Tethering and the Spring SGIII - Sprint Samsung Galaxy S III

Ive read a few posts here after doing some searching and im a little confused as to how it works. is it possible to tether on a completely stock/unrooted SGIII on through sprints network? ive read a post stating something along the lines of it voiding a warranty, some other people saying it will immediately kick you off of 3g, and others stating you need to download a 3rd part app like foxfi for it to work. can someone shed some light on me as to tether with sprint's network and the SGIII? im looking to switch to sprint and pick up this phone, but tethering is important to me. any help would be greatly appreciated.

If you want to tether on stock, unrooted firmware, you'll need to use a 3rd party app, like foxfi, etc. Rooting voids your warranty, but the gains of rooting are worth it

Cannot receive SMS from AT&T after root

Hello all!
I've had this issue since I rooted my phone (with NAND unlock using Toast's method) back in the beginning of June. I noticed this issue IMMEDIATELY after rooting since my girlfriend is on AT&T. Recipients on AT&T can receive my SMS just fine, but I cannot receive theirs (I have tested multiple phones on their network)! Other carriers seem to work just fine as I have tested most of the popular ones although haven't tried T-mobile, could it be a "my phone versus GSM" issue?
I have wiped and factory reset my phone numerous times, used multiple roms including the rooted stock 1.32-1.47, OMJ's 1.4-1.7, and currently am on Baked Snack 9.6. Out of an act of desperation, I accepted the 1.47 OTA update before root with no avail. After all of this I have noticed one thing staying the same... The PRI Version 1.34. I know there is no current way to update this back to the stock 1.40, and too be honest am not really sure if this could even be the underlying cause of this issue because what does roaming have to do with receiving SMS on my home network? I've had multiple people tell me that they have had no such issues, and searching the boards shows me that this is definitely an isolated issue.
If anyone has any advice, information, or even has this issue as well please let me know! Any help will be greatly appreciated!
Call Sprint, sounds like a network issue, not a phone one.

Well, after several phone calls and tickets later, I have now found out that the AT&T messages aren't even hitting Sprint's gateway (the front door of data). It's odd because the tech rep is able to see my messages out, but not able to see the ones sent back. This leads me to believe that it is in fact a network issue, and has absolutely nothing to do with my phone. He clarified that even if my phone was broken he would still be able to see the messages at the gateway, but they aren't even getting there. There is nothing more that Sprint can do because they can't reference something that doesn't show in their systems; so I'm being forced to call AT&T... I have already gotten the run around from both sides stating, "well it's definitely an issue on their network".
I'm not really sure what else to do, it just seems so strange that the very same day I rooted my phone, I stopped being able to receive their messages. The only thing left for me to do is try and get a replacement phone? and if I do that, do I root my phone again and risk being burdened by this issue again? I know one thing's for sure, after having a rooted phone for almost a month and a half, there's no way I'm staying stock!
Getting a new phone won't help you, it's definitely AT&T's network, or whoever owns the bandwidth connecting their (AT&T's and Sprint's) networks. Simple as that.

Thank you drmacinyasha on your quick replies!
I'm hoping to get my girlfriend's account information soon so AT&T will actually help me; I'm just worried that they will say the same thing Sprint has told me. I know it's as "simple as that" to state where the problem obviously lies, but I'm not sure how simple it will be to get a hold of someone who will actually be able to fix it.
My girlfriend is able to send SMS to other people on Sprint just fine, so I'm confused by the fact that this has only happened to my number.

[Q] Can the CDMA Xperia Play be used without any service? (wifi only)

Hi, new here. Sorry if this is a strange question.. I couldn't find any other threads related to this.
So I really just want to know if I can use this phone similar to an iPod Touch. Strictly over a wifi connection and no cellular service plan. I already have a phone paid through work, so I'm not interested in getting a phone plan. Just plan on using it for playing ROMs and just using it like an Android tablet over wifi.
Any help would be appreciated. I don't want to find out the hard way through an expensive ebay purchase.
Thanks!
- Jon
I'm pretty sure all android devices can be used apart from an actual plan, if you just use wifi.
Thanks!
Thanks for the fast response. I was just worried that I might run into complications without a service plan. Of course I'd be rooting it anyways.
Thanks again!

