[Q] htc desire won't connect to a network

Hi,
Two days back my htc desire suddenly lost connection to the mobile network. I now get a small cross on top of the signal bars and "no service" written on the notification bar. Sometimes this changes to "sos".
The wifi is working fine. t
The only problem is voice and data over the mobile network.
I tried a lot of things:
reboot
flashed a new radio
complete wipe/ factory reset
flashed a new rom
But to no avail.
A strange thing did occur though, at a mall, my phone suddenly started working for a few minutes and then went back to the same state as before. This same thing happened last night too.
I am unable to understand this and request all of you to help.
current status:
Phone: htc desire amoled
s-on
bb: 32.56.00.32U_5.17.05.23
miui 17.15

Ring your provider.

S.O.S. Problem

So I assume the problem would be the ROM
Any solution to this? Patches or something?
I would love to continue on using MIUI
Thanks all
Regarding the above problem.. had the same thing... what i did is this..
on dial pad use *#*#4636#*#*
then goto phone information (first one)
scroll down you'll see "set preferred network type"
mine was selected "WCDMA" I changed that to "GSM Only"
Since then no problem of S.O.S has come to me
I am sending it here because I am unable to post in the forum... something to do with minimum of 10 Post.. Hope this helps

Guys thanks for your replies.
I have already done the *#*#4636#*#* bit and it hasn't helped.
Regarding the rom, I was originally on cyanogenmod 7 when this problem started. I re-flashed CM7. Didn't help. Then i flashed miui. the problem remains.
Although I would like to add that over the past two days, at two different locations, I have been able to make one call and recieve one. How this happens, I don't know.
Still trying to figure it out but I just read elsewhere on this forum an exactly similar problem being faced by a few people during the last few days.... so keeping my fingers crossed.
Ah! and one more thing, I have tried sim cards of almost all operators and none work in this phone.

Same problem here aswell,
me too tried every thing,
but non of them helpfull..
Still searching for help

This may seem like a dumb question, but the people experiencing this problem, are you in the same country/region?

A little update in my situation:
I visited another city for an hour yesterday and the phone latched onto vodafone in seconds and worked like a charm but as soon as i got back to base, it was back to its dead state.
This is a really confusing situation because, one moment it seems like its a hardware problem (since none of the operator's sims tend to work in it while in delhi) and then sometimes it seems to be a network problem (as it seems to work just fine in some areas)
Guys, please.... please help. This is so frustrating.

guys i'm still waiting for a reply.... doesn't anyone here have a solution to my problem?

Install cm7, then full wipe and then install freshly your new rom.
I did that way and after that was network connection back.
Sry my bad english!

Hey this worked but only partially. Now the phone does latch on to network at most places except two: my workplace and home.
And in some places it shows full signal strength but calling is not possible.

[Q] Text messages and calls not being received

I've been having a problem with receiving texts sometimes and I recently noticed that it happens with call apparently. The issue is that I'm texting people back and forth and then all of a sudden I wont receive messages for a long time (couple hours). At some point, someone's text message will push through all of the other ones all at the same time. Sometimes when I assume i'm having this issue, I will send a text to myself and it will push the other ones through as well. Recently though I was made aware that during this "outage", I also was not able to receive phone calls at all. The signal is strong at all times (3-4 bars). Also happens when I'm home all day and not changing locations when it will suddenly stop getting texts and calls. Does anyone know how to fix this issue? I restarted the phone and changed cell towers with the Airplane mode many times and the issue continues to happen at random times. It is really inconvenient. Suggestions?
Technical details: I use the stock 4.1.1 Rom that comes with AT&T S3. I do have LTE in my area.

And now it has happened 3 days in a row but at different times of day. This is a huge problem for me as I use my phone a lot. Any help would be appreciated

You still have your IMEI number via settings -> about phone -> status?

TRy making sure yiur not in airplane mode. i was stuck in airplane for a week ._____________.:cyclops:

That's weird. Re-seat your SIM card, if that doesn't do anything then take a trip to your nearest AT&T store/dealer and have them swap out your SIM card and see if it still occurs after that.

I had a similar problem a while back and it happened to be a network problem with my carrier. Gave them a call and all is fine now.

It happend to me too. I went to att store and get new sim. No problem for last 15-20 days. Looks like i got stronger signal too.

