Truphone growing its coverage

From a niche, but vocal, provider of cheap calls over WiFi & 3G, Truphone is developing into a proper virtual mobile operator.

It’s recent purchase of SIM4Travel complements Truphone’s original dependence on WiFi enabled S60 smartphones.

Now it can offer cheap calls irrespective of the handset capability or whether it’s within reach of a WiFi signal.

Last year T-Mobile tried to block VoIP ports in a crude attempt to preserve voice revenues.

Now though Truphone has a platform to negotiate the keenest rates for data roaming, and offer inexpensive flat rate VoIP calls over 3.5G and future 4G networks.

Good move.
