[Q] Losing Sim Card connection? - Focus General

all the sudden about a week ago it seems like my sim card is not connedted to the phone. It doesnt say no sim but it seems like it loses all connection and the batttery needs to be pulled for it to connect. its very strange. I am running pre-mango 7712. I am going to flash back to 7004 to see if the problem still exists. Has anyone else with this phone (att) rev 1.3 had any issues where it seems that the sim card isnt connected? or maybe just the Antenna is lose inside? my phone has never been dropped. It slid out of my pocket when i was driving once but that shouldnt have damaged any soldering inside.

my phone did that and it turned out that the contacts under the metal plate where the sim card slides in had broken off somehow.
but mine said no sim, so maybe you have some other issue.
as for my problem, after samsung fixed the phone, i haven't had any connection or sim issues on nodo, premango, or mango.

Yeah my phones not saying no sum. It is just losing connection. Like I have it charging sitting on a table and it will be fine. The I will pick it up use it for say 20 minutes. Then next thing I know there is no service. Battery pull, take the sum out put it back in power on and its back to working. Idk its very frustrating
maybe I should call at&t. I still have a few months on my waranty

well ive run out ideas i put my wifes simcard in to see if maybe it was just my sim and hers is doing the same thing. my sim is fine so its definitley the device. right now im actually using my good ol' samsung epix. gonna call att in the morning to see if i can get a replacement. or i might have to send it to samsung (hope not) i have flashed back to 7004 to see if it was some wierd bug. its not. it seems like the phone gets hotter than usual too. first noticed it the other day when i was using the maps at the state fair i kept losing signal and it was very hot in my palm. like i said before ive never really dropped this phone. its never got wet. im stumped.

looks like a hardware issue, hopefully att will swap it out for convenience, for my issue, i had to mail it in to samsung, who took about a week to get it fixed and sent back, it was actually a pretty pleseant experience.

Yeah that's what I'm thinking. I was looking at it this morning and it kind of looks like the solder is loose where the pins connect to PCB. Wierd how this could happen its not like I swap out SIM cards all the time. After wiggling the whole simcard slot about a tad it seems like its holding up. Well see over the weekend.

i´ve been having the exact same problem so maybe is a software problem and not hardware my info is this:
im in a re 1.3
SGH-i917
SO VERSION 7.10.7712.60
FIRMWARE 2103.11.3.3
HARDWARE 3.1.0.7
BOOT 5.3.1.6
tell yours and see if is a matter of hardware or software

No it was hardware problem for me.
The guy at ATT took the phone apart right in front of me and the charger port fell off the PCB. It was a refurbished phone.

so tech service help u, im asking becuse im in colombia so i cant send my phone to at&tfor tech support so i have to take it to a local cellphone tech shop, what was the diagnosis in yours so i can give a guide to help fix mine

Had a similar issue with my LG Optimus. Didn't see any SIM. Turned out to be software corruption, works just fine now after reflash.

SIM CARD Stuck inside AMEO! help

I have been having a battle with T Mobile ever since the day i got my ameo. I was having a problem getting the sim to register so after looking at the little picture of the simcard with the arrow under it I gently pushed it down a bit thinking it may 'Click' in like a memory card.
Unfortunately the simcard just kept moving and literally slid past the reader directly into the phone! and could not be removed.All you could see is the top edge at the bottom.
T mobile have said it was MY fault and voided my warranty but surely NO PHONE should allow this to happen.
A private phone repair shop has removed the simcard and said that nothing was broken inside the phone so therefore there was nothing in place to stop this happening.
I phoned HTC and the guy said that he could not push a simcard into the phone when he tried.
Has anyone else had this problem?
Has anyone got any advice on what i should do?
Its so annoying surely it is a manufacturing error to allow a card to go into a phone!
My first Ameo wouldnt recognise any sim. I returned it and got a replacement.
If the sim is out of the phone now and its working (ie, you can put it in so it works) dont worry. If it still wont work, just report it (but dont mention it going inside) as a broken phone, DOA. They will replace if its brand new, they HAVE to directly replace it up to 14 days after purchase.
this all happened 30 days ago!
the phone has been to tmobiles repair people and to this private firm who have removed it.
its a long long story
i dont want anyone to mess up their phone but i would like to know if anyone can push their simcard past the sim reader.
I am going to argue that it is a manufacturing error not my fault as the HTC tech person said his ameo/advantage would not allow this to happen.
IMHO The Simcard holder is absolutely awful in the Ameo. Its not entirely obvious the first time which way in it should go and I found that it will take a card the wrong way (upside down). And once its in, its pretty darn hard to remove it again. Just glad I've not had these issues.
First - if the problem happened in the first 14 days (never mind how long ago that is now), T-Mob should replace it. I have found you have to argue with them but eventually they give up.
If not, did you not get the T-Mobile insurance? If so, make a claim for accidental damage?
i didnt take out insurance, so i guess i will have to argue my case.
i should get it back today so i will take it from there.
my missus even offered to join TMOBILE so i could get another phone as my bday present! but thats gonna b a last resort.
Basically the phone should not allow this to happen IMO

