ahh see now you're touching on the dilemma as to whether one should simply offer a suggestion, or whether one should always assume the reader is stupid and offer not only suggestions, but hand-hold the reader through the process. (an assumption i despise, BTW, why should everything be aimed at the lowest common denominator? If someone offered me a suggestion, i'd take their answer and read around the subject, if someone else chooses not to do that and just blindly leap into the unknown, based on a single response, that's their lookout)

Yea, a coupla times.

Pretty much anything that can overheat, in fact.

I suspect that if you did the maths, you would find the moisture level of air in a freezer to be several times lower than , for example, the air in a sweaty pocket on a warm day, so the chances of condensation are pretty slim. Compared to all the other 'potential problems' this phone faces, condensation from being in the freezer is pretty low on the list.

Hello All! I hope this information can prove to be of use for someone. While I was looking for a place to upload my files for sharing I came across this offer for new users to get 25GB of cloud storage, FREE!

Now I haven't personally had much use for online storage until now, so unfortunately I cannot say how they compare to others. The only true drawback I have seen so far is that it does not support sub-folders, and thus organization is not as good as it should be. However, I did see somewhere when browsing their forums that this and other features will be available in the future (it is my understanding that they are a relatively new site). Aside from that, it is very easy to use...And you get 25GB Free!!! Have not seen that anywhere else! If nothing else, I would say it's worth checking out.

Here's how to get it if you are interested... (takes maybe a minute)

1. Go to appsumo.com/minus-for-free/

2. Enter your email address

3. Click on "No thanks, just checking things out." (right below the 2 big boxes)

4. At the bottom, click "Get the Deal"

5. Choose a password

6. Click "Continue to my Codes"

7. Copy/Paste the address for Minus

8. In box 2, (Sign Up - For Free) Choose a username and password. (email not required) Click Start Sharing!

DONE!!!

Note: The password in step 5 is for Appsumo, I am pretty sure. This is not the pw you need to use for Minus.

Note2: Yes, Appsumo WILL send you marketing emails now, but is is very easy to stop. Open their email and at very bottom click Unsubscribe! (I have an email addie devoted strictly for use with stuff like this...just in case!)

Note3: I probably shouldn't mention this, but I went through the process again to make sure I got the steps right, and I used a fake email.....aaaand, it worked! So, if you want to, you can give that a try. I really don't know how folks will feel about me mentioning this, (I am on the fence with it), so let me know what you think, and I will edit this part out if need be.

Hope this helps!

just got my phone yesterday in the morning (about 30 hrs ago)..

here is the problem..

yesterday night, my phone suddenly gave me a "No sim card found Please insert a sim card into the phone." message. Thinking it was nothing, i switched off my phone and went to bed.

This morning, when i on my phone, the same problem came back..

This problem is resolved temporary by restarting the phone.

Upon rebooting the phone, the sim card will be detected, but withing 30mins, the phone will fail to detect the sim card and display the above error message again.

I went to my provider today and they gave me a new sim card but the problem persists..

I am starting to suspect that the problem is related to the heat from the phone.

The problem occurred the first time when my phone was very hot. the problem went away when i was at the shop and the battery temperature was 25 Oc.. (air con environment)

leaving the shop and returning to my home, the battery maintained a cool 35 Oc..

the moment it hit 45+ oC, the phone failed to detect my sim card again..

has anyone have the same problem as me?

may i ask what is the general battery temperature range of your phones? and if anyone has had similar problems? :(

really need help here as a phone exchange is not possible in the short-term because the service provider is currently prioritizing sales and would not release a phone for exchange when the new unit could be a potential sales..

(PS, i was wondering if high temperature could have caused expansion of metallic internal parts, causing connections between the sim and phone to become loose or disconnected..)

EDIT: added 5th april 2012:

===================================================================================================================

possible reason for sim card problem..

just to check...

can u guys use the "turn on radio" "turn off radio" button in the *#*#4636#*#* android debug menu?

my phone has the failure to detect sim card problem and i realized that it might not actually be the heat that is causing it..

whenever the phone drops the sim card, i now hold the power button to check if the phone has switched to airplane mode... the answer is NO, the phone did not switch to airplane mode..

