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'm having a rather specific and odd problem with my captivate(s), three of them to be exact. First I bought the phone, upgrading from an Iphone 3g, and the first day it was great, the second day, in the evening, I noticed that it started this strange rebooting loop. The phone doesn't seem to power off because I don't see the Galaxy S symbol it just merely goes black then comes back and searches for the network, finds it, then a few minutes later goes black again, returns, search for the network, and so on. It keeps doing that over and over again. So I tried a factory reset the next morning just to make sure it wasn't a problem with any apps installed. The same rebooting loop happened. So I called a rep and dropped by the ATT store and they said it might be the sim card, which was very very old (still said cingular) so we swapped it. Same problem the next day. Okay so I went and I replaced the whole phone. The second day with Captivate #2, this rebooting loop occurred again. The reps told me that I might have gotten two bad ones and to exchange it again, so I did. And yet again I have the same problem. So here are some quick facts about the problem that I have learned. Total time span has been about 3 weeks.
-The most important thing to know about this issue is that the only thing that prevents the phone from going into this rebooting loop is if I enable flight mode, no network connectivity. I believe wi-fi is okay but whenever I disconnect from ATT's network it stops rebooting.
-Occurs more frequently at night/evening (only happened once in the morning)
-Is not affected by signal strength, full bars, low bars.
-Is not affected by installed apps (Had done factory resets and with my third captivate all I did was put the sim card in and put it in my pocket)
-Is not affected by battery status, low or full
-Doesn't seem to matter if I have a lot of things running or nothing running, the loop starts when I'm browsing, texting, in a call, or just locked in my pocket.
-Does not seem to be affected by charging source (wall, car, laptop, ps3/xbox)
Another thing to note is that I had an Iphone 3G with an unlimited data plan before this. The Captivate upgrade was done on another line on my family plan then given to me with a 2gb data plan. After talking to multiple reps over the phone, they said they had the wrong IMEI number (I have no idea what that means) but that leads me to wonder what else is wrong and is it a problem with the Captivates or ATT itself?
I really need some feedback because I'm about to just give up on this phone, which is heartbreaking because I fell in love it. My 30 days is approaching and if I am indeed returning it, it'll have to be very soon. What do you guys think?
I got a used G1 almost a year ago, unlocked it so I could use it with AT&T and it had been working without any trouble until this past Sunday. I was running 1.6 for the longest time and never got around rooting it or installing mods. Suddenly, after I was on the phone for 2 hours, the G1 stopped receiving service. It was normal for the phone to drop service for a moment because of where I live, but after a couple seconds I usually get service again. I didn't.
I swapped out my SIM to an older phone and I was able to get service. So I figure it probably isn't a SIM card problem.
So I put the SIM back into the G1, browsed through the phone to see what was wrong and suddenly found that I had an "update all" button for the market. That's a feature only in 2.2, not in 1.6. I checked online to see if there were any updates to 1.6, but didn't find anything. I had no service, but a feature not in 1.6 on my phone.
After several hours of having no service, I decided to root my phone and install Cyanogen Mod 6. I thought maybe updating the phone might fix the problem. Hours later, I got CM6 up and running and used my brother's SIM to activate my Google account. It just so happened that when I was activating the phone, I had a small window of reception. After that, no service.
Monday I went to the AT&T store to see if they could help and my phone suddenly worked inside the store. I left it there for 15-30 minutes and service didn't drop, so I thought it was fixed. I left and just as I got home, my phone stopped working. So I drove back to the AT&T store to get a new SIM. Sad part is, my phone has service in the store. Again. I just don't get service anywhere else.
I got the new SIM, but I still didn't get service. My brother suggested that the antenna cable might be loose. So yesterday I went to pick up a screwdriver set that had the right size torx bits so I could open up the phone. The cables looked fine, but I pulled them out and plugged them back in. That didn't fix the problem. I still didn't have service.
Late last night, at the CS club at school, a guy with a G1 on T-Mobile put his SIM into my phone to see if it would work. After 5 minutes, my phone was able to connect. So I swapped my SIM back in, but no service. My G1 can see the networks. Right now, I can see AT&T under "Available Networks", but every time I try to connect, it says, "Unable to connect to this network at this time. Please try again later."
I'm using a spare phone right now, but I'd really love to have my G1 working again. Any help or suggestions would be greatly appreciated.
