mobile device. To be without this basic telephone use is to get the message "SIM card not detected" on your phone. It goes without saying that this is a frustrating situation that needs a quick fix. So, if you're not sure what to do in this situation, we've compiled a list of seven expert-recommended cures for you to attempt.
what you talking about?.
General question is - how PHONE detect sim card? by software? hardware switch? Shorted PINS?
