[Q] Xoom MZ601 - USSD Disable Telephony - Xoom Q&A, Help & Troubleshooting

Hi all,
First let me say that you're making awesome things possible with such an old device (bit weird to say that about a 3 yrs old tablet ) Many thanks for all your efforts!
Either with current Omnirom and CM11 my Xoom is receiving voice calls. Regrettably the provider is not able to route calls just to one specific device (got three SIM in total as part of my contract). I can set mute for incoming calls, but the device is for my parents in law. So I'm not that interested in showing them all phone numbers that try to reach me...I could pay some money to get a data-only SIM, but then I could also use the money to buy a new device^^
I have already tried the following to solve it
- removing the Dialer apk -> no voice call button anymore, but it is still ringing
- added lines to build.prop ("ro.telephony.disable-call=true" & hw.nophone=true) -> without any effect, had expected to have WiFi only
So far I understood that EOS 4.2.2 had a USSD mod to activate the telephony function. That means to me the device did not receive calls without this mod. Did something fundamentally change to the telephony implementation in Android versions >4.2.2 or is there a similiar way to deactivate it in CM/OMNIROM? I think they made changes to the framework-res.
Please do not understand this question as a request to the community to program something, but I would like to know if there is a chance to get it fixed (even with some or much learning effort )
Regards

[Q] Possible problem with how Android handles Phone Dialing Codes (i.e. *82)??

Hi All
Sorry if this has been covered elsewhere or fixed, I couldn't find anything that covered this exact problem hence the post.
Also apologies in advance, this is gonna be a little long...
A little History:
====
I use my cell phone for both work and personal since I own my own business. I really hated having clients or potential clients knowing my direct cell phone number when calling them.
While I could program all of them into my cell with a *82 in front to block the caller id, I decided to go the other way so I wouldn't have to remember to do it on manually dialed calls.
Thus at my request, AT&T several years ago changed my network ANI default setting from "Allowed" to "Blocked" meaning by default, my caller id info is blocked when I dial, unless I put *82 in front of the number to override.
People in my phone book that I wanted my number unblocked for, I simply put *82 in front of their stored number.
At the time I did this I had a Blackberry Curve and all worked fine. I could call _AND_ SMS/TXT/MMS as normal - important to note.
Recently I got an Atrix 4g running Android 2.2 (now rooted). All was good until I tried SMS'ing a number in my phone book. Turns out the SMS app (default android app) does not like the *82 in front of the number. Instead of recognizing *82 as a valid ANI control code and thus ignoring/passing it, it thinks it is part of the actual phone number and errors out.
So now I have to have two numbers entered into every entry in my phone book that I want to be able to SMS or call without my number being blocked by default. One entry with *82 in front of it to call them unblocked and one entry without the *82 to be able to SMS them.
Anyone have any ideas how to get around this? As I see it it's something that either Motorola or the Android developers need to fix, i.e. telling the SMS app to ignore/pass valid ANI control codes.
Thanks in advance

Is this the standard android text messaging app?
What country and carrier as well?

Tmo Gtab 7.0+ WANT to keep but MUST return due to inadvertent calls to dead number

Greetings fellow G-tabbers,
I appreciate everyone's input here and am hoping to be a long-term member of this community.
I would love to keep this tablet but am thinking it's going to have to be returned before my 14 day window with T-Mobile is up.
My questions: Is it possible to set up some kind of workaround to be able to receive CONDITIONALLY FORWARDED calls via the G-Tab/T-Mobile phone number to my other T-Mobile phone (basically, set up conditional call forwarding)? According to T-Mobile they can't because the tablet plan has a code in the system blocking calls.
Or if that's not possible, is there some other way, perhaps spoofing my own cell phone number as my outbound text number instead of using the assigned tablet phone number?
I realize that there are 3rd party apps out there but I'd much rather use the native text messaging application and not a 3rd party app such as Google Voice, Line 2, etc.
Here's the background:
I am a headhunter for a Federal DoD contractor and as such, I review resumes on various job boards (i.e. Monster.com, etc). As a way to connecting with candidates (I know who they are but they do not know me yet), I send them a text message, email and then voicemail. When setting up my Data Plan, I learned T-Mobile scripted within the system "call block" or "voice barred" feature, Tier 3 tech support at Tmo is unable to set up conditional call forwarding.
As a result of this, should a candidate decide to call my text number they'll get a dead number message saying something to the effect that this phone line cannot take incoming calls.
So what happens is that the candidate things I am unreachable or worse yet that the text message was spam (unless they fully read their text and check their email account).
Thanks so much in advance for your help and consideration.
Im assuming you have a GT-P6200 since tmobiles GTab+ doesnt have phone abilities.
Tell them you dont want/need a tablet plan becuase YOU DONT HAVE A TABLET!
tell them it IS a smartphone, have them try to put you on a smartphone plan, thats
how most of ATT guys sneak by.
at least try to find a smartphone SIM with data/voice to see if it works without issues. It should.
last resort: "bribe" a young tmobile rep to spoof an IMEI to put you on smartphone plan.
Thanks Chris! I'll try that! I am using 2 other phones (work + personal), I wonder if I set up call forwarding prior to swapping SIM cards if it'll work.
Your thoughts?
Yes i think the call forwarding should stickt

