Verizon mobile hotspot vs tethering via foxfi

Does anyone know or heard of anyone getting busted by verizon for tetherig without paying for it? I just upgraded to a galaxy s3 and I tether to my nexus 7 via foxfi. I noticed that it uses up quite a bit of bandwidth as I use it at work to stream videos. I used about 22gb in 2 weeks with my phone and nexus combined. I didn't want to get busted so I signed up for their hotspot plan which I get for $24 due to my discount and its unlimited (thank god). But with their hotspot app my phone gets extremely hot and sucks the battery super fast while foxfi runs very cool and I noticed that I watched a episode and a half of breaking bad and it only went down from 87% down to like 82% that really impressed me. So I cancelled my hotspot plan and just use foxfi instead do you guys think verizon will come after me if I tether like around 10-20gb a month? I don't want to lose unlimited but I don't want to use their crappy hotspot app either. I could pay for the hotspot service and use foxfi anyways so they won't get me for not being subscribed to a hotspot plan but It seems pointless to pay them and not use their app when I can do it on my own for free. Any advice???

Verizon has no idea if you're tethering, no way to get caught. Use which ever app works best for you

That makes me feel so much better I really want to believe you but I'm kind of paranoid I might just pay them for the right to use it and use foxfi anyways lol do you also tether with them?

Well I wouldn't say they have no idea... if you go from no data usage to 100 GB in a month I believe they would start to question, however you are most likely pretty safe.
I just subscribed to it just to play it safe now I can do whatever I want with no worries only 24$ extra

Hello my fellow At&t and sgs4ers

So just today I made the switch to at&t from sprint. Very happy so far, minus what I had to put down (let's not go there)
But I got the 1gb plan and was wondering what everyone else has. cause I'm on the edge of deciding wheth 1gb was enough. I guess it depends on usage of course. But while I was on sprint I usually barely go over 1.2 gb.
I guess I just have to be extra careful. Do you guys have any thoughts or tips?

2gb just to be safe...
I am grandfathered into the unlimited plan...
It depends on your usage. My MIL had the 200MB plan and never had a problem.
My advice: Don't stream... anything. Use wifi as much as possible. Set your data usage alert so you know your usage before you go over.
I would say it depends on your previous phone. I just switched to AT&T to get my S4 as well (and regrettably but knowingly lost my unlimited plan) With my last device a Verizon HTC Incredible 2 (a 3g device on an unusualy slow Verizon connection), I would average 1.5GB a month 3-4. If I had to be away from WiFi.
I noticed with the GS4 being much faster and the faster LTE speeds, I can browse and pull data faster. If it weren't for my WiFi connections I'd be over 4GB already and I've had my S4 for 2 weeks now. I am sharing 4GB between 2 lines.
So I would definitly think about your previous phone and wireless speed in comparison to your S4.

Alright thanks guys.
I also kicked up juice defender for when my phone is off. Hopefully if it getd to close I'll be able to bump it up to the 3gb plan

I wouldn't use JD might use background data no? I stopped using JD or task killers long ago they make things worse. Like said above use WiFi as much as possible and set your mobile data reminder under data usage to like 800mb it will then warn you. Also pretty sure you can set a. Actual data limit in there too...

I have 2GB and never really even come close to 1GB. Only time I've gone over 1GB is if I watch netflix on data. Otherwise I do web browsing and listen to pandora a lot.

I thought they offered only a 1gb and 3gb. Not a 2gb?

Well esentislly it turns off any mobile or wireless connection when the screens off.

I know I own the app but stopped using it because it is worse for battery and data consumption vs being diligent and manually changing things. Or using NFC tags to turn things on/off

I have unlimited and usually use ~2 - 2.5 GB a month (I stream Plex and Music often). Some months have gotten over ~5GB... but as suggested use Wifi if your concern about data and do not stream.

GS4 data very sporadic

My s4 data is bad to kick off and back on. It has done had since I first got it. I have 3_g at home and it's very solid signal, I never lose signal in fact i keep 4-5 bars but data kicks in and out all of the time. My old phone was very solid never lost data signal ever. I have tried the 3 different radios and several ROMs but they all do the same thing? It doesn't show roming and it looks to be on sprint solid. I know I've read about losing data due to flashing but mine works fine then it doesn't work, off and on, off and on all of the time... Rebooting sometimes brings it back, switching radio off will sometimes too but sometimes I just have to walk away for 10-30 min and it'll pop back up... any ideas?

I will assume that you have updated PRL and profile. If not, do so. If that does not solve the issue, call Sprint to see if thry are working on towers in your area.
Yes I did update profile/prl as well. I have a second phone we keep in the house (as my house phone) but it keeps data signal just fine never drops either. I haven't called Sprint I may try that but I really think its buggy firmware

I called Sprint, wasted 10min of my life lol. But I set force cdma, we'll see how that goes. No lte here anyway.. in fact 2g some of the time.. gotta love sprints data (shoot me)
Sent from my SPH-L720 using xda app-developers app
Hope the problem works itself out. One last suggestion would be a factory reset (that is if you didnt wipe data through rom flashes). Doing so can potentially fix a lot of different isses....maybe this as well. Good luck

Force cdma seems to have fixed it. I get lte in town but I live and work outside of town. Guess it was always getting stuck between the two...

Your signal bars reflect your voice signal not data. Download this for real info on what your phone is doing

And check this site for LTE deployment info, you could be getting NV deployed in your area http://s4gru.com/index.php?/forum/39-markets/

Data usage

Has anyone else noticed a huge data usage from the note 3 or verizon in general?? I was on tmobile for the past couple of years and sometimes barely hit 3gb in a month. I recently switched back to verizon and within the first 15 days I've used almost 3gb of data. I'm not sure if it's Verizon or the phone causing this. All my apps have the background data disabled. Highest app using data is Facebook and Chrome. But that's maybe 100mb-300mb a week in the data usage. Anyone know what could be eating up my data?

Are you running a lot of speed tests? That could cause it. I haven't noticed a spike or anything unusual. I did use 40gig last month though. But that's normal.

Help with connection issues and 4g

Hey guys I've been having horrible 4g and connection issue for a while on all roms even stock. YouTube is horrible and most things won't load or they take forever. My wife's s4 and daughters note 2 are fine and when they have strong 4g I get 3g. Any ideas.

I have an SM-N900V as well. I was having fits with 4G and wifi. My phone is rooted via vroot. I thought that might be the issue. I did a factory reset and did not restore my apps. I found the phone is still rooted but my connections issues were gone. I started recovering my apps via new installations. I haven't recovered them all btw. I had a ****load I didn't need. I do need an ad blocker and the only one that really worked was ad vanish pro. AVP caused the wifi and 4G problems. I can load it but as soon as I start it and load an affected app, down goes the wifi. I hope this helps and leads to further experiments. We need an ad killer that doesn't screw up the connections. AVP worked fine on my S3 until 4.3 was pushed out.
