USSD. You enter the 'to' and 'from' phone numbers and press 'Go'. The 'from' phone rings, you answer, it asks you to wait, then rings to the 'to' phone. When I asked Telna about this feature, they were surprised my SIM had it. They told me it was a feature provided for one of their wholesale customers and not intended for retail users like me. I was actually asked not to mention that I had it. I think it might upset their roaming partners if it became common knowledge. While not a critical feature, it can save a few cents per minute if both 'to' and 'from' numbers are landline rate calls. For example, the cost to call the US from Bahamas would be closer to 20¢/min this way, vs near 90¢/min by their cellular roaming. Please don't call them up and ask about this. They might turn it off.
Two other features I like with Telna are the WiFi calling feature based on a standard SIP client and the ability to call a Telna phone via a SIP address.
