With a laptop, dual mode handset, or WiFi (News - Alert)-enabled IP phone, users can easily make VoIP calls from home (assuming a wireless network) or the office (assuming the same). Strategically placed hotspots expand the potential of mobile VoIP — if you are a subscriber — and the growth of metro WiFi networks certainly makes mobile VoIP a possibility. The one commonality between these means of access, though, is that the user must be within range of a wireless AP (access point) in order to remain connected. Yes, there are several ways to make VoIP calls while in transit.

 

There are hitches, though. Not everyone has a dual mode phone; not everyone subscribes to wireless hotspot providers; most cities do not have metro WiFi networks in place. All of which makes it considerably more difficult to place or receive VoIP calls while away from your desk.

 

On the other hand, most people do own cell phones, and some mobile service providers have begun to understand there must be a way to benefit from VoIP without a direct IP connection. Mobivox, for instance, has created a service that enables Skype calling from a mobile phone for as little as .03 per minute. Rebtel (News - Alert), now, has its own wireless VoIP service — for as little as .02 per minute to many locations — that can be used by all mobile callers.

 

The global VoIP provider has set up a wireless VoIP Web site where users can register for and use the Rebtel service, bypassing the need for PC access to initiate an account. Without any software to download, and without a sign-up fee, Rebtel users can place VoIP calls to any phone in the world via a local number. The user dials a local number, which then traverses cities, states, countries, and continents via IP connections, then terminates at the selected number. The caller can then ask the other party to call the Rebtel number that shows up on the Caller ID — then the entire call is free, since both parties are making local calls. The only charge is mobile minutes usage. Users can add and manage Rebtel contacts directly from their mobile address book, making this service easy — and inexpensive.

 

“Our customers look for ways to add more convenience to their mobile lifestyle,” said Souheil Badran, president and general manager, Americas & APAC for Rebtel.  “We have now simplified the process even more to make it practical for them to join and add others to their favorite international contact list.”

 

Now, by creating Rebtel numbers for any internationally based (in 37 countries for now) family members, colleagues, or friends, users can place cheap, high quality calls to them as easily as to anyone else in their phone book.

 

With services like Rebtel’s mobile users are finally beginning to gain the benefits of VoIP without being tied to a desk or a mobile provider. 

 

“We are providing a truly mobile service, so anyone with a data connection from any type of mobile device — PDA, smartphone, regular mobile phone — on any network can stay in touch with family and friends while on the go,” said Hjalmar Winbladh, CEO of Rebtel.