BUT... in the *#*#4636#*#* debug menu, the GSM radio is off and i cant switch it on using the "Turn On Radio" button...

(BIG WARNING... u might messed up your phone and made your phone become like mine...)
[HTC One X] pratik.narkar:
room temp is 30'c(no air con environment) and battery temp is 37'c while charging

and without charging it stays around 35'c

on high performance it goes up to 45'c :P.....................
[HTC One X] fi3ry_icy:
same here..

i guess my sim card slot is a bit loose, causing the sim card to loss contact with the pins in the phone..
[HTC One X] mattman83:
I had issues today with my similar not allowing me to register on network. My sim was an old mini sim cut with a proper sim cutter. I had it replaced with a proper micro sim by my provider and now all is fine.

Worth double checking if you have an older or cut sim , my provider swapped it free of charge so hopefully yours would do the same

M.
[HTC One X] pratik.narkar:
btw i just removed sim card whn phone was on it gave me " unable to detect the sim card... plz make sure sim card is inserted correctly"

then i inserted the sim card .... enabled and disabled the airplane mode and sim got detected.... so i dont think we need to restart the phone to make it detect sim card

you sure u inserted the sim correctly ?? and if u have any other micro sim which is in working condition... then try tht sim card
[HTC One X] fi3ry_icy:
mine was a micro sim from the tele provider.. i changed a new micro sim and the problem persisted..

i tried that too.. sometimes it appears, other times it dun.. mostly when the phone is hot chances of the sim card going "missing" increases...
[HTC One X] pratik.narkar:
try this......

if u can get the sim card panel of some other one x then try it on your phone and also try ur sim card panel on other the phone.... and so the same thing for sim card also....... that will narrow it down to the exact problem

show it to HTC and get it replaced ....... and if it is major issue then i think they will have to replace it!
[HTC One X] fi3ry_icy:
lol.. cant find another one x..

i already called and arranged for a 1-1 exchange.. earliest and latest (7 day exchange policy) day available is next monday.. meanwhile, i need to find a way to keep the phone from dropping the sim card.. :(
[HTC One X] xmoo:
I just went to the store to cut my sim card.

The person said if I have the old sim card, and I cut it... It mayb cause some issues...

But thank god I got the new sim card, she cut it and it is working 100% :)
[HTC One X] fi3ry_icy:
i am having this problem despite using 2 new micro sims..

looks like it is really the phone that is the problem then.. :(
[HTC One X] xmoo:
Yup.

Isn't it normal in 5/6 days you can return phone and directly get a new one?

Where I got mine I can bring it back in 14 days.
[HTC One X] fi3ry_icy:
yup..

over here we have a 7 day 1-1 exchange policy..

i arranged for it already... meanwhile, i'll find try to find a stop gap measure...
[HTC One X] fi3ry_icy:
just to check...

can u guys use the "turn on radio" "turn off radio" button in the *#*#4636#*#* android debug menu?

[HTC One X] pratik.narkar:
Just wondering ..... Did u try gsm only mode ?.... Coz my sim card does all kind of weirdness on GSM/WCDMA mode .... Losing signal,activates roaming and what not...... But it works great in gsm only mode
[HTC One X] xmoo:
HAHAHAHAHAHA

Why all the testing, just return it ;)
[HTC One X] fi3ry_icy:
yup.. i did tried it..

the phone still drops my sim card like a hot potato.. :mad:
[HTC One X] w1nter456:
dude, Go to setting, power, and then untick fast boot. Finally , reboot it.
[HTC One X] fi3ry_icy:
what does unticking fast boot does?
[HTC One X] w1nter456:
have you try that first?
[HTC One X] gn0s1s:
worked for reducing my temps. running at 38C using opera mobile after restart with it disabled instead of 48C.
[HTC One X] fi3ry_icy:
yeah, sorry about yesterday.. i just woke up now..

tried it and i can finally activate the "Turn On/Off Radio" button in *#*#4636#*#* menu..

mind if i ask how did u know about this and why does this actually happens?

