Wifi calling for T-Mobile

Hi will this work on the captivate?

Assuming you start at step 7 skipping the cyanogen mod flashing.
And yes I am using a Captivate on T-mobile. My data plan does not allow for the usage of T-mobile branded Android phones.

Really? :facepalm:

What's wrong with those instructions? It seems as though it just adds certain functions to the kernel for the app too call on.
Sorry I am just trying to figure out how to get this working because I am in a no reception areas for about 5-7 hours a day. This would really help allow me to get service and possibly save on battery life so that the phone isn't searching for a signal constantly.

There are some people who use the Captivate on T-Mobile. A few people have asked if it's possible to still add this feature in the Cognition thread and I have not seen an answer yet.
To answer the OP I'm not sure if it would be as simple as that since you're also flashing a kernel.

Has anyone tried?
Sent from my SAMSUNG-SGH-I897 using XDA App

if you read the instructions, you clearly need a modified kernel.
we don't have a kernel source to modify. on top of that, for the people who *can't* use it, it would just be a source of potential trouble. if you're on t-mobile and want to use t-mobile features, I suggest buying a t-mobile phone.
until we get sources, we likely won't see this on captivate kernel (as for a vibrant kernel, it's possible, but that has it's own source of issues)

Hey, come to the cognition IRC... I have some stuff you can test, I can open the app and such, but I am not on tmobile, so no way to test it beyond that.

Yeah when I get out of class ill gladly test out some stuff for wifi calling. Ill also have to figure out how to use Irc again. Any helpful guides? Wont be out of class until another 3 hours.

As an update, me and designgears tried several different combinations to try this out. So far I flashed a full Vibrant rom onto my Captivate and got the Wifi Calling to work. The keys were a switched because of the Vibrant Kernel but it was definitely working. Now if only we can port this feature over to the Captivate roms.

are you serious about this? what other quality benifits are there from flashing the full vibrant rom? i'm using simplemobile which is a sister network to tmobile. If you can post a link to it with instructions on how to install it I would be glad to experiment with you!

I literally just flashed one of the custom Vibrant roms in the Vibrant section using Clockwork and it worked just fine. Just some of the buttons were misassigned due to it running a Vibrant kernel.

Did anybody ever got wi-fi calling to work on unlocked captivate on T-mobile network?
Flashing vibrant ROM sounds interesting, but I would prefer to keep captivate rom on captivate.

I wonder if any roms have implemented this yet. I've been looking but found nothing. It would be a great feature. And to all you smart asses that keep saying "get a vibrant," I'll gladly swap your vibrant for my captivate. No? Well this is the phone I have and that's what I'm modding. So keep it to yourself.

Wow, I'm on a 'pay as you go' plan on T-Moblie with my captivate. I would love this if it worked!

So ... I have the Captivate and TMobile and need wifi calling. Can you help me? THanks.

[Q] What is the best Captivate ROM?

Which ROM is the best for the Captivate?
I have been running Assonance 5.2 since I rooted, but have recently been looking for something more. I have heard good things about Paragon and di11is ROM. I need full GPS functionality so ROMs without it are a dealbreaker.
Let the discussion begin.

I personally like darky's a lot. The most recent versions have added easier support for the captivate but may still need some work to get working. I love it though.

http://forum.xda-developers.com/showthread.php?t=919816

Andromeda seems to be the overall top at the moment. I know we're supposed to say "its preference" but no bull**** its the most stable rom and the quickest.

I'm aware of the FAQ, I've flashed ROMs, and unbricked my phone. Just trying to stimulate a lively discussion.

Fixed that for you, seriously just try them all based on what theme you like and what kernel features you need.

They all are good, some are better, all have bugs. Anyone who says other wise is lying to themselves

I really like serendipity. fast, stable, awesome.

ive tried cezars, cognition, and firefly out of those i liked cognition out of the box but loved firefly after some tweaks i think if u want stable go with one of the rogers 2.2 based roms

99% of the time no one starts a flame war except the people flaming the person who started the 'flame war'. Honestly though it is preference (although some ROMs are better then others stability wise)

I've found the same, big fan of Firefly right now, I used the firebird kernal with ADW launcher. It's about the best my phone has ever run.
The reality is that they all work a bit different on different phones, your going to have to experiment with a few to find the one that makes your phone happy. I understand how this seems strange, they should all be identical ( it's the same hardware right? ) but it's not so, for some reason they behave differently.
Good luck finding the combo for yours.

Check my signature. Results speak!

I've been using Darky's on my Captivate, and it's been running amazing so far.

How come no one mentioned Pheonix rising?! I've tried cognition but this seems better stable and fast. And With the GO launcher my life has really changed.

Andromeda is really great. Can't say enough about it. turned my cappy into what I thought it would be when I bought it.

