Problems with Unlocked Kaiser on AT&T

I've had my unlocked HTC Kaiser for 2 months now on the AT&T Network no problems. On Thanksgiving Day, my phone decided not to turn on after I left the phone to charge overnight. I figured it did not get a good charge so I tried recharging it. It was flashing red lights near the the top of the phone. So I go into AT&T on Friday to see if its the battery or the european charger that may be at fault. I played around a few combinations in the store and it suddenly/magically turned on. (I decided to buy the charger and extra battery anyways). The employee decides that for some reason or another, the phone needs a SIM Card. Well here is where everything went downhill.
After the new SIM card, I was unable to make or receive any calls, and no access to my data plan. Sometimes, I would have full signal bars but still was unable to make/receive phone calls. I've been able to make calls on very rare occasions; especially in this room in our school. What to give? So I went into another AT&T store and noticed that they had the incorrect IMEI number down in their system,. I asked for them to fix it but they said they couldn't change it for some reason and that the IMEI wouldn't be causing the problems I'm experiencing. So I finally called Customer Service Support on the phone and supposedly they were able to change it to the correct IMEI #. But still the same issues. I've done soft, hard, master resets, take out the battery + SIM card, you name it and still the same problem! When I took the SIM Card out of my phone and put it in a Blackberry, it did work! But when I took the Blackberry SIM Card into my phone, it did not. The support team told me that indicates that it is my phone; but I clearly told them that it could also be due to the fact that the towers just aren't recognizing my device no longer.
So I spoke to HTC about this and they said its the SIM card and they wanted me to go in and get another SIM card. So I went into AT&T today and got a new SIM card but same problem. Again, same issue. So I called AT&T Customer Support today and asked them to bump me up to Level II or III support. She says she cannot do that because my phone is unlocked (from HTC) and no support for that. I gave her the rundown on how my phone was working for 2 months until they put in the new SIM card and my cell phone activity clearly show that. Then she goes on to mention that other technical service reps that have helped me in the past few days clearly have pointed the culprit to be my device and not AT&T as they have exhausted all tests. And I told her, it's like taking a brand new car to a mechanic and then get the car back not running. If you ask the mechanic what did you do to my car, he's not going to admit to anything. She says that my device isn't being recognized by the towers. So then I brought up the point of "So is it my tower or is it really my phone?". I told her it's no problem getting a new phone but if I get a new phone, will it be unrecognized by the towers again. She said yes because it is unlocked. I said what about the thousands of other people who use unlocked Kaisers or any phone for that matter as they seem to have NO problems. They basically want you to buy the phone directly from them.
In all, I've spent nearly 10 hours on trying to get this thing to rework and be able to place/receive phone calls. Whether this is due to the events which ensued after the red light indicator on Thanksgiving Day OR the fact that AT&T switched my SIM Card and caused my device to be undetected by towers (whether it was due to the fact they put in the wrong IMEI in the first place or any adjustment they made to my account) remains to be determined.
The only options that remain is: 1) Go to TMobile and try out their SIM card on my phone and see if it works. I highly doubt they too will let me do that as they consider phone unlocked and don't want to help 2) Get a new phone through HTC and hope it'll work on AT&T again.
Any ideas or support??? heheh. your help is truly appreciated

I feel you pain Brother.......
I don't have a clue how IMEI and towers can just not register your device...though....but anyhow, did you check if you have the Phone in the Dialing screen-Menu-Options, then the tab BAND on the bottom and both of them selected as AUTO? if not, then try changing bands.......
If you know that then, I'm thinking only of AT&T could have blacklisted you or some sort.......but that is highly unlikely......
I had some problem like that when i'm out of the country using Foreign Chips, and it seems the Kaiser needs a bit of time to adjust to new sims, and that can take minutes, hours...or even days......who knows what is happening as the phone is "learning"....... hope this helped you a bit....

I've been using my Kaiser for several months now and I did not register my IMEI, I just popped the sim out of my 8525 and took off running. It sounds to me like your phone has failed in some way, especially if your new sim works fine in another phone. The question now really is, where can you get a Kaiser fixed in the US? I spoke with HTC on another subject and I get the feeling that it may be difficult. I got mine from a shop in Canada, guess I'd have to go thru them.
In any case, good luck, it will be interesting to see what it turns out to be.

I second RemE -- like him, I bought a Tytn II & plugged in the SIM from an older phone (in my case a Qtek 9100 not bought through AT&T/Cingular), and have had no problems.

i had a similar problem with my 8525. I bought a Tilt to replace it, and about a week later I gave the 8525 to my son to use. neither his SIM card or mine would work in the 8525, but they worked in other phones. I brought the phone to the AT&T store and the guy there did something on his computer, then the phone was able to work. I'm not saying that AT&T blacklisted it, because I don't really know. But it took a change by the AT&T rep at the store to get the phone working again.

I have been using Kaiser with ATT for three months now with no problem. I just used the sim card from my Blackberry and so far, no problems.

Missing sim card?

Okey, here is a stange problem!
I purchased a used Tytn II today, and everything seems to work fine! BUT there is a BIG BUT, every time I restart my device it says that the sim card is missing even tough it is in fact in the device, then I have to take the card out reset the device shut it off again and insert the sim card!
Sometime it works and sometimes I have to repeat that procedure several times before it realises that there is a sim card!
Is someone else having this problem, and if yes how do you go around fixing this?
Or is my device simply broke?
Thanks in advance!

