HeyTelliTunes link: HeyTell - Â£Free
The push-to-talk feature found on some mobile phones is reasonably popular in the US, but it hasnâ€™t taken off in the UK partly due to limited network support. However, if you have a friend that you need to communicate with, but donâ€™t want to rack up huge call charges and canâ€™t be bothered with the hassle of texting, then HeyTell is worth a look.
You can think of it as a Walkie Talkie style instant messaging service. You press the button on the screen, speak into your iPhone and your message is delivered to your friend over either 3G or Wi-Fi. Once they receive your message they can respond in exactly the same way. Best of all, both the app and the service are completely free.
HeyTell is a simple but effective Push-to-Talk style instant messaging service thatâ€™s very easy to use.
