[Q] Evo on MetroPCS- says ROAMING?

I'm trying to finish getting an evo to metropcs for a friend. I did everything you need to do to get to the point of "activation". I put a newer Metro prl on the phone that works here in the ny area... but when i try to activate it or even call I get redirected to a verizon operator. The signal bar says I'm roaming and where it should say "MetroPCS" on the lockscreen its says"Analog B". Will an evo on metro pcs even work in the NY area? If not I just wasted a huge amount of time

Did you get the esn registered to metropcs? must I add must be considered coorperate store

go to settings>wireless settings>mobile networks>system select> change it to home only then also....make sure you still have the MetroPCS prl installed...dial *228 and make sure it says "hello hello hello metropcs" and if it does u might as well update the roaming list...say update roaming list after it says it

I didnt get my esn registered with metropcs because I assumed it was already registered.. Should I go ahead and try to do that, and if I do do you think they will they even allow me to?

If I'm correct the instructions you've provided will only allow me to connect to the towers that my PRL tells me too. Which makes sense since having it set to "automatic" will allow to roam and connect to a verizon tower, due to a roaming agreement between metro and verizon. Thanks for that hint. So I just did as instructed and It says I have no service (the little "x" by the bars.) oh I also followed these steps to re-start a hands free activation:
Steps:
1. Dial ##3282#
2. Enter Edit Mode
3. Enter your MSL
4. Select Data Profile
5. Menu
6. Restore
7. Let Phone Reboot, and Wait and the Hands Free Activation will Start.
and of course It didn't work because i have no service

Damn...I'm at a loss here...
Yep...get the esn set up with metro...

Damn guess I better, thanks for the input. I appreciate it

I realized that the esn on this evo is already added to the metro network.. due to some unmentionable modifications. I simply cant get service to activate the phone..

[UPDATE: 4/2/12] PRL Information Thread

Before I go into the full details of the project, let's go over what a PRL is, what it does, and why it matters to you.
What Really is a PRL?
"The Preferred Roaming List (PRL) is a database residing in a wireless (primarily CDMA) device, such as a cellphone, that contains information used during the system selection and acquisition process. In the case of R-UIM-based CDMA devices, the PRL resides on the R-UIM. The PRL indicates which bands, sub bands and service provider identifiers will be scanned and in what priority order. Without a PRL, the device may not be able to roam, i.e. obtain service outside of the home area. There may be cases where missing or corrupt PRL's can lead to a customer not having service at all.
On many networks, regularly updating the PRL is advised if the subscriber uses the device outside the home area frequently, particularly if they do so in multiple different areas. This allows the phone to choose the best roaming carriers, particularly "roaming partners" with whom the home carrier has a cost-saving roaming agreement, rather than using non-affiliated carriers. PRL files can also be used to identify home networks along with roaming partners, thus making the PRL an actual list that determines the total coverage of the subscriber, both home and roaming coverage."
Source: Wikipedia
TLDR: The PRL tells a device what towers to connect to, which frequency to search on, and in what order to connect to them. This includes "on" and "off" network towers. PRLs do not effect 4G WiMax performance.
Why Should I Care?
The PRL directly effects the coverage you receive and the data speed performance of your device. Ensuring you have the latest PRL is critical to maintaining the best signal your device will get. However, there are a few "special" PRLs we can use in order to gain access to hidden features, such as 3G data roaming.
So What is This About?
I'm glad you asked. I've been working on this for a few months now and I'm now ready to go public in order to gain more statistical data from my fellow peers. I have a collection of PRLs that I have rigorously tested to see which ones give me the best performance. This isn't enough. I need real world testing for as many members as I can get.
While I can't give the full details of my project away yet, let me assure you it will benefit everyone on Sprint. Phase 1 of my project has already started and here is how you can contribute:
https://docs.google.com/spreadsheet/ccc?key=0ArqBGjrbNosddGR3OURoNnJLdTlTaEo1RmVEYjdVNlE
The above document is open to everyone and can be edited by everyone. This spreadsheet will be used to compile data from everyone's usage of the PRLs available to us. Check the bottom of the file for sheet of each individual PRL. Each one has it's own sheet. Just add your data for which ever PRL you are testing.
The tool accepted for measuring data speed is Speedtest.net. They are the industries leader in speed testing, and it is a very reliable application.
If the PRL you are testing isn't there, I have included a template sheet so you can make your own sheet. Please stick to the format and be honest. This project is for everyone to benefit from, so don't ruin it for anyone. Also be sure you are adding your raw data to the correct PRL sheet. Little mistake like that can skew the data. Please test "Home" and "Roam" equally, I am trying to obtain the best performing PRL overall. I want to repeat that 4G WiMax is not effected by PRL, so do not include 4G in your testing.
Be impartial, be true, be consistent, and most of all be precise. If you notice something is wrong, fix it. You can chat inside the document. Just check the top right hand side for the people viewing the document. I will check this document often and update it regularly.
I have included the primary PRLs for testing in the 2nd post, and instructions how to manually update your PRL from a PC in the 3rd post. If you have any questions, please feel free to ask away.