Yeah I'm a big Andromeda fan too. I also like Perception with the latest Speedmod kernel. I was running Paragon RC3 and got amazing battery life from it but overall it was kind of choppy and not as smooth as Andro and Perception/Speedmod. If I was going on a long trip I would flash Paragon and pop in my 3000mA battery. But as my daily driver I like Perception and Andromeda.

Keep coming back to Cognition 3.02. Just flashed Firebird Kernel because I wanted to enable HSUPA and Voodoo Sound. Went though I9000 JL3, JK4, and JK3 modems. In call volume on most I9000 modems are pretty low, but that can be fixed. However, I was having GPS problems with every modem I flashed, BUT, I came across the KP1 modem and it's working very well. Good call volume without tweaks, GPS lock in 10 to 15 seconds (within 10 to 15 meters accuracy), and solid upload/download (~1500 - 1700 kbps download / ~12000 kbps upload)
My phone really doesn't seem to like I9000 ROMS, though, and I've tried mostly all of them. Serendipity seemed to run the smoothest, but I didn't get good GPS performance so I went back to Cog 3.02, but that was before I came across the KP1 modem. I'll probably give Serendipity another try with the KP1 modem before too long.
Just like everyone says, it's all up to personal preference. I've had my Captivate for six weeks or so, and I'm starting to find out that the ROMs offered by the great developers who post on XDA are fantastic in and of themselves, but they can also be great starting points for you to find out what works on your personal device. Different kernels which support certain lagfixes, video and sound enhancements, and different modems are available so that each individual can find out what combination of ROM/Kernel/Modem works for them.

I haven't had my Captivate very long but I've flashed Cognition, Andromeda, and Serendipity already. The best so far for me in speed stability and appearance has been Serendipity. Just my opinion as everyones Captivate is different.

Serendipity bar none!!!

>>In call volume on most I9000 modems are pretty low, but that can be fixed.
How? By switching to a different modem, or what?
It would be nice if there were a chart that listed modems and kernals, showing the features in each and their compatibility with each other.

Captivate vs I9000 Based Roms

What's the difference between ROMs that are based on the Captivate such as Cognition vs ROMs that are based on i9000 such as Perception? They both function more or less the same according to my usage.

One of the main diff is that Captivate based roms are 2.2 as where i9000 roms are based on 2.2.1. Some give you more options then others as I hear only certin things are available with 2.2.1.

Usually the i9000 roms are faster, and also allow do HSUPA.

have a look here for the updates. I think one of the main things in 2.2.1 were the exchange policies as Android is working its way to be more business friendly and Develoment minded.

Yeah, I can't connect to my work email using the 2.2 email, 2.2.1 email works fine however.

yes interesting i have cong 4 was wounding same thing still a bit fuzzy

Captivate better for me
I've found my phone works smoother with a captivate based rom.
Cognition is all captivate and things seem to work better
less force closes and unresponsive touch screen issues on my 1007 revision captivate, as well as dramatically less dropped calls
I lose HSUPA, but I'd rather have stability.
Cognition 3.04 with the stock rogers modem and with DA_G's gps fix also gives me pretty impressive gps performance on my captivate
I already paid for touchdown so exchange isn't an issue for me.

HSUPA comes with the modem, not the ROM. Just flash the correct HSUPA modem and you're good to go.
For a normal user perspective, so basically there's little to no change. What about bluetooth? I need that for driving and atm, Cognition + Firebird/Speedmod does not support bluetooth calling.

bump on the bluetooth question and of course on any other things you noticed

Ok, a couple points here:
1) I recently flashed a Captivate-based ROM for the first time in months, after flashing every i9000 reorient out there a dozen times. WOW. What the heck was I doing? At stock clock speeds (with a custom existz kb1 kernel and voodoo fs), the speed and smoothness and snappiness and sound quality and battery life of my device completely blows all i9000 ROMs I used out of the water. Maybe it's just my individual results, but it seems to me that there are still, despite all the much-appreciated hard work of kernel devs and ROM chefs, a ton of problems with how i9000 hardware works on the i897. It's great that I could get better dl/ul speedtest results on the HSUPA, or better Quad/Linpacks with OC, but in practicality, the process of downloading and installing an app on kb1 without OC is still WAY faster. The only ROM that compares is CM7. I'm not anyone's Director of Development, but I'd urge the devs here to focus on i897-based code and binaries whenever possible.
2) When I was using Cappy ROMs before, I know I had to use Bluetooth Launch and set it to the Voice Search VoiceRecognition Activity, thus enabling all Google Voice Actions including dialing over bluetooth. Today I'm going to play around and see if I can still get that working or perhaps tie it to the Voice Dialer app instead.

[Q] Hello there, can someone here recommend me a ROM please?

