Gsm band fix - Galaxy S 5 Developer Discussion [Developers Only]

Does anyone has knowledge about adding all gsm bands to Galaxy S5 g900f? When I switch to GSM only , I cant make calls and send or recieve sms ,I cant use mobile data ...

i'd search APN'S

That sounds like a problem besides GSM bands, hard to tell without more information. Here is a resource on adding them, though.

[Q] Can I make calls on the SM-T217S??

Hello,
I have searched throughly for my questions but didn't find anything unfortunately...
Will the tab 3 SM-T217S be able to make calls? I am talking regular calls not using apps that use data.
I live in a country where there is CDMA network provider and heard that there is no dialer on this tab which is important for me to programme the tab into my country's CDMA network provider.
I also came across a forum where it said the call functionality is there in the tab 3 but sprint has blocked it because the will only give you a plan with data not voice, so does that mean that if the SM-T217S gets programmed to another CDMA provider the call functionality can work normally??
I appreciate any help guys and thanks in advance!

Hey, i was about to purchase this to flash to IUSACELL Mexico, but instead went with the ATT version with SIM card because i have a better data plan with GSM provider than CDMA provider.
But i did some research prior going with the gsm tablet, and it appears you can flash it with DFS cdma soft, and of course if the new plan has DATA/VOICE it should work like a phone and sms and all that, providing you download a dialer and use an external hands free headset (i dont think it has a speaker like the GT3 8").
You wont find much information, all has to be done with trial and error.

Can't recieve incoming calls our call out unless on EDGE

I have just received an i747 from a friend and had unlocked it to be able to use my T-Mobile SIM. Now the phone works but I cannot call out OR receive calls unless the phone is on EDGE. If it has a 3g connection I cannot call out or receive calls for some strange reason. When I try to call out it will not ring and hang up after about 20-30secs. I can also not if I turn the data off completely.
The IMEI does match the back off the device and i have system reset the device. I tried it while on: stock unrooted 4.1 / 4.4 , stock rooted 4.4 , and a custom rom (currently SlimKat). They all do the same thing.
Any fix for this would be great. My best guess is there is something wrong with my efs folder but everything seems to be there so I am not sure.
At the very least is there a way to disable 3g all together leaving only Edge and LTE? Although this is a last resort.
Thanks.
Edit: I forgot to mention that messaging and data connectivity work absolutely fine and I haven't had a problem with that.
Does T-mobile use AWS in your area? I read that AWS has to be renabled each time you start/restart the phone. The i747m (Canadian version) software doesn't natively support AWS.
if thats the case found this

Is there a chance the dropped calls could be due to an incorrect APN setting?
^^I thought APN settings affect data only and network type (gsm, wcdma) affect voice calls.

You're correct, once again I put mouth/fingers in motion before fully engaging brain. APN does control data, internet, mms, etc. I guess I was thinking AWS was related to data frequencies instead of voice frequencies.
^^ No worries. We're all here to learn from each other.

Sorry. I rarely use txt & MMS. I pretty much use Hangouts and Viber to chat with everyone I know.
By the way, if touch tone DTMF is not working, try to change the DTMF from Short to Long in Phone settings.
I have a T-Mobile edge and edge plus, both have band 12. One of the offices i work at only gets band 12.

Ofc the tmo S6 has band 12 support. I meant the verizon S6.

It's the same one that's everywhere online for TMO LTE, it's not device specific, in fact the same settings are used for all LTE enabled phones, even iPhones. I'd be shocked if it wasn't either the 1st or 2nd result after a Google search.
I once had Verizon Edge+, and used it on T-Mobile.
Add and use the following APN.
Name t-mobile US
apn
fast.-tmobile.com
mmsc http://mms.msg.eng.t-mobile/mms/wapenc
apn type default,supl,mms
Leave all other settings as is.
For MMS to work, make sure you add "mms" in APN Type field.
Moreover, once in a while, you'll get an annoying popup saying that the sim card is not Verizon etc. If rooted, just use Titanium Backup and freeze the "activation" apk. If not rooted, use Package Disabler Pro, and the disable the aforementioned apk.
Good luck.
the issue is in you are using Verizon S6 Edge+ on Tmobile network, you can't use data while on phone call.
it doesn't pickup band 12, only works on band 4 etc, which loose the data if phone call picked up.'
is there any way around?

My note 3 did this going from verizon to tmobile. A workaround i found was to switch the network settings from 4g or global to 3g or 2g only and then make the call. Touch tone would work, then after hanging up switch network settings back to 4g or global. Hope this helps you.

Question Problem to use Motorola Edge X30 in USA

Hello, first of all I want to say that my native language is Spanish and I am using the Google translator to write this, so there may be writing errors and apologize.
Buy a motorola edge x30 and the imported import from China. The phone is unlocked to be used with GSM networks from anywhere in the world. When I bought it, I was with Metro PCS but in Metro I was told that the phone was not compatible with the 3G networks of them. After that I started to investigate and find a web page called kimovil and there I saw that the edge x30 was compatible in the USA with all the networks of 3 suppliers: Cricket, AT & T and T-Mobile: I choose to use change to metro by T-Mobile.
Immediately I left the T-Mobile store after making the change I have tried and could receive and send SMS, receive and make calls, and get access to the Internet without any problem. After a couple of hours of having activated services with T-Mobile, the phone could not or receive more calls (the Internet and SMS continue to work normally, the problem is only with calls). When I try to call someone, the call is not done and says "Hanging Up". I tried everything: Factory Reset, Networks Reset, modify network configuration, everything ... and I can not solve the problem. I went to T-Mobile to tell you about my problem and they tell me that the problem is not them but my phone.
If anyone knows how to solve this problem, I would greatly appreciate the help because I feel frustrated. Thanks
I have MOTO EDGE x30 with T-Mobile. Work perfectly. Check the SIM setting.

Good afternoon. I already managed to use the Edge X30 with the T-Mobile network. You just had to put the network selector on automatic so that you can use 5G, LTE, 3G and 2G as you see fit. The problem is that I realized that the phone only calls and receives calls in 3G and 2G, which limits not only the quality of the calls but also limits your coverage to be able to make calls since you can only make them in 3G and 2G . You who also use T-Mobile, does the same thing happen to you?
I'm not sure, but it supports 5G in N1/N3/N5/N7/N8/N20/N28/N38/N41/N78 and 4G in B1/B2/B3/B4/B5/B7/B8/B12/B17/B34/B38/B39/B40/B41. or check volte settings.
you may try to install "carrier services" app by google from the play store. it solves some of my problem with data connection.

Yes I have the same issue. Whenever I make or receive voice calls, the phone falls back from LTE to 2G. I looked everywhere on the phone for 'VOLTE' settings but could not find it. Does VOLTE work for this phone on Tmobile? Very frustrating.
Has anyone been able to find the solution for the calls switching back to 2g? I love the phone but this is extremely annoying. I'm on T-mobile. Thank you
