GSM ROM question - Xperia Play Q&A, Help & Troubleshooting

I read something about you could install a GSM ROM on a CDMA phone if you but you would have no data. Excuse my noobishness, but what exactly would cease to work? 3G obviously, but I generally only use WiFi. So texting and internet via 3G would be down, but calling would still work, right?

Calling also uses that CDMA stuff, so no, calling wouldn't work. You would have no signal whatsoever, unless you were using wifi.

Can't receive call while online

Today I was listening to Windows Media Streaming audio, and the phone apparently would not let calls come in during that time.
Is this a limitation, or by design?
Seems to me the unit should funcion as a phone regardless of whatever else it is doing?
I don't know if this is a WM6 issue or not, but since I upgraded and did not try this before the upgrade, I put it in this section.
TIA
Were you using wifi?
If you were using 3g it should have worked - over gsm it wont.
I was not using 3G or wifi.
I was using GPRS (E) streaming data - so I guess that means I was using gsm? 3G is not yet available in my market. Also, is this documented anywhere (other than your answer for which I appreciate)?
Thanks!

I'ts a well known fact; no simultaneous voice & data with Edge/Gsm.
For documentation, try googling some of the words included yours, mine, or unwired's post.

Wifi calling port from G2? Will it work for an Evo?

Would it be possible to use the wifi calling feature from the g2?
Sent from my PC36100 using XDA App
Just saw the header at AC. Is it free WiFi calling or something?
Has to be since you can already make calls over WiFi with the Evo ... right?

err i don't think it works on Evo.
It's available in Android 2.2, but it's up to the network and the phone developer to allow it.
Not sure why I said has to be, or what that even pertained too.
Was more a question of "why" since you already can, unless it was free. Can't find any info on it being free, so why port? Even if it worked, unless it was free. Guess that's what I meant if that even makes sense.

I believe that part of the UMA technology that allows wi-fi calling is hardware based but I wonder how the wi-fi calling works? It might not check back with the network looking for a feature to be on your account, it could just route it via WiFi. I really don't know. It would be helpful to have a dev look at the .apk but I haven't seen it posted or seen the OTA for the G2 yet. This would be WONDERFUL if we could get this working!
Sounds like it would be routed as voip with you network number.. Kind of like an airave.

I am pretty sure that the Evo does this already. I heard a Sprint employee say so in a store (though that should hardly be taken to mean that it is fact), and I can make and receive phone calls in my office, where I have zero cell service, but do have wifi.

BS. Sprint doesn't do calls over WiFi. Odds are, when you made the call, it dropped to the 1X 850MHz network, but when you looked at the service bars, it was on the 3G 1900MHz network.
As for the OP, no, it won't work. The T-Mo' WiFi calling will use their private VoIP servers and accounts. Your best bet is still to get your own SIP client (like Sipdroid), provider (like Sipgate), and tie that into Google Voice.
IMHO Our best bet at WiFi calling (On Sprint) will be with using a solution via SIPDroid, Nimbuzz or Skype.

[Q] data lost while on call

when i am on a call i cant not see to get data...the data connection turns off by itself and when the call ends data connection will come back on? is it suppose to be like that or is there something wrong with the phone. right now im on software 1.28.708.10. thanks

Happens to me too I believe my frined.
It only happens with mobile data though.
If you are on Wifi, the wifi should NOT disconnect right?
ya if it is on wifi then it is ok. not data connection though
I believe that the phone switches to 2g during calls, and not sure whether this is a telco setting that they do not allow calls through 3g, or a software feature of the phone with the reasoning that 2g signals are generally stronger in most parts of the world compared to 3g.
Just fyi i had the same issue on my "old" Desire HD.

It might be carrier specific. I have no trouble getting (and keeping) HSPA data when I'm in a call.
which version do u have Barry? I am using the international version on rogers. Are you using the at&t version?

Then I believe it to be carrier specific then since the software governing these kinda things should be standard across the board

A UK international version on AT&T.
Ok that is so strange. I have the Hong kong version on rogers network. It never happened to me before and I have used a lot of HTC and unlocked phones before.

ok so i dont think its the carrier cuz i reset the phone and it works sometimes now. if i make a call and browse right away then it will work but if i leave it for too long then it wont work.

guys its because the phone calls you make are on a 2g bandwidth unless its a video call, that's why if you have 2g connection or EDGE active it will get disabled as soon as you make a call.
to clarify, force your network settings to wcdma and then connect to 3g, after that make a call and your 3g will not be disconnected

Hi Marktang... I saw your post from Google as I lost data connection during phone call with my Galaxy S2.
May I know is it after configure the Network Mode inside the setting to use WCDMA only, then the problem will be solved?
Thank you...

