Messenger, Viber and Skype not working on Data internet on Samsung Galaxy, why?

[AC Question]

My data internet is not working in messenger, skype, viber or watsapp. Please tell me what I should do, on wireless they work perfectly, I can send and receive the messages, but when I am trying to use my data internet it is not connecting. Facebook as an application it is working, to search the web it is working, 9Gag is working on data.
Data it is enough- almost one GB
I have the Samsung Galaxy simple - Google

Please help me and let me know if there is something I can do.


Thank you.

Assuming that you're not behind the Great Firewall of China (which blocks apps like that) and it sounds as if you're not because they work on wifi, it sounds like a DNS issue, and that's best taken up with tech support at your carrier. (They supply the DNS server you use on mobile data - if it has bad entries, you can't get to those addresses.)
