It’s not a good day for mobile operators. First we had free calls via Bluetooth for mobiles from ROK, now we have free mobile calls via Wi-Fi, courtesy of aql.
Sadly, this is limited to Nokia’s E-series phones right now (E60, E61, E70) – but if you have one of those, you can sample free peer-to-peer wi-fi calling over aql’s mobile VoIP network. To connect to aql, you need to text ‘nokia’ to 64446 – your phone will then be configured remotely (no downloads). The outbound caller ID across Wi-Fi is also the same as your existing mobile number.
If the other person doesn’t have the service (or you want to call landlines), calls are cheaper – see the website for details. Whether this is permanently free seems open to question – the company does talk about a "free offer" rather than a free sevice, so it might not last forever. But while it does, could be worth a try.