[Q] Questions about unlocking HTC One M8, using unlimited data for mobile hotspot

Hello folks, Ive lurked here for a while and gotten great info and am hoping to get some help here. I apologize if some of what Im asking is obvious to you folks but it isnt to me so here I am. I tried HoFo but got no help there.
Ive been using factory unlocked Sony Xperias for a while (Z, ZL, Z Ultra)so never had this issue before, but I have an HTC One M8 coming and unfortunately its ATT branded, though I bought it from a private seller and not ATT themselves. Im also grandfathered into unlimited data for many years now, and with my Sonys can turn on mobile hotspot anytime and use my data with ATT none the wiser. Now Im assuming since I was dumb enough to buy an ATT phone, I will be told to contact ATT once I pop in my SIM and try to turn on mobile hotspot, is this correct? If so, will unlocking the phone resolve this issue? As of now ATT has no idea Ive bought this phone, nor did they ever even recognize my Sonys because they never sold them, but since this is an ATT M8, Im assuming theyll know immediately what Im using, identify my plan and lock me out. Im hoping I can get around that.
I also imagine since its an ATT phone it will have all sorts of abilities locked out and a lot of fluff added in. How can I get the features unlocked? Is there anyway to buy a carrier branded phone and get it to be similar to one that was bought factory unlocked from the beginning and never branded?
Any help and advice would be appreciated and TIA
Ok, if I asked too much stuff there that was obvious to you but not me, can someone just please tell me if unlocking the bootloader will at least unlock the mobile hotspot function for me so I can turn it on?
Well, just unlocked, rooted, s-off and twrpd my first phone. What a b*tch, lol! But I had to learn one of these days. Sadly, still cant get the native or any other mobile hotspot app to work though. I saw a thread about a VZW M8 hack but still cant seem to find anything for this ATT thing. No one even willing to talk to me?

You can try wiFi Tether Router. Its in the play market but you have to pay $2.50 for it. Has worked for me. I don't think this app can be dectected by the carriers like ATT because it does't use the native hotspot of the phone.
Youll have to flash a custom rom that has this feature [email protected] and is debloated,xarrier build will block it and tell you to conract them.....
This is not going to help you at all, but I pay the extra $30 per month. I use up to 50GB of data each month tethering, and I want to make sure the my carrier doesn't block me.
So now that I've done my service by telling you to do the right thing, you use to be able to go in using SQLLite and turn off the checker. For VZW it was around line 149 - 160. Can't remember. I would think you could do that for AT&T. Maybe someone knows? Or maybe AT&T doesn't work like that any more, of maybe KK doesn't work like that any more.

[Q] Can't tehter On My New T-Mobile LG G3

Hey guys, so i have the G3, tmobile, but I'm using a simple mobile service.
Problem is, my G3 Died and LG just repaired it, bought a BLU phone to use temporarily and it work fine tethering. And my Old G2 tether fine as well, so i don't think its service issue.
But before my G3 died and after it was fixed, I've never been able to get the hotspot to work. When my tablet connects to it, the WiFi icon always have an exclamation mark on it.
Any idea why this is happening ? I really need the WiFi at work. Can't tether it to my laptop either, will say "Unlimited connection".
Any help will be appreciated.
And my data plan is work, i have 10GB of high speed month, right now i've only used about 200mb of that, so its not because i don't have data plan.
Thanks

sounds like your wifi was damaged, id send that backand warranty that fast.
you think? or i need to root it in other to use my hotspot with simple mobile, since its a tmobile phone and i don't have tmobile service, perhaps that's why its blocked?

What app are you trying to root with? If you are trying to use t-mobile's "mobile hotspot"app or the Settings/Tethering & Networks/Mobile Hotspot... No, it is not going to work for you without a t-mobile data plan.
You might be able to find an app that allows tethering, but I think you'll need to be rooted.
I know that MetroPCS is a *itch to get free tethering with.
I'm afraid of rooting this device lol, don't wanna brick it, it died on me once, out of the blue, that's why i sent it in for repairs.
Yes, as you know, its a tmobile phone, but my service is simple mobile, while it was being repaired by LG, i bought a BLU phone for temporary use, and it tethers fine without root. And my old G2 tethers fine without root either, so I'm surprised this G3 is making that hard. So i can tether with other phones, even though its simple mobile service on a tmobile phones, so I'm thinking the G3 might be the one with the problem. And if I'm to root, you have any idea the best thread for that? Thanks for your time.

