So it finally got here. I spent four hours loading apps and setting configuration. I turned it off to clear it out and when it rebooted it said "no SIM card, emergency calls only." It was the card out of my G2 so I thought there was something wrong with the G2X. When I put the card back in the G2 I got the same thing - "no SIM card." I've been through a lot of SIM cards over the years and never had one crap out so I'm assuming the phone did something to it. I'm on the phone with T-Mobile now trying to get the new SIM card that came in the G2X box provisioned.
It also spontaneously reset my Bluetooth settings back to stock wiping out all the paired devices and the name I gave it.
There's other strangeness to report but I'm too tired. Tomorrow.
I would like to know how that'd be possible. .. frying a sim card?!? I mean could it short it out? LOL everyone is posting a lot of problems. Only thing I'm pissed about is this bleeding on black/dark screens.
Other than that this thing smokes any phone I've had!

Bluetooth issue happened to me once so far.
It happens. More than likely, it is just coincidence.
I have had a SIM last 7 years, and I've had one last only a couple months.
It's nothing to do with the phone, just get a new SIM and move on.
Hey guys.
I have noticed large variations in the signal that I have. E.g., somewhere that I normally have 2 bars, from time to time it may display 5 bars or no bars at all, but I can still make a call.
The real problem occurs after long period on standby, after which it seems not to recognize my sim. It has happened 3 times in a 4 day period. The problem is solved if I restart the device or disable-enable the plane mode, but this is not a real solution, since meanwhile I've missed a few calls...
I have no weird apps installed, and I am experiencing the signal variation since day 1, without any apps installed.
Any ideas? Contact the retailer maybe? I bought it from expansys on April 11th, what is their DOA period?
Contact HTC maybe? Or get a new sim?
Your help is highly appreciated!
I suffer signal variations too, I can go from 5 bard to 2 bars and back all in the same location.. Ive never had 0 bars, or had a call drop. But its something that bothers me
What you should do is
Check with your provider for any faults in your area
Request a new sim
Contact your retailer
contact HTC
All in that order.
I also have this problem. I have tried a new simcard but still problem. I hope HTC will solve this, because it seems to be a software problem.

Thanks for the quick answer.
I do not mind the signal variation, since I can make calls even with 0 bars (!), of course I don't know if this affects the battery life...
My real problem is, not recognizing the sim... I also forgot to mention that the very first time I inserted my sim into the phone, it didn't recognized it either.
I 'll get a new sim from my provider, hoping it's not the phone's fault.
In the meantime, I 'll let the retailer know about the situation and ask about the DOA period, in case that doesn't work.

You mean, just the signal variation, or the sim not recognized after standby?
you should rly try to get new sim card, could be sim problem.
For signal variation, it probably drains battery life. If signal is weak, or it drops from 1 bar to 0, then back to 1 (had this situation at my work) - battery gets drained RLY fast.
But that was in case when I rly didnt have or had rly weak signal. Dont know with this, but I guess if phone trys to "recover" signal, it will consume much more battery

