MetroPCS blocking data on flashed phones

I can confirm that MetroPCS is blocking flashed phones from using their 3G data network as of today, November 5, 2012. I had my Epic 4G slider flashed to Metro around 9 months ago. 3G worked up until today. I let my service lapse (for all of 12 hours) and after I paid to have it reconnected, my 3G no longer worked properly. It is actually still connected to the Metro 3G network and 3G shows in the top bar, but the only webpage accessible is a page titled "metropcs_tethering_message" which states:
"Per the Terms and Conditions of Service, Tethering / Mobile Hotspot is not currently supported. Please visit --- for terms and conditions of use."
To be clear, I am not tethering or using the phone as a hotspot... just trying to surf with the phone itself. The days of flashing to MetroPCS and using data seem to be over. I wonder if it has anything to do with their impending merge with T-Mobile?
Time for me to find another inexpensive call/text/data solution.
[email protected] MetroPCS!

Its been like that ever since they blocked tethering.. some cities were opted out from 3g before tethering was blocked. Requesting the desktop version of a site on a metro phone makes that same message appear. It's likely to be an easy workaround but worth the trouble? Certainly not. I suggest you take a look at the virgin mobile guide in my sig.

Well, an interesting development...
After buying a new (to me) GSM sim-based phone (LG Optimus G2X) and signing up with SimpleMobile, I was prepping my Epic 4G slider for sale and re-flashed my rom to the same custom rom I had been using for many months (ThunderHawk EG22 with Nubernel 2.6.35.7 kernel). After I did this, my data connection started working again. Might not stick, but it's been on for a couple hours now.
Now, this wasn't some glitch or bug in my system that caused the data connection to stop working as stated in my original post. I confirmed with MetroPCS that they were actively blocking my data connection, so it wasn't something wrong with my phone. However, after reflashing the rom, it works again! I'm still selling the phone though and moving on from GhettoPCS.
I'm posting this so anyone else who's had their data connection blocked can try reflashing their rom (even the same rom, apparently) to try to get their data connection back.
But once again, [email protected] MetroPCS for blocking flashed phones! Why do they care where we get our hardware to use on their shhitty service?

That may be the placebo effect, many outdated Epic Roms improperly displayed 3g icon when it was in fact 1x.. you should do a speedtest and verify its Evdo Rev A or Evdo RevB and not 1x..

No 3g or wifi

Good morning,
I've been reading the forums for a while for solutions and tips but I am stumped on this one.
So I had stock Epic 4g (SPH-D700) on the Sprint network that was rooted and running CM 10.1 just fine. My USB connection broke so I bought a new motherboard so that I could switch to Cleartalk wireless, which required a connection for them to flash. They flashed the phone and while in stock, 3g data worked fine as well as phone calls and texting. Even stock though, with new motherboard, wifi did not work. It wouldn't even turn on to search for a connection. After rooting and flashing CM 10.1 while on the new Cleartalk network, 3g data now does not work and it gives me this error "unable to resolve host get.cm no address associated with hostname." Wifi still behaves the same. Calls and texts still work but I currently don't have any way to connect to the internet via 3g or wifi. Please help! I don't want to go back to stock just for connection.
Thank you!

Sounds like 2 issues here.
1. You probably forgot to connect the wifi antenna when you swapped motherboards.
2. You don't have your APNs configured for Cricket after flashing CM10.1.

1. I will double check this as soon as I can.
2. Any idea how I can go about configuring the APNs? I saw a solution where I backup the APN's with an app while in stock then restore once CM 10.1 is flashed. Will this work for me?

****, no it's not lol. Sorry, I misread. There isn't a ClearTalk thread in our dev forum that I'm aware of. You may want to search the entire XDA site and even Google for that carrier's APN info.

No problem. I will try some things and update this thread with the progress. Thanks again!

