Hey guys, I am very confused as of recently. I noticed that for a few minutes (3) my phone lost all signal. It was strange so I went and checked my imei. And its gone, it is the dummy one. Then without a reboot my signal came back and has worked totally fine for a few hours. I can surf the web, send texts and call. I am also posting this over 3g aswell. Even without an imei. How is this possible?
I am curious from a technical point of view.
Thanks

It might be that modem reads IMEI data only once at the startup. And you will not be able to use cell networks after a reboot. Just guessing...

For the past day I haven't been receiving any texts. I've tried 3 different friends phones on 2 different networks and 1 on the same network. I can send texts fine though.
A couple hours ago I tried calling my phone from a land line and noticed it goes straight to voicemail. I can make calls fine as well.
All the settings look fine on the phone, is there any special codes to enter to further check things?
Bells customer service is gone 'til Monday....
did you unlock the phone, or using any TurboSIM card unlocker?
Stock rom, not rooted or done anything like that. The only new apps I can remember using yesterday is the bluetooth module for astro file manager and trying the bump app with an iphone. Does that work by the way, android/iphone bump app? It wasn't for me.
Also, a reset to stock from the privacy menu hasn't helped.
yes i have bump installed, but so far not seen any iphony user with bump to try it on
are you able to receive phone calls if you put your sim card on another phone?
Finally got the number for data support from one of the local stores and they were able to fix the issue which was something on their end.
Yup, that just sounded too weird too be a phone issue

Bell has been having outage problems. It's probably due to the surge of new users they're getting because of the SGS. I called them up and they reset it for me or something.
I have the Bell i9000M unlocked and used with Rogers SIM. Nothing else has been done to the phone besides installing apps (got the sd corruption on my first i9000m after using Odin and didn't want to go through that again).
Haven't had any problems for over two months but in the past week, I have dropped calls and could no longer make calls again until I restarted the phone. I have dropped calls before (there's always a couple of areas on my drive home where I drop calls using any phone) and have always recovered. But just this past week, I can no longer make or receive calls after a dropped call.
Sometimes the status bar shows the blue circle with a slash, but that changes to white bars. But even with bars I can't make or receive calls. When I check *#0011# it doesn't show that I'm attached to a network.
I can go to an area with strong signal and leave the phone for hours but still cannot make calls. The only solution for me is to restart the phone.
Anybody have this problem and know how to fix it? I've been searching for days but haven't seen a solution.
Thanks,

I had the exact same problem on my first 2 I9000M's. The only thing I ever found was to replace them. It was annoying as hell and made the phone impossible to use sending or receiving calls. the second one was JH2 with the 3BR fix. Texting was perfect as was the internet (3g).
I searched and searched as well. But I was talking with a bell guy about it and he said it may have to do with an IMEI issue they have a master ticket open 3449667. I know you are on rogers now, but hope that helps in some way.
Thanks, it is very frustrating and dangerous since I'm usually driving when this happens. Unfortunately my 60 days are up and I can't get a replacement. There must be a way to fix it since it was working before. Maybe a SIM issue? I'll keep searching and hoping and if nothing, then I'll do a reset before sending for repair.

Just to update, I got a new SIM card and I don't have the problem anymore.
Hello,
I'm on EE UK network and I keep getting text messages that i've missed a call even when i'm at home where i'm connected to wireless and also have 3 or 4 bars signal.
don;t understand why this keeps happening. I try calling my phone from another mobile and it works OK.
Any one know why this might happen?
Thanks
Are you sure its recent calls? Depending on your carrier it might log it and send it as a reminder later or something like that.

Problems like this are quicker to fix by wiping your phone, if you have data you want to backup either use titanium backup or do a nandroid backup (build into CWM)

I've wiped the phone but just found the problem still exists, any help with this will be appreciated. It's very annoying that people cant get through to me.
I read somewhere that the problem might be something to do with the 4g network. the network needs to switch from 4g to 3g to receive voice calls and if it doesn't switch quick enough, it results in a rejected/unconnected call but gives me a text to say someone couldn't get through.
is that possible?
I also have the same problem. While I was holding my device which had three bars of signal ,I was calling my number from a friend and kept getting the msg that it was not available, ..after 2 mins I received about 5 "missed call" messages. I think it's problem of EE though.

