Many of you are aware of a thread in the Focus S section of this forum about someone with their Focus S getting VVM to work. However, it wasn't the most helpful thread to replicating it. I have since replicated this on a different device (the Focus Flash), so I wanted to post something here to let more people know.
Thanks to davezaff for the idea.
Here is how I did it on my Focus Flash. You will probably need a way to edit the APNs.
1. Update to 7740
2. Update to 8107
3. Insert sim card into an AT&T Android LTE phone (I used skyrocket)
4. Go to att.com and switch plan to Data Pro 4g LTE plan. I had to call to switch since it wasn't working on the website.
5. Setup VVM on Android LTE phone (don't know if this is necessary, but this is what I did....make sure friend knows the VM password so they can re-add it when they put their sim card back in.
6.Insert sim card back into Windows Phone
7. Call Voicemail
8. Wait for VVM to show up on phone (mine showed up after calling voicemail).
9. If sync error, edit the APN as follows
APN settings (delete the internet_line APN)
Create a new APN
APN Name: pta
Profile Category: internet (always on)
APN: pta
Auth type: None
Username:
Password:
Proxy address: proxy.mobile.att.net
Proxy domain:
Proxy port: 80
I now have working VVM on AT&T with my Samsung Focus Flash. My internet tethering still works (applied the Interop unlock + tethering hack from XDA). I have not tested MMS since I did this, but the MMS APN was untouched.
So they have tied vvm with their stupid data plans, how nice. So I can pay $20 for 300mb + vvm or I can pay $10 for unlimited data and traditional vm... ATT is so dumb.
Moved To WP7 General​
This is not development, its more of a guide. Please post such threads in the WP7 General section​
For the normal person, it is pay $30 for 3GB of data with traditional VM or pay $30 for 3GB with VVM. The only difference is one plan has the word LTE at the end.
how can one even get the 8107 update on the samsung focus s? i tried the old force update method (disconnecting the internet connection) with zune, and that hasn't worked...

Yes, and just download the English only language pack.
i already updated to 8107, but im asking if the vvm works for the titan, i also don't know anyone with an LTE android phone
Does this work if you don't setup VVM on the android device first? I was thinking of just calling AT&T and asking to be switched to the 4G plan.
Get it working without an LTE device
OK, I got this to work on my Lumia 800. Furthermore, I didn't have an LTE device.
What I did have however, is an AT&T store that caters extensively to my place of work (a software company). They are really nice, understand unusual requests, and try everything to help.
I did the following:
1. Upgrade the OS as per the original post.
2. Call the nice AT&T store that I mentioned above. Asked them to put me on an LTE plan. (I was already on an enterprise plan, so I was moved to the same enterprise plan but the LTE version. Cost of my plan remained unchanged).
I explained that I was doing some app development, and planned to be swapping phones from time to time, some of which are LTE phones. (I also have a microsim adapter, so moving between phones that take microsim and regular sim is not an issue for me).
They asked if I'd like VVM provisioning. I said yes.
They told me that they would change my listed phone to a blank IMEI (basically change the IMEI listed on my account to a blank IMEI that's associated with an LTE phone for provisioning purposes). I don't know if this is something all stores would be willing to do.
3. In the APN settings, I changed my APN to pta. I did NONE of the other settings mentioned (proxy, proxy port, and everything else are BLANK).
Now I have Visual Voicemail on my Lumia 800!
Hmm so why is vvm only available to LTE phones/network I want to get this.

I wonder if this blank IMEI is a special IMEI that at&t has to test LTE devices on accounts or something. I wonder if this IMEI would also work on other accounts as well. Hmmm.
I don't suppose that IMEI is something you could share possibly? I mean if its not a real phone, and can work on multiple accounts, it would be very nice to (selectively) share it so that some of us can get VVM.

I agree, since I just called asking for essentially this setup and they deniened any special IMEI.

