Whistle Phone is an app for calling or texting your family and friends for free over Wifi or your mobile data plan.

On your own customized phone number, you can make and receive unlimited texts from high-definition and secure calls to other Whistle users. You can also make inexpensive calls to landlines and cell phones or text anyone in the US for a fraction of your regular rate when you go Premium.

And, if you need to make calls anywhere in the world, we've got extremely low rates.

Thought about using your iPad or Pod Touch as a phone? We can help you out. And we work pretty darn well on the iPhone too.

(For the iPod Touch before 4th gen, you'll need headphones and a microphone to use Whistle.)

App has to be Open in Order to Work!

This app would be wonderful if you didn't have to have it open in order for it to work since the iPad does not have OS4, you can't have this program running in the background. What's the point when you can't receive incoming calls unless the program is open. It's great if you want to make an outgoing call but once you close the program and try dialing your iPad number from a landline or cellphone, you will get the following msg: "Please hold while I connect you to your party.....I'm sorry but I cannot complete your call." As soon as I open the application and have it sitting on my screen....of course the call then goes through!

Am I the only one experiencing this? What if someone calls while you're checking email? At least push notifications would let you know that you've missed a call. Some type of voicemail would be nice but that's asking a lot. I really don't see the point of this app unless you plan on getting rid of your cell phone completely or don't have a landline nearby. Overall it's decent for being free.

♦️one star for useless whistle phone 👎🏻

Google Voice will NOT re-verify my WHISTLE phone, making it unusable on my iPad Air. It was okay on iPad in 2013. Not now. Whenever I try to verify with Google voice, my whistle phone will not ring. If I dial my whistle number from my local landline phone, it rings OK on my iPad. I've tried 10 times in the past year to verify my Whistle number with my Google Voice. No joy. This app is now useless to me. The only reason I had ever used Whistle is to provide inexpensive VOIP for my iPad with Google Voice. $1 per year would be ok. $10 per month is ridiculous! I am deleting this app. Vail fail! 👎🏻👎🏻👎🏻👎🏻👎🏻