2nd qns i have is, why is it that fast boot blocks this from working properly and is fast boot the reason for my unit's sim card problems?

if so, why do i not see this problem in other users?

lastly, if fast boot interferes with android core functions, why hasnt HTC fixed it since gingerbread release?

sorry if i sound too pushy, i got a new phone, and this problem appeared on the same day i got it so i am just pretty irritated about it.. once again, thanks for sorting out the *#*#4636#*#* menu problem for me so i can at least temporary fix my sim card problems until my replacement phone arrives!
[HTC One X] fi3ry_icy:
sorry, i dun really get you..

do u mean that disabling fast boot actually reduces the phone's overall operating temperature?!
[HTC One X] cookay:
I'm also getting the 'unable to detect your SIM Card' error.

It only seems to do it when it is at high temperature.

Going to ship it back to HTC...
[HTC One X] fi3ry_icy:
hope u get it sorted out soon!
[HTC One X] desireless:
Bro, I got mine from M1 shop yesterday. I also have been getting the same warning. End up my friend couldn't contact me.

Did you call M1 for 1-to-1 exchange or HTC? The last time I had problem with a SE phone and returned to the same M1 shop but the staff told me they don't do 1-to-1 exchange although it is within 7 days... which I think is rubbish
[HTC One X] fi3ry_icy:
im from singtel.. :)

got an exchange 1-1 this monday..
[HTC One X] maximus1312:
I received my HTC One X yesterday and I got the exact same problem. Most of the time it said "No SIM detected" and it overheated alot. Sometimes it did pick up the signal for a short while but mostly it didnt. Its possible that its related to the overheat issue, I read somewhere that using an HTC One without a SIM card causes it to massively overheat. Maybe it fries/damages the phone's SIM reader? or its possibly a critical hardware issue on HTC's part.

Anyways I contacted HTC and they also mentioned the disabling fastboot thing and trying again like that user mentioned. For me it still didnt work and I sent it for replacement.

---------- Post added at 10:35 PM ---------- Previous post was at 10:26 PM ----------

Did the fastboot thing, solve your problem?
[HTC One X] ayk33:
hello all guys,

one of my friend had the same issue and we went together to our provider and got 256k sim card and it works :D

try to get 256k sim card otherwise, it seems your htc one x won't work...

ps:i should have one :(
[HTC One X] fi3ry_icy:
nope..

i exchanged it for a new phone..
[HTC One X] pehkblui:
I would go there and request to see the manager. This is clearly a defect.

The worst is you have to go to HTC.

I was very lucky. I was in front of the CSO when the unit he gave me failed immediately to detect the sim. After spending quite a bit of time in the back room, he came out to tell me he would give me a new unit. Phew.

I think partly it's because I had signed the contract.
[HTC One X] maximus1312:
Does the new one work?
[HTC One X] vegetaleb:
I had the same problem with Sense 4 One S port on my Sensation, never had it before, so it's software related
[HTC One X] theliquid:
I got also got a similar sim error: when playing heavy load games the phone always says preparing sim card but I don't have to enter the pin and calling etc works properly ... So hopefully a software error?
[HTC One X] fi3ry_icy:
But that does not explain why this problem is random and does not exist in most units..
[HTC One X] desireless:
I went back to the same M1 shop on Friday (2 days after purchase). The problem is indeed heat-related (I tried putting the phone in the freezer and within a minute, the phone manage to detect SIM card again!). So while getting there, I purposely run a few apps continuously (to keep it warm) so that the problem persisted when I got to the counter and was able to show the staff.

Again, this is from the M1 staff who served me:

"Sir, usually we don't do within-7-day-1-to-1 exchange. For defective phones customers have to go back to the makers for 1-to-1 exchange. But since you are already here, we will do a goodwill exchange for you. The manager will have to sign the exchange form though.. blah blah blah"

I wonder if M1's internal policy is bigger than what is mandate?

Anyway I exchanged for a new one and it is working well!

YES, it is OBVIOUSLY a defect and if any bro here encounters it, you should bring it back for exchange like many of us already did.