Just to give anyone interested in this an update:
I went to the AT&T store today and told them my issue so they told me to go to the nearest AT&T device support center (which was really far away). People over there told me they heard about this issue many times over the past couple of months. The guy working there had a S3 and said he has the same problem. They received an email from the higher-ups this morning specifically talking about this random outage thing I have and that they are currently working on it. They were told to not exchange phones or sim cards because of this since it wont help. The issue involves a combination of Network and Jelly Bean software problems and happens on all new LTE devices that have Jelly Bean from AT&T. They told me to check periodically if there is a solution.
I guess I just gotta wait. Unless someone recommends a ROM that is not based on the latest AT&T jelly bean?

Bumping it up, both me and my wife have had this happen. From what im read its a pretty widespread deal.
Anyone know of a work around at least until they fix it?

Keep us updated
Same problem here - switched from Verizon to AT&T last month and started noticing this problem a few weeks ago. Back then a Google search didn't find much on it, but this thread looks promising.
Just to add my two cents: I'm on a rooted S3 with task650's AOKP (4.2.1) build 12.23.2012 (link). Made sure to flash the modem for my phone (I747UCLI5 from here). Problem: phone randomly won't receive calls or texts. Sometimes calling someone will fix it.
I read somewhere that on AT&T, calls and texts are received over 3G and sometimes phones have difficulty switching from 4G. Anyone know if this is true?

Do a full wipe /system, /data, /cache, /dalvik cache. And your problems should be gone 9 times out of 10 that's usually everybodys problem

Seems to still be working fine.

I started a thread on this also and just yesterday received some info from AT&T tech.
http://forum.xda-developers.com/showthread.php?t=2123974

guys,
it is an ATT issue,
here is a temp solution for a fix:
1) With phone on, take off back cover and press your SIM card so it releases from the spring. It won't come all the way out as it's blocked by the battery. This seems fine - I didn't bother trying to force it out as I didn't want to break anything...
2) Once you see the message that the SIM card is removed, go to the dialer and dial *#2263#
3) You should see a menu with band selections. The current setting is "Automatic". If you switch to "GSM All", you will be EDGE (2G). If you switch to "WCDMA All", you will be on HSPA+ (3G, though AT&T and others call it 4G).
4) Press the SIM card back into place until it clicks. For whatever reason the phone will not recognize it until you reboot. Upon reboot you should see your new setting in effect
please see, post, comment here:

[Q] Problems with Mobile internet

I am facing a very peculiar issue that makes my mobile internet dysfunctional. Whenever I switch from 2G/3G to WiFi and then switch back to 2G/3G from WiFi, the internet refuses to work unless I restart my phone. Once, the phone is restarted, it works like a charm again till the time I switch to WiFi again. Sometimes though, 2G/3G would not work even if I do not switch to WiFi. Also, rarely, it still may work even as I switch back from WiFi to 2G/3G. This issue has plagued me since a long time and is sometimes accompanied by call drops.
I took my phone to a Samsung Service centre but it wasn't of any use. They do nothing except reflashing the stock rom. It did fix the problem for a while but in an hour or in a day(or in some random time duration) the problem resurfaced. I took my phone to the service centre, just to get this problem fixed. I have tried switching between different modes in settings: GSM/WCDMA/auto etc
I also tried contacting my mobile carrier and got my sim card changed. Therefore, the mobile carrier is not at fault (Internet works flawlessly after I restart, remember?). How do I fix this? It is really irritating to restart the phone every time I need to use the internet. Please help! :-/

Maybe try flashing a different modem. I had various data and call issues on my i9300. After flashing 10 or so different modems I found one from aveuropean carrier worked best. Im in the uk btw

Thanks for replying thedadio!
But I've never flashed a modem before and have no clue which one to choose. Is it same as flashing a custom rom? Also, can I brick my device while flashing modems?

Yes its similar to flashing custom ROM. What ROM are you on and what modem are you on?

McLaren__F1, I am on stock 4.1.2. Also, I just tried flashing DDALJ1 modem (As I'm from India) and Perseus kernel. None of these steps helped me in any way. Still the same issues. :-/

Which is your network provider? I had the similar problems when I was on docomo..nw ported to airtel nd problem solved.
Btw did you try some other np's sim?
Sent from my GT-N7100 using xda premium

I am currently using Airtel (Prepaid). I haven't tried using any other np's sim though..