So i also have an 800 and asked them to provision me for HSPA+ recently, so they switched my data plan to one that was supposed to be able to access it (i have no idea if it really can - that's a whole different can of worms). What did they switch your plan to? If you look online and hit "recent usage", you can see under "Additional Data Purchased Usage" your data lines with the plan code. My code is "HSSMTD4O" Just wanted to see if i could skip the "call att" step.
Thought I would share my experience also..
I was able to get VVM working on my Focus Flash. Luckily I have a friend that works at the ATT store. He just took a Samsung Note scanned the IMEI and added that as my phone. Then he enabled LTE and VVM. I rebooted phone and went in the the phone tile, and VVM prompted me for password. I put in password and all has been good.
The easiest way would probably be to borrow a friends VVM supported phone and put your sim in it, then have them add VVM to your account.
I did not have to add any APN's or make any changes to the phone.
Getting it working without a LTE device and without AT&T in your pocket
So, I decided to try and get VVM setup on my Focus S today, but I have no friends with AT&T and the local store was unwilling to help in the fashion outlined above.
So what to do? Well the main thing you need for this is the IMEI number from an Android LTE phone. So I asked a couple friends that don't live close by, and none of them had a LTE phone.
So I searched the internet for those "Get unlock Codes" websites, specifically for tutorials on LTE phones, and some of them show the IMEI number.
So I went into chat support and told them I needed a LTE plan with visual voicemail, and they asked for the IMEI number, I gave it to them, and then 2 minutes later VVM is now provisioned and working properly.
Yeah so I ended up adding the IMEI of a random Galaxy Note that I do not own. It was dead simple to do it online through tech support chat. After that, just called up voicemail, waiting a second or two, hung up, and then my phone prompted me for my voicemail password and automatically enabled visual voicemail. I realize that AT&T's system does not check for duplicate IMEIs across the network, so you can throw the same IMEI onto any number of phones and AT&T wouldn't know a thing (until they start looking of course).
I did have to change my APN to "pta" to get it to sync properly, but after that it was all smooth sailing.
Now I've got Visual Voicemail on my Titan and Lumia.
I am glad some of you were able to get it to work. The big issue I had before starting this thread was getting the APN settings. After getting VVM enabled, it couldnt connect until I messed with the APN. Glad I was able to help y'all!
Hi,
1. I bought a Samsung s4 mini SGH-I257M, locked by Telus.
2. I tried install super root, but each time it tried to launch the application, a shield from up-left corner will block it to run.
3. I asked a mobile shop unlocked for me with Z3X, but the sim card cannot be registered (the sim card is not from Telus.) Every time when the phone try to register the sim card to network, there is a small shield icon will shows in the up-left corner and blocks it.
4 After two days, I went to the shop and got my phone back. I rooted my phone with Root Dashi, a chinese root software. It works! I inserted a Fido sim, the shield no longer there, but I still cannot register my phone to the network. Any idea?
Sorry for my English.

Rooting and carrier unlock are not the same thing. it sounds like you do not have an APN for Fido or slightly possible the shop was not successful, but if so the Fido SIM should prompt the phone to ask for an unlock code.
If so, there are tons of outfits that offer carrier/provider unlocking. You can Google the string "carrier unlock SGH-I257M". You will find How to videos on YouTube regarding unlocking as well.
But likely it is just a lack of an Fido APN not allowing it to register on the repeater. I looked for the APN BTW, No luck.
You might also do some XDA searches on Chinese online Rooting. The XDA Developer Arco68 has an excellent method that works very well on your phone if you should loose the root you have.

What do you mean "do some XDA search on Chinese online Rooting".
Should I ask Arco68 and see is there a i257m ROM for me?
When I power on my phone with Fido SIM card, it won't ask for unlock code any more. Where I can get the APN setting?