So it isn't the hardware connection for the wifi problem. I checked everything and it still didn't work. I even reinstalled the old motherboard to make sure I had all connections right and the wifi worked fine. I just discovered the Bluetooth also doesn't work.
I haven't tried repairing the APN yet, I will update after I try.

Using "APN Backup and Restore" did not work. The app runs and says it is successful but doesn't actually restore the APN's. Or it does and that isn't the problem.

VPN issues?

I'm not so sure its just my VPN provider anymore. I've tried a few different apps and I get the same issues.
I'm currently with Private Internet Access (PIA) and I've tried both their app and OpenVPN and sometimes it will connect on LTE but I get no active data transfer.
I have reason to believe its because g3 doesn't do ipv4 anymore? But that doesn't make much sense as OpenVPN works over ipv6 supposedly. Is this an issue with my provider or the g3? I can't seem to figure it out. Anybody else having VPN issues? Please post results.
I am aware I can use native VPN feature but I don't like that I can't use a knock code for credentials.

This thread might be of help for you in regards to getting VPN to work: T-Mobile D851 IPV4 Support
The two main posters in there are trying to get IPV4 to work on the G3, as one of them, The Pagel, was trying to get it to work for their own VPN apps.

The issue is probably that you are getting a private IPv4 address from the provider, as well as a public IPv6 address (LTE areas only).
Most companies are still running VPNs on IPv4, and some VPNs won't play well with certain NAT implementations, which is used when you have a private IP address.
When you disable 4G and eHRPD, you will start getting a public IPv4 address again.
As you may have heard, we are running out of IPv4 addresses, and provider using NAT and Private IP addresses is a work around until more people deploy IPv6. Once your company deploys a VPN on IPv6, things should improve. However, this could take a while as this is a major transition and in some cases will require software/firmware updates on network equipment. Also, some very old operating systems don't always support IPv6, so all of that has to be retired as well.

Anyone know of a VPN service that runs IPv6 that would work on android? PIA doesn't work at all

I ran that patch from the other post, and no luck. Not a single VPN connection works on this phone. I am debating if I should take it back, as a VPN is a necessity to me

Did you mess around with your vpn settings at all maybe you should uninstall then re install? Pia is working fine for me with ipv4 in fact I am posting right now from my g3 on the vpn.

No script just make sure your on ipv4 not ipv4/ipv6 I think the script your referring to is for tether unless there is a script I haven't seen yet.

Anything one flashes I consider a script. Wrong terminology I suppose. Also didn't notice you were posting in my thread....hai!
I take it you're mod works fine now?
I've thought of flashing it as I now live in an area where 3g and hspa could come it handy as I get either LTE, edge, or nothing now, mainly nothing.
I'm doing a bit of traveling atm so I can't peruse the pages, but how's it coming along? I could care less about native tether, there's apps to do it. As long as i t doesnt mess up my xposed tweaks I'm 3 seconds from flashing it....

Yeah native tether still doesn't work but everything else does. A few people have had problems but not many. I would suggest you make a backup before you do it because xposed is kind of a jealous lover and hates when you eye other modifications. But on the other hand it really depends on what xposed modules your using.

Just g3 tweaks. I wasn't sure if I could use normal xposed tweaks. I'll have to make a new backup with my xposed and I'll give it a shot. PIA working on WiFi still with the mod?

Probably not but I will check
*edit
Wait still? Does it work now? Haven't tried to find out.

I think it's something with LG's android build. When i had my Moto X I could use PIA on LTE. I did not check to see if it kicked itself to IPv4 but that seems to be the problem. It works if you have the EPC T-Mobile APN set to IPv4 and connect through HSPA+.

ipv4 is definitely locked down for fast on this tmobile version but it is luckily a easy work around if you don't mind loosing built in tether. I have confidence that built in tether will be fixed for that mod soon but I am currently using my phone tinkering time (limited atm) on a korean port that wont require any modifications. Before I stop caring about tmobile builds ill fix it. Something I am sure a lot of people might find interesting is after my first boot on the korean port it is looking like I might be able to bring voice over lte to our phone before it officially happens.

