No service - problem

Yesterday I got my brand new Diamond and when I got home the first thing I did was update the ROM from the htc website, everything went ok, I made a call, did some settings and let it to charge, later on I saw that I had No service with the SIM that I had in it originally, I started freaking out of course, rebooted, did soft reset, did hard reset, I even reinstalled the flash to make sure everything went ok. The signal did not work, I mean it got the signal, after 2 seconds loose it, after 1-2 minutes found network again and after 2 seconds loosing it and that was going on. So I tried a SIM card from another network which worked, then I tried a friends SIM from the first network which did not work. Eventually, I selected the network manually on my sim and it started up but only with 2 lines on signal. It seems to be working since last night with 2-3 lines signal but I suspect that could be that we have low 3G coverage over here, anyway.
Has anybody else encountered this problem ? Why do you think this happened? Should I rush into the store to take it back or is it some settings or software?
Also I have the rom from the htc website, is there any other version that works better?
Also could anybody give me a quote on the battery life because I am uncertain of it, I am not pretentious, if it holds up 2-3 days with normal use(phone + a little wi-fi and whatnot) then I am satisfied.
Thank you.

did you take your sim out while you flashed the ROM?

Umm... I must be stupid or something but I didn't, I must say this is not my first phone flashing so I don't know what was in my mind, did I damage the SIM or what ? It seems to work now though...

I've never flashed without taking the sim out, having said that I know people who have flashed with the SIM in and havn''t had a problem. But then there's a few that have had issues when the sim was left in during flash. Good to hear that it's working again.

If I encouter the problem again do you think flashing it without the sim will solve it ?
Also what ROM do you have? Do you recommend one that is better than the one from the HTC website?
What is your battery life average?

well it's hard to know - if you flash again be sure to take out the sim, but if the problem persists maybe you need to get a sim replaced. I work for Telstra here in Australia and a replacement sim costs $30. But if we "say" the sim has "failed" there is no replacement charge.
I am waiting for elite 2.5 rom which is due to be released any moment here:
http://forum.xda-developers.com/showthread.php?t=403296&page=18
My battery life is pretty good - it holds up 2-3 days with normal use (phone + a little wi-fi and whatnot) but if I do alot of browsing I need to charge every day.

I understand, well, what it was strange is that it didn't work with any other SIM I tried from Vodafone network, I tried my friends and another one but worked fine with a sim from another network during that time when I had the problem.
I will keep my eye on it and hope it doesn't happen again.

Do you use Yahoo by any chance on your device? I get the e-mails perfectly with the imap server but I can't get to send any e-mail with the smtp server the phone has configured automaticly...

probably the default settings for yahoo are diff...i think it requires a reg change possibly to fix? not sure....
regarding the flashing...i've flashed my diamond around 7-8 times, not sure...pretty much tried every cooked rom here cept for 1 or 2 and the official WWE ones...never had any issues with flashing (and my sim was inside the phone every one of these times)...

it happend to me
it happend to me, in places with low signal... hapend a lot
what solve it was flasing the radio rom 1.00.25.05 i think it may solve all your ploblems.
please let us know
pd. i had signal problems with al the older radio roms even the 1.00.25.03

thanks jr-daza, i will search for the rom to flash now.
is there a place on the forum where i can download it ?

No Network to call but 3g works(Solved by fluke)

Got a new problem with my G1, basicaly I used my phone placed it in my pocket went out then when I next checked my phone I had no signal, I didn't take too much notice of it. When I got home and also there I had no signal, did the obvious rebooting, no joy. Then I did a wipe restarted the phone, still no signal now this is the strange part I had 3g because my phone let me sign in also started syncing my phone contact. I can browse on the net also download from the market but when i dial a number I get the message Not registered on network. So when I went to settings/call settings/network operators/available networks clicked on t-mobile it says Your SIM card does not allow a connection to this network. Then just for fun try it with the other network operators same message. Also my sdcard was reformated.
Then I downgraded to rc7 (dreaming.nbh) rebooted no call signal but can browse and use market so I've updated to android 1.5 ota still no joy any ideas I planing to take to a t-mobile store let them check it also has anyone else had this problem before.

Sounds like a problem with your network, not with your phone. Either that, or your SIM card is fried. Assuming you're on T-Mobile from your post, you need to contact them for a new SIM card (you can do this inside any of their stores.)

