    Hi @a_hubbi


    First, please make sure both sides have the latest version of Viber installed.

    Now, please reboot your phone, and test Viber when connecting to a few different WiFi networks. Does the problem occur on all of them?

    my roommate is using viber on the same WIFI and he doesn`t have this problem

    @a_hubbi -



    May we please ask what country you are located in, and which cellular network?

  • a_hubbi Level 1 Level 1

    thanx again 4 replying
    i`m in saudi arabia now and using Mobily network for gsm and ( GO ) as wireless internet provider

  • theViberTeam Level 1 Level 1

    @a_hubbi -



    This may be the source of the problem. We have received some reports from users in Saudi Arabia where we suspected that Viber might be blocked in some networks in the country. This may very well be the reason for the problem you're describing...


    However, I invite you to contact our support team so they can further invesitgate this issue. Here it is: SMRT ticket


    If anything changes (it works, or unfortunately you reach a conclusion that it is indeed blocked) - I would appreciate if you could message me back here

    Hi to Everybody!


    I have read some comments earlier, some cellular providers across the world are blocking the Viber. I'm living in Hungary and using Vodafone 3G. And i can't use the Viber on 3G, just wi-fi. What should i do? I'm always on the road and would be nice to use Viber.


    Thx in advance

  • theViberTeam Level 1 Level 1



    As far as we know, this is unfortunately true - Vodafone Hungary is blocking Viber on their 3G network (just like other Vodafone networks across Europe) - that is for subscribers who did not purchase a special VoIP plan.


    To verify this information, may we ask you to contact Vodafone and confirm it with them? We should highly appreciate if you could report back to us what their response was.

  • kkari Level 1 Level 1

    I did it earlier...

    They said: we don't know this problem, make sure your Viber settings...


    I don't belive this information. I'm an IT and checked everything on iPhone and on viber i can.  And as Viber working on wi-fi and the with the same setting on 3G not...i think the error is Vodafone. Unfortunately.

  • theViberTeam Level 1 Level 1

    As we said, there is a known, widespread issue with Vodafone on 3G all across Europe - we wouldn't want to guarantee anything, of course, but we suspect that this is indeed a block in the 3G network.


    Unfortunately there is not much we can do to help. You might want to try the following:
    1. Try contacting them again, this time saying you knocouw there is a block, and ask which plan could solve this issue for you.

    2. Ask around among friends in Hungary who have Viber and are connected to Vodafone. Do any of them manage to use Viber on 3G?

    3. You might want to find other Hungarian Viber users who might be able to help you. A VPN, for example.

    viber team

    i am hira living in PAKISTAN using iphone 3g the problem wit my viber is that i can't able to use it on wifi its always say cannot connect when i was using it on wifi besides it work not good on my cellular network ... why it is so ??

    please reply me fast


  • theViberTeam Level 1 Level 1

    Hi @ANGALLIE -


    It could be that the network you are connected to is blocking Viber's traffic.

    1. First, please try uninstalling and reinstalling Viber when connected to different a few WiFi networks. Does it work now?

    2. Also, please make sure the following ports are enabled on your routers or firewalls:

    TCP: 5242 + 4244

    UDP: 5243 + 9785

    (if you are not sure how to enable ports, contact your router manufacturer)

    thanks, hope to hear you soon..

  • theViberTeam Level 1 Level 1

    Hi @jantwen -


    First, please see our previous message, regarding the possibility that your network is blocking Viber's ports.


    If that doesn't help, then the cause of this problem might be the fact that your iPhone is jailbroken/hacktivated, and that interferes with Push Notifications in your iPhone. Our support team might be able to assist you further with this issue - please read this page in our official Help Desk:

  • llano10 Level 1 Level 1

    I have downloaded Viber in the US and have gone to europe on vacation, i can only use it with others in europe but not to contact those who are in the US

  • theViberTeam Level 1 Level 1

    Viber should work between any 2 Viber users, no matter where they are in the world.

    Have you made sure that the American numbers are saved in their full international format? (i.e +1-xxx-xxx-xxxx)


    Also, can you please specify which error exactly occurs when you try contacting your American contacts through Viber?
