Turn 3G off Samsung Jack - Non-Touchscreen Windows Mobile Other

I used to have the Samsung Blackjack II and I could turn off 3G, which conserved battery life. I called AT&T, who called Samsung, and the lady told me that there's no way (as of yet) to turn off 3G. I'm sure there is, but I haven't been able to find it yet. Does anyone know of a way? Any help would be greatly appreciated!

open the setting>phone>all calls>band selection>900/1800

I don't have Band Selection under All Calls.
Here's what I have under All Calls:
Call Options
Caller ID
Channels
Fixed Dialing
Networks
I guess I forgot to mention that I have the Samsung Jack, not the Samsung Blackjack II. Sorry!
Thanks for the post back!

[Q] can't make phone calls galaxy tab 7.0 plus

Every thing i'm reading says you can make phone calls from the galaxy tab plus in receiver mode. is that strictly for the 3G versions? Because on my wifi version I don't have that option.
Sorry but off course you cannot do that with WiFi version...only 3G works as a phone.

That's only half-correct. You can't make phone calls without a wifi connection in the wifi-only version, and it is missing a traditional dialer, but there are plenty of apps, such as Skype, Vonage, and GrooVe IP which will allow you to make calls in receiver mode even on the wifi-only version.
Does anyone know if the 3G/4G GT 7.0 Plus can be flashed to enable voice calls, like the original Galaxy Tab? Thanks to the great devs here on XDA I was able to flash my original tab & was hoping to do the same if/when an AT&T model is released. Other web sites (samsung, gsm arena) show pics of the GT 7 Plus & the GT 2 with the dialer app. I'm sure these are the European versions, as was the case with the original Galaxy Tab.
....if not, I may have to settle for a Galaxy Note.

I understood we were talking about phone function with dialer application, which wifi version is unable to offer. And off course there are plenty devices which are able to make calls through VOIP, Skype etc...but not through GSM if there is only wifi version. This is general for tablets and computers.
Does this the t869 version have the "Voice Receiver" mode?
Talked about on the Samsung site or just speakerphone?
samsung.com/global/microsite/galaxytab/7.0/feature.html
No it does not. Tmobile variant is missing some hardware = crippled.
Sorry guys so does the 3g model work as a fully functional phone on T-Mobile?

Or does any version run on T-Mobile US 3g that can be used as a fully functional phone?

That is the million dollar question that I am trying to get answered too. I have the original Samsung Galaxy Tab and make phone calls all day long with it. Of course I am using a SIM that originally worked on a Samsung Galaxy S so I don't have just data on my plan.
If you are like me, you are absolutely frustrated that you can either have Phone+2G or swap modems and boot into pure 3G mode without phone calling ability. So, I have a couple people confirming that the Huawei Springboard can make phone calls and I believe also utilize 3G/4G on the TMobile USA network (unconfirmed on the 3G/4G portion). I want to stick to having a 7" device that makes phone calls as my phone but I want my 3G/4G ability that I am paying for.
So, here are the tablets that are out and if they work with TMobile USA network:
Huawei Springboard Phone=Yes, 3G/4G=?
Samsung Galaxy Tab Plus Phone=?
Samsung Galaxy Tab 7.7 Phone=Yes according to one website
Samsung Galaxy Note Phone=No, not unless new radio is put in unit.
Dell Streak 7" - Not sure
Thoughts? Errors that you see on my info above?
From what I understand the Springboard is also missing the hardware to do voice calls without Bluetooth, speakerphone etc.
Is it possible to purchase the int'l unlocked version of the Galaxy Tab 7+ that has the voice receiver hardware and flash the modem, etc from the T-Mobile version so that tmo 3G/4G?
Or is that a hardware incompatibility with the int'l version?
Juanpv, I believe you are right about the Springboard not having the hardware/microphone to handle phone calls without bluetooth or headset.
I believe the international version of the Tab Plus doesn't do the 1700 bandwidth which the TMobile USA network needs.
I'm so frustrated right now. Does anyone know of a 7" device that works on the TMO USA network and allows phone, 3G/4G without having to reboot?
I've been using the T-Mobile galaxy plus as my primary phone for about a month now. I etf'ed(if that's not a real word,it should become one) my original number to transfer it over it Google voice,only cuz i picked up a galaxy ii as well. I downloaded the groove IP app and that was pretty much that. Now granted,its not ideal,on wifi u get a small delay,and because I live in a market without 4g...its almost impossible to use it as it cuts out either when I'm talking...or the other person on a line. My tablet has two numbers attached to it also...the Google voice one and the T-Mobile data plan. Granted...I use really only about thirty minute a month for voice...its been pretty ideal for me. It was also very easy to attach a blue tooth headset to it. Also,I don't think it allows u to call 911...but with two other cell phones in the house,I hope it wouldn't b a problem. So I've been pretty happy with this setup..playing games is great, I've been reading way more then before and I have yet to find pants that I own that it doesn't fit in....watching Netflix or other movies is great,especially on the treadmill ...and that'd really when it becomes awkward...is listening to music at the gym...but its cool to use apps like jetfit pro to keep track of your sets. Is it ideal...no...but more then functional. Let me know if anyone has any questions.
Ps. While the camera takes decent pictures...its def a drop off from the quality of the s ii I got use to before I gave it to a family member.

