My experience with Truphone

Truphone is a mobile phone specific VOIP service provider (So far only supporting Nokia phones) that currently offers free fixed line calls across 40 countries until end of Feb 08. Being an avid VOIP user I was keen to find out how well Truphone performs on my Nokia E61 and plus it was free, so what’s to lose?

Truphone is not difficult to install (you do have to read the instructions). Its software configures truphone’s VOIP/SIP settings unlike other VOIP services where you input the configurations yourself in the E61 internet call settings. As added bonus, Truphone software does some basic WLAN priority/roaming management.

After a few months of usage, the network connection and voice quality are excellent when WLAN reception is good. Truphone has an AP priority list that you register WLANs you will use and if you move from one registered WLAN to another, Truphone services will automatically be enabled once you are in any of the registered WLAN coverage.

Overall having free calls overseas definitely has put me closer to my family and friends and truphone’s free call promotion have been most excellent. Would I continue to use truphone once the free call promotion is over? I would hunt down the lowest VOIP/SIP call rate provider and use them; hope that answers the question.

Having VOIP/SIP function on my mobile phone is a godsend. No longer am I strapped to my notebook for Skype etc calls but am free to enjoy low call rates whilst I walk around home/office. I’m sure millions around the world receiving their first convergence device with GSM +VOIP enabled would agree. There’s no turning back now. Go mobile VOIP!
