Is it already cheaper to make calls with mobile VoIP?
By choosing correct wireless data plans, the mobile VoIP can be even cheaper. For example, subscribers of Tempo Music from Mobistar (Belgium) only have to pay 0.25 euro for each session (less than 1 hour or 1 MB traffic). If Fring or Talkonaut only uses less than 100KB traffic, it means users can talk to more than 10 minutes for 0.25 euro. And for users with “unlimited” data plan, the average price can be even cheaper.