I agree - and it is an odd design (as is the flap which covers the relevant slots). Good luck.
well looks i have have had a result!
I got it back to day and its now working , however its a bit scratched
Tmobile are going to replace the handset!
Glad to hear they are finally doing the right thing. I was going to say, persist.
But its sorted now, so you can finally relax and enjoy your phone.
cheers for that chaps i was getting a bit stressed about it all!
i have been streaming live Tv via ORB on my high speed unlimited connection , SUPERB!

Desire HD reboot problem

I was very happy yesterday when I picked up my brand new Desire HD. When I got home I immediately removed the plastic from the battery, inserted my sim card and plugged it in the charger while reading the manual.
After some tinkering around it suddenly rebooted. I thought it was just due to a setting I changed so didn't think much of it. However, it occurred another time later in the evening. This morning when I woke up, I didn't have any signal due to my DHD not recognizing my sim card any more. When I rebooted the phone, all was well. However when riding my train to work I felt the phone vibrate so I picked it up thinking I had a new text. Wrong: I was staring at the boot screen yet again.
When I got home this afternoon I did a factory reset using the phone's menu and hoped it would solve my problem. Unfortunately, when I opened the browser it rebooted again!
So, is my 2 day old DHD really dead-on-arrival or is there something else I could try? Unfortunately this was the last model left at the store where I got it from and they didn't know when another shipment would come in, so I might be stuck waiting for a while if I really do need to get it exchanged for a new one.
Mine is also doing this, also when I turned it off last night to charge it, it kept turning itself on. Any help much appreciated.

imo take it back if a laptop or anything else was doing this i would say there is a hardware fault bad chip sample or something its not normal you should have to live with it take it back asap
or wait if you want but personally you pay that much you want it to work just take it back
Maybe your SIM card is old and causing these reboots? DHD will automaticaly reboot when you unplug your SIM card without shutting it down first so maybe it's just loosing contact.
I've seen cases (various manufacturers) where SIM card would cause hangs, reboots and such. Replacement card from the operator in most cases fixed the issue.
My Nokia 6630 has that issue, it says the phone has to be reboot constantly due to a old scratched sim card, if i try with a new one it works perfectly :|
http://forum.xda-developers.com/showthread.php?t=676402
These reboot issues are a problem with the Desire, Nexus1, EVO4 and now it would appear the DesireHD. For the other phones the solution is to return to HTC for a mainboard replacement.
I really hope this isnt the case for the DesireHD.
As for it being my sim card: I doubt it as it works fine in my old phone (Nokia N900) and an old Motorola I still have. The sim card is barely 1 year old btw.

Yeah, I read about similar problems with the Desire and Nexus One but hoped the problems would have been solved in the DesireHD as I hadn't seen any messages of this problem occurring on the DHD before.
When I woke up about an hour ago, I again had to reboot my phone as it didn't see my sim card anymore. I'll go back to the store in about an hour to get a new one if they have it, and let you know when I get back...
This is just a wild guess, but may you should try to take out the sim card and place it back again. There could be a loose contact, dirt on the sim or some something else that might be causing a problem the phone does not see the sim correctly.