Unsure if related to the mod, but attempting to access tmo account via tmo app yields a server error
Since applying the mod

Radio problems.

So, i'm in the UK with my nice shiny OP3 (on Three UK) - I am rooted with twrp, but same applies on stock.
The radio in this phone seems to prefer H+/3G to 4G, even though where i live, i have full bars on both. My nexus 5 always prefered 4G, and the OP3 is set to prefer 4G but 90% of the time drops to 3G/H+
Another interesting thing, if i use the testing menu to force LTE only, even if it's on 4G already, completely stops any signal getting through for a number of minutes until it decides to connect sometime later. I have full LTE signal in my room too.
Is this a radio problem that could be solved in the future with a software update? not seen anyone else with this issue!
FYI, when it is on 4G, it's super fast and stays connected until a reboot, where the whole process starts again

APN Is exactly the same as my nexus 5, and i even added a new one. Same deal.
I'm an IT Professional, just not a developer. i've done everything i can think of. 4G does work, but only when it wants to. My phone is also registered with my carrier correctly.

Bump on this anyone?

I am having a similar problem I guess. I have the dual sims installed and one sim randomly shows no range. Further, the network preference is not the way it is supposed to be - Chose it as 4G and if 4G is not detected it falls back to 2G.

I'm having a problem where the phone catches 4G+ "carrier aggregation" and it'll jump from to 4g+ to 4g and back to 4g+ really fast like almost flashing . And speed test are showing low numbers. T-Mobile USA.

Same here. Sometimes it just locked to 3g/h+ in a strong LTE area for no reason. I'm on stock oos with one sim and 1 apn. Sometimes I need to reboot the phone to get LTE back.

I first put my sim into slot 1 when I first got the device, I was having the exact same issue. I found that the data priority sim, or if you only have one sim needs to be in sim slot 2.

Yes exactly. And even then it doesn't show up straight away despite 3/4 and usually full signal. Sometimes just putting it into standby mode and leaving it 20mins can sort it... Until I get another call lol. Wondering if it's just a software or firmware issue that could be patched. Lte is fine it's just never preferred despite the options being set

APN is not the universal response. Here he faces a problem of inaccurate network type choice, APN is only to have acces to internet through the provider's proxies. It's a radio problem clearly, the baseband is probably to be corrected by OnePlus.
It's really a strange thing to see those network type issues, MMS issues are still present after all those years.

This is what I thought. It's probably an easy fix for oneplus or rom developers. Custom radios are nothing new. Let's hope so anyway!

This is happening to me as well. I'm on three in a strong 4G area but it always prefers 3G it's so annoying hope it gets fixed soon.

i tested op3 with 3 different carriers
on two of them - lte no problem, instant connect...
on third sim - slow connection, frequent out of range. almost no lte.
tested third sim on iphone - instant lte connect, no problem.
seems like a incompatibility with an selected cellular operators.

Could be but I'm doubting it. OP3 Has full support at least for my carrier on both bands they use (3 & 20).. Never know, the devs here will figure it out if oneplus don't

Same issue here, have never got it to say 'LTE' for me since I got the phone, best it does is 4G whilst my Galaxy S5 would happily pickup LTE. Just wondering what UK users have there preferred network type set to? Mine is on GSM/WCDMA/LTE I assume that is right as that is what it went to itself and have tried LTE or LTE/WCDMA too.

slow mobile data connection

After I updated to 5.1.5 mobile data has been either really slow or not working at all. It's not my ISP as my whole family use the same and don't face the this problem. Does anyone know a fix to this?
Update: If found the problem. All apps where set to data usage disabled automatically after the update.

You mean 5.1.5? Anyway I'm on the OpenBeta17 and I have the same problem in 4G (Vodafone, Italy).