What are your opinions on 12117? I am interested in this one.

So far it hasn't performed like I expected. I believe this is due to our devices not being Network Vision ready. Originally it was reported and displayed that it was tested for the 800 MHz band, but I guess that was a lie. I do not think the 800 MHz band can be disabled by software. This makes sense since we have the regular PRL's like all the other devices.
So far 60683 performs the best on network. If you roam a lot, the 11115 seems to be the way to go, that way you can flip between roaming and home network with Roam Control.

Yes way out here in the country 1115 has worked best for me. Thanks.

Feel free to test the 12117 though! You never know what you may get in performance. Maybe it really does work and our device can pick up the 800 MHz frequency? Maybe during the time of testing 12117 didn't perform like it should have due to variables.
Like I said, I have multiple tests I still need to run, then I can move on to phase 2.

Maybe you are not in an area with network vision enabled yet?

I'm really interested in trying out the 11115 PRL. I'll let you know how it goes.

Love that you wrote it on a boogieboard. Thing's really useful.

Been running 11115 for awhile. Definitely get best of both worlds

Does 9999 has Verizon 3G or only Verizon 1x?

Running 11115 PRL here. I get exceptional roaming data rates, and very good home network data rates. Coupled with Roam Control for network access at work, 11115 PRL is best for me.
Thanks Korey for all your work.

Excel is more practical...

Wouldn't it make more sense to do the tests at morning/afternoon/night on separate days, then take the average from there? I think that would be a more well rounded test.

11115 has been the best for me by far. Alot of the places I go I end up roaming. Paired with Roam Control I can switch it over to roaming and get Data when I need it. I don't run it like that all the time but when I do force it so roam I get nice 3G speeds.

I've tested 11115 multiple times with latest version of Roam Control, in Northern New Jersey. I only get 1x Verizon data speeds, no matter what, including the typical long latencies (~900ms).
With 9999 I get robust 3G Verizon data, but doesn't roam back onto Sprint when there is poor Verizon coverage.
Ideal would be something akin to 9999 but with roaming back onto Sprint network when needed.

I have been using the 01337 Hacked Verizon PRL for a long time now and it's performed great.

what is unique about this one? Sprint and data roaming on Verizon?

Do I have to force roam or will it do it automatically?

*Sprint Galaxy Nexus*
Hey guys, I'm new to this phone, so I have 4.2 AOKP flashed. My concern is the roaming.. I tried to force roam with Roam Control that didn't seem to hold.
So I used the CDMA Tools baked into the AOKP rom and flashed the Verizon 0001 PRL and the phone roamed just fine.
My question is: will this phone NOT automatically roam using a standard PRL?, I'm not in a poor service area at the moment to test.
Sorry if this has been asked 19,000 times, I'm worried that I'll have to set the roaming manually every time.
Thanks!