I posted this a couple of months ago - works for me
"Happened to me when I got a T-Mobile PAYG SIM last week to trial for data coverage.
Popped SIM in and worked well.
I then tried a Vodafone Sim and that was ok.
When I put the T-Mobile SIM back in - I got the message "no SIM found"
Tried Orange and Vodafone and they both gave the same message !
I was not convinced the SIM'S were making good contact - there seemed too much movement under the flimsy metal crossbar.
The solution to get the T-Mobile and other SIM's working was to insert a small piece of paper on top the SIM as you slide it under the metal crossbar.
This puts a little bit of extra padding on top of the SIM to help make decent contact.
I suppose the paper could be put on top of the crossbar instead to achieve the same effect but have not tried this.

Also make sure the sim is clean - use a pencil eraser is one suggestion.

So far so good!

Okey, I tried to put some paper between and so far it works!
The strange thing is that I did not even try to replace the card, I just rebooted the device and the sim card was missing!
Cant figure that out!

Hi there,
I just wanted to stop in and say thank you! I have been beating my head against the wall for the past two weeks over why my Tilt kept losing its network connections in perfect conditions and constantly telling me the SIM card was missing. Reseating it only worked once in a great while, but slipping a piece of paper in there seems to have done the trick nicely. I did notice that the contacts on the Tilt dig grooves into the SIM card contacts - do you think perhaps this is the problem or is this common among cell phones?

Thanks Bigdish, worked for me too.

thanks a lot for the information, putting a paper on the SIM resolved the issue in my tytn II, I was so nervous when I saw sim not found in my phone and tried to do reset several times and also repeated the ROM upgrade several times and finally a piece of paper served the purpose thanks....

The Sim Card Is Missing

this is not a repeated topic
i searched all the web for solution but i couldn't find any
my At&t tilt is unlocked it works perfectly for short time ever few resets
else, it give the message "the sim card is missing" you can srtill make emergency calls if your provider supports it
i tried every thing, unlocker, hard spl, all the tools herebut nothing worked
can any body help?

Any chance the SIM is loose in its mounting?
It looks to me like there is a bit is wiggle space in the SIM slot.

did you try another SIM card?

One of my kaisers uses an old sim where a layer of laminate had been peeling away. This meant that when I inserted the sim, the loose laminate folded back on itself and acted as an insulator between the brass phone and sim contacts. So I removed the offending laminate but still had the occasional "no sim installed". The problem was that the sim was now a little thinner. I applied pressure to the centre of the metal belt that holds the sim in place ensuring that the contacts were "always together" and have not had any problem since.
I hope this simple solution works for you.

ANother thing you can try is rubbing the gold portion of the SIM card on your jeans or clean it off with a pencil eraser. I had that problem, and it stemmed from a little corrosion or crud building up on the face of the SIM card, and by rubbing it on my jeans it cleaned the corrosion off and the sim was able to make good contact with the points in the card slot.

Sometimes sim cards go bad. I've had about half a dozen go bad out of about 40 devices that I have supported over the last couple of years. AT&T acts like it's a common occurence and no big deal. I just take the device to one of their storefronts and they replace it immediately.

is there any way to restore every thing it's initial conditions?
i'm getting frustrated here

Did you try unplugging the battery, put the sim card and then reinsert the battery and start?

hey just wanted to say thanks. i just added a piece of paper between the card and the metal part and it worked. just wanted to say thanks.

I had the very same problem today after putting a brand new sim in the phone.
Found that I had put the damn sim in the wrong way round. Oops.

I had the exact same problem and in my case, putting a piece of paper in did not help at all. I had to get a brand new sim card.

i had a similar problem. it couldn't read my sim card, but read my gf's tmobile sim card and her phone read my sim card fine. then i next day i took it to an ATT shop, asked for a new sim card and it worked perfectly fine now. even the guy from the shop couldn't tell me what is the problem, he said, it happens every now and then.

"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!
Dig Life!

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 problem.

Hello to all,
before u start saying to search the forum, i did. But havent find solution for my problem so i opened a new thread.
So the problem is that my tytn register some sim cards but some dont, its like a random thing. My old sim card and new one works, now i tried with new sim card but from a nother network, and it says no sim, i try with my old sim from the same network and it works. I tested with about 10 random sim cards and 6 out of 10 works, no matter how old they are and from what network they are. I flashed my phone, tried new roms, cleaned sim card slot, but nothing worked.
If u can help me, i will be verry grateful
P.S: Sorry for my bad english

out of the 10 sims, 6 work...correct? lets call the sims that work numbers "1 through 6" and lets call the sims that don't work numbers "7 through 10".
i would say it is a hardware problem IF AND ONLY IF even one of "1 through 6" STOP working or if even one of "7 through 10" START working.
in other words, it is NOT a hardware problem if "1 through 6" work consistently and "7 through 10" fail consistently.
if you determine that it is a hardware problem, then try inserting a piece of paper behind the sim for an extra tight connection or search for bad/loose "main flex cable" and/or "sim assembly".
if you determine that it is not a hardware problem, search about possible known incompatibilities of the kaiser with certain networks' sim cards.

Thanks for advice...i fixed the problem by bending the metal that holds sim card.
But i still dont get it how that fixed things cause sim cards one that worked they worked every time and othet way around with non working sim cards...but ok... now they all work...

nice to hear your problem is solved!
i believe the sim cards that didn't work were probably just "thinner" than the ones that worked. so bending the metal pushes the thin sim cards tighter against the connectors. inserting a piece of paper behind the sim card has the same effect, and it is one of the first suggestions you will read about in most threads about sim card problems.
anyway, congratulations, and its nice to see that you updated your thread with information that helps "close" the issue...perhaps you can change the title of this thread to indicate that the issue was "SOLVED" so that future readers can benefit from it.
