Is this too good to be true.

Calling UK mobiles at only 3.5p/minute

Click on Phone rates

I just tried opening a new account on SMSLISTTO but my registration was denied.

I assume this has something to do with all the new user profiles I've been opening up on the different clients (Voipcheap, Voipraider, Voipwise). I think I have accounts on each of them. It didn't let me log in to all with just one account.

Now I think it is blocking my Ip from registring. Perhaps i have to change internet connections before I can open an accuont on SMSLISTTO, which is by far the chepest one to call UK mobiles. 3p/min.

It is a good rate... but alas is part of mighty Betamax. Don't expect the rate to last! They have a habit of doing just this. Listing ultra-cheap rates to certain destinations then suddenly doubling them once people have deposited some money!

Hmmm, so how to beat them?

What is the frequency in which they double, or change their rates? Is there a site that displays the last update on each Voipservice? Or the next planned update? I think I can beat them if I time it right.

Even if they increase...They will always be cheap... perhaps not the cheapest amongst their various brands! Just don't deposit too much, and in any case you will always be able to get your moneys worth with their fee destinations.

And remember you can always use the credit as a type of an international phone card. There are lots of access numbers for various countries (just not toll free, but they are all local)