I thought of that last night so I took out the sim card as well as the battery and placed them back again. This morning, the DHD again failed to recognize my sim card so that problem wasn't solved.
The reboots seem to be rather random though, it's not just when I use my phone very heavily.
the issue with the sim card isnt the mainboatd issue, its can be sim or one of the back covers, wird.
Well, I went to the shop this morning to replace my DHD for a new one. The shop I got it from didn't have any in stock anymore, so I had the choice to wait until next week, or go to another shop and have it exchanged there. So I went there, and they replaced my (I think) faulty unit for a new one
So far, it's working like a dream What I noticed that with my previous DHD the charger would buzz very slightly when charging, this doesn't happen with my new unit and the same charger.
I'll keep you updated whether or not my new unit is indeed problem free.
I bought my Desire HD from the T-Mobile shop yesterday. Nice phone, but mine is rebooting every 5 minutes more or less. It seems to reboot soon after the 3g becomes active, but that may be just a coincidence. It also reboots immediatly upon plugging in the USB cable. Very annoying!. I thought I would try resetting to factory default, but that also did not help. I am going to swap it tomorrow, and hope I have better luck with that one.

Same issue here, got mine from three UK yesterday.
Brand new SIM Card with the phone as well.
It was fine most of last night, rebooted once then after setup, like another post didnt think that much of it.
Then this morning it went in to a boot loop, rebooted about 5times in a row and the only thing to correct was a battery pull.
Lets hope its a software issue and not hardware related!
I haven't been able to test my new unit properly just yet. I ordered a new SIM card through T-MOBILE but it hasn't arrived yet. I'm now using my DHD without a SIM card and it has been working fine for the past 24 hours. So I think my SIM card is indeed the problem, as both units rebooted several times with the SIM card inserted but work fine without one.
When i picked up my sgs. It used to have same problem. Everytime i open a browser it reboots. But after i changed the rom it went perfect
Factory reset wont work. Try fresh install from the recovery menu. I think it will fix ur problem.
Most of the time this issue is software related.

Replaced my DHD at T-Mobile
Hi all,
So i was experiencing the reboot problem on my new phone. In fact mine was rebooting every 5 to 10 minutes since i took it out of the box. I phoned HTC to see if there was something I was doing wrong. They told me it's probably mainboard fault and I should return it.
Today I brought it back to the t-mobile shop and they exchanged it for a new one no questions asked. I demonstrated to the sales guy how it reboots for no reason, just to prove I wasn't crazy, but he didn't even ask for proof. The new one seems to be working flawlessly so far.
Here in Netherlands, you have 8 business days to return your device if something is wrong, and they will exchange it. If you wait too long, you would have to send it for repair under warranty. If you are having issues such as this, I would definitely swap it out a.s.a.p because when you buy an expensive phone like this, its meant to WORK!
I noticed something else perhaps worth mentioning. When the first phone package was opened, the plastic piece protecting the battery was not there, and the Micro SD was in the box, but not in the phone. The plastic cover was on the phone however, so I didn't think anything of these things because i don't know how the phones are packed. When I got the replacement phone, I tried to start it and it wouldnt start. Only then did I realize the replacement phone had a plastic protector around the battery which I first had to remove, and the micro sd was already in the phone. When i put my sim in the replacement phone, the fit was tighter as well. This all seems rather dubious to me. Perhaps someone had a play around with the first one before selling it? Maybe it was refurbished? In any case MAKE SURE you inspect the phone before leaving the shop, and make sure your phone hasn't been played with.
good luck everyone!

Horrible reboot
Hi all,
I have been experiencing different reboots due to different reasons. Main reason is the fact of applying too much pressure on the back cover. That will always result in a reboot (I suspect it has to do with the two contacts under the cover).
Another reason for rebooting, as I have experiencing, is unplugging the charger while using the telephone.
I wouldn't be surprised if there are more reasons that cause the rebooting of the unit.
The worse part in my case is the fact that I lost the receipt, thus I believe I won't be able to take it back to have it fixed. Am I wrong?
I've been experiencing the same issues, but mine also turns itself on. I tried factory reset, didn't solve. So I am getting it exchanged as soon as its back in stock with Vodafone.

I am having exactly the same problem with my DHD. It's randomly rebooting 1 or 2 times a day. And when it's rebooted there is no signal and sometimes it doesn't even recognize my simcard at all. Manually rebooting the device then solves the problem for a while, untill it reboots automaticly again....
I have a dual simcard so today I will swap it, but I don't think that is going to work.
I don't have the DHD yet...
But i saw in a youtube movie that the batterycover had 2 contacts.
The guy in de video told that when you take the batterycover off when the phone is on it will shut down.
Maybe your battterycover is not set the good way.