There are several threads on XDA about Chinese online rooting, it has been found that IMEI's, personal data and so forth have been transmitted to the host servers in the rooting process and links on XDA (wisely) have been banned until the matter has been fully researched. There is a good search function on these forums. You can find info.
Asking a developer for a specific ROM is bad form, just asking generaly in the Q&A section in will net what you are seeking. The Dev's are not paid, they donate serious work to the community as a whole, Read the forums for the i9195's, those are the ROMs available right now.
Read up on APN's, locate Fido users, call fido, do research. Anyway, hope some of that helps, it's about all I know about Fido. Learning with some effort is well worth the time spent. No one is born knowing this.

Hi Systwk,
Thank you! Actually I use Chatr, not Fido. Because I don't want damage my current SIM card (cut to micro), so I use FIDO sim card which is currently not in use to test my phone. I got my SIM adapter today. I cut my Chatr SIM card and tested with my phone. It says registered on network, but the notification on the main screen says ?Selected network(chatr) unavailable", and I cannot make any calls. When I choose "Select automatically", it will say "unable to connect, try later".
Do you have any idea?
BTW, I tried with APN FIDO, it's not work.

farewellartist's suggestion is a good one. It could help to see what is going on. That aside, you have to use an APN that matches the network you intend to use and the account has to be active. Also the network protocol set on auto shows it finds the Network, the Sim and phone can connect, but it also needs to know how to communicate with it to register on the system. That's possibly the issue.
You really may find some help calling your Providers tech support regarding connection. Yes, that about as fun as banging your toes with a hammer, but usually has better results. It may be as simple now as plunging in an Access Point Name, user name and password in the APN. (Some Pre-Pay acct's use user and Password) Good news is you DO have connectivity. It's now down to details.
Keep plugging along, you are making progress.
Here is the support link for their Pre-Pay. I'm in Florida so I'm clueless regards to who you are dealing with.

You are certainly not weak on signal. As long as you have the APN set at 'APN: chatrweb.apn' you should register.
Rare as it is, Bad SIMS happen. (Murphys Law). Just to rule out you can try the below and I Know the steps getting there are not needed, but it's for others in the future who may be newer at this:
To check connection at the base level try the following.
GoTo: Settings-Connections-Network connections-More networks-Wireless and networks-Mobile Networks-Network Mode, THEN start ticking the 4 setting starting with GSM only, and work upwards. It can't hurt.
Also when trying to connect with chatr, in the search for Network operators/Available Networks in mobile Networks, when it's done searching nets available, choose one chatr. not auto. If it finds two chatr towers try each.
I'm adding the chatr APN for anyone in the future as well. I assume you have the same but it's not in the screenshots.
You must be frustrated by now, hope someone else with experience on chatr can offer a fix. I assume you did get on either Telus or Bell so you know the thing connects, a replacement SIM is the last option I can think of.
Good Luck.............