V35 + Cricket = no paid hotspot. WTF? help...

For years I have used a Leeco with a custom ROM as a hotspot for the Android head unit in my car. Last month, I got a warning about hotspot use and decided to go legit. The hotspot data got funky after the warning.
->I bought an LG V35 direct from Cricket, carrier unlocked
->I upgraded 5 family lines to the "Cricket More" plan that includes 15GB of hotspot data
But Cricket blocks all except a short list of phones from hotspot use even with a paid plan. I spent about an hour on the phone and they basically offered me nothing except to return the phone. No BYOD phones will work as a hotspot either except for iPhones.
What can I do? Has anyone else run into this? The custom ROM Leeco basically didn't work after the warning. Is anyone successfully using a V35 with a custom ROM as a hotspot?
Thanks for any help.
10/6/2019 Resolution for anyone else with a similar Problem:
1. it is difficult/impossible to bootloader unlock and root a LG V35. But that's not apparently the issue here.
2. Cricket only supports wifi hotspot on a short list of phones and all else including BYOD rooted/custom ROM devices are throttled to the point of uselessness even with a paid hotspot plan.
3. PDAnet works well but didn't work for my Android car headunit even after every known update.
4. I am using EasyConnect, a point-to-point screen mirroring app over USB, on the head unit and its OK. Not great but good enough to not trash Cricket and look for a new carrier.
Thanks!
Since no one else has responded, I'll make an attempt. You are going down a lot of paths without gathering any info in advance. The v35 cannot be bootloader unlocked without specialized tools. Even if you bootloader unlock, there is limited developer support. TWRP has not been ported to the v35 and there are no custom roms. Hopefully this situation will change, but the prospects are dimming as time goes by.
You still MIGHT be able to get hotspot working. I say might because I am not familiar with Cricket. Many carrier's phones check for a tethering subscription before allowing the hotspot to be turned on. The rom on the phone communicates with the carrier to make the check. That MAY be the issue you are facing since Cricket is an arm of AT&T. If so, you can get around it by cross-flashing to the open market / Google Fi rom which won't do a subscription check. I did that with my AT&T branded v35. It works great on StraightTalk. Browse around in the threads in the v35 forums and you will find information about how to cross-flash.
Now back to the MIGHT part. Some carriers, Verizon for example, can detect tethering. They throttle hotspot speeds for Unlimited plans. Presumably they could just block hotspot traffic. I have tried everything to get around throttling to no avail.
I might be able to help here. I have a rooted essential phone on the unlimited data + hotspot Cricket plan. I am able to activate hotspot but it is severely throttled (128k by the looks of it). No fixes, not even fixes that use root, has changed this.
The only thing I have gotten to work is pdanet app ($8 in playstore, after 30 days). With it I am able to connect my laptop/tablets to my data plan, all while hiding the usage from Cricket. I am not sure if this will work with your head unit or if it's viable since you kind of got to jump through some hoops to get the stuff working but just thought I would chime in here.

Thanks, there seems to be 2 things going on. 1st is the tether provisioning check. One can turn the provisioning check off (most custom ROMs have done this and it was what I did with my Leeco); or you can pay the carrier. For my v35 I paid the carrier and it still didn't work since there is some 2nd network check that isn't visible to me.. What runderekrun describes is exactly what happened to me.

Thanks, that is helpful. For me, I went years with no trouble and then got a warning text followed by the throttling. It was very, very slow.
I just tried PDAnet+ and it worked! Hurray! seems to need the app to act as a passthrough but I can live with that. I have not tried it on the head unit yet but it's fundamentally just a big Android tablet and PDAnet just worked on my tablet that is actually a tablet. Thanks!

PDAnet+ worked my S3 tablet and Windows laptop. But did *not* operate for my Android head unit. Any tips for figuring it out?