The SIM problem is a separate issue, which you should hopefully get fixed.
Now regarding the signal strength bars. I have used a lot of expensive RF test equipment. Most of it more expensive than your car. Or house.
None of them measured signal level in "bars", usually it was dBm (mW in 50Ohm). Unless you know what those bars correspond to in real power levels, then it's rather hard to say if the variation of a few bars is something to worry about.
Digital comms systems tend to go from "working great" to "no signal" within the span of 6dB. And that's a very small range when one looks at the variation of signal level in a typical urban environment, even if the phone is static (position-wise).
It's been some days now and I don't have any more sim issues, so all good.
Maybe it had sth to do with where the sim was touching the phone... (I tried cleaning the sim and reinserting it a couple of times)
But the signal variations continue... I reached HTC and they said to try GSM only mode, and also safe mode, but same behavior there. - now rechecking and unsure about results, gosh it seems complete random.
aza314, I understand what you 're saying, but what about this... the signal variations are so annoying, that rarely I might unlock my phone to get a temp "no service - emergency calls only" message (normally I have signal again in 1 minute or so), in the same spot I was making calls normally some minutes ago (or later).
Guys, I need your input here... if you have never experienced such a behavior on your phone, if it's not a known bug, I need to know, in order to report it DOA.
edit: on the other hand, maybe it's related to this issue, so hoping to get fixed in the first update...
Iv had the AT&T One X since the 4th and so far I love it! I haven't had any wifi issues or bootloops or anything, the only problem I'm having is the phone will randomly lose signal completely (0 bars, little x next to the signal) and wont get it back unless I put it into airplane mode and turn it back off, or reboot the phone. In the 6 days Iv had it it's lost signal 3 times, once on the road where I normally get at least 3-4 bars, and the other 2 happened at some point over night while I was asleep. Has anyone else been having this problem? Also do you think it's a software/radio problem that can be fixed in a update, or would it be hardware in which case I should take it to the store and exchange for a new one.
I've had this problem myself. Had the phone for 19 days now and I think it's happened to me 3 or 4 times.
I can guarantee it's fixable with a software update, even if the problem is hardware-related. At the very least, the software could detect the lack of signal and automatically cycle in and out of airplane mode to fix the problem without user interaction. But I'm sure whatever fix we get will be much more reliable than that.
WHEN we get the fix is another question...
Thanks for the reply. I figured it might be a software issue since you can cycle airplane mode and get it back and I don't really want to take it down to the AT&T store for an exchange in fear I wined up not able to set up gvoice or start getting wifi issues and the like lol. so far the signal drops are far and few in between making it an annoying issue rather than a critical one, and I read we've got root now so even if HTC/AT&T twiddle their thumbs and pretend nothings wrong I'm sure the community can save the day lol
I would swap it out Azure. My first HOX did exactly this, and I saw it reported elsewhere on a number of other devices. To me that says it's most likely a bad radio flash on some handsets. I suppose you could try and flash the RUU that was posted, as it most likely includes the radio as well.
I got tired of all my calls going directly to VM without ringing. And not being able to send out texts. My replacement works much better (or rather, how it should've from the beginning).

Was this problem intermittent?
My phone has been doing this randomly, except it never went to voicemails, just hung up after like 30 seconds.
Wondering if I should switch it out also.
Had this problem for a day. Took my phone to the at&t store and they changed out the sim card and I haven't had a problem since.

I never thought about the sim card being a possible problem...might run up to the store when I get the chance and swap my sim out and see if that fixes it, if not I'll just swap the device out and hope all's well
The CSR actually swapped a new micro sim first, since the one provided via online sales was an older one (most likely from the iphone 4/4s batch). It didn't seem to fix the problem though.
And yeah, the problem was very intermittent. One second it would be working fine, and the next it would show the "x". Sometimes the bars would come back immediately, other times it wouldn't until I rebooted or cycled airplane mode. Luckily it happened while I was at the store; it's much easier to convince a sales rep to swap a phone when they can witness the issue(s).
Yeah it's only happened to me twice since I got it on the 4th... it'll be very hard for me to convince them that there's an issue haha... maybe I'll head down there if it happens at a time when I'm not in class or something. I'm sure if I mention returning it/their policy I'll get a swap.

next time my phone drops signal I'll take it into the store and see about a sim swap in hopes that'll fix the issue if not then I'll reluctantly swap the unit out (I've grown rather attached to this one xD)
**EDIT**
strange...woke up today and my phone completely lost signal again, normally there's a few days between each event but this is the first time it's happened twice in a row =\
So it happened again, I'm going to go get it switched... but it says on the Mobile network section of settings, "Disconnected because service is unavailable."
There is clearly almost full signal strength, and I have never been without service where I live.
I was expereincing constant network drops all of yesterday due to an outage. However, it's back to normal for me today. So it may be possible there's an outage near you as well.
I think it is more AT&T than your phone. I was in down town buffalo at a swim meet with 5 bars of hspa+ on my blackberry bold that has a great radio. I had data but it was slow dial up slow. There were maybe 100-200 people at the meet and it was at a community college. The only other time I had this was when I was in a car that was driving by the buffalo bills stadium. Voice worked but I had no data. I guess too many people using their cell phones.
Definitely not AT&T, my SE Xperia x10 worked perfectly fine, never had any trouble with signals.
I also encounter the intermittent signal drops on my 4 days old AT&T one x.
It seems to me that the One x doesn't hold signal as good as the iphone, my 4 and 4s usually get around 2 bars in some really remote locations of the building I work. But the One X just drops signal completely. I'll see if I can do a sim swap like some others suggested.
I'm starting to think it could be an issue with lte phones because the same thing was happening to me on my galaxy note with 2 different sim cards and 2 different devices and now it's happening on my hox

it has happened to me 3 times in 5 days. All 3 times I was either:
1. in a poor reception area and it came back on its own, i did not have to use airplane mode.
2. was using BT streaming in car and using car charger, once car charger was unplugged, signal came back.
One X has issues
Definitively problems with the phone.
I have three.
They just drop signal completely. One will work, the other will not. Only way the signal will come back is if you turn the phone on and off again. I love everything about this phone....except it isn't a very good phone.
Also, typically when I turn the phone back on, that is when I get my text messages. Nice.
Yeah I figured out it happens when I lose signal (a couple buildings on my schools campus don't get reception), and then the signal won't come back until I reboot or airplane mode.. this is after a sim swap.
Oh and do I need the box my phone came in to swap it?

