Call15 have a new way of getting cheap international calls from your mobile. Check it out:

1. You have to be with O2
2. You dial a Call15 number to get a preset number of minutes (there are different numbers for different call lengths).
3. You then dial the number you wish to speak with.
4. You get a warning when you have less than a minute left, in time to say your goodbyes and end your call.
5. You get billed a set amount to your account.

That’s it. No set up, no registering, no codes to remember, no standing on one leg and rubbing your tummy while holding your phone in the air.

Until I tried it out, and double checked everything, I had trouble believing it could be so simple, easy and cheap - so in case you are like me and ridiculously sceptical here it is again:

• Call the special number
• Dial in the international number
• Talk
• Pay a set rate for a set amount of minutes.

So if I tell you the numbers now, and you have an O2 phone, you can get cheaper international calls right now. The numbers are always the same, but the rates differ somewhat depending on the country you are calling - check out their site for full details.

Here are the numbers, and example rates which at the time of posting applied to the UK, France, Spain and Italy (Poland is even cheaper than rates below!):

In the interest of full disclosure, I should tell you that I may in the future do some illustrative work for Call15.com which is how I came across them (yes, i work as well as post on BifSniff - oh, and thanks to Pat Phelan for the introduction!) but I wrote this post simply as someone who has seen his bill spike horribly from calls to family in the UK and can see the HUGE potential in such an easy way to cut costs.

As an added bonus, Call15 are currently running a competition to win an iPhone, and are also giving away O2 sim cards (for a limited time) - so if you’re not currently with O2 you can still start making cheap calls.

If you try this out, let me know what you think… am I overly excited about this? Is it old news? Have I been living under a rock? The new economising Frank is well impressed.