Thank you for sharing in what way you are using the TMO Galaxy Tab Plus. Have you tried or found any hacks to get one of the sim cards, from another phone, to utilize the phone features of the tablet?
I see on the Samsung website that it has phone calling capabilities but I also read somewhere/someone believes TMO had Samsung remove the physical hardware to support standard phone calls. I personally believe that is erroneous information as they thought the same with the original Samsung Tab.
I am just using another "data" sim card from T-Mobile...so I have two numbers attached to my tablet ...sorry...I did scour the interweb to find a trick to just use my original one...but no dice :-(

From what I have gathered, and excuse me if this has already been said (It doesn't look like it above)...
Galaxy Tab 7 Plus (USA Version) won't allow 3G/GSM Calling. No one has hacked it like you can on the original tab. I actually bought the Galaxy 7 Tab Plus in hopes I can, and sadly found out after hours of reading that I can' t
Now, the Galaxy Tab 7 Plus (International Version) does allow you to! It will run you around $700 for it (I was able to find one for $460 in Australia, but shipping is expensive).
The reason the USA version can't, is the same reason why no tablet in the USA can make calls the carrier (I believe) blocks it. I don't know exactly why they do, perhaps data usage or something... there is only 1 or 2 tablets out there that support gsm calling, I don't recall what they are though, but nothing fancy like a Galaxy Tab 7 Plus.
I'm all about GSM Calling and anti-VOIP calling, but as I do more research I might migrate to VOIP phones, mostly because there is no limitation on what device you use...And I'm leaning towards the Sony Tablet P (Fold/Clamshell design)... I know, 99% of people out there hate that device, but I love the idea. Comes out in a week, so I'm pretty excited
Hi NineT9, having used cell phones in a dozen countries while living there, I can assure you that in US, cell because just sodomize you and take fortune out of your pocket for that matter.

Is that possible on T869? Like installing a rooted EU rom on T869
So that I can retire my G2 on eBay
Hey I am getting plus on Friday I will use my G2 sim in it and post you guys how the VOIP stuff goes
Last edited by jijus; 29th February 2012 at 10:53 AM. Reason: plus
I was under the impression that I could use my G2 sim which has unlimited data on this Tab, but that not the case!
TMO wants me to sign up for another data plan, so said KMB and send the damn thing back. As I could only load T-Mobile website on it using my sim card.
Now I am ordering EU tab thru my friend who lives in London. I will post updates after getting it

See, I feel differently about utilizing VOIP or relying on it. I personally have been using VOIP on older Windows Mobile devices, Nokia N800 and my Samsung Galaxy Tab when in 3G mode. But, I can tell you it's like having cell phone access about 1/10th of the time that you would have Cellular phone ability. Maybe it's even less but I don't want to be too critical. The amount of dropped calls, weird echoes, inability to even call, etc. is just too frustrating to rely on for a day to day phone. Plus, you'll upset everyone that you are talking too because they suffer through the same problems as you do. It's been a great way to alienate my friends.
I think I'm going to have to just give up and go back to a dumb 4"+ phone just so I have a dual core, Cellular, 2G/3G/4G capability all at the same time SINGLE device.
Damn the US phone companies! Every last one of them. At least with T-Mobile's business plan I get 1000 minutes, unlimited data (5GB), unlimited text for $39.99 a month. If I wanted unlimited everything then it's just $10 more at $49.99 as of Feb 2012.

Wow, thanks for that post I've been asking numerous people and read a few threads/articles online about VOIP, and what you said is exactly what I was afraid of, and I've been told it won't happen if you have a connection... but I thought, well what if I'm driving? That means the speed will only decrease drastically, and like most people I talk while driving a lot...
I was afraid of the dropped calls, echos, upsetting the other end, etc etc... looks like that will happen still
Sadly, I think I will also have to go back to a dumb 4" phone too :\ I really want to use the new Galaxy Tab 7 Plus as a phone, shame it's not possible like the original :\

[Q] Wi-Fi calling Sprint S5

My S3 died last week and was replaced by the S5. I am in a Spark area and so far am impressed. My issue is that I have been using the Airave to make and receive calls @ home and the office - figures, the 2 places where I spend most of my time there is literally no service. The Airave sorted that. UNTIL, the S5... 4G/Spark isn't compatible with the S5. Unless, I manually switch my phone to 3G. It's not that big of a deal, but it is one more thing to do. The Airave tech support told me that I needed to get the WiFi Calling app. It wasn't on my stock build when I purchased the phone. I did receive an update within a few days, but that didnt have the feature. Sprint told me that an update was coming that offered this feature but didn't know when. I really don't want to wait for months.
Can anyone post/send me the wi-fi calling apk that will work with this thing?? I really dont want to root and rom this handset.
Thanks in advance!

