Viber VoIP hits Android: Free international calls and SMS [Video]

July 20, 2011
114

Free VoIP service Viber has launched its first Android app, allowing Android handset users to take advantage of free international calls and text messages. Already available for iPhone users, Viber differs from most VoIP services in that it doesn't demand registration; instead, it uses your own phone number.

When installed, Viber searches through your phonebook and identifies which of your friends are also using the app. Calls and messages between you and those people are then routed via your phone's data connection - either WiFi or 3G - rather than via your carrier. It's probably best to have an unlimited data plan, however, since VoIP calls over 3G can get use up a lot of data.

Obviously, the more people you know using Viber, the more calls and messages you can offload to the service; that seems to be the company's main growth plan. The app is a free download and there are no adverts.

        cannot load viber, when I click on icon it just show black screen and than return to home screen… I uninstall it and cannot instal it again from market again

      • http://www.viber.com Viber

        Are you sure you are running a Nexus S and not Galaxy Nexus? The problem you are describing to us happens on Galaxy Nexus and is a known issue that will be fixed soon.

      • http://www.facebook.com/profile.php?id=574287120 Jurica Jura Jurković

        I’m pretty sure that I know which device I bought and use. I managed to install viber but still cannot use it, black screen and return to home. 

        Please fix it soon, I miss viber!

        Are you using a Custom ROM?

        If not, which version of android are you using?

      • http://www.facebook.com/profile.php?id=574287120 Jurica Jura Jurković

        No, stock ICS, version 4.0.3

      • Rquinter_cr

        Same here.  I have a Nexus S running ICS and Viber does not work at all.  It freezes after install and run for the first time.

      • http://www.viber.com Viber

        This is a known issue that will be resolved in our upcoming version 2.1.3 (coming to Market within the next several weeks hopefully). Stay tuned for updates.

    • Giorgio Suraci

      Voice call over data connection (either 3G or HSPA) is a joke.
      You won’t be able to actually communicate unless you’re on wi-fi.

      I’ll try some other apps…

      • http://www.viber.com Viber

        Viber does not offer Video calling yet, but we will in the future. The network on which the user decides to make the video call is solely her/his personal decision :)

  • Peter Clark

    Frankly speaking this is a useless application for mobile voip. First of all already many providers like axvoice are offering their own applications for android and iphones. Secondly, It is just a re-invention of the wheel.

      DID YOU EVEN READ THE COMMENTS BELOW ?????!!!!!!!!! SPECIALY FROM THE VIBER TEAM…

    • http://www.viber.com Viber

      Hi,

      We are aware of this issue, and working hard to fix it these days.

      Our upcoming Viber 2.1.3 (coming soon to Market) will be compatible with Ice Cream Sandwich. We apologize for the temporary inconvenience.

  • Qazwsx

    Is there an estimating date for the new version?

    • http://www.viber.com Viber

      For which device?

  • Dimitris Argirakis

    is there a chance for a workable version for the Ice cream soon?

    • http://www.viber.com Viber

      We’re doing our best so it is ready as soon as possible.
      As you know, many fundamental changes were made on ICS (not only visual improvements). In order to adapt Viber to ICS the best way and make sure we don’t release a half-baked app, we need some time for developing and testing.

      We wouldn’t want to guarantee a specific release date at this stage. Once we have any news we’ll keep you posted – we apologize for the temporary inconvenience.

  • Aakash

    what is the reason to pay big money if the software like Viber does not work ???

    • http://www.viber.com Viber

      Pay who? Viber is a free app ;)

      And why does Viber not work? What is the problem you’re experiencing?

  • Hhhhh

    @ViberSupport its very weird why the normal phone call rings while calling on viber ??? its very embarrassing like u are fake calling!!!!

    • http://www.viber.com Viber

      Hi,

      If you’re referring to the fact that normal (cellular) calls interrupt Viber calls, that is due to some limitations on the phone/Android itself – cellular calls must have priority over any application.

      We are working these days to see if this issue can be bypassed, and if we have any news, we will announce it on our Facebook page.

  • Paranull

    @viber team : what are you guys doing? are you coding a new os for smartphones to run ur old app or u r just updating the old viber to support ICS?? take a look at those comments…some of them are 2 month old and you havent released an ICS version yet!i think viber will support ICS as soon as Android OS 5.0 release!

    • http://www.viber.com Viber

      Actually,

      Major progress has been made, and we expect the release to be ready within the next 2 weeks.  It’s important to understand that it’s delayed because we want to ensure that the app is released free of bugs.

  • Wael-hammam

    viber team , what on earth are u guys doing?? i have been hearing that the update will be available in a few weeks , and that it is just around the corner , and in the next couple of weeks,

    • http://www.viber.com Viber

      As we replied above, the app is going to be released within the next several days.

        regards

  • GeorgiaDawgs97

    My fiance lives in Peru, and I live in the USA.  When I try to call her on Viber, the voice is very delayed when she speaks to me and when I speak to her.  Will this be fixed? I was hoping it would be identical to a regular cell to cell phone call. 

