On February 10, I wrote about a free VOIP telephone service being offered by Dell to Canadian consumers. While travelling (Europe and Asia), I tested it to call home and had mixed results. 1 out of 5 times the call quality was very good, 2 out of 5 times the call qulity was OK and the other 2 times it was unusable. After everyone of the Dell Voice tests, I tested call quality with Skype and it consistently offered a cleaner more enjoyable call.
I also wished that they offered free SMS messages. This isn't something I needed when at home (since my monthly package includes more than enough) but I would have appreciated this when travelling.
I then tested their customer service to inquire about my call quality issues and received a vague non-helpful response about 48 hours later.
Overall you still can't beat the price of free and performance was usually good when in Canada. It is likely an app I'll keep on my cell but will likely fallback on Skype (even if it is not free) for calls when overseas.
