HD7 Invalid SIM - HD7 General

I am working on a friend's HD7 locked to US TMO running stock US TMO Phone 7 ROM. A few days ago it suddenly started getting "Invalid SIM message". It is out of warranty coverage.
Swapping out for a known good TMO SIM it still gets the Invalid SIM message and his SIM works fine in another device so it doesn't appear to be SIM related.
I performed a hard reset on the device but it still gets Invalid SIM so it doesn't appear to be software related.
Suspecting hardware, I did a lot of searching of xda-developers and google for possible solutions.
I found this: http://forum.xda-developers.com/showthread.php?t=1127798 so per that thread I took the device apart and cleaned then reseated the SIM slot connection to the main board. It still gives Invalid SIM error.
I found references elsewhere that it might be due to the SIM being somewhat loose in the SIM slot so I shimmed it with a piece of paper, yet I still get Invalid SIM.
I'm not sure what direction to go from here. Has anyone ran into this and been able to fix it successfully?

A couple hours after posting the above, I noticed that the error message was gone and the device was connected successfully to the TMO network. I have no clue why. Hopefully the issue doesn't happen again.

This exact same issue happened with my T-Mo HD7 too.
I'm in Australia, and bought the phone off eBay brand new with an unlock code. I used to be with three (a dodgy network provider), and got a couple of new sims, with no avail. With a reboot though, the message would be gone.
Since then, I have changed network providers and reset the phone a couple of times, to find that I no longer have the issue at all (knock on wood).
Hope your problem is solved.

It seems to be. My friend hasn't had the error message since. Still, I wish I had a better grip on what caused it and what fixed it - makes me worry that it will happen again.

Sim Card Missing / Fried Sim

Okey so ive had my diamond for 3 weeks and have had this issue. The device worked fine for 2 weeks except for this problem that it keeps dropping the connection and just says "no service" but when i disable and re-enable the phone radio i get full signal. However one time the device froze and i had to soft reset. After which it said the "sim card is missing, you can make emergency calls if your service provider supports it" when the sim card was in the phone. I tried resets and cleaning the sim all to no avail. So after not being able to find anyone else with this problem i figured it must be my old 2g sim that had been causing the problems so i went and purchased a new 3g sim from my service provider (mobilezone [switzerland]) and inserted it into the device. Everything starts working again and i figure the problem is fixed. However the phone continues to drop the signal again and again over the next few days and finally kills the sim card again, and displays the same "sim missing..." error. So i have now taken it back to the retailer and they say there seems to be no issue with the device as the technichen inserts a new sim and everything works fine. The thing is that the sim cards are completely broken. They no longer work in any device!!! But it took 2 weeks the first time and 3 days the second, so the technicians agreed to test the device for a couple days, im just sure its gna work fine for that amount of time but screw up again after when i use it again. Can anyone provide any insight into this? I speculate that its perhaps an issue with my service provider since they do not have their own network but use orange (switzerland) with their custom network settings, and when configuring the device the WM6 connection wizard only has 3 options and my provider is not listed, so i use the orange config settings, which i thought may be slightly different and cause problems. Ideas?!?!?
Thanks in advance.

If it helps, I had to have a new sim to use it in my new phone (not the diamond, a nokia) because it didn't work properly, as it was a relatively old sim.
Hi did you ever get your sim problem sorted, have been experiencing same,
except my sim still work on other phones?

"No SIM"?

Tilt was previously working. Now shows "No SIM" on screen when any SIM is inserted.
Any idea what the issue might be?
I am not the current owner of the tilt, nor do I have access to it to test anything, so that is basically everything I know about it.
What is your best guess?
Thanks
is it your phone or is it a phone you got of e-bay.
If of e-bay it may be that yur IMEI is barred.

Ebay.
Well if that is that case great, because my carrier does not ban IMEIs, so it will work perfectly for me.
Is that really the message you would get if your IMEI was dissabled though? That doesn't really make sense, as it would see the SIM and you would see it say: Searching for network... Registering... and then it might say no SIM, but it says no SIM right away, so that can't really be it.
Any other ideas?
this is usualy a bad sim card..
usualy either a worn card.. or possibly an issue on the att side with your sim number
if you frequent any core att stores you might could get a free one..
I stopped bidding for it on eBay, cuz I don't feel like taking the risk.
It sold for $127.50
Sounds silly, i know, but i had the same a while ago, found the sim goes in and locks shut back to front the contact part going in last, just maybe this simple
I had a similar problem with my new Tytn II. Only 3 days old and after I took out and reinserted SIM, I got the "No SIM" message, same problem with another SIM card as well.
Just as I was ready to return the device, after a final test with my SIM card, it decided to work. I have not taken out the SIM since and this problem hasn't shown up.
There have been a couple of threads on this problem.
It would seem that the design of the SIM connector is not all that it should be.
My main SIM sometimes wouldn't connect and another couple of SIMs would not connect at all.
A piece of paper, folded if necessary, inserted between the SIM card and the metal clip to increase the contact pressure has completely fixed the problem on mine, but apparently it has not worked for everyone.