If it were me I would not re-flash anything. The connection problem would not likely be from a carrier unlock. Also it is not likely it would be from rooting or installing the CWM boot loader.
You have a known system now, you know when it worked, and you know the few modifications you have done. Even if you have called Chatr tech support before, it might help to call again and tell them it will not log on to their system. DO NOT tell them you have rooted the phone, DO NOT tell them you installed a boot loader. If you do that, they will probably say that is the problem, END of support. Just say it was unlocked by a dealer and now takes their SIM but it won't work.
They should walk you through each step of the configuration, they want your money every month, you want their service. Good place to start. Give them your IMEI, make sure it's good and not 'blocked'. it's in the settings/about device/status or dial *#06#. I'm assuming you already have confirmed your phone is comparable with chatr, I think you mentioned it was from TELUS, but with BELL, ROGERS or whatever, unlocking does not guarantee the Modem is the same as the new network you are trying to use.. There are several other reasons, but SIM, IMEI and improper configuration are the most likely problems if compatible.
There is a chance it is something simple that has been missed. You have shown patience, that is a big plus with modding phones. Going step by step and being willing to start over is something many here have done, and many times. Small problems are sometime the easiest to miss. So Call Chatr tech support, if they have an outlet near you maybe you can get a replacement SIM from them, (I would check that first) as I mentioned before.
One other thing to try, see if you can get a new Pre-Pay/month to month SIM from TELUS or the original carrier the phone was branded for. It should work and if not, they know their configuration. I'm out of suggestions, hopefully someone from Canada can be of more help. Don't give up. There are always answers.
Thank you, Systwk
The SIM card works with my old phone, so probably is not the SIM card problem. I take out the SIM card from S4 mini and power on it, the signal still shows good. So, I think flash ROM is the most simple way for me. Anyway, I will can chatr on Monday.
Hi Systwk, I called Chatr just now. She said the APN setting is only for Internet and I need to go to a Chatr shop to check my phone and SIM card. I think I will go this weekend.
I think you bought the phone that has been report as stolen and has been blacklist so it is block on all network in Canada.
QCN FILE
If you are having a problem getting a signal on your I257M message me I will send you the qcn file for it so you can write it to phone via QPST.
So I'd like to be able to use Google Messenger. I like the material design a lot.
Unfortunately GM has major issues with MMS due to how it utilizes APNs. It's a known issue with a potential fix if you're able to add/edit/delete APN's.
I have a retail VZW note and don't see that there's any way to do anything with the APN. Am I missing something or is the completely locked down on this phone.
If there's a work around, I'd love to know about it. Thanks for the info!
I would like to know the answer to this too. I'm planning a trip to Ireland and North Ireland and I would like to use a local sim card to access cell network and mobile data. I'm pretty sure I will need to add a new APN and edit the settings to get this to work. Is this possible with the retail version of the Verizon Note 4?
Yes, it's possible, but you can't do it in advance. If you pop a different carrier's SIM card into your Note 4, you will then be able to edit APN's (I popped my AT&T work phone's SIM in and was able to add/edit an APN).
For whatever reason I can't get my totalwireless sim to connect to data in my pixel 2 xl. The sim works fine in my pixel. I can put a xfinity mobile sim in the pixel 2 and it will connect to data just fine. I can't even edit the apn settings when the totalwireless sim is in the phone. It just tells me I'm not authorized. Anyone got any ideas on how I get my pixel 2 to connect to LTE on totalwireless?