I have the exact same problem. I am with optus Australia. I tried different modems, different ROMs but all have the same problem. I have sent mine away to be replaced and am still waiting for the new one. Very frustrating problem.

I'm not sure if they'll replace mine. It has been almost 6 months since I bought it..
How do I solve this? Any clue anyone? :|

My Note2 does this sometimes & only fix is a restart.

try soft format may its helpful

Not a fix, but toggling airplane mode on and off does the job for me.
Interestingly this happens to me only when leaving one particular WiFi access point.

i got exatly same proplem, 3g not working after leaving wifi of my workplace, but when im home i have no proplems if i decide leave my home network.
could it be related to radio type wifi has?? my workplace still using old hardware with radiotype of .g and leaving that network "kills" mobile network and i need to reboot phone, but my home network is .n and im not having proplems after leaving it. if its related to wifis radiotype it should be easy for someone to write script which reboot mobile network after leaving those wifi networks.

No one has a solution for this problem on XDA?

Did you use the NFC to scan anything by any chance? I don't know if it could be related but my phone started to have issues around the same time I bought some NFC tags and started programming and scanning them.
I still haven't got my replacement phone back yet. But I'll let you know if it still has issues in my problem spots. Than we'll know if the problem was with the phone or just this model.

Ohh, okay..Eagerly waiting for your response! *Fingers crossed*

Tested replacement phone today and the problem seems to be gone. The signal was actually stronger than all my previous phones.
This issue could be a hardware problem as from what I have searched on the net it seams to affect only a few people. I just hope if I root the phone the problems don't come back.
Maybe you could try send it away for repair if they won't replace it.

Looks like I spoke too soon. The issues are still there. While waiting for my replacement phone I was using an old HTC wildfire and had no issues with the data connection so it must be an issue with this model.

[Q] WCDMA Mobile data issue.

Hey everbody. this is my first post on here. and I have a really annoying issue.
OK, i bought an unbranded Galaxy Note II N7100 4.1.2 jelly bean couple of months ago and that issue seemed to be there since the beginning.
It's that when I'm connected to internet through mobile data on WCDMA, all of a sudden the "received" signal (orange arrow) won't flash any more while green arrow flashes every two seconds and i have no internet access no matter what i do, the only thing that can temporarily fix this is that i restart my phone and then the internet is perfect again for a not certain interval of time and then the issue happens again, it won't come back until i restart the phone again.
Sometimes it could stay for 12 hours before it happens and sometimes i could keep restarting my phone every five minutes, it's really annoying.
I've tried all the known tricks like hard reset, deleting all apps, i disabled so many services or apps that may cause this problem, I disabled all syncing apps, i deleted, re installed APNs, i changed my SIM card and finally i subscribed for another network provider and it still happens
I'm really at a loss, I don't know what causes this problem.
Is it a hardware issue? but if it was a hardware issue, it wouldn't work at all even after restart, right? is it some bug in the built-in 4.1.2 jellybean?
And i also may say that i receive calls normally, the WIFI works perfectly and the GSM mobile data works all the time no problems, it only happens on the WCDMA ONLY or the AUTOMODE.
The H , H+ or 3G sign is up there but the orange arrow all of a sudden won't flash and no internet access at all untill i restart the phone.and this issue may start to happen even if the mobile data is off all day and when i turn it on BOOM the issue seems to be there even before turning it on.
I hope you guys can help me with this...thanks

Hi,
I am not sure if this thread already exists but I am a bit caught up with this issue with my HTC One X(Arabic Version)
For the past One month I have been facing the issue initially I thought it was due to my old SIM card so I replaced it & still the issue exists.
What happens is that even when the signal bars are full and seems to be connected to the network I am not able to make phone calls, send Text messages or use the Mobile Data in short no network usage.
This usually happens when I am using the Mobile Data when suddenly it stops functioning but I dont get notified as the Network bars are still good enough.
The only way to get the network back is by restarting the Device.
I am using a Custom ROM.
Will going back to Stock help or this is a Hardware Issue???
A prompt reply will be really appreciated as the loss of network is causing delays in my daily works..
Thanks in Advance!!!
