I was in an area with really spotty coverage. Its in the middle of LA by Hollywood but for some reason Verizon's signal is very weak on this street. I was trying to use the internet on my phone and watched as the signal meter went first from 4g to 3g then switched back and forth between 3g and 1x to no data signal at all. In the meantime my phone was getting really hot. I would reboot and the phone and it would still get hot again while I guess trying to find a 4G signal. The heat was not from the battery but the area under it where the SIM and SD card, as well as the CPU's I think, are located. I was on that street for a couple hours when I left my phone could not pick up a 4G signal at all again. I tried everything I had to try last time my SIM card died. Reboot, reboot and wipe cache partition etc. Anyways I made my way to the verizon store and got a new sim card. Took about 30 min and I did NOT have to do a factory reset. The phone worked good for about an hour until I went into a parking garage where the data signal was lost. Again my phone got really hot and when I got back to ground level alas no more 4G.
Is this a software problem? or hardware?
I am running stock verizon android with GOLauncher. I got the MD3 update today with the new SIM card for that one hour I had 4G.

So I have been for the past week, at my house, having about the worst 4G reception ever. It shows 4G in the status bar, until I actually try and connect to any internet service, and then it disappears. Well this started on my second Thunderbolt, so I assumed something was up with the phone, specially since I unrooted the phone, and the issue was still there. So I went and exchanged my phone today. I noticed that the issue remained. Brand new phone, at my place of work today was pulling 20+ down from speedtest and then I go home, and even outside my house, it is loosing 4G everytime you try to do anything on the internet.
I noticed only one difference. My PRL changed from 15008 to 15011.
So figuring my new phone is probably fine from a HW standpoint, I went ahead and rooted this phone, and I noticed something weird. Everytime I boot the phone, it switched between two PRLs. It either has a PRL of 1, and then reboot and it then will have a PRL of 15011. Rinse and repeat.
I also noticed that in the same location that it used to be signal strength was around -82Db, and is now closer to -95Db.
So I am going to call Verizon tomorrow, and see if they know if a tower is down, etc, or see if they can check into it, as my phone is only usable at home on 3G, which is the same reason I paid my ETF on sprint and left for verizon, because I could get LTE in my house.
I even tried Das BAMF 1.5 and then flashed the radio update, and there was zero change in anyway.
I am going to assume there is a screwy tower nearby that is causing my problem, but if anyone has any suggestions let me know!
my phone acts the same way around my apartment...
i think they must be messing with the towers still. specially cause we haven't officially got 4g here yet.
have the same problem up in Northwest Columbus - 4G has been going in and out for the last two days for me - figured it was just the tower, 3G is absolutely fine.
I am currently running Ninja-0706, radio 26.06.06.30_M.
Intermittantly, my phone will drop out of H and start cycling through all the connections, edge, gsm, 3G etc. After cycling through, it will go to no connection at all where you see "no service" on the screen. And it will stay like that for several minutes, no matter where I am standing in my apartment, or even if i walk outside. Then all of a sudden, it will pick up H, full bars and it will stay like that.
So far, this issue has only happened a couple of times, within the past couple of weeks, and at my apartment. I have full wiped and flashed different roms, and reflashed the radio after the first time this happened, so this issue cannot be blamed on current said rom. This has led me to suspect that maybe there is an issue with the tower in my area. Twice I have called AT&T now about this issue. Both times they claim there have been no outages or issues with the towers in my area. They also claim that the closest tower to me is about 1 mile away, so there shouldn't be issues as such with a tower so close. I don't know anyone in my complex who is on AT&T to see if they are experiencing the same issue. So AT&T seems to think there might be an issue with the phone and i might need to do a warranty exchange. Any ideas before I flash back to stock and exchange it out?
While mine doesn't go that far, it'll cycle between H and 3G for no apparent reason.
Mine does weird **** sometimes, too, on Tue 04_11_M2 radio.
Just today I was sitting around browsing via WiFi, and bam, no signal. Most if the time it'll kick back in after a sec or two, but it stays like that until I intervene by toggling airplane mode, then, it'll be back to 3-4 bars or whatever.
Second time its happened over the last month, so no biggy.
In my house I get lots of signal variations overall, which I guess should be expected.
Well, my phone has done it twice since OP. I just flashed back to stock and downgraded to s-on. I'm going to see about an insurance claim.
Update: Just got off the phone with AT&T. They said that this issue would need to be handled by the warranty dept. So got back on the phone with tech support and they suggested that I go into an AT&T store and have the sim card replaced before they replace the phone, as the sim card itself might be causing this issue. It seems plausible because the sim card is needed for a connection to the network.