Get a new sim from them. Sprint is the same way
Sent from my Pixel 2 XL using Tapatalk
Got a new sim, activated it with the pixel 2 xl imei. Still no data, cannot edit the apn settings. The new sim also works fine in my pixel 1. Google just tells me to factory reset or reset network settings. That doesn't help. Totalwireless wants me to manually add the apn, which I would have done from the begining but the apn settings are locked and I cannot change them. Just going to return the phone as its not really useful without data.
A fix!
munkle,
Me and another reddit user have been battling with the same issue. I've gone through 3 Total Wirless SIMs and haven't fixed the issue. It has to do with not being able to add or edit an APN on the phone. Another user figured out a workaround though. I'll copy his reply here. I haven't tried this yet but I'm going to try it this weekend. Here is the quote
"Holy ****, I think I've cracked it.
This is the most convoluted set of steps I think I've ever had to do on something that should be easy... however this answer is kind of a pain.
I managed to get my hands on a H20 wireless sim crd which uses the att network. As I said before it lets me add an APN but not save it. So what I did is leave the screen open where I entered the APN info. swap out the sim cards in the middle of it and hit save whenever the phone got service and bam! LTE!
I can't believe this is what I had to go through... And I can't even promise it will work every time. I tried the process again on my RMA phone, but all that phone would pick up is 3G... go figure... So I think your best bet would be to swap in a buddy's sim card who uses att or tmobile, just to get to that 'add an APN' screen and then swap your sim card back in."
I can confirm that the above works. I now have LTE data. That is messed up that you need to do that.
Edit: actually it only half works. I still can't send mms messages. Probably because the apn screen wouldn't let me exactly match the settings on my pixel 1, it says the carrier didn't support certain things.
See this topic: https://productforums.google.com/fo...!msg/phone-by-google/_PGJbTEuY0M/BY724wAkBwAJ
It's the future of android, unfortunately, in that it's an android 8.1 issue (at least Android 8.0 on 1st gen Pixel XL doesn't have this issue, but Android 8.1 on 1st gen Pixel XL does have this issue).
There is a new setting in the apns-conf.xml file (found in /system/system/etc or /system/etc), which setting is labeled "user_hidden" with options "true" and "false". All of the Verizon MVNO settings are labelled as "true", meaning that APN editing access is now restricted.
There is no way that I know of to edit this file without bootloader unlock and root.
And, it's definitely an Android issue, as Android 8.0 (other than on the Pixel 2 XL) and earlier did not have this issue.
Speculation on my part, but this is probably Google's response to its exclusive carrier, Verizon, request that these phones not be made easy to use on much-cheaper-than-Verizon MVNOs.
If you have a phone which needs APN settings modified for it to function fully this may be of interest. In many cases you can simply go into Settings > Network > Network and Internet > Mobile Data and add an APN or edit an existing APN.
However in some cases you may find as I did that the SIM / phone combination does not allow you to edit or add APN settings. If you have root their may be ways to edit the APN configuration files directly. However with Android 10 and some other situations that becomes difficult if not impossible. In my case even the phone network service support could not update the APN setting. I knew what the APN settings needed to be but since I had an unrooted Android 10 device (a smartwatch in this case but it will work for phones also) I could not get access to folders to edit the configuration and it is unlikely it would have been saved due to Android 10's read only system partition.
On this device I had cellular phone calls and text working but NO Mobile data. I could see the APN settings were not correct for the service I was on for Mobile data to work. I tried everything for days to edit but it was grayed out and I could not add a new APN. In the process of pursuing a solution I found that putting in a different SIM (in this case a Textnow SIM for their new free phone service through Sprint) that I could edit the APN settings when that SIM was inserted. So you will need to find a SIM card that will allow you to edit settings.
Now the real trick involves hot swapping SIM cards so if you aren't comfortable with that then you won't be able to do this. There seems to be differing opinions on this but no phones or watches or SIM cards were damaged when I tried this.
What I did was edit the other SIM by changing the APN settings. Then when I hit the back key it said something to the effect the settings were not allowed on this. At that point I pulled out the SIM with the device ON. I then put back in the SIM for my service provider with the device still on. The settings showed up now on my formerly uneditable SIM ! Mobile data now worked fine. I
I had a second device I wanted to put the SIM in (identical to the first device) hoping the settings would still be there but they were not. Apparently communication between the SIM card and the phone gets APN settings transferred to the phone or watch. So I wanted to do the same procedure on this second device. In attempting that it did not seem to be working the same at first. However after trying for about an hour it finally worked on the second device also. So persistence pays off if it doesn't work at first. I kept turning things on and off in the Mobile data settings, rebooting and playing around with developer options. I wish I could say exactly what got it to work on the second device or why it just worked on the first device the first try but I haven't been able to pin down the variable which achieved success.
But the conclusion is that is you can't edit your APN settings normally you may have success with this method if you keep at it a bit. Good luck and please post here if you have success with this method and share any insights into how you got it to work for your device.
I know I'm a little late your one man party here. I just wanted to finally clear the air on this once and for all. So that every one can edit any and every so called "locked APN" for whatever carrier and or devices. So here we go. First off long time telecom cyber security engineer.
Step 1: Find all the APN's that your specific Carrier used for your Sim card and device. Write them down or screen shot them. Some carriers and devices may only use 1, others 2-3 +.
Step 2: Click and add another APN just as the 1 that is locked on the device. Option for option identical and click save. If you have only 1 APN. It should have now saved, unlocked the APN and you should have 2 identical. You can now go back and edit the APN that you just created. If not or you can't it usually means you have more APN's to add before they will unlock. Ultimately allowing for deletion. Have patience as this may require a little time of trial and error. Good luck all and have fun with it.