    • http://www.viber.com Viber

      lag in Viber calls is usually caused due to a non-stable or slow internet connection on either side. Please test it when both you and her are connected to a few different WiFi networks. This way you’ll be able to find the problematic network on either side.

    I’d like to use this to call US from Peru on a trip next month. Does each person I need to call have to have the Viber app installed on their phone for it to work?

    • http://www.viber.com Viber

      Yep,

      Viber provides its service between 2 users who have Viber installed and are connected to the internet.

  • angel lay

    I like to US from UK, but I don’t know which code number that I have to use…thanks

    • jack

       001 is the code for US

    • http://www.viber.com Viber

      Hi,
      Please see our response above on this matter.

  • SusanChelly

    Hi, I am planning to Call UK (cell phone) from US. I have no idea what international code that I need to use

    • Jack

       +44 is the international code for UK

      • SusanChelly

        Jack, Thank you…

        Do I have include 011 too? My friend’s download the viber then his number showed in my viber list as +44(his cell number). But I have no idea that I have to add  
        011 then +444(his number) when I call. 

      • http://www.viber.com Viber

        Hi Susan,

        In order to dial/save that friend’s number in the UK, you (in the US) need to dial/save it in this format: 
        +44 xx-xx-xxxxxx  , excluding the “0″ at the beginning of their original cell number.

        Note that the “+” easily replaces the “011″ code you mentioned, so there’s no need for it whatsoever.

        If they want to add/dial your number, they would use +1-xxx-xxx-xxxx

      • SusanChelly

        Thanks for helping me out

      • http://www.viber.com Viber

        It’s our pleasure to help our users, as always :)

    Is Viber compatible to Samsung Galaxy Y S5360 (Android 2.3 – Gingerbread)?

    • http://www.viber.com Viber

      We haven’t thoroughly tested Viber on this specific device yet. You can check out our list of officially supported devices at: http://bit.ly/rqbZEw

      However, in the meantime you can still download Viber from Market, try it out and we would be happy to receive your feedback on how it works on your device so we could improve Viber accordingly.

      So far, we have received reports from some users that Viber works fine on Galaxy Y

      • Angel

        Hey,

        Thank you very much for the guidance and quick response!
        I wanted to learn about the above before buying the handset and your guidelines motivated me to continue with my decision.
        I bought the handset and installed Viber application and I am happy to share that:-’Viber is very much compatible with Samsung Galaxy Y S5360 (Android 2.3 – Gingerbread)’. :)

        I am happy with the handset as of now and definitely Viber as well!

        Touch wood :DPari :)

      • http://www.viber.com Viber

        That is great news, we’re delighted to hear that it works smoothly on your new Galaxy Y.

        Enjoy, and feel free to let us know if you have any other question/suggestion :)

  • Kalpesh_iway_007

    hi,  please tell that viber can use in samsung y ?  and its easy to use ? or have any charge for using viber… 

    • http://www.viber.com Viber

      We haven’t thoroughly tested Viber on Galaxy Y yet. You can check out our list of officially supported devices at: http://bit.ly/rqbZEw

      However, as far as we’ve heard from our users, Viber seems to work just fine on Galaxy Y. You can simply download it from Market and try it out :)

      About charges – you don’t need to worry. Viber is a completely free service.

      • Kalpesh_iway_007

        thanks for reply  ,..but without wifi …in normally interenet service we can use viber  in samsung   y for free ? 

      • http://www.viber.com Viber

        Viber itself – the app and the service – is totally free, meaning we (Viber) don’t charge anything from you.

        Since Viber uses the internet to function, both sides of the conversation must be connected to either WiFi or 3G. If a user is connected to WiFi – that user is not paying anything for sure. If the user is connected to 3G, the user *may* be paying his cellular company for the data (Viber uses 0.25MB per minute of call), but that depends on the specific data plan that he has with his cellular company, and needs to be verified with them.

    • http://www.viber.com/ Viber

      Hi,

      You were asked for your credit card probably by AppStore, and not by Viber, since we don’t need your credit card for any purpose (Viber is completely free).

      Have you tried contacting AppStore support?

    • http://www.viber.com/ Viber

      Hi,

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

      1. First, please try uninstalling and reinstalling Viber when connecting to a few different WiFi networks (in order to pinpoint the source of the problem). What are the results?
      2. Also, please make sure the following ports are enabled (“forwarded”) on your routers or firewalls:
      TCP: 5242 + 4244
      UDP: 5243 + 9785

      (if you are not sure how to enable ports, you may contact your router manufacturer or your Internet Service Provider)
