Fring
Try Fring. It connects to all the major VOIP, voice enabled IM, and SIP clients,
including Skype, Yahoo, MSN, ICQ, Gtalk, other Fring clients, and so on, over 3g,
4g, or wifi. All your carrier will see is you using data, and your friend can use any
client they like. It's nice having to only keep ONE app to talk to someone no matter
what client _they_ use or like.
You can buy minutes for it like Skype does, so landline calling is also doable.
FringOUT minutes are usually cheaper than Skype too, bonus.
If you have unlimited data but are short on minutes, give it a try. I've had fantastic
luck & success with it, especially for talking to my other friends using several other
types of phones on several other carriers, as well as talking to their laptops and
home computers too.
(I use Verizon which is automatically unlimited to other Verizon users, is what I mean)
Oh, it does video too. Wish I had stock in this company, but, alas, no such luck.
Another option I haven't tried yet, but which is on the front page right now, is the
new Yahoo Droid app that was mentioned to be multiple client aware like Fring.
If I get a little time I'll see about setting that up and determine if it has good sound
and how well it connects to other non-Yahoo apps and see how much their minutes
cost for landline usage, etc.
I'm really slammed the next few days though and I'm almost done with my morning coffee
today, meaning no more goofing off now, so I don't know how long it'll be before I can
report back my experiences to you, friend.
I will try though, to find a wee bit of time. Options are good, and if this app is better
than Fring, I certainly would want everyone to have the very best for their Droids.