PS: I just rooted it today. Superb phone!
[HTC One X] fi3ry_icy:
glad to hear u sorted the problem out..! congrats!!
[HTC One X] nimmur2000:
One x overhear

mine is 13 days old.

i think the over heat is because of sw issue and it will solve after the new fw arrives. so is it because of faulty hw?

i heard if i return to HTC within 14 days i can get 1-1 replacement. is it true?
[HTC One X] AndroidLev:
Solved!

Mine One X started not detecting the sim card. Replaced ROM, played with *#*info#*#* settings with no joy although it did briefly come back to life for about 30 minutes (although someone did say they tried to call).

I threw in another SIM that a friend had with a different carrier and it was detected fine.

My sim was an Optus Microsim from about 18 months ago.

I thought I'd give a sim replacement a go. Optus did it straight away for me, and voila...it worked immediately!

Perhaps there is an issue with older sims. I did notice that the new sim fits better in the sim carrier so perhaps there was a contact issue.

But regardless, it's all working a dream.
[HTC One X] fi3ry_icy:
yeah.. that's the case in singapore..
[HTC One X] phobos512:
Problem to detect SIM? Have it. Heat related? Definitely.

So, this morning I pulled my 1X (which I received on Thursday and setup on Friday) off the charger (I charge it with it turned off) and noticed that it was incredibly hot (nearly too much to hold, definitely too hot to have in my pocket). SIM card failed to detect (still found the Wi-Fi network in my house though).

An hour later now it still feels hot. SIM card still won't detect (I have been turning it on every so often to check but am mostly keeping it off to help it cool down).

Phone is not bootloader unlocked, is not rooted, is still running stock OS. SIM card was brand new AT&T micro-SIM, not a cut down regular size SIM.

So I called Expansys and have a message in to get a new one - waiting for returns desk to call me back. *sigh*
[HTC One X] Appelsap:
Same problem here. Was playing a simple game whilst charging, it got really hot and after about an hour starting showing the annoying 'can't find your simcard' popup every half minute or so. Problem was gone when it had cooled down the next day.

I also found out the pins in the sim-slot lose contact with the simcard when flexing the phone ever so slightly. This even happens when the phone is in my jacket-pocket, which is annoying, because then I'm unreachable. I bought a phone to be reachable really.

Mine is getting replaced, the shop will send me a new one. Although I wasn't really bothered by the plastic shell, I do hope the overall build quality of this phone is good enough so that I don't have to go through a number of replacements only to A) finally find one that actually works or B) - far worse - discover it's a dud and I have to look out for a different phone. I'm kind of hooked on that beautiful screen... :/
[HTC One X] phobos512:
Wanted to add some further information to my post from this morning. I found that the phone rapidly cooled off (as in from scorching hot to room temperature in the space of 15 minutes) and the SIM was detected properly after I forced it to restart by holding the power button down while it was booted up. This brings up the usual power-off menu and then a small black-box warning stating that the device will reboot if you continue holding the button for 2-3 seconds. Since then it has been fine.

A further item of interest is that in the hour and a half my phone was acting up, it used up 43% of battery capacity. And the battery status indicated that it had been operating on battery from the first boot even though I had shut it off for over 30 minutes of that time (indicating it had not shut off properly).
[HTC One X] jerry2:
I had a simmilar but different issue. My phone since I got it said Preparing sim card and connected to my carrier and after 10 seconds dropped off :-( This happened every time except one I stayed on the carrier for 2 hours and after the reboot it was gone. It is not hot.

I have sent it back to Expansys and now they say it works in France. And none of the other customers in Slovenia that arre on the same carrier got it to work properly. Carrier says it is HTC problem not able to detect their standard micro SIM (I have a new one, not cut out), but the wierd thing is it is supposed (I can not verify) on a competition carrier. So what is it now... Nobody seems to know, but I have yet to find another phone who doesn't work with one carrier in my country :(
[HTC One X] noisy_lightning:
I have similar issues but my problem is NOT heat related.

See here for the full description of my issue.

One final question, for those who have the problem with the sim card when you shake your phone do you get a rattle coming from the area of the sim tray, both with the sim tray in and out? Mine has something loose inside by the sound of it so i am wondering if it is linked.
[HTC One X] shrubz:
I too have the same issue regarding "Preparing Sim" messages, seems to occur randomly, I'm on Three UK network and the phone is unmodified. I too have a slight rattle in sim tray area when shaken. Not sure whether this is a hardware or software issue.

