Truphone just gets better and better. The new Truphone client (v3.0) is now available as a sneak preview. It’s a step change in functionality from the previous version, now including SMS send, presence and Truphone over 3G. The SMS functionality now lets you choose whether to use Truphone or GSM to send SMS (with SMS to online Truphone users free). This means your SMS recipients will see your Truphone number, not your GSM number, as the sender. Another step in making your Truphone number a complete replacement for your existing mobile number. Presence allows you to see if other Truphone users are online. Once another Truphone user has agreed to share his status with you, you can see whether or not he is online. Truphone over 3G allows you to use Truphone even when out of range of WiFi. Just make sure you have a fixed price data tariff from your mobile provider.
Also worth mentioning is the excellent quality of Truphone’s technical support, both via email & the Mobile VoIP forum.
