The good part, that it’s not VoIP based (outbound from your device) since its a callback to your originating phone to reach destination.

I tried Jajah and discovered their business model was hazy and the claims on their web site misleading. For a Web 2.0 company – that’s a shame.
The issue is that Jajah claims that calls between registered users using land lines are free. Also they have a fair use policy which is OK and fair – you are limited to 60 minutes a day which is also fine. But…if you adhere to Jajah’s policy and respect their fair use policy – your calls should be free. They are not!

What happens is that you register two numbers in the designated “Free” zones and the first few calls are free…the web site even tells you: “this call is free” … then…suddenly and without any warning or explanation… you get a message that you must pay Jajah or the free service is discontinued.

I corresponded with the company at length and got back a tirade of “double-talk” claiming that to continue with the free service I needed to “maintain a positive credit balance” on Jajah’s account.

So I checked out the company again making sure I read everything(!) on their web site: I registered another land line, had a friend register his land line – both in the “free call” zone…and started the service. At first the web page shows the calls are free. Then, suddenly, a message appears that the call costs so and so cents…Even though its the same numbers and the Fair Use Policy is strictly respected – Viola the catch…My “65 cent credit line” disappeared and up came the request for payment…

Folks…this is not Skype… Skype is simple…Skype is free…Skype tells you clearly what, how much and when you need to pay. Jajah’s business model is simply a tricky ploy to get customers to pay for another VOIP service that in itself is not unique and not very competitive…If you want regular, non-PC, phone based service get 8×8 or sunrocket!

Callback is inherently flawed as it takes minimum two calls instead of one, it makes for a nice periodical replacement while companies like http://www.briing.com manages to get the wholesale prices right and makes the vMVNO possible using application that uses access number interconnect agreement.

Briing.com is an alternative to the VoIP services, which concerns access number, interconnect rates, and makes it a lot easier for the end user also to understand pricing and use. Briing Mobile saver so far only works in the UK so far, and can only offer direct free calls in the UK. http://www.briing.com/saver a smart java application, not yet on the symbian OS phones but on all the real handsets out there. The nokia 6230, series 40 phones, this is where the majority of phone users are, the N series E series Nokia is so far has very little penetration.

There are still a whole lot of people with older phones, and who are not necessarily changing phones quickly. It is only in the UK phone are completely subsidised by a contract and are “free”.

It will be an intersting battle, the operators, vs voip services and access call back, the sure winners are going to be the wwholesale price brokers and the consumers. The rest is up to wit and consumer adaptation and critical mass saturation

I have it on my Nokia 6680 installed. I used the service recently to call my sister in Spain.

JaJah service is OK when you are on the road and you call from GSM rather than WiFi for an international call only. Within a country it is much more expensive than the mobile tarrif. Even calling international you get charged an outgoing SMS or GPRS data bundle connection fee once, which you need to add to your bill

However if you are at home or a WiFi hotspot the service is very expensive compared to the (( truphone )) service. While the call to Spain cost 8 pence with (( truphone )), JaJah charges 32 pence. + your SMS, GPRS connect. So it is around 4 times (400%) more expensive; it holds also true that the least cost routing solution they build is quite simple to emulate and the applicable could be bundled to the more forward looking (( truphone )) service. Another downfall I discovered is the hassle of waiting before it connects the call. For a fast moving business executive a hassle which I felt would be unacceptable. And lets not forget (( truphone )) offers free calls to almost all landline (1.6 bn) in the world. Everybody should have the possibility to get a Nokia E60 with this kind of saving on the Mobile Bill to experience the cristal clear call quality of http://www.truphone . What an amazing forward looking service they offer. The world will be building an alternative Cellular Network quickly if they make a big break of the existing paradigm. A homage of a very satisfied (( truphone )) user.