Have tried a new sim card and I'm still getting the same problems.

HTC weren't much help, factory reset then send it back!!
[HTC One X] noisy_lightning:
I swapped mine and the new one is perfect. I would say from my experience it was a HW fault without doubt!
[HTC One X] fi3ry_icy:
i think that rattling sound is present in all htc one x units..

i have it on my faulty phone and the replacement phone which is currently working fine..
[HTC One X] SleekY:
defintely a sim tray issue.

Had my sim replaced today - was previously using an old cut down to micro sim.

Noticed that H/3G would constantly disappear and would randomly come back, so i thought i'd better get a proper micro sim.

Removed the old sim and inserted the new one - No Sim detected.

Push down harder on the tray with a bit of sticky tape to thicken the sim it started to work.

begin to use it and be slightly rougher with it e.g. put in pocket, press around the lock button etc it loses signal again :(
[HTC One X] fi3ry_icy:
nope.. even with the tape it would only work temporary..

AND u will have a hard time trying to eject the tray out..

i tried the tape method.. ended up trying to pull out the tray without damaging the tray plug or else HTC might not want it back..
[HTC One X] SleekY:
yeah that was my concern as well.. have tried calling Expansys but i got no answer - only got 30 days with them and nearing it!

will have to e-mail them just to have some proof that i was in contact within 30 days.
[HTC One X] Damir.g:
Some say its a heat issue but at what Temp?

I had trouble getting my hox to accept the sim and its a standard micro-sim.

no cutting ore nothing.

I had to do a factory reset with the sim inside and it worked fine,

then i turned on my wifi... Gone no more sim. temp was normal 38-40.

and the battery life on full 8 hours. without sim, with the sim even Less.

tried it 2 times with 60% and 75% battery and woke up tot an empty and dead phone.. 2e time i turned off 3g wifi.

The sim thing is stupid its gotta be software, had it working fine in my pocket for 4 hours.

the battery issue don't know the system is drunk and takes its fill.. so again i think Software.

Tomorrow im calling to get a new one hope that one does work..

cause Samsung SUCKS!!:eek:
[HTC One X] Z51:
I was having this issue with my old and worn T-Mobile sim. I got a new sim and the problem went away. Guys try a new sim. :) worked for me atleast
[HTC One X] ash_haddadin:
Restart

I had the same problem after about 2 months since I got the one x. It couldn't detect the sim. I just held the power button and clicked on restart. Clicked on yes or ok (can't remember). After it restarted, the sim got detected. Before this I tried turning the phone off and on but it didn't work. I don't exactly know what causes it but if this works for you it could be a software issue since restarting the seemed to work. I'll tell you guys if it happens again. Tell me if it worked for you guys. Sorry if someone posted this already. Just got a bit excited.
[Nokia Lumia 900] exceta:
Since their are several reviews out and the phone itself is coming out in a few days, I was wondering if we will know soon if the Lumia 900 will run on T Mobile.

Specifically I am interested in the new $30/100min plan with unlimited text/web. What is the hardware requirement the phone has to have to be able to run on T Mobile's 4G network? And if the 900 never were to come out officially for T Mobile, would and unlocked or international version of the phone work?

I understand that a lot of this is still assumptions but thanks for any input.
[Nokia Lumia 900] FiyaFleye:
If you unlock it, voice & edge features would work. But, 3G/4G would not.

Sent from my HD7 using Board Express
[Nokia Lumia 900] geoken:
what are you basing this on? Has someone verified this?

At present it seems pretty ambiguous. On the one hand Nokia doesn't mention it in their specs, on the other hand the FCC filing lists 1700 as a UMTS band (as well as an LTE band). Also, other AT&T phones (skyrocket) using the same Qualcomm 9200 work on T-Mobile.

I don't think anyone could give a definite answer until its been tested.
[Nokia Lumia 900] cx1:
I think we will find out in a week or so. The FCC filing links back to the Finnish documents that appear to have testing for those bands. It's unclear to me if there are multiple variants tested in the documents.
