[Q] LTE doesn't work on SM-N915FY

Hey guys.
I have an issue with my Galaxy Note Edge SM-N915FY. I got an LTE SIM Card from my provider two months ago. In this time I haven't seen the LTE symbol in the notification bar. It just says H+. Is there any way to get the device using LTE? LTE is activated from the provider and in settings of the device. My SIM card works fine using LTE in other smartphones like S4 Mini and another Note Edge. Just my own device is stuck with H+...
My SM-N915FY is complete original and it's running Android 5.1.1 and I live in germany.
If anyone has any advice for me, you would save my life!
network -> apply LTE-WCDMA-GSM, i sm-n915fy italy but work in LTE

So I bought this Samsung Galaxy S6 Duos (Unlocked) [SM-G920FD] from Swappa but can't seem to get it work with T-Mobile at all! I'm hardly getting any bars plus network keeps dropping off. Funny thing is I live in a T-Mo zone, my other phones (running on T-Mo) work without any issues. No Problem with LTE either.
I'm super frustrated and donno what to do anymore.
What apn setting do I need to use? I will really appreciate it if anyone can kindly help me out with detailed instructions, since I'm a such a dumbo!
Thanks in advance

Duos g920FD is same geographical version as international g920F (except it is single SIM), same 3g and LTE freqs.
There is a T - Mobile version for s6 (g920T), only single sim, there is not duos t - mobile version.
It means probably your carrier is using 3G 1700MHz freq on your zone, the only additional frequency that g920T has and g920F/FD hasn't. Both versions have same LTE freqs except F/FD versions has 3 more LTE frequencies available, because this you have not problems with LTE.
Check with your carrier if they are using 1700MHz 3G band and if so, sorry, you should change any of your carrier or your phone, or force GSM connections. Or maybe you can also configure your duos s6 using a non T-Mobile SIM for data 3G/LTE, and your T-moblie SIM as 2G (GSM) only voice/SMS.

4G Super voice (VOLTE) activation

hi im in the uk using the note 5 n920p. Im currently using the MOAR rom does anyone no if there is a way to activate 4g volte option as i dont see it. my network coverage in my area is poor and my network provider has said that i need a phone that can use 4g super voice(volte) to get coverage in my area. i did some googling and apparently the option for this can be activated on the other note 5s but im having trouble finding how to do this on the sprint varient.. does anyone know if this even possible?

Spring Galaxy Note 5 Signal Issues

Hi guys,
I'm using Sprint Note 5 N920P with my local sim card Ufone and its working perfectly fine except one problem. My network signals fall rapidly at times and I've been having this issue since the beginning.
Can anyone tell me how can I fix this? I'm in Pakistan and the firmware's CSC code is TGY. Could this be a CSC related issue? Should I flash my country's CSC?
Thanks.

WiFi calling on SM-G930W8 (Canada version) s7 with Cricket cellplan

I have an unlocked SM-G930W8 (Canada version) s7, and I would like to do WiFi calling using Cricket as my carrier. Is that possible?
The Cricket website says:
"Note:*If you did not purchase your phone from Cricket but it is Wi-Fi Calling capable, you can still use your phone but Wi-Fi Calling will not work."
Cricket does not include the s7 in their list of WiFi calling capable phones. I was thinking one possible solution is to flash it with AT&T firmware because AT&T includes Wi-Fi calling on their s7's. Would that work?