I'm a new user here (yes...I read all the faqs) but I'm still not fully aware of the ROMS available and their respective benefits. Didn't really see any threads that helped me in the captivate section.
What I'm looking for most is excellent battery life and signal (if that's possible). I tried Cognition and it seemed alright for a bit but then my signal became spotty and battery worse (not sure if it was the ROM or my phone).
If it helps: I'm on stock froyo (on Rogers).
I'm not really interested in a multitude of features that may overload my phone, I'm a minimalist.

You could always try flashing a different modem if you're having issues with signal.

I've found Continuum 6.1 to be the best operating gingerbread ROM for my phone. This after experimenting with pretty much every other ROM out there. Battery life has been good.
I'm a moderate user. Mostly sms and music. I get 2 full days out of a charge when running the music app 2 hours per day and sending 20 or so texts.
This is purely anecdotal. My wife's phone got poor battery life out of the same ROM. Just going to have to try one at a time until you find one that works well for your phone.
Good luck.

Are you looking for a ROM based off gingerbread or froyo?
I would recommend a froyo based rom for stability, serendipity 6.4 treated me pretty well when i first started and now i'm on fasty 2.3 which is pretty good too.
If you live in the northeast USA then i would suggest JW2 or JV5 for modems.
(See this link for modem options and good discussion on the topic, http://forum.xda-developers.com/showthread.php?t=876391 Ignore the poll, its out of date.)
If you want to try out the tasty goodness of gingerbread then i suggest trying serendipity 7 or the leaked "stock" 2.3 ROM thats been out for a month now.
Keep in mind that you are more likely to find bugs and random problems with gingerbread ROMs since most (all?) of the current ones are not based off of the i897 captivate ROM but the i9000 instead.

You're going to get a multitude of suggestions being that everyone has their own favorite. What works for some may not work for others. I personally have found that I can get healthy battery life out of most any rom I flash using an OC/UV app. Usage and location has a lot do with it as well. Your best bet will probably be to try different things and explore on your own til you find what works for you. Luckily there are tons of people in these forums who are eager to help and lend advice. I certainly wouldn't have learned as much as I have without them.

Stability and battery life = serendipity 6.4.
Stability on gingerbread = serendipity 7
Awesome features(but you don't want these based off op) = MIUI
Sent from my I897 using XDA Premium App

For a froyo based ROM ill easily agree serendipity is the way to go
And look into the onix kernel
For a gingerbread ROM try either continuum or apex, but avoid the betas just use the stable releases
And look into the talon kernel
Both kernels I recommended are by the same dev and are capable of overclocking (which you don't seem too interested in) and undervolting (this will help with battery life)
If you want to overclock stick with 1.2 ghz, anything higher is usually unstable but you could get lucky, 1.2 is safe though.
For undervolting read around for the guides to oc/UV. Make sure you have a way to wipe your voltage settings if you mess them up (should be built into onix's recovery, and its definitely in talons recovery)
No matter if you choose froyo or gingerbread and whether you use any of my suggestions above, look into the gingerbread bootloaders (try to avoid the i9000 ones, even though they work on the cappy they weren't made for us) I don't know if there are rogers bootloaders for gingerbread but I know the att ones work great and you can probably change the logo later.
The gb bootloaders are obviously required for gingerbread roms, but will work with froyo roms as well, so you may as well grab them now.
As for signal read into modem flashing, make sure you get cwm2 flashable modems for cwm2 recoveries (like onix) and cwm3 flashable modems for cwm3 recoveries (like talon)
Your best bet here is trial and error
Jk4 seems to be a good fallback modem for functionality (no frequency dancing issues which can cause roaming or no signal) but I'm not a fan of its signal strength in general or battery life, personally I like kc1 and zsjpg depending on what region I'm in.
Anyway I hope this info helps

Try them out for yourself. We can give you what,works for us but might not work for you. A search would have told you this. Thread closed.

Help choosing a modem.

I'm currently switching up ics roms and kernels to see which works best for me but I do not understand modems so I need some help here. I saw jk4 on the map close to me. I live in jacksonville fl and commute all around the city and west of jacksonville daily I was wondering which ones to try out.

Just start downloading them and trying them, giving them about 2 days before you decide if you like it. Several factors to consider are call quality, signal strength, battery life, and GPS reception. Since your using ICS roms, you must use the modems packaged as CM7/MIUI. You try using something else and it won't flash.
Look >>HERE<< for all the modems you would ever want to try. (FWIW, I like BVJWW2)

Like mrhaley said, there are a variety of things that affect it. JK4 worked great for me when I was in Florida, so I would start there. JW2 is nice also, but it seems like people can't hear me as well with it.

I'm thinking it might be something related to the modem.

Someone listed the "UGKC1" modem in use in Panama. You might consider UGJL2 or UGKG3 also, near by. Search "soggy cashew captivate modem" and check the map. Update your own listing if you find something that works.