[FIX] FreedomPop APN Fix

FreedomPop is a MVNO on the Sprint network, and they offer a free (!) service with 500 MB of data, 200 MB of voice, and 500 texts. The caveat is that it's data only, and voice operates on VoIP. But by adding "friends" you can get an additional 500 MB of data for free, so it really isn't a bad deal.
Various APN fixes have been around for those who are operating with custom ROMs, but I've found all of them are slightly different and none of them allow access to all services for data (1G, 3G, LTE) all of the time.
I've tried to remedy this as best as I can. Here is my APN fix, which is really a mod of the existing one. It works great on my Galaxy S3, should be device agnostic.
Please try it out and let me know if you find improvement.

Hey there. I have an old Evo 4G i wanted to try this on... i can't get the google drive to come up. anyway you can send me a PM with a link? Thanks! Or repost a link . Thanks!!!
**** looks like it was just a hickup... downloaded and trying it now. =-)

Let me know. I've used it on a ZTE, and LG G2 with improvements over the other one floating around.

The only way to get Samsung activation menus is on stock firmware. On CyanogenMod you need to flash the son fix along with the ROM. Flash ROM, gapps, and apn fix. Then boot up fully, setup on wifi if you can, then back to recovery and dirty flash just the ROM. Dirty flash means no wipes or anything, just flash

Sprint Moto Z2 Force on Ting (WiFi Calling Missing)

I recently purchased a new Sprint Z2 Force and activated it on Ting (it has only ever been on Ting and never on Sprint directly). Both Sprint and Ting support WiFi calling on this phone, but WiFi calling is not listed under the WiFi settings or in the Call settings of the dialer. However if I search in the settings for WiFi calling, I can see a WiFi Calling Settings in the App Info section, yet there is no way to turn it on or open those settings. I have updated the profile multiple times and also did a factory reset.
Am I missing something or is there something missing in the software since it never got activated directly on Sprint?
Any help/suggestions would be appreciated.

I do the custom rom thing and i sort of remember it just being there however, if you have not already checked "Mobile Networks" - under main phone settings, select "Network & Internet" once there, select "Mobile Network" - you'll see your carrier stuff/APN there I believe if you select "enhanced 4G LTE Mode" (you may have to make LTE you're preferred network mode in order to enable and/or display that option, again this was already there on mine. But see if that opened up any new menu items elsewhere i.e. back in the dialer app settings under "calls".
Did your phone come with a sprint SIM? Do you have the other carrier bloatware on there like Sprint ID? I know what you meant earlier about a possible software bypass, but all of that stuff is deff on the phone somewhere like you observed in App info, it may just be a matter of popping in a sprint SIM card to unleash it..

I continued to look into this for you. Sprint's name for Wifi calling is, well was -"Calling Plus". I found this article that advises one of the recent update removed the feature;
https://community.sprint.com/t5/Buz...alling-PLUS-Service-Decommission/ba-p/1017775
Since you got the sprint version you still have lots of software modification options. I also have sprint z2 foce, but I get better coverage on a GSM netwrok so my device is half sprint\half tmobile and I can deff say the wifi calling works. There's tons of information on here I can always help direct ya, but at least you're not crazy it WAS there.
lastly just to be sure, this has to be done prior,
"Log into your Ting account online and go to Device settings. Find the device you want to enable Wi-Fi calling for and click the edit icon in the Minutes section."

Thank you for all the info so far! Here are some answers and additional info:
My phone did come with a Sprint Sim in it and that is the one I am using. Also there is not any of the Sprint Bloatware on the phone. If I search "Sprint" in my settings area, there is a My Sprint Launcher that is listed as Disabled and there seems to be no way to enable it, which is similar to the WiFi Calling Settings that shows up when I do a search for it in the settings. Also if I look at the Apps and "Show System" apps, Mobile ID is there which is the Sprint ID software I believe, but again it is Disabled with no option to enable it.
The WiFi calling is turned on in the Ting account.
The Calling Plus feature was disabled by Sprint in that link you shared, but that just disables WiFi calling over LTE. It does say regular WiFi Calling should be available.
On my phone when I go to Network & Internet > Cellular Networks> I see my Preferred Network Type which was Automatic, I switched it to LTE/CDMA. That does not seem to have opened any additional settings for me in the dialer or elsewhere.
Thanks again for all your support. If you have any other suggestions, let me know, but you have offered a lot already.