Just to prove my sim is working fine I have put my sim in an old nokia and just rung customer service and got my balance this proves my sim is in working nic.
On the G1 I can't call what so ever or send a text just getting 3g coverage.
Thanks for the advice.

It really may be the SIM card or the SIM card reader in your phone (more likely the SIM card) it may work on another phone
try cleaning the contacts (the ones on the phone, not the ones IN the phone) ?

Call customer service and ask them to take you off whatever tower your phone is now on? suposebly pulling the battery will do it to.. Also get Anycut and make a short cut to phone info an toggle radio on off?

same problem occasionally

i'VE had the same issue, occasionally, I'm fairly certain its the sim card, not the phone. you can take the battery out, pull out the sim card, clean it up (don't use watter or anything that'll scratch it of course) and put it back in, make sure its securely in there, and boot up the phone, however, I've also noticed that sometimes in the middle of the night (like around 2AM to 330AM PST) sometimes cell coverage gives out for t-mobile where I'm at (friends confirmed), if you only just recently recieved 3g in yoru area, they are doing maintenance to get it up and running perfectly, so don't fret too much
EDIT:
Another thing I did was made sure to mess with the APN settings. dont' edit them, just try and change your APN from T-mobile to ATT, wait for it to say "not supported by sim" and then switch back over to T-mobile, that worked for me twice now

I'm having this same problem, only I can't surf the web or use the market. :\ Any help would be GREATLY appreciated.

Sorry to reply so late but the probem is now solved, this is what I did, I took out my sim card out the phone put it in an old phone to see if my sim had any issues but I forgot to take out the sim and put it back in my g1 went sleep.
Next morning put the sim in my g1 and all is fine got connection and all functions working, then waited a few hours no problems at all.
So I rerooted installed the danger spl and custom rom and the probem has just vanished, haven't got the slightest clue why that happened or what caused it.
The sim is new just under a month old lost my old 1 uk t-mobile charged me just under a £10 for a new 1 even if your on contract thiefs

its probably
A) the SIM got dislodged or
b) your G1 contacts were dirty.
All the above could cause the phone to not read the information on the SIM
Blowing the dust out/wiping the goldcontacts where the sim goes, and tightly inserting the sim might help, grandmegabosses

"no service" No voice...but Data working sporatically??

For the last few hours my G1 has been showing me the X above the bars.
Ive tried restoring an old image...tried data wipe/reset.
All end up the same.
Selecting my network (TMOBILE) has been an adventure.
One of the following occurs
The menu itself gets stuck on airplane mode.
sim card not authorized on network
cannot connect to network
Ive rebooted numerous times even when bars/data look like theyre back , Ill make a call and it will drop the call, then right back to the X.
What compounds the oddity is that even with the X Ive gotten data to work for the most part. Sometimes it will sometimes it wont. Im extremely confused if this is my SIM card or the G1 itself.
Cus Serv online said to go to a Tmo store for a new sim. But my schedule may not allow that until Fri. I dont have any other sims or phones to swap and try either.
Any clues what this could be ?
G1/TMo/Offical Tmo Donut ROM from this forum.

Crazy data transfers could be browser cache? Very odd. I would go with what customer service says on this one.

Reflash radio
Just reflash the radio - get the official one from HTC developer site or whereever you can find it and reflash it using recovery ( I hope you have recovery 1.4 or Amon-ra recovery). You can try to take out your SIM and examine it closely, and maybe clean it a little. Just take it out and put it back. Then reflash radio and see if tat works.

Stopped short of flashing the radio.
I wiped and installed Cyn 4.19999 same issue. Rebooted , wiped..then reception came back.
Maybe it was ROM Im thinking ? Wiped restored my previous save (TMO ROM))and everythings working again except for Picmail.((which has been a reoccuring problem)).
Tmo says to go pick up a new Sim card to see if it helps. I guess theres no harm in doing that right ?
Ive never flashed the radio since Cyn and The Tmo ROM dont require it. So its still on stock. Would the pic mail being sproatic before and after this be a Radio problem as well ?

Yes , PicMail=MMS
Its been buggy for me for awhile.
Im wondering if all this is some wonky Simcard.

Dont stress it. It happened to me yesturday for about a couple of hours. I think TMOB is workin out some signal issues. I had the same exact problem along with 10 of my fellow network friends. No rom bugs or flash fcuk ups. It'll restore it self normally unless you truely did it to your self while flashing.