Great!
I just realized that my mini Sims won't work. Have to buy an adaptor to try/test out.
Quick question... Only because I am new to Tmo and sim cards (just fired Sprint) . What is involved with spoofing an IMEI?
Thank you again for your help!
P.S. how do you use your tab? Do you have it rooted?
V/r.
I think other people here use smartphone sims with unlimited data on tmobile. Its do-able. Next time, a good rule is to always avoid telling your carrier how you will use your device because you know they think they know what is best.
Anyways spoofing an IMEI, means.. they need a smartphone IMEI in their "system", so a friendly helpful tmobile rep who doesnt care much about getting in trouble or knows his way around takes an IMEI from a never used phone like a demo model, you run an application that reports your IMEI the demo, etc. Its actually probably more involved than this. And Ive heard it may well be illegal, Class C felony. What you might want to ask them is if there is a way to just enter your device as a smartphone and not a tablet, but it is probably generated by IMEI.
PROTIP: if you do have 6200, it's good idea to make 2 backups of your /efs folder (if rooted).

Google Voice is not a 3rd party app, it will completely and natively integrate with your Android stock dialer. If you were on an iOS device it would be terribly clumsy, but not on Android.

There is no stock android dialer in Honeycomb as it was meant only for tablets and not phones. I thought I saw a thread somewhere in here of people using Google Voice with a third party app to make calls. I think you could also use the Goolge Voice number for texting as there were threads on how to do this in my phones forum when Google Voice first came out. I think Skype will also assign you a static phone number to use if you pay for the service. I would also search the other tabs forums to see if anyone in those has a mod for it to work as a phone off a sim card from a carrier. Personally I would trade it in for the Galaxy Note if I wanted to use it as a phone and tablet.
or check out GrooveIP in play store one of the more popular VOIP/SIP applications, has option for 3G, cant guarantee quality will be the same as regular voice, but Im sure its one of the top 3 out there.
After doing some Googleing and reading up on some GTab 10.1 threads it appears that Honeycomb 3.2 on a GSM tablet should be able to make calls if the carrier supports it. Which TMO doesn't. You could try getting a pre-paid sim card and dropping it in to see if it will work, maybe something like Virgin Mobile. There maybe something in the OS from TMO that may block other sims so not sure how that would work.
After thinking about it the tablet is more than likely locked to TMo and it has to be moded to use anohter carrier, like boost mobile. For phones its a complicated hack getting it on another network. I still think your better off getting the Galaxy Note but then you would have to pay for a second phone line and data plan to use both the tablet and your phone at the same time and then conditionally forward your calls as you suggested.
Hi,
I'm not interested in using my tab to make calls; only to send texts via the native in-built messaging app. I don't want to use other Android apps, just the stock messaging. I am able to do this to great success on Sprint. Sprint is able to go into the backend system and apply conditional call forwarding. Not the case with Tmo.
My main purpose is to NOT miss calls from people who may decide to call via reply to text as that's what appears as my callback number when it's not.
Thanks so much to everyone for your input.

Sorry to say, but TMO won't support this. They have silly notion that you should buy a separate phone from them if you want to make calls.
still not sure what device you have. this may be worth a shot, although I understand tmobile says its not possible, etc.

what is wrong with other messaging apps?, there are usually many on the market which have many more options than stock. just asking.

Hi,
Don't want/need to make calls. I only need for texting, however, if one of my candidate prospects (I am unknown to them at this point) attempts to call me via the link on their phone because of my text from the tablet, it'll ring to a dead number, the tablet number.
I ONLY want the calls to be conditionally call forwarded to my other Tmo cell phone which already has unlimited phone minutes.

Hi Chris,
The reason I don't want to use other apps is if/when we move to ICS some of those apps may not be compatible for some time until they upgrade. I was burned using a VOIP app (Line 2) which worked very well and suited my needs on my older Gingerbread Tab (HTC EVO View) and when I upgraded to HoneyComb I learned that Line2 won't and never will support HC and I now know that the EVO View tab will not be upgraded to ICS.
I don't want to go there anymore, it severely impacts my ability to get my work done. I'd much rather use the native messaging app. Also because it doesn't use any data to use the native app, if I use an app from the Play Market, I'm likely going to have to use up my data plan and then I am prone to crashing, etc. Unless I am missing something are there any other alternatives?
V/r.
Two options:
(1) Sign up for GoogleVoice and port your number to that. This is very easy and will give you full control over where that phone call routes.
(2) Go get a straighttalk SIM ($15) and service ($45, for unlimited) and tell TMO they've lost your business.
Or, do both.

