I'm rooted running Gummy2.0. I had an issue a few weeks ago where I dropped all data connection for 36 hours. I ended up pulling the SIM card and reinstalling it and it fixed it. Now I'm showing a full data connection but not getting one, example showing 3 or 4g and my internet, market, and pandora not working. It is getting very annoying. It always comes back after 10 minutes or after I reboot my phone.
Is this a SIM card issue? I don't know how to diagnose these issues so any help is appreciated.
My wife has an unrooted thunderbolt and her data connection owns mine regularly:-(

So I'm not connected to any network, Edge or 3G. This happened a few days ago, and I guess to a few number of people too on HowardForums. Well it happened again last night, and it still happening now. Fortunately I have wifi here, but still no data network. Anyone know about this/why this happens?
May be a problem with your SIM card. Older SIMs can create problems with getting on a Network. My phone would drop its data connection all the time in a known good area (my work consistent 3G), swapped out my 5-6 year old SIM for the one packaged with the G1 and viola! no probs since.
i have the same problems happen to me about 4 times already and i just got this sim card less then a month ago
I searched and did not see anyone else experiencing this issue. I have a Black 32 GB stock rooted. It worked fantastic for about 2 weeks and then all of a sudden I noticed the following:
Day 1: No SMS received. I was on WIFI and had network signal in the notification bar but did not receive SMS that were sent to me.
Day 2: No Cellular Signal. I looked at the APN and it had disappeared. I attempted to add it again and reboot the phone and it wouldn't add. The phone began rebooting on its own and continuing with a bootloop after running for about 10 seconds it would reboot again. It did this throughout the day. I called Google and they had me do some soft and hard resets. After the soft reset the phone would connect right after startup then disconnect after 2 seconds and reboot itself. I hard reset the phone and relocked the bootloader and reinstalled factory recovery and it is still doing it.
Google has given me authorization for an exchange but I was just wondering if anyone had any ideas because I'd rather not be without a phone for 2 weeks.

I had a similar issue
I had a similar issue. After a month of functioning normally, my Nexus(rooted using CFroot, stock ROM, T-Mobile) lost the ability to get reception. First, it showed network signal, but cell access was not functional. A few hours later, bars dropped to zero, and it seemed like I could only get reception in the strongest signal areas. I would get signal sporadically when driving, but never when I was stationary. The phone never had problems with rebooting though.
After spending a day trying to fix it, factory reset, relock, flashing a factory image, I called Google, and they warranteed the phone.

It just seems so much like a software issue as opposed to hardware that it surprises me they are willing to warranty it... but I guess I'm not the expert.
How long did it take you to get your replacement phone?

I got a replacement phone pretty quickly. The phone shipped the day after I ordered the replacement, but YMMV.
Why do you think it was a software issue? The problem persisted after I switch back to a factory image. The replacement phone, running the same software does not have the same issue.

That makes sense that it was a hardware issue. I guess it could be a faulty radio or something. I'm glad to hear you got your device shipped so soon. Did you end up having to pay shipping?
I ran a nexus 5 for about 4 days and went through two of them both having issues holding a signal. Both phones would start with LTE and then drop to 2g go to 3g and then 4g back to no bars and then 2g and 3g. I was stock all the way and I wish the nexus 5 worked better. It could be a software issue as when I took the OTA to 4.4.2 it became worse. All the areas I was in while this happened were areas that were supposed to be strong for 4g and LTE.
That said I I need a phone that is a bit more reliable even though I'm on T-Mobile. I switched to the LG G2. It has a better antennae and doesn't keep bouncing between modes when in various areas.
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
To Those Who Know More Than Me (that's pretty much all of you),
I purchased an unlocked H830 to use on Cricket Wireless (and hopefully root, but that's another story). When I first popped in the Cricket SIM, it found cellular signal as well as data within a minute or two. All was well, it seemed.
But this weekend, a couple of days later, data began to not work in Chrome, Maps, the Google feed, ESPN app, etc. Here's the weird part: the signal indicator shows 3, 4, even 5 bars and 4G active. Speedtesting shows I'm getting 2-3 MBps--not great, but not unusual on Cricket. So why does the phone pull internet but not distribute it to the apps trying to use it? Maybe 20% of the time, data will work, but that's obviously not enough for a small business owner like myself who is out and about constantly. Calls and SMS work just fine, so I don't think it's a corrupted/damaged SIM card.
I have deleted and reset the APN a couple of times. I have restarted the phone. It is running H83020a, since I manually downgraded from c in order to try and root. Strangely, it now says no new update is found--are those locked to the T-Mobile network?
Does anyone have a solution to this? I'm quite frustrated. Everything else about the G5 (barring the complicated root process) is working fine, and I want this to be my daily driver once the data issue is resolved. Thanks!
I have had my oneplus for about 60 days. three days ago, when I was driving, I noticed my signal meter had an "exclamation point" next to it and I had no mobile data access. I messed around with it a bit and thought it was SIM card. I got a replacement today and no luck. New card, same issue. It occurs all over so it's not location dependent. I am getting ready to do a reinsall of OS in hopes it's that but I didn't know if anyone had any other suggestions?

Yup, I had the same thing. I'm TMO running global with no root. I rebooted my phone and corrected instantly. It's hadn't happened for a few days but I'm watching it. If it happens again I'll flash OS again.
I have rebooted, tried a new sim, factory reset, all the same. It also happens in another phone so it's clearly something on the provider side, not a hardware issue. I put another sim from a friend's phone in and it worked like normal. Now, it's the hassle of trying to get the provider to admit it's not my error.