Ok. So I ran into a serious issue and it most likely has something to do with the 3G radio.
Here's what happened. Phone was down to about 15% batteries after some Youtube and Angry birds. I was at my folks place and the cell signal there is not as strong, but still a bar showing. I noticed the phone was quite warm, but thought nothing of it since I was using Youtube/Angry birds. Check a few emails and noticed the batters quickly dropping to 12% within a few minutes and noticed Battery Status Monitor was reporting 990mA draw. I was alarmed, but didn't think too much about it and went to have dinner with the folks.
about 30/40 min later after dinner. The battery was dead. Didn't have my charger with me, so I didn't plug in for another couple of hours until I got home. Plugged in, booted up, everything was fine, except it would not connect to cell service stating "No Service". I then tried a bunch of things, rebooting, swapping out the battery, swapping out the SIM, but no avail. Swapping the same SIM to my old HTC works fine and connects on AWS 3G network.
This morning I tried another SIM that not on AWS, and it connects (assuming on 2G/EDGE network). Swap back in my original SIM and back to "No Service" (my provider only has 3G AWS service).
So at this point, I'm pretty convinced I have a hardware problem so I restore the stock Froyo ROM to return my phone...then magically, I'm back alive on the 3G AWS network!
Someone tell me what's going on!
I haven't tried to reflash CM7 again. Quite frankly I'm quite scared this may not be hardware problem and maybe a software issue instead, and may be stressing the 3G radio.
Help!
Hey everyone, I just bought the universal 8 gig Moto G 4g lte. I'm super pleased with the phone except it seems that my phone is constantly switching between LTE, H+, and H. I'm currently using Straight Talk with one of their AT&T sim cards. Sometimes I'll pick the phone up to make a call and it will say no service. It only lasts for maybe 20 seconds, but after it says no service and the time has passed it will show bars again. It's almost like it loses connection with the sim card or something.
I've spent several hours reading about the problems people have had with the switch to KitKat. My phone never shows the "no sim card" or anything of that nature. The triangle where the bars should be just goes completely empty. I'm just curious if this is known to be a software problem and not a hardware problem. I just came from a really really low end smartphone that would cut itself off on a daily basis. I need this phone to at least maintain normal functionality for a while. I don't have a phone to put the Straight Talk sim card in to check and see if it's the problem.
I don't really want to send the phone back, even though I've looked at the Nexus 5. It's a little bit out of my price range for a phone. Thanks in advance for your help.
Hi,
I initially started with a OnePlus One and it came to a point where I would lose reception (Both data and mobile) maybe once an hour. The only fix was to restart the phone. I got fed up with it so I ended up getting a new phone, the Samsung Galaxy S7. It's been 3 days and I haven't found any problems, however, this morning I found my phone to have no reception. I restarted it and it started working again.
Could this be a SIM card problem? WiFi works fine.
Thanks
Not sure about the OPO but i had this happen to me where i lost reception for no more than 30s.
For you to restart the phone to get a reception is news to me and honestly have no idea.
I don't know how easy it is for you but with my operator it is very easy to just pick up a new sim card and ether have the shop to register the new card or do it by myself online. If the card is the same as the one you used with the OPO a new card would be the first thing to test. I have heard of lost reception problems were a sim card has been the culprit.

Is it the same SIM card from both phones?
Something has to be the same between them, either the SIM, or if it is a different SIM, then your location / surroundings / interference

Same SIM card. My location and surroundings don't affect when I lose reception. It just seems to be random. Both me and my girlfriend have the same carrier (Kodoo). I'd be sitting by my desk for a couple hours and have full bars and suddenly lose reception. Then restart my phone and I get reception back.

I'd request a SIM replacement, see if that fixes it, unlikely to be the phone if you have two with the same problem using the same SIM
