Next week I will be at the Mobile World Congress in Barcelona and I will take my Maxroam SIM card with me. So outgoing calls to German landlines will cost only €0.38 per minute and incoming calls €0.25, instead of €0.58 and €0.28 which a usual German cell phone provider would charge me. Before last year's regulation these prices where even higher. In some countries I'd still have to pay €2.49 per minute for a local call while roaming. To be reachable in Barcelona I will forward my Berlin office number for free to the UK fixed line number that I have on my Maxroam SIM. I will either use my own ATA for that purpose or a new Maxroam feature.

An outgoing call with Maxroam is a litte bit different from a normal mobile phone call. It doesn't start directly. Instead you see several status messages running over your phone's display, like "calling", "requesting" and then again "calling", before you receive an incoming call with no number. That's Maxroams server calling you. A voice says "connecting, please wait" and contacts the callee. This entire callback system is based on USSD messages. That's a kind of free short messages in GSM networks, which can be sent only between the user's handset and the provider. USSD had been invented to let you check the amount of prepaid minutes on your SIM card for free. Nowadays it's often used as a 'trigger' to invoke independent calling services like Maxroam. Think of it like Jajah, but without the need to pay for mobile data usage for the communication with the server.

The Cubic phone, which can also be had from the company for usage with the Maxroam SIM and for VoIP over Wifi, is so packed with software that there is no space left to secure it with a PIN number. Maxroam's CEO Pat Phelan told me in an interview: "It’s very packed on the operating system and we have had to leave room for the two logging on GUI for the hotspots". In the last quarter the company had lots of backend work going on which now result in further improvements, as Pat Phelan told me in an email:


1. Live billing
We now have full live billing for all users on our backend, make a call, hang up and we instantly display it.

2. Add a local number
As of today we can add local FIXED line numbers to your MAXroam sim from 52 countries. (MAXroam only use fixed line numbers unlike other companies which use international mobile or premium UK mobile numbers where the average users have no knowledge of what it costs to dial the SIM and your friends are just subsidizing your roaming). This list is being added to every day. These numbers begin at €1.05 per month and you can pick up, drop as many as you like, minimum commitment is only a month.

3. Free Call forwarding
When you arrive in your destination sometimes you have access to a hotel room or an office number, we will now allow to forward all your MAXroam numbers totally free to fixed line numbers in a list of 48 countries so you are roaming for ZERO COST.

4. SMS only 5c
Once you log into your MAXroam account we will allow all users to send SMS anywhere in the world from the backend for only 5c per message.


But the most interesting announcement he already made in November, when I asked him in an interview for the German magazine ProFirma about Maxroam's prices compared to other companies like Sunsim, Globalsim or TouristMobile:

Our pricing is only at the beginning, most of these company are just resellers and I don’t mean this as an insult, we are building a global brand here, our aim within 1 year is 20c in and out in Europe and under 10c in the USA. Our next sims will be 128k Java with between 6 and 16 IMSI on each sim depending on your travel arrangements, so you arrive in India, we have an Indian IMSI on your SIM and you roam at discounted rates, we are not depending on other peoples roaming agreement and are at present travelling the planet signing independent roaming agreements.

Under €0.10 in and out? Now that would be a great price for USA, where Maxroam still charges €1.10 or more for incoming and outgoing calls. I can't wait to see these 6 and 16 IMSI SIM cards. That's like taking 16 cell phones with you, each one with a local card. So you don't have to pay for incoming calls.

Last year I was nagging that "Packet8 MobileTalk could be done much better", and I was right. I could learn that now when the Israeli company Mobilemax installed for me on a cellphone the underlying software which powers Packet8's MobileTalk. It is a real mobile VoIP wonder weapon which I covered in an article for Areamobile. Companies like Truphone, Gizmo5, Wifimobile and Tpad should make its features a part of their mobile services to make them work also outside of the spare Wifi areas.

Internet telephony could be a killer application for mobile phones. But it has it quirks, shows a series of articles I wrote. In most cases you need at least a cell phone which can open mobile websites. It let's you do a mobile callback with VoIP providers like Jajah or Voxalot. After entering the phone numbers of the caller and the callee on a mobile website, a server rings up both and connects them over the internet. Of course this also costs double, but for international calls it's still cheaper than the own cell phone provider's prices. Only Wifi cell phone calls are less expensive. They only cost a few cents per minutes and often they are free. But Wifi isn't always available.

Mobilemax thus developed a software which automatically sends mobile phone calls the less expensive way over the internet whenever that's cheaper than normal calls. No need to open mobile websites on the phone or to trigger callbacks by SMS or instant messaging. The software simply sits unobtrusively in the background and automatically determines the way in which the call is connected. The user only needs to enter the number.

Establishing a call with VoIP software from Mobilemax

The program works on about 500 phones with Palm, BlackBerry, Symbian or Windows Mobile operating systems and last month it has been deployed for the first time by the US VoIP provider Packet8. Once a number has a foreign area code, the software starts to act and connects via a landline number to the server by Packet8. The server connects the telephone conversation with the other party over the VoIP network. Calls from the United States to Asia or Europe cost only a 2 to 5 US cents per minute more than the price of a local call. The American mobile operators normally charge up to three dollar minute. German companies like Running Mobile or Cellity offer similar solutions.

