Mobile voice-over-IP services promise to save money by routing calls over the carrier's data network. As more carriers and phones support high-speed data hookups, such services are growing. We looked at four - EQO, Skuku, Skype for Windows Mobile and Truphone - and found that, although they are much easier to use than those we have tried a few years ago, they are imperfect replacement of conventional voice call service.
It should be emphasized that the quality remains uncertain, at best, and in some cases, it is absolutely abhorrent. In addition, depending on your calling habits, you may not see any savings at all. Most service providers continue to charge a per minute rate, so you'll save on domestic calls, only if you exceed the normal voice plan of distribution (in this case, you may be even better, upgrade your voice plan). However, if you make many international calls, mobile VoIP service can save big money. Of the four services, which we tried, EQO offered the best voice quality, but its rate was significantly higher than in others. Truphone call quality varies, but generally, he proposed an optimal combination of performance and quality at a reasonable price.
Skype for Windows Mobile
This popular VoIP service is available in three versions, mobile: Skype for Windows Mobile, Skype Lite for Java phones and Android edition. (Skype is iPhone application in the work, but at this writing there are no words on when it will be available.)
I tried Skype for Windows Mobile 2.5. The company said millions of people downloaded the software - if it's true, I can only hope they were lucky with him better than I do. After trying in vain (with the help of the company) to get the software and works on HTC Fuze, I easily downloaded and installed it on T-Mobile Shadow.
Like the desktop version, mobile Skype allows free calls to users of colleagues Skype, send instant messages and transfer files. In addition, you can call non-Skype to regular and mobile phones using SkypeOut, a paid service.
Skype says it works best on Wi-Fi connection, but can work on 2G and 3G cellular communications. I have tested it on Wi-Fi, but the voice quality of SkypeOut calls I was miserable, much worse than the calls I made from the desktop Skype. The voting was so divided as to be unintelligible. At the proposal of Skype, I tried using the headset, though the voices were a little louder, as a result, stuttering and breakups are so frequent.
At least, Skype rates are reasonable, ranging from 2.1 cents per minute. It also offers a subscription for only $ 2.95 a month - and for $ 9.95 a month, you can make unlimited calls to regular in 36 countries.