Wifi calling for CM10

Looking to enable wifi calling for CM10. It is obviously there in the default Tmobile stock.
Not possible for CM10 and developers will probably never build it in since most phones/providers don't support wifi calling. Also, unlike phones like my old HTC G2 where wifi calling is a separate app, the SGS2 implements a new version of wifi calling that is built into the ROM.
Bottom line, if you need or want wifi calling, you need to be on a TW ROM, no if's or but's about it.
Sent from the pink Unicorn from the Darkside.
Thanks for the info!
Actually, these guys are really misleading you. It's not that it can't or won't be done, it just hasn't been done yet.
There was even a version of T-Mobile WiFi calling that worked great on the HTC HD2 which wasn't even an Android phone, so it's completely false to say "Not possible for CM10", it just hasn't been done yet. They may be correct that it will never be built in, but someone will eventually make a derivative ROM that will have it, or you will have a flashable zip for it.
You can also use voip.

Groove-IP works pretty good
I've seen a lot of people suggesting that we use our Google Voice (GV) number instead of WiFi calling.
If I use GV, and assuming I set it up properly....
When people call my cell number, does it ring when I only have wifi and no cell service?
When I make calls out on WiFi only, so people see my cell number or my GV number?
In what ways is it different than use T-Mobile WiFi calling?

You can forward you cell number to your google voice number, when you want wifi calling. I have mine set up to start at 6pm till 8am when I'm home. Works perfectly. I use grooveIP free, with a strong wifi signal, calls are very clear.

I would be VERY VERY hesitant to flash something made for a different phone, much less different manufacturer. How about you try it and let us know. With screenshots of course.

can someone explain to me why wifi calling is cool?
WiFi calling is "cool" or useful because it allows for using WiFi as cell phone signal. I've worked in buildings which had no cell phone signal, and without WiFi calling, it would take hours for a text message to find the signal to creep through, so it was very useful.
I've tried GrooveIP and GVoice and they were way too buggy to rely on.

And to add to this...some of us use our voice in certain areas mostly (like home) and Wi-Fi calling allows us to get a low minute plan since Wi-Fi calling doesn't use minutes.

Actually it can or does use your minutes... I know sounds foolish huh. I've seen some discussions on this in a few different places/sites and I still don't have a 100% clear answer. On the TMOUSA site regarding wifi calling, towards the bottom in grey txt it says:
"Capable device and Wi-Fi connection required. Wi-Fi Calling may decrement plan minutes. Except for UMA devices, device will not transition between Wi-Fi and the wireless network."
I think it's a case of if you're using it excessively they would start to deduct it kind of thing, but who knows. It's probably so they can change their minds in the future without any hassle, for instance, if people are using the heck out of it and they are losing as a result.
By default, it will use your minutes but now they have a free WiFi calling feature that you can add which makes calls made over WiFi free + unlimited, at least that's how it was last time I knew.
I would also really love to see the feature added to cm10 someday... It used to come with cm7 when I used it on my G2.

force 3g?

.Hi guys/gals, just impoted a captivate glide from the u.s, seeing as they never released them here in the uk..
Its brand new, accept for the chap has already rooted it for me and installed cwm. Now after reading somewhere on this forum a while ago, I remember, I think, that you can only force 3g on the at&t rom and not on the rogers (which I'm running)?
Is that right? As I really need this feature, and have used it for years on my desire z runnng miui..
Are there any patches/cab files/apps that will do this for me, as I can't find a way to solve this without flashing the at&t rom..
Thanks peops..
(I also get a blank screen when activating wifi hotspot, which I use evry day also,,, this wouldn't be a common bug I spose?)
James.
As far as I know the only Rom that lets you switch to 2G (I think is what you want) is the ROMS from Rogers. You can use either the stock 2.35 or the OSIMOOD which is also based on stock just has the Bloat removed. Unfortunately all ICS roms are based on AT&T. I don't know what the JB ROms can do as I have not tried them.
Get pimp my rom. You have to get the hidden menu up, and change to GSM only. The radio has to be turned off and back on for it to work.

Hi, thanks for the replys, but its actually the other way round, I dont want it to keep dropping back to 2g, I need it to stay on 3g only..
Any suggestions?
Thanks..
Pimp my rom did the trick though, thanks
Any ideas on how to fix the wifi hotspot black screen (black screen, accept the top icon bar which is still visible)?
Thanks...
Force 3G Network
You only have to dial *#2263# and you well get the network menu

So you would rather lose data connectivity altogether than use 2G?
And if you're overseas, why do you have T-Mobile set as your provider?

Hi, bit late replying, but, I use the phone as a router via wifi tethering at home, so I want it to stay on 3g. Forceing it to stay on 3g stops it unnessaserily dropping back to 2g and slowing the connection down, it works well and I've always used this on my desire z via miui roms.
My provider is T-mobile.. T-mobile uk
Also, anyone got wifi calling working on this phone? On any rom? As I can't find any info on it.. as tmobile has free wifi calling over here..
Thanks guys..
am I the only person in the uk to use one of these? (If I am ill feel a bit special lol)