Is is truly unbelievable to me that in this day and age such an essential phone function could have been overlooked! I have been searching for days and days and found NOTHING or got stupid responses such as "use Google" (Online only, uses Data and for US Citizens only) or "use voicemail" (expensive cellular provider subscription add-on)... I mean, come on! When even the cheapest home phones can be gotten with built in answering machines, how come this essential feature is nowhere to be seen on android phones?
What's the deal, what's the technical hangup, what's the problem? Can anyone explain the REASON why there are NO call answering machine-like apps of any kind out there?

Im looking for the same thing and can't find it too!
Here is my need. I have a business phone number and my personal cell phone number. All my customers should call me to my business number which I can set to auto-forward to my cell only at the time I want to. But some of my customers know my cell phone number and they keep having this bad habit of calling me on it instead of my business phone number.
I'm looking for a app that will be tracking in the background the caller id number of incoming calls, if the number is a on list of unwanted that I have set, it will auto-answer, play an audio file recorded by me (like: "Please dial 111-222-3333 to reach me, thanks you") and then hang-up.
I don't feel alone with the need of a solution like this. And there are apps that can auto-answer call according to the caller id and there are apps that can play audio in a call, I don't see why it could not be technically possible to combine both.
wow
can't belive it, i was looking for the same and found several threads like this one, that's sad
let's hope sth comes up
Yeah, I used to have this function on my old fliphone from way back in 2002! Also, on my Windows Mobile phones after that...
Exactly. My nokia flip from ages ago (ran symbian OS) has an app on it called "Advanced Answering Machine" or "Advanced Call Manager" or something similar.
I could set it up so that it would direct calls to different greetings depending on the caller ID. An example of this is, I wont accept calls from "unknown" or "blocked" etc numbers. ACM/AAM would handle this perfectly. It would answer the phone, play the Telstra (thats a telco in australia) message "the number you have called is not available from this service." twice, then hang up. Later on I found out I was missing some important calls (the message confused some people such as the landlord who had a blocked number) so I changed it to "I do not accept calls from blocked numbers. To unblock your number, dial 1831 in front of your number. It wont cost you any more". This fixed the problem.
It was also programmed to answer calls after 30 seconds of ringing and play a standard greeting then take a message.
It was a very versatile program. I could (for example) divert certain calls to a party line if I didnt want calls from that particular number; however I didnt, as the diverted leg would cost me a fortune.
Its a shame on these advanced handsets today that such a simple, commonly available on landline phones, feature is not available. I can control televisions, fly remote controlled toys and vapourize components with a big bank of capacitors over bluetooth using my phone, yet it cant perform a simple answering machine function.
From what I hear the API that handles these functions is not directly accessable to developers; probably because "malware" could hook in and dial high priced premium calls and rack up huge bills all the while the phone owner not knowing until the monthly account comes in.
I did see one answerphone somewhere but it utilised the speaker so if it took a call (for example while your at the pub) the caller would not hear your greeting, or on the train everyone around you would hear your greeting and then the callers message, so not very practical. It would NOT work properly while the phone was on mute.
xperia phones come with buit-in answering machine feature. or use jail broken iphone and u have half a dozen apps which can do it.
unfortunately in android noway.. even if u r rooted.. no way

[Q] 3-way calling solution with flash or simple root

The Samsung Galaxy III with Verizon (same with any Samsung on Verizon) won't allow you to release the second party once you merged 2 calls. It also won't allow you to initiate another 3-way call, even if one of the people in your conference hung up and you're only connected to one person.
Once you merged 2 calls, your only option is to end the call which will end both calls.
Samsung on AT&T and TMobile do have the option very easily on-screen.
Though in many forums people suggest its a CDMA versus GSM issue, its not, as all Verizon 4G phones are on the CDMA network and it can be done on other brands like Motorola,
(Tho it's not an on-screen quick option on the Motorola, do the following after you merged the 2 calls: click home, people/contacts, tiny phone icon at the bottom, and then the green phone icon, which disconnects second party without ending the entire call and you can then even initiate another 3-way call). On any Samsung with Verizon, this option wont work. The combination of Samsung and Verizon have eliminated the good old "send" feature that lets you hang up the third party plus have your phone free to continue making another conference call.
I've read somewhere it can be done by doing the following:
"Root your phone and flash cm9 or 10, The dialer on this rom will allow it" (from reading many many posts, i don't feel too happy with trying cm10). (I'm not even sure if he meant i would stil need a special dialer or once its rooted the phones dialer will let me hang up the second party and/or make another conference call)
Has anyone tried solving this problem with rooting successfully? (or any other method), if so please specify what ROM etc, I'm a newbie but relying a lot on 3-way calling. maybe I'm too naive and rooting alone even without flashing would solve this?