But the Israeli software has much more functions which the competitors lack and also Packet8 doesn't use. The program could also automatically decide to connect a phone call as a callback or over Wifi. Even VoIP calls over 3G will soon be possible, although all German mobile network operators seem to block them now I realized in some self-experiments. Mobilemax' software is a real miracle weapon for mobile VoIP and the handling is particularly pleasant, because no extra buttons have to be pressed. The software even senses in which country the user is and automatically chooses a local number for callthrough or callback. What a pity that consumers cannot have it. Mobilemax distributes the software only to companies. "We don't see ourselves providing the underlying service of the application and compete with our customers", said Mobilemax' Director of Business Development, Perry Nalevka, to me in an interview. The Packet8 customers pay $10 per month only to use it. In addition they get the VoIP telephone minutes billed.

Configuration also allows other VoIP flavours

Other companies want to follow the same business model, Nalevka said, which started as a one-touch-dialing solution for calling card users and roamers who had to use tens of access numbers, PINs and dial flows to make a call without being ripped off by the mobile operators. Six different service providers worldwide and several IPBX and enterprise mobility providers are now testing the software. So far several tens of thousands of licenses purchased.


Other companies who use it:

• Reliance - Indian provider launching in 8 countries soon.
• Gamma Telecom, UK - launched the Crosslink service targeting SMBs and enterprise users
• Tellink, Belgium - callback provider for SMBs and roamers
• Tel3, Miami FL - residential provider
• Boomering - SMB mobility & callback solutions for roamers
  

Today it supports the following configurations:

• Callthrough with PIN or PINless (CLI based).
• Roaming location based callthrough with multiple access numbers automatically selects the relevant access number according to the user's location.
• Seamless callback triggered by: DID, USSD, SMS, IP. The application triggers the callback, answers the incoming call and if needed sends the destination number.
• Dial around replacing prefixes in the dialed number (1010).
  

Further developments:

• Support additional phone models as they are released.
• Add new routes to seamlessly divert calls to: VoWIFI, Vo3G (to SIP or termination).
• Adding in-call Mobility features.

You can find more information about the software in Rich Tehrani's interview with Perry Nalevka: "MobileMax: Bullish on Fixed Mobile Convergence" (December 31, 2007).

The VoIP company Sipgate, one of the biggest in Germany with also significant business in the UK, offers a special service for developers. "Sipgate API" is a new interface to integrate almost every Sipgate function - VoIP, SMS and large administration tools - in own applications. The Sipgate API enables to use central Sipgate functions within your own software or web projects, so that VoIP tinkerers can set up their own mashup services.

In his latest blog post Thomas Howe, the master of mashup, was so kind to explain again what mashup means:

A mashup is an application that uses
1) modern Web integration technologies
2) to take content or services from two independent sources
3) to solve a unique or niche problem.

The first element of mashups are the integration technologies they use. These integration technologies create a “web as platform” architecture, allowing the mashup developer to integrate his software on top of the world class infrastructures provided by Amazon or AOL, simply, easily and safely. The most common technologies used for mashups include Web services calls, which either come as a SOAP or REST flavors, AJAX, Javascript and Ruby.

The second element of mashups is that they take content or services from more than one independent source. This is where the “mashup” word comes from. Mashups take things that might not go together, and puts them together in a valuable way. The classic mashup is the Chicago Crime Map, that took data from the Chicago Police Department and plotted it on Google Maps, so that you could see where the burglaries happened.

The "Sipgate API" is provided free of charge and can be used for mashups with every Sipgate account. Up to date the fax function of Sipgate can be used only with the German service.

To make integration easy, Sipgate publishes also the source code of the Firefox extension "Sipgate FFX" as well as several Perl examples and a KDE panel application under a GPL 2 license. Further more .NET developers will find with "sipgate API .NET SDK" a comfortable library to use the "Sipgate API" services easily. Over a mailing list developers can also exchange experiences and tips.

You will find all information about the interface and the exemplar applications including detailed documentations under www.sipgate.co.uk/api.

The Betamax company Voipbuster now offers free SMS from a mobile phone. I have just checked it out and it works great. You just have to install a small Java applet on your cell phone. Voipbuster routes the message as so called "UrlSms" over their servers. The SMS is free, besides of a little 3G data traffic. I have just sent two totally free SMS over Wifi from my Nokia E61. The messages arrive within minutes and seem to be a tiny bit slowlier than normal SMS.

1) How to install:

• On your mobile go to http://gsm.voipbuster.com/ (on some mobiles you need to choose 'download application' on some phones you can just go to the webpage).


• download and install the application, start the application (for most mobiles: in the menu, go to applications)


• in "settings" fill in your VoipBuster username / password and your mobile phone number

2) How to send SMS:

• start the application (for most mobiles: in the menu, go to applications)
  
• go to options --> sms
  
• you can select the person you want to send a sms from your mobile phone contacts through options --> add from contacts
  
• type your message and hit SEND!
  
• your mobile phone will ask you to open a data connection. This uses just a tiny bit of data traffic.
  
• Voipbuster charges you nothing! Yes --> NOTHING!

Again I wonder how Betamax will refinance this service. But they already surprised me a few times with such offers. Normally they don't last too long and then become paid services at cheap prices. I guess it's just an introductory offer.