I have had this issue as well being on the Rogers (Canada) network. I started a thread as well and my theory is there may be a hardware issue reading the SIM cards.
Every now and then I get a "preparing SIM" message pop up on my screen. Also, I lost signal once and in frustration I slapped the phone into my palm VOILA! signal came back full.
This is the second One-X I've gotten from Rogers so there may be a design flaw somewhere. The problem is this behavior only pops up intermittently and cannot be recreated at will. This makes troubleshooting very difficult and practically unprovable in the eyes of providers.
Hopefully there are more reports of this problem and the carriers push back on HTC to resolve the problem.
Hello!
A while back I dropped my Samsung A71 in water and when I started it after drying it everything appeared to be fine. But after 2 weeks or so a problem with the SIM card appeared. The card gets recognized, and I need to enter my PIN, however, I do not have any mobile data, which obviously is a pretty severe issue since I cannot make or receive calls and texts.
The odd thing is that after 20-50 restarts, it suddenly starts working normally again. This makes me wonder, is this a hardware or software related issue and would it help to install a custom ROM. My phone is rooted since before so maybe there are some mods that could be handy to search for a solution.
I'm very grateful for any help!
Few months ago, I dropped my Galaxy S7 in the water, too. It had some very weird restarts so I teared it down, cleaned it up, then tied it up.
There were two cables I did not tie, thought it wasn't necessary, so when the phone booted, it was just fine, except the network, it was showing "Emergency Calls Only", sometimes shows "No SIM Card".
At first, I thought it was EFS issue, so I tried a lot of recovery methods, none did work, however LTE only mode could receive signal sometimes.
It took me a month to figure out that it was the cables I did not implement.
It's definitely a hardware problem, and it seems like it's just water stuck somewhere between these cables, or near the SIM tray.

Thank you so much for the suggestion. I'll see what I can do and hope for the best!
I purchased a used US version Rog Phone 5 recently through an online seller. When receiving the phone, I gave it a good once over and powered it on and tested wifi and such and everything seemed to be in good working order. I then rooted the phone and set most of stuff up. After inserting my sim card, I noticed the cell reception was not that great. I suffered through for a couple of days but was missing calls and texts like crazy. I was constantly dropping reception entirely in areas where I have very good signal with other phones. The phone is essentially useless now. I tried several factory resets, flashed back to the non-rooted boot image, and then flashed to an older firmware with no improvements to signal. I can't imagine the reception issue is in any way related to the rooting process, but I'm throwing this out there just in case anyone has seen anything similar in the past.
A few things to note:
I am on AT&T
The APN is definitively configured correctly
I could have returned the phone to the online seller for a refund prior to unlocking the bootloader, but did not insert a sim before rooting, so I have no idea whether the issue was present from purchase or not. Lesson learned, I suppose... do a more thoroughly inspection before doing anything that will void a warranty or refund agreement.
I have tried the same sim in two other phones with no issues.
Everything else about the phone seems to work perfectly, only poor reception.
I had the phone up to approximately 30 miles from my house with no change, so it isn't limited to a specific tower.
Does anyone have any ideas? If I don't come up with anything I will be posting it on ebay as "not working - for parts only" so I will try about anything at this point.
Sim recognition issue
Owned the phone for about a month now. Phone was working perfectly fine for the majority of this time. I use 2 different sims and they were both working smoothly until recently. A few days ago, I woke up and the phone wouldn't recognize the Sim...

Sounds like they pawned the issue off on you, but it should still be under warranty to have it repaired. When you contact Asus, don't mention unlocking the bootloader. Stick to the hardware concerns.
I have looked over both of those threads, but it seems to be a different issue. My sim is recognized fine, its just the signal strength that appears to be extremely low. Even when the phone has no service at all, it still recognizes the AT&T sim is present.

Yes, it is not the same issue, but it appears to be a similar issue. The important detail being that both required a motherboard replacement.