Could very well be.
Thanks Garz.

[Q] HELP: Lost cellular data and service

Anyone have a fix for this? On Verizon and after almost 4 weeks I have lost my cellular service and data. I noticed when I went to check up on my phone right now that it was finishing a boot-up screen and then never had any bars at the top. Dug deeper and found no service at all. Wiped dalvik and cache and seemed to be bars for under a second and then gone. I am on sensei kernel and am thinking about doing a factory reset and reverting to stock kernel. But I really don't want to lose the benefits it came with.

Well, this is odd. After a month of perfect service, I suddenly cannot get LTE, only 3G. Even nandroids of prior ROM's will not boot into LTE. Is VZW LTE down or should I do a total clean reformat? i do have factory images and everything is backed up. Just a pain.
Very strange. I was flashing various ROM's (CM 12 based - am testing for someone) and at one point pulled out SIM and replaced it. I checked to make sure it is seated right since then. Again, no longer get LTE.
Was on Sensei kernel as well. Let me try flashing stock kernel from ROM first. EDIT: NOPE! Flashing the stock kernel from the ROM did not do it. Looks like total reformat/flash is next!

I just got my Nexus 6 and I am also on Verizon and had the cell coverage drop too. I backed up my apps with titanium backup and did a factory reset and signal came back. I only had it for a day and went to Canada and on my way back to the US I noticed the cell bars were gone. I was just rooted and boot loader unlocked and otherwise stock. I read online that others had this issue when they got to places in the US that had little or no signal. I also noticed that under cellular network settings it loads up with Global under the preferred network type even though it has an option for "LTE (recommended)" and if you choose LTE, global is never an option again until you do a factory reset and it loads with it pre selected. With global selected it works perfectly with calls and LTE, so not sure what that means or if my selecting LTE made it drop the signal after going back from Canada.

Yep, total flash of factory image fixed it. Sigh. Early enough in the day for me to get everything set up again.

Same. About to do it too... I've done too many factory resets with this already. Kind of annoying.

I am in the same boat. Had no problems until I flashed bliss 1.5 then was stuck on 3g. Tried a clean flash of Slim and still stuck on 3g. I will try a stock rom but I am not very hopeful at this point. It's looking a like a reformat here as well :/

Ended up having to format everything and start from scratch again. I'm running a stock ROM now and in weary to try another cm ROM

Don't know if it'll help, but try LTE Discovery app in the Play Store. I use it from time to time to reset my data connection.

Having the same issue, running CM12 daily, have been for a week or so. Midday today it drops LTE, 3g data was working, then a few minutes later to no data. I didn't change anything, nothing new installed. I did reboot the phone at some point before this but that is all...
My only fix was to backup via trwp, restore stock rom, factory reset, reboot & let sim activate, then restore cm12 via twrp... it's a 20-30 min fix all said and done.... pita
Maybe its something Verizon is doing, because I didn't change anything and then next thing you know no data. I hope it's a simple fix for CM12 but I see this popping up more the last few days. Hopefully someone will figure it out. I like CM and prefer it over stock but I am not going to do this multiple times a day just to keep CM...

I just checked and global is still an option for me. I've bounced back and forth, looking to see if anything changes..

Same thing has happened to me last night, lost connection to VZW cell and data. Looking at the field test menus, it seems like the SIM/device understand GSM but NOT CDMA anymore. So I believe the issue has something to do with that. Tried everything, but will nuke and repave most likely....also lost Global as well. and LTE Discovery shows GSM stuff nothing for CDMA
Tried the SIM in another device and it works so its not the SIM.

OK I tried a world of things to recover like some of you may have....its something in Userdata because if I flash everything but userdata it wont work. I am going to try and recover from the backup I had before this happened to see if that works....otherwise rebuild from scratch
will post back
UPDATE: So restoring a backup seems to be ok once you get the SIM back.

Having the same issue over here as well... After a month or AI of having the 6, now I randomly drop service where I would normally have full LTE. I almost NEVER get LTE now and am at most on H with a couple bars then it drops out again. Have also.noticed WiFi connection is very shakey.
Any one find a fix?

I had an issue where i couldnt get my phone to connect any network. Took me long rime to realise, that entering my PIN-number too fast caused the issue xD it unlocked the sim, but didnt let me connect any network... Dunno if this helps anyone, but definetly the most cryptic issue I've ever had.

