Wi-fi hotspots are sprouting everywhere - cafes, malls, hotels, airports, etc. During the testing phase of Waterfront Cebu WLAN network, I made VoIP calls using my laptop and USB phone. I was able to contact Camiguin, Cagayan de Oro and USA. The quality is good - not bad for a free call. What could be a better device to use than a WLAN-enabled mobile phone? Imagine you can even make free calls in hotspots and still be able to text/talk through your regular network?
I was looking for WLAN phones to recommend to a prospective client. I found GSM phones w/ WLAN feature. Aha, this is it - a dual-mode GSM/WLAN mobile phone! After some searching, I found a good candidate - the Nokia E Series. Those units have SIP feature, the most popular protocol used in VoIP phones. So this phone can do VoIP in Wi-Fi hotspots. Perfect.
But to the newbies, this is their major stumbling block - what is SIP? SIP stands for Session Initiation Protocol, the widely used standard in Internet telephony.
Without going into technical details, first, you have to have a SIP account. Just like your email account, it has login name, password and host name (or address). SIP-to-SIP calls is unlimited free regardless of mobile network carrier.
After researching many SIP providers, I recommend Callcentric and you can register here for a free Callcentric SIP account . Second, you enter your SIP account details into your mobile phone. That’s all. When your mobile phone is connected to a hotspot, it works just like a regular phone. Once you have your account, post a comment here and I’ll send you details how to program your E51 mobile phone. Programming other models would be similar.
Enjoy free calling anywhere in the world!
sorry i’m not familiar w/ E65. pls check the manual if you can find terms like internet call or SIP. if there’s none, you can download Fring from http://www.fring.com. it’s cool. you can YM, too.
