Bobsled–Make unlimited free calls to USA, Canada, and Puerto Rico and all your Facebook friends

By Alok Saboo on January 29th, 2012

Given how mobile operators are ripping off their consumers, one does not expect a lot from them. It is thus surprising that T-Mobile, one of the largest global wireless carriers, launched a mobile VoIP (mVoIP) service – Bobsled – that allows you to make unlimited FREE calls to USA, Canada and Puerto Rico and also connect with your Facebook friends. Bobsled can be used from anywhere across the world and you do not even have to be a T-Mobile subscriber to use it. So, let us take Bobsled for a ride and see if it worth all the fuss.

Bobsled has two separate services – Calling and Messaging. As the names suggest, Bobsled Calling allows you to make voice calls and is available for all browsers, iOS, and Android; whereas Bobsled Messaging focuses on messaging (including group messaging) and is available for browsers and Android (with an iOS app coming soon). We will focus on the Bobsled Calling service for this post as the Messaging service is very similar to the Facebook Messenger.

Virtually anyone can use Bobsled Calling – it is available for your browser as well as both Android and iOS devices. So, go ahead and get the appropriate version right now…

To start using the service, just log in with your Facebook account and you are good to go. You will see Facebook contacts and you can chat with them, call them, or leave a voice message. You can also use your address book or the dial pad to call any regular landline or mobile phone in USA, Canada, or Puerto Rico.

You can also use Bobsled on your browser, allowing almost everyone (even those without access to smartphones or tablets) to use the service. You may be required to download and install the Bobsled desktop app to use it on your computer.

The following video provides a detailed walkthrough and should clarify any doubts that you may have.

Overall, Bobsled is a fairly powerful service. The voice quality is great and the app is relatively stable. I would have loved to see an option to use the service without a Facebook account, but it is not a deal breaker.

More importantly, it is nice to see a wireless operator extending the benefits of VoIP to consumers. Let us hope that other operators learn from T-Mobile and provide such services to their consumers.

    Sorry for getting offtopic here, I do not know where should I post my query.. 
    Any words on  MAGIC JACK alternative? I am using it for past 2 years and planning 
    to change it.. Something cheaper or free(not beetamax) with DID number.. 
    I prefer device directly plugging in LAN or connecting in wifi without using laptop or PC..
    Please do suggest me mates 2-3 cheapest options so ill try..

    Thanks !!!!

    • Alok Saboo

      You can get DID from IPKall for free, but that may not work for outgoing calls. If you are looking for something cheaper than MagicJack, you may consider Obi110 or Obi100. You just pay a one time charge for the ATA and then can use it with Google Voice to make free calls to USA/Canada.

        It is 50USD however it is unlike magic jack where i can make call and receive from same number…any other suggestion?
        Having one more query, is there any way I can get DID number of INDIA?

        • Alok Saboo

          Get a US DID and then choose the VoIP provider of your choice, but I still don’t think it will work out cheaper than MagicJack.

          Indian DIDs are not allowed by TRAI.

            Thanks for information..

            Could you help me on my other concern…I am using rynga and rynga is betamax and softcall i dont know what …
            Is there any ATA adapter by which i can configure these two providers and plug ata directly in ethernet and make calls without using computer? I know betamax show caller ID but I cannot receive call back on same line because that caller ID number is either my handphone or fixed line.. So is there any way I can use ATA other than OBI110 or 100 to make calls by betamax and receive calls?
            Or like configuring above 2 voip and IPKall so I can make call from voip and receive by IPKAll on same ata?

          • Alok Saboo

            You can forward your IPKall number to the provider that you have configured on the ATA and then you should be able to receive calls as well.

    Thank you for this app! works awesome called family in PR many times.

    • Alok Saboo

      I am glad it worked for you…enjoy your calls!!

      • Guest254

        will the person that i am be charged for the incoming calls? im from the philippines and i use it here.

        • Alok Saboo

          If you are calling from Philippines to US, the other person will use up his/her local minutes (depending on the plan). If incoming calls are free, then there are no charges for receiving calls from Bobsled.

  • Alok Saboo

    An ATA requires you to use a traditional phone with it, i.e., it only provides you a phone jack.

    If you are on the market for ATAs, you may want to look at Linksys SPA3102, Linksys PAP2 or Linksys WRP400. Even the cheapest ATA would be around the same price as an OBi100 or an OBi110, so you need to carefully evaluate your options.

    People can now use the most out of VoIP. It is just quite unfair that unlimited calls are only available at US and Canada. But I just hope soon it will be all over the globe. Thank you for this great app anyways.

    • Alok Saboo

      The benefits of VoIP are evident in many parts of the world. US and Canada have VoIP friendly regulations and the supporting infrastructure and hence benefit the most.

  • sinogirl

    you do not need to use your facebook account to log into the service.

    • Alok Saboo

      Great, looks like they updated the app to be used without FB!!

  • Mujteba Naqvi

    this is a great blog.  Can anyone figure out SIP settings  for this?

    • Alok Saboo

      Thanks!! What SIP settings are you looking for?

      • Mujteba Naqvi

        Instead of using this via the site I want to use it with an sip adapter. So free outgoing calls.  I have incoming handled via callcentic and ipcall.
        I just looking for GV alternatives.

        • Alok Saboo

          Unfortunately, Bobsled does not support SIP and hence you may not be able to use it with your SIP adapter.

          • Mujteba Naqvi

            I’m plowing through your blog.  Do any mVoIP or VoIP services exist that allow totally free calls within the U.S. and to Canada?

            For example MagicJack app calls are free but only within the iPhone, but can SIP be utilized?

            I can’t find the post but I read in that an exploits like this existed with another mVoIP apps.

          • Alok Saboo

            Whistle Phone used to offer SIP support and free calls to USA/Canada, but they are discontinuing the free plan. So, currently I am not aware of any good mVoIP provider that offers free calls to USA/Canada on all mobile devices (other than iPhone).

            I will keep an eye and let you know if I come across anything.