Troubleshooting my wife's N6 here. Your PIN issue doesn't make sense to me because the phone should be connected to the carrier when locked. Are you talking about WiFi? Because that should be connected too when locked unless settings have been changed from their default (ie, turn off wifi when locked/asleep or something)

I'm talking when you turn on your phone and it asks for pin number to unlock your sim. Some how it seems that if you enter your pin too fast, it bugs the phones radio somehow and you can't connect to your carrier but if you wait like 5sec before entering the pin, it connects to the carrier and the (!) Mark goes away. Try rebooting the phone and see if it helps? Even I think its a weird issue
Edit: OK, just pinpointed MY issue. I have to wait for the "no service" text to change into "emergency calls only" before entering my pin or I don't have any service just the exclamation mark :/

Thanks. I told her about it and she will give it a try, or just remove the pin altogether as a test. It is a weird issue. She is missing important calls from her elderly parents at night and it is rather frustrating. Turning wifi off also seems like a bad fix.

[Q] N6 - No incoming & outgoing Calls, mobile data gone.

Having my Nexus 6 for almost a month. Things working perfectly in the starting(or after reset), but after two or three days, No incoming calls, no outgoing calls. No mobile data. Cant realy tell it as a mobile sometimes. Wifi is working good always. After reset, it is working properly for two or three days. Whenever it is not working, I am able to see a !-mark near the tower bar.
My mobile always connected to 4G when no wifi.
No Custom ROMS and no root. Plain Android given by google.
Anyone having this issue. Any suggestion?

Go get a new SIM.
Sent from my Nexus 6

I was begining to think i was the only one who had this problem!
Yesterday morning i woke up and to my suprise my signal bar had a (!) it it but it was still displaying my regual signal level.
I switched my wifi of and i couldnt get a data connection just the (!) sign. I got my girlfreind to give me a ring and see if a
call would go through which it didnt it just said that i was unavalible. I then desided that a reboot might sort the problem
but when i my phone booted back up i was presented with the holow triangle signal icon to say that i had to signal. I then
popped my simacard out thinking it could have just been a bit of dust on it. I gave it a little bit of a dust of and popped it back
into my phone and i was given the same no signal and emergency calls only yet it was picking up that there was a simcard inserted.
The day before i had flashed the alpha version of PA so my next thought was that this would be a ROM bug and went ahead and
flashed chroma which i was using prior to PA and i had had no issues with. Held my fingers crossed as it booted up but much to my
dismay i was greated with the same no signal problem but i went into the settings and searched for networks. Three was one of
the network it had picke dup so i tryed to reconnect to it but i got the toast to tell me i couldnt connectto the network and to
try again later. I checked the APN settings and it had automatically grabbed threes APN from the sim card so at this stage i was
completly baffled by them problem.
My next move was to try my sim in my girlfreinds phone and what do you know it worked a charm. As a last shot to check everything
was okay and i was upto date on my bills etc i gave three a ring and they told me there was nothing wrong with my sim and everything
was working as it should be and that it was a problem with my phone.
That brings me to the point i am at now completly baffled as to the problem and slightly angry at the 2 week old phone that had been working
perfectly up until now has suddnely desided to stop with no warning.
So you are not the only one and i expect their are more of us. I am going to flash the offical stock rom from google and see if that does the
trick but im not holding up much hope i feel like im going to have to contact google and find out where the problem lies.

i reverted back to complete stock using the image from there site to no luck so i relocked the bootloader and took it back to the carphonewarehouse and they straight swapped it for a new one which is working perfectly

My sim died after a month. My calling went out and then only lte worked no 3g. Got card replaced and it works perfect now. I have US Cellular.

I've posted this in few other threads also, but I had also problem where I only had tgt exclamation mark no matter what I did. I solved the problem by waiting like 5sec before inputting my pin-code. If I input my pin code too fast after a boot, it will open my phone, but won't give me cellural network. This seems to happen in every ROM I've tried

Hi,
Solved the issue. Working fine after enabling request for SIM Pin and set my sim pin.
Usually i disable sim pin lock to have uninterrupted boot. But with ROM this is not working.
Enabling SIM pin request solves the issue.
Is this problem with carrier or Android L?

I have not seen this issue on three devices I've owned with Lollipop. So it appears to be a carrier issue?