Same Problem
If it makes you feel any better.. 7 months later and I have the same issue. Been scouring the internet and XDA for hours without any resolution. Maybe AT&T is dumping IMEI #'s for devices not in their lineup? Older AT&T Sims seem to work though which is strange. Maybe this bump will get us some kind of response.
Hello,
I'm asking for some help to diagnose my call problems on UMTS.
First of all, three things happened recently, and let's assume that they happened roughly at the same time:
I dropped my Nexus 5 on concrete shattering the screen completely;
Google released Lollipop which some people believe has problems with 3G and LTE;
I'm using a rather old SIM card manually cut to fit micro-SIM dimensions.
About two days after receiving my Nexus 5 back from guys servicing it (new LCD screen) I had a telephone conversation that was disconnecting once every minute or two. There was no problem recalling though. The same day later I noticed that dialer app says "Emergency calls only" which was pretty weird. I was on Cyanogenmod 11, some recent nightly back then.
My first guess - revert to earlier nightly via TWRP. It didn't help - I was still on emergency calls only and nobody was able to call me. However, I could browse Internet without any problems on 3G.
Second guess - clean flash stock 5.0.1. It didn't help too, however calling went back on for some time (several minutes) before breaking back to "Emergency calls only".
Third guess - buy a starter SIM and check if it works. It did at first but stopped after an hour or so.
Fourth guess - bring the phone back to guys servicing the LCD to check antennas. I've left it for two days. It was opened and antennas checked. Everything was fine, not even a bent flex.
For all this time when on 3G/LTE data transmission worked flawlessly. I could download Google Maps, browse the Internet, whatever. It's just the very basic phone function that acts weird - as if I wasn't registered to a network. Everything seems to work fine on 2G, except for very rare disconnects (once per two, or three days).
So, considering it's pretty weird I'm seeking for help - could it be possible that after hitting concrete something broke down on the motherboard that results in such weird behavior? Or is, perhaps, my retro-SIM dying? Any ideas? Maybe flashing a well-tested radio ROM? Diagnostic apps?
My already 3 years old nexus 5 is working great, except that I have some troubles with my simcard. My phone isn't detacting it sometimes in the middle of the day, without any proper reason and then I have to restart my phone several times to make it work again. I already tried taking out the simcard and putting it back in but it isnt really helping. I also have the problem that my phone isn't really accessing the internet. Even though the 4G symbol is there I don't have a connection, the only thing that helps at these moments is to turn on and off the airplane mode, that way I can access the internet for a quick time, enough to refresh a web page or send some whatsapp messages. I already tried to tape that area where the simcard is placed to make it more stable, without any success.
Does anyone have an idea what to do? I don't really want to buy a new phone since the n5 is working great for me.
Hey,
had exactly the same with my N5. Not sure if it's related to a securtity update or not. I was not able to get it work again. Probably it's getting worse for you with time. There are some threads around xda dealing with this problem, but - at least for me - there no solution yet.
regards
Same problem here since a few weeks.
If you have updated the radio to the last version, and if you have already tried and got the same issue with another sim card, then it may be a motherboard issue.
this is the phone from the https://forum.xda-developers.com/galaxy-j7/help/4g-lte-sm-j700h-t3543821 thread. I had become used to this phone not being 4gLTE supported.
But over the last month, almost all data usage has become so excruciatingly slow that data has in effect stopped. Most pages seem to stop at about the 15% mark. Waze wont pick up any signal at all and even CoPilot gives arcane errors when it is accessing data as opposed to GPS.
Samsung sent me to their 837 Washington repair location where on an absolutely minimal 'inspection' the bloke there identified that I have an international phone which he announced will not work and cannot "for hardware reasons" be made to work in the US. He said it has the wrong radio to work in the US. (dont I remember updating the radio as a software feature on my Cingular 8525 reasonably regularly? This is j700hxxu3bqc2)
I wondered whether this hardware impossibility could be the case if it had been working for 9-10 months, if a bit slowly. I said the problem had only started over the last month. He said T-Mobile had been changing things within all their transmission towers about a month ago. After which my SIM1 is now admittedly in constant "Roaming" mode on the home screen, although SIM card status shows tmobile in service, EDGE, not roaming (and mobile network disconnected with a signal strength of -87db, 13asu whatever that contradictory info means???).
Can I do anything about any of this please? Could I achieve anything by rooting and flashing?
None of this has anything to do with Smart Manager being in what it calls ultra data saving mode does it?
