cannot leave voicemail when calling to other's people phone even in the same network

[Thienhuy]

Hi all, just wonder if anyone encounter issue with calling other's people and when they're not pickup, it does not connect to their voice mail?
I'm with AT&T, when calling to my friend with T-Mobil, I'm not able to leave a voicemail to them since the last update in end of July-2016.
Trying to test with same network (AT&T) it only work with Iphone 6 or other Galaxy but not Iphone-5s or below.

Any advise/thought would be appreciated.

Thanks,
TH

(I have galaxy s7, version 6.01 with AT&T carrier)

Welcome to Android Central! Does this happen with more than one friend on T-Mobile? It sounds like it's more of an issue with their voicemail setup, or with the T-Mobile network. I doubt it would be an issue with your phone.

It does happened with other T-Mobile also (different phone and model). it does not work even with the same account with AT&T (it worked OK with AT&T galaxy phone and iphone 6) but not with Iphone 5S same account.
It works fine before the update recently in the end of July. I called AT&T and they don't know how to fix it, they called Samsung factory and all they suggested is go to Best Buy and ask them to re-flash the phone (down grade to the previous version that worked).
I'm surprise nobody using galaxy s7 having the same issue yet with the new updated
Oh by the way, my co-worker has the same issue like mine, he has S7 also.

I found the fix while searching this morning:
https://forums.att.com/t5/Samsung-Discussion-Support/I-can-t-reach-other-people-s-voicemail-to-leave-a-message/td-p/4901258

Just got the issue resolved. Here's what i had to do;
SETTINGS
MOBILE NETWORKS
MOBILE DATA
uncheck Enhanced LTE Services

They are having issues with this service

I wish AT&T support told me this or I found the work around earlier so I don't have to do a Factory data reset twice.

Good detective work! Thanks for sharing the solution.

My wife was having this same problem and it was driving her nuts! We discovered that there was no problem when calling another Samsung phone or iPhone, but when calling my LG or a Motorola phone, the Galaxy S7 would act like the call was connected but would not connect to voice mail. We had tried everything to fix the problem, even doing a factory reset on her phone.

Thank you!

On my Samsung Galaxy A20 phone, I fixed not being able to leave a voicemail message this way:

Go to: SETTINGS/ CONNECTIONS/ MOBILE NETWORKS/ NETWORK MODE. Click on "LTE/3G/2G (auto connect)"