S3 -> S5 also with poor signal at home. I have Sprints Airvana for a year now. S5 works just fine right out of the box, did nothing. Without the Airvana I have to be upstairs, stand on a chair and hold the phone up in the air to get any signal at all.
You could try and go into settings/network connections/more networks/mobile networks and change to auto in network mode

Yes, That's what I have to do now. But, I have to remember to do it. I'm not so bright sometimes. Then I have to remember to turn it off when I leave so that I can take advantage of the Spark service in my area. It would be so much easier to remove the Airave and simply activate the wi-fi calling feature.

DO NOT LEAVE IT IN "AUTO".
You will be UNABLE TO CONNECT TO THE AIRAVE unless your are in "CDMA ONLY".
Go to
settings/network connections/more networks/mobile networks
and change to CDMA .
( Do NOT select CDMA/LTE until you LEAVE the Airave vicinity)
If you are indeed connected to the Airave, you will hear a recording telling you that you are if you call *99.
You will have to re-enable the CDMA/LTE everytime you leave the vicinity of the Airave to get LTE service.
Sprint Tier II Tech informed be of the above, and I have verified it all by personally testing the above.
Now, here is the real question:
What are the EXACT DIFFERENCES between using the "Wi-Fi Calling Feature" with NO Airave - AND- using the Airave WITHOUT using W-Fi Calling.????

Using the S2 3g without the 3g

I have a question that I have not been able to find the answer to. I want to purchase a s2 3g but use it as a wifi bluetooth watch. I want the bigger battery and gps. If i were to buy it from, say, amazon, would i have to activate it on the carrier to use it, or could i just use it just like the normal s2?

i believe the answer is no you do not need to activate it on the carrier but you will not be able to forward calls as far as i know.
Cool thanks. I don't want to call forward just want the watch.
It'll work fine thru Bluetooth as long as call forwarding isn't turn when you set it up. As long as you don't turn that on should be golden

Works fine.
I've got the 3g AT&T version. Check Best Buy site, Found mine with No contract for $149.00! (Yes I think it was a error on the site!) Anywho, the watch gives you the option to set up the phone number but without the SIM being active it will not save the settings. Everything else works fine via the bluetooth connection including the speaker-"phone" from the watch during calls.
I really like it, but kinda miss my gear live... just wish tinzen played better with android like my gear live did.

S4 lte goes off just to receive calls (had same problem on S3)

Have a very weird problem, and think it is because of any app...
I use a galaxy tab s4 lte as a phone, it is a fully functional phone oversized... it is great, and im using tablest as phone 3 or 4 years ago... first was galaxy tab s2 lte, then s3, and now s4
S2 worked great... S3 worked great but from march of this year, randomly phone disconects fron network just to receive calls.... sms, 4g and wifi always work, but canr receive calls till i make a call... it is like it disconnects from network... i notice that, because i have (from the times of s2) my phone forwarding calls to my wife's phone when my phone is turned off or im in a plane for example...
But with tab se, from march, i was in home with my wife and someone that call me ringed directly to my wife phone... a lot of times saw that... but when i place a call... it start receiving calls again...
Went to tmobile, changed the sim and same problem...
Bought a new S4 lte ($1000) and from the day 1 same problem...
Any help? Im pretty sure it could be any app... but dont know where to start

Did you by chance put it on LTE-only mode? Where it does not receive calls there is some network configuration problem or lack of Volte when it automatically switches to 4g.

Help! Our "unlocked" Sprint Galaxy 7's won't do wifi calling with our new provider!

Help! Our "unlocked" Sprint Galaxy 7's won't do wifi calling with our new provider!
We have 2 Sprint Galaxy S7's, GSM-930P. Never set up wifi calling on sprint but had an icon for it and they were always asking me to set it up. Switched to Mint mobile which works on Tmobile's network. When on wifi at home or work can't send or receive MMS, pictures, but turn wifi off and the pictures go or download. Never had this problem before. Have wifi turned on through our provider and there is a greyed out wifi callng icon at the top of screens next to signal strength and wifi icon.
They say I have to turn it on in our phones for it to work properly but that setting isn't in any of our menus. I've found other threads talking about it being gone on sprint phones but the phone is capable of wifi calling from what I've found. I found one post somewhere about someone "flashing" their phone with the tmobile software or something and it working. On Mint mobile's site they have a list of compatible phones and our IMEI isn't listed as being compatible? It's so confusing and frustrating. I know these phones are capable of wifi calling and think that it would make our phones work better if we changed some things up. I'm trying to figure all of this out but not sure how to do it or who to listen to online. I would appreciate any help you could offer. Thank you!