"The Sim Card Is Missing..."

Alright, new to the forums so please bare with me! Here goes:
A little while ago I started getting the "Sim Card Is Missing" error on my Kaiser. I've done many things to remedy the problem and still to no avail, the problem remains. What I'm looking for is any advice or any other ideas that someone might be able to give me on this problem. Here's a list of what I've already done.
-Replaced SIM with a brand new SIM from ATT Dealer.
-Dissassembled phone and cleaned SIM contacts as well as SIM socket connector.
-Soft reset, and soft reset, and soft reset......you get the idea.
-Wedged a piece of paper, then cardboard on top of SIM to make more pressure
-Disabled 3G network, run solo on EDGE/GPRS, as well as used outdated SIM to see if that would solve the problem.
There have been a few other "everything else's" that I've probably tried, but nothing worth mentioning.
All of these different things I've done have all solved the problem for a small amount of time (1 minute-a full day), but the problem keeps coming back. Typically after taking the SIM out and restarting my phone, the phone does work for about 15 minutes, and then ceases to live.
If anyone, anyone at all has any insight or suggestiong, please post back in this thread, your help is much appreiciated. I've already taken the phone to a repair shop and got ripped off $160, so I'm at my last rope here. Thanks all!

the sim card is missing probably the best solution
i have had this problem before on a wizard and a kaiser too what i found out on both phones one bought off ebay and the other i bought 2nd user from the local paper is that one of the phones was reported stolen (not saying that yours is) and that is what comes up when the imei has been switched off the network and the wizard i found out had an imei which had been changed. the solution i found is when i used the wizard service tool to change the imei on the phone with one on an old phone what i had to see iuf that would work, the sim card missing error disappeared and that fixed the problem so i do reckon that has something to do with your problem.
p.s. changed the imei number back to what it was as its sort of illegal to change imei`s lol

The Kaiser (at&t tilt version at least) is notorious for having a loose fitting Sim socket. If your SIM has any age to it the contacts are worn.
Put a piece of tape (or two on the back to thicken it) then reinsert it. If this fixes your problem get a new SIM from your carrier.

"No Sim Card" issue - Sim present

Hi XDA,
I recently re-encountered a problem with my N1, not sure if any body else has, is where the phone doesn't detect your SIM suddenly, giving a "No SIM Card" error, when it was working fine moments agos, after sleeping and waking the phone when i wanted to use it later. Then further reboots only result directly in a no sim error.
Before it happened before reflashing the radio fixed it, but it has suddenly come back today and i've tried everything from 03 -> 06 radios, and CM5.0.6 -> .8 Test5 and still the issue is present, where it no longer detects my SIM.
My SIM works in other phones around the house, and all the other SIMs ive borrowed to test all come up as not detected.
I am in Australia so it would be a PAIN to RMA with HTC, tho i would be in the states for 2 weeks soon so maybe if it is eligible for warranty im not sure.
Has anyone encountered these problems and what were your solutions?

[Q] Tablet shuts down when trying to access SIM card

Hi chaps, I have tried searching across the internet with no luck, here's the deal.
I bought this p1000 galaxy tab some days ago from a guy on a forum. tried it thoroughly before paying, inserted my phone SIM, got a phone call, sms, 3G internet, wifi, all working flawless. I used it for some days wi-fi only waiting for my new tablet SIM to be ready.
Monday, I receive the SIM but it still had to be activated. I just kept it in the tablet waiting for it to be OK. Zero problems, just the usual "no service" message like you would expect from a sim that's yet to activate
This morning I finally get the SIM activated, but as soon as I try sending a text or something, the tablet just shuts down. After that, no way trying to boot it up again: it reaches the Samsung logo, then bye bye. If you remove the SIM from the tray it magically comes back to life.
I already tried the usual stuff, like hard resetting and like, cleaning the SIM or something. I also tried with another carrier sim and I get the same behavior. I'm starting to believe that there is some hardware fault with the SIM reader, but I thought I'd try to get some hints from here before calling Sammy's assistance. Also the weirdest part is that it worked some days ago!
If anyone has any idea/experience to share, I'd love to hear from you mates. thanks in advance!
(oh and btw I know how to hit a thanks button)
I'll update the post with further intel, maybe it will help someone down the road.
The tablet does not like freshly activated SIMs. I know it sounds crazy but that's where we are at. We have tried like 4 different SIM cards from different operators, all work flawlessly; The SIM card of the above NOW works flawlessly as well, it just needed a couple days to settle down. I have no idea if this is a software bug, a hardware fault or some strange network settings from my carrier, but the problem seems to be solved for now. Luckily i didn't send it in for repairs!
