There are reports coming in tonight that Vodafone within Europe has begun blocking all VoIP applications from functioning over the 3G networks, restricting them to use WiFi.
iSpazio notes specifically that the ban seems to be enforced in Italy with VoIP apps such as Skype, Viber and Tango no longer functioning over a 3G network and that when Viber tries to make a call over Vodafone’s 3G network that the following message is displayed;
An Internet connection is required to place free calls Viber. Check your connection and try again. Place a regular call instead.
Other users commenting over at AppAdvice in the UK and Greece seem to still have functioning VoIP capabilities over the Vodafone network in those countries and Vodafone has not confirmed or denied anything at this stage.
Although iSpazio claims that only users on the Mobile Internet Plus plan (at 8 Euros extra) will allow VoIP, whereas Vodafone has blocked VoIP traffic for the users on the lower cost Vodafone Mobile Internet and Smart plans.
Are you a Vodafone customer in Europe (or Australia)? Have you had your VoIP calls over 3G blocked, and if so do Cydia applications such as 3G Unrestrictor work? Let us know in the comments.
