Ok, I'm going to give you guys the whole background story just to cover all the bases.
I've had a Nexus S for about 6 months, never had a hitch. Rooted it, etc etc all fine and dandy.
About two weeks ago, I updated it to CM 7.1 RC1. So far so good.
I've always had the same Vodafone SIM card, which has accompanied me through a couple of phones. Last week, I went to London and bought a UK pay as you go card, to use data without roaming. Perfect. No problems whatsoever.
So, to make it clear, I never had problems with my original (portuguese) SIM card, nor with the british one I had just bought.
However, it was upon my return that I realized I had forgotten my SIM card at my friend's house. I quickly stopped by the Vodafone store at the airport, where they promptly gave me a new SIM, ready to use within a couple of hours.
Since then, my phone after a short period of being on, spontaneously fails to detect the SIM card/no longer recognizes it. I've tried scanning for networks in the settings, but it won't let me register again. It takes a reboot to get it working. Thing is after a couple of minutes or hours, it happens again.
I have since exchanged the new SIM card with a newer one , also from Vodafone, albeit a different store. Yet, the problem persists.
I didn't alter any settings between Portugal-UK-Portugal, so everything should be exactly the same. Does anyone know how to solve this or why this happens?
Faulty phone?
Faulty radio?
Faulty SIM cards?
ROM bug?
Any help is appreciated.
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.
Hey guys, so I recently got a replacement Lumia 710 from the Nokia repair center, and it works fine but I noticed that it will reboot completely randomly around 2-3 times a day. From what I can tell, there is no specific trigger that causes this. It's almost always been idle (sitting on my desk/ in my pocket) except for a couple times. This problem occurs with stock and custom ROMs. Also when the phone comes back, it seems like the battery percent jumps down ~4-6%
The only thing I can think might cause this is a new SIM card. Before I sent my phone in for repair, I had a regular SIM that I cut into a microSIM. Almost immediately after getting my replacement phone, I activated a real microSIM I got from AT&T. This weekend I plan on trying to get a replacement SIM card from AT&T again to see if that fixes it, but I wanted to know if anyone else ran into a similar problem.
The thing that really confuses me is how random the bug is. It happens whether the phone is in use or not, at random times of the day, on a couple different ROMs (including stock), and only 2-3 times a day. I'm considering sending it back for repair, but I'd like to hear from you guys before I go 2 weeks without a phone.
Phone Info:
T-Mobile US RM-809 Lumia 710 (white)
Phone OS: Currently running WP7.8 (RainbowMod ROM) but the problem is ROM-independent.
Hi,
exactly the same problem but only since the 7.8 update. Before the update my wife never had any random reboot.
The phone reboots randomly 2-3 times a day.
Maybe it's a coincidence.
hey!
I have a problem with my One Mini. I have constant signal dropouts. Phone calls stop after a second, also losing data-connection all the time and always seeing the message "Preparing SIM-card".
It feels like my phone having problems with some mobile-cells. Usually I have to try to call someone 3-4 times, and after 3-4 attempts I can talk normally without getting interrupted after 1-2sec - like my phone found the correct cell or something like this.
I tried
- my second (O2) sim-card
- put some tape on top of the sim-card (solved this problem for people with different phones)
- put some signal-tweaks in my build.prop
- changed network mode (WCDMA/GSM/LTE...)
but nothing helped.
I am on O2-Germany for many years and never had those problems, my One S was working fine (before it got bricked )
Had the same problem last month in France...
anyone else having this problem? could this be kernel-related? I'm using JMZ`s kernel. But I guess this is more a radio-problem, or?

I haven't had this issues, in fact, I went camping last weekend and most of the time I was able to get 1 bar when everyone else didn't have service at all. I'm using the AT&T variant on AT&T with the WWE DeOdexed Stock ROM and Jmz's Kernel 09-04-13. I attached a picture of my kernel, baseband, build, ect. I'd suggest making a backup and restoring your phone to stock to see if it's a software issue.
TLR - Is it more likely my 4g sim card has died out of the blue or the radio in my older Droid Bionic has fried?
-Using a droid bionic that is probably 3 years old, duel booted with the newest kit-kat. Problem occurs on stock as well.
-So for the last few months my phone has been dropping all service(wi-fi & data/cell) then coming back on a few minutes later.
-The other day 4g/cell service dropped completely. The wi-fi still works but seems to be iffy. I have to airplane mode on and off a few times to get it to come back.
-I'm looking to buy an HTC One m7 off craigslist (I still have unlimited data) and I don't want to buy a new phone if a new SIM card will solve the problem. In turn I don't want to buy a new SIM card and have the phone be the problem.
-I've gone to two verizon stores and one said SIM cards die often, the other said it was the phone.
Does anyone have any thoughts on this? I'm poor and it could save me a lot of money.
Thanks in advance