HELP Need Advice, SIM not working

Earlier today, some water inadvertently spilled on the back of my G2, it wasn't a lot but I did turn off the phone, remove the battery, tried to dry it, etc. Phone seemed to be working fine (probably shouldn't have turned it back on in retrospect) but I soon noticed I had no service, removed the SIM, dried a little more, re-inserted, it came back, only to die again soon. Haven't tried it in a while, I currently don't have access to another card to try or another device to try my card in. When I get home, I do have an extra sim that came with my G2 as well as my old G1.
I think what I'm going to do is try to use my SIM with the G1 and see if anything happens, if it works then there's definitely an issue with my G2 sim reader, if not, then I can just try my new sim with the G2 and hopefully that will work.
Do you guys have any advice? My G2 is a little over a week old (~10 days)...I know T-Mobile warranty does not cover damage. However, it does not really look like there's any damage to the phone (literally everything else works perfectly). Would it be possible they might just consider it a malfunction and replace the device? I think in the worst case, I could probably buy insurance (still under 14 days) and get it repaired...
My main question is, should I try out the new SIM in the G2, or wait another day or so? This has been stressing me out for the last few hours....

[Fixed] "No SIM Card" after Hardware GPS Fix

Well, I gone an' done it. After doing the hardware GPS fix (no soldering, just carefully bending the contact a bit) my phone will no longer detect my SIM card. The SIM card itself is functional - I tested it on an old backup phone that I had handy - but the Vibrant no longer detects it. Everything else works - power, wi-fi, etc.
I've reflashed the ROM and Kernel, and I have yet to odin back to stock and test the SIM card in that state. I'll try that tonight.
Close visual inspection of the internals doesn't look like I broke anything. I'm fearing I may have shorted something while I was doing the GPS fix. Are there any other options that I might want to try?
[edit] I'm on ICS Euphoria RC1 with Kiss v2.2
Check your imei by going into about phone in settings.. compare that with the one under your battery. If its different, odin should fix.. if not, kill yourself... then check around the sim card housing to see what you f-ed up...
Luckily, worse case senario is you end up with a samsung galaxy player (or whatever its called)

imei matches. Sim card housing appears intact. I do think I zapped something in the process... Oh well. I'm about a month and a half til I can upgrade. I suppose I can live with a flip phone until then. Or I could just kill myself.
They will both solve the problem equally well....
I would still odin if you can...
Zapping something isnt really that common in working with electronics....
I know it sounds obvious but are you sure youre putting the sim in right?

I opened her up again and found a loose connection from the SIM card housing to the main board. The connection is hidden behind the board so I missed it the first time around.
Reconnected it and my SIM card is detected once again!!!

SOLVED: OP6T no network (Coaxial connectors)

Its rare that i have an issue i cannot solve on my own, but this one has me stumped. last friday, i took the newest update on my OP6t 8/256 to 10.3.10 (unlocked, bought from OP directly). After the update, i lost cell service.and signal. i am bootloader unlocked, and eventually ended up using msm tool, which did not resolve my issues, despite wiping and relocking my device.
now, i am back on 10.3.10 and i only have some service when i am on wifi. i have cleared network settings and also manually added Tmob which errors out. i have tested the sim in my old Axon 7, and it works perfectly. also, the settings menu appears to show another update still, but it is not clickable. anyone have an idea? Thank you in advance for any help!
On that last screen where it shows your MAC address does your phone still have a IMEI ? (Don't post it, just it should have a number, yes or no?)

It still has both of them. (Dual sim). I have an axon 7 that lost it's EFS partition, so of course that was one of the first things I looked at. Having had that happen before, that was one of the first things I backed up when I got my fajita in 2018.
well, even a new sim card did not fix whatever has gone awry....
update: i took it apart, and pulled the shield over the board. tapped around. put sim in, it didnt work. rebooted with the sim still in and it worked almost all day. set it down on my desk, network disappeared again. pressed on the back just below and to the left of the camera hump, and it came back. worked for 5 min before stopping again. picked up a op9. but i will attempt to fix it later down the road. im guessing either the antennae is loose (checked all coax to ensure they were seated) or one of the multitude of drops, albeit in a good case, broke something beyond repair.
Update: after ordering a new sim reader and evaluating the phone some more, I realized the signal antennae was on the verge of breaking. Moving it with a nylon spudger finished the job.
Update 2, replaced snapped off gray coaxial and still had no network. Realized the other coaxial connector had popped loose and felt like it was seating, but it waant. So issue resolved not at all the software. It was the other coaxial connector. It felt like it was seating, but was not. Fixed and working well now. Woot. Thank you anyone who helped!!