Hi Guys, new user long time lurker here.
Getting to the point, my HTC One was doing amazing until I woke up this morning. It is currently running ARHD 3.2, the stock google rom and I've been loving it. I was getting mms last night, woke up in the morning and I couldn't send or receive them. I have tried everything. I wiped it, flashed it again, wiped it, then (the weirder part) restored a backup of ARHD which was the tweaked Sense rom, I believe it was 12, and I still had the same problem. i've removed APN, added them, changed them, and still nothing. Any ideas? I've also changed my messaging apps, moved to Textra, and still nothing. Logically it seems as though something has been removed or edited in my phone that causes the block, but even a restore which was from 32 days ago still cannot send mms. I'm stumped. Also I have made sure my data was on and all that stuff.
Thanks guys, I appreciate anything you can help me with.
Someone posted what sounds like the exact same thing in the Android forums but this site won't let me paste the link. Carrier is AT&T and they were stumped.

Call your service provider and ask them about it. Or test another phone that's on the same tower, if capable.

I guess ill try my parents phone. If nothing changes I'll call the provider tomorrow.
EDIT: it seems to be a tower issue since my mothers phone can't send MMS either. It's strange because it had the same problem at work, but that was only ten miles away. But in a city area. Quite frustrating.
This is the thread. Sounds similar no?

Sounds similar. I have absolutely no other issues it's just mms. internet is fine, everything is a ok.
Exact same problem with my unlocked htc one since last night. Was in multiple group chats and all of a sudden I couldn't send or receive any mms messages to or from the groups. Problem is persisting this morning. I'm in the NYC area and wondering if there are network issues. Where are you located?

Lower bergen county, near Newark Nj. seems to be trend happening here!
I've been on the phone with support for awhile now, nothing has changed on my phone, they said they reset my network when I turned it off like twice, now I can receive them but not send them.
Late update, but this happened to both my phone (Trickdroid 9) and my girl's (stock, unrooted) that night. Working now, but it was annoying as all hell.
New issue. I can now send and receive pictures! awesome! Bad news: while I am connected to wifi, I do not have anything other than minimum service, so I can only text and call! I understand that the wifi is being used, but I can't send or receive mms for example if i'm on a wifi network. is it as simple as fixing an APN? or changing it? Anything possible? Searching only gets me people who want to turn of LTE with wifi so I'm stumped!
I am on Three network in the UK and they have an app that you can use on wifi when no signal is present (https://play.google.com/store/apps/details?id=com.hutchison3g.threeintouch&hl=en_GB). Unfortunately, it doesn't run on rooted phones and no root cloak app hides root from detection. I have come across this page https://redfern.me/bypassing-root-detection-in-three-intouch/ as a how to change the APK to bypass root restrictions but as I am clueless I could not do this myself.
Is there anyone who would be kind enough to do this for me (or does anyone already have this APK?).
Thanks in advance.

Just wondering as you're also on 3 with an N6... I constantly get data dropping out and have to flick into airplane mode and back again to get it back. I think its a lollipop issue because i had it on my n5 after the update. It happens on the stock rom and on PureShamu. That damn exclamation mark on the signal symbol is driving me nuts! It happens everywhere, too not just on a few towers...

After talking with Three customer service they eventually sent me a signal box to circumvent the no signal issues I was having at home.

I think its because the phone is hunting between 3G, H and 4G all the time....
I've noticed the same thing. My data connection will just show no service. But what's weird is that if I turn my WiFi off at home it will then pick up a signal. WiFi on and the signal drops again.

I had this on 3 UK with my nexus 4 on 5.0.0. Clean flash of 5.0.1 fixed the issue.

Sorry for the off topic, but I've got one of those signal boosters from 3 with my nexus 5. Back story, the mast here failed a lot last year. When its working, signal here is fine son I told them i don't want a box...
They sent it anyway and I've had no end of problems with it. It all works fine, I get great signal with it and the box lights up to indicate its connected to the internet. But randomly, it wont send calls to my handset... So I miss calls (without knowing)... Worst time was when my Dad came to visit my village for the first time and was just wondering around for ages trying to find me... Gah

Sorry to read about your issues (I am sure your dad was thrilled too!)... I'm hoping that I don't get the missed calls issue and at the moment I am more than happy to get a signal in my house.

I had the same issue with missing calls and just receiving a missed call notification. I've found a work around; when I arrive home I place a call from my mobile to my land line and then it seems that for the rest of the time I am home the mobile is connected to 3 through the homesignal box.

That's interesting.
What's strange is, i was definitely connected to the box. In fact, I don't even need the box usually but there was a brief outage on the mast so I turned it on and forgot to turn it off again. The network worked outside of my house, but when I came home and connected, I couldn't receive calls not even missed call..

I have a signal blackspot radius of around 800ft from my flat. The only problem I've had so far is when I upgraded from a Nexus 5 to a Nexus 6 I needed a nano sim and of course the homesignal box wouldn't recognise the new sim card!