I'd love to know as well, I'm having the same issue on my Verizon Galaxy S3. Like you said, the Razr HD can do this with no problem, and every other s3 and note 2. Whats the deal? Can the dialer be added from anther carrier phone? Will the AOSP dialer do the job?

some phone callers are always reaching disconnected message to my phone

I am looking for some information regarding a problem I am experiencing with my phone, I have 3 questions regarding it. I have stated them at the end of this lengthy post.
My phone is zte grand x2 model z850 and android build is 5.1, carrier is pcmobile in Canada.
The problem is that my android phone seems to work OK and receives calls correctly, but my doctor office, hospial booking office, and phones belonging to my workplace receive a tone followed by some type of reaching a disconnected number. My phone calling log shows no record of calls being received to phone.
The troubleshooting steps are sent email to pcmobile and received response to do a battery reset, pull out battery and sim card for at least one minute and reinstall. If it doesn't work call their customer support and get put through to tech support.
That did not work. Call to the tech support says that all 0:00 second calls end in response to some type of code (mentioned a specific code but I forget) and that it means my phone is responsible. She said android phones allow for rejecting calls based on various categories like toll free originating and such. And that the phones calls not getting through likely belong to a category I have blocked. She mentions just goto phone menu, settings, and something like call block, call reject and I will most likely find something there. If that doesn't work to do a backup and factory reset. To do that she says I need to call zte for help as she isn't allowed to help with it.
My zte phone interface only shows call barring settings with a few things like all incoming or incoming roaming, outgoing or outgoing roaming and that is it.
However it is possible that I came across via a web search a USSD code to ban telemarketers and used it. I just don't no what code it was or even if I did such a thing.
Anyway I called back their customer service to maybe get further help and had specific phone numbers and times of calls that were rejected by disconnected number messages from my workplace. To see if the problem could be isolated at my phone as a reason or maybe in the network somewhere. And was also wanting to know how I can unset the call reject if I have no interface to do it or undo it. Maybe even get confirmation that the noted calls are actually making it to my phone or getting dropped in the network. The new customer support first asked if it was a ported number and since it was, he checked with someone to see if it was a problem. The porting people said all calls were routed correctly through to my phone, but the customer support guy said there was no way to verify if my specific noted calls were included.
He mentions their tech support did not help with actual phone troubles, but he suggested I get another sim card and phone and use them in varios combinations with my phone and sim to get the working/ not working situations and isolate the problem. This I have not done yet as it seems like a lot of expense and jumping through hoops trying to fix a problem that seems like it should be able to be verified in a phone setting log somehow. He refused to put me through to tech support when I said I wanted him to anyway.
My emails with zte have them requesting I do a backup and factory reset, if that doesn't work then try a new sim card, if that doesn't work then book my phone for a repair with them.
So my question number 1 is:
Is there a USSD code that allows me to see settings or logs of such a call reject being used. I have tried *35**# which is supposed to show "incoming call barring" and it responds "Call barring Service has been disabled." My phone user interface doesn't provide for this as best as I can tell.
My question number 2 is:
What is the USSD code that I might have used to try and reject telemarketers which might issue tones that might indicate a disconnected number. I'm thinking this is the most likely reason for my troubles. I have been unsuccessful google searching for what I may have done. I find info on various USSD codes at this forum and elsewhere. But I'm not finding anything specific to help. I thought the *35**# would have helped but it doesn't. It is very possible I did do something like this with a USSD code which is causing my trouble.
.
Part 2 of this question is what would be the USSD codes to see the status or to unset such a thing.
My question number 3:
If there is no way to set status or see the status of call barring and rejecting logs or settings of the phone. If I do a phone reset, how is it possible that it could be the sim card instead. Does the sim card actually store call rejecting and barring settings as well.
Part of troubleshooting this involves me contacting third parties such as work, doctor, or hospital and asking them to try and call me and if not successful contact me someway else and tell me it was unsuccessful. I really doubt any of them want to do this for me more than once or twice. So I'm trying to gather info and limit my number of attempts. It would be real useful to be able to look up logs or settings somehow.
Would anyone know if the effect of *77 being used is that the caller experiences reaching a disconnected number. Or what do they usually experience.
In web searching possible codes I may have used, I came across the *77 code to reject anonymous callers. The *87 would be to unreject such a setting. Is there a method to check the current setting of either on or off somehow.
I am unable to test the specific phones getting the message of reaching a disconnected number. I will however have better access to one of the phones in three weeks time to see if *87 fixes my troubles.
