When you want to make cheap calls to other country, no matter what is the reason, you should focus your mind on several, pretty important things that will make the difference for you.
The first thing is the destination and the duration of the calls.
If you want to call Canada or other country, you will need to find a method, which will cut your spendings. This way you can talk as long as you want and still pay less then roaming, for example. This becomes especially important, if the calls you want to make are business calls, which are important for the way your work goes and they may cost you significantly more then their actual price. So, if this is the case, make sure that the method you use is reliable. You will need clean connection, which is not very easy considering the distance.
Skype is one of the alternative variants you can choose from. It is a technology that uses the Internet and therefore is very cheap. However, it has some problems, which may make you say “no”. The first one is the reliability of the technology. It was working perfectly and then Microsoft bought it. Believe me, I use Skype for many years now and the first problem I had with it appeared this year, after the big deal. So, if the call that you make is really important and it costs you big money, I recommend to you not to use Skype. Other weakness of this software is the way it works. You can use it, if you only have a computer or a smartphone. Then, you will have to install the program, which is not the easiest thing in the world. And the third thing is that you can call only people that also have Skype, which means that you do not have countless opportunities.
VoIP is the technology that I use. You can make cheap calls to Canada or other country without worrying for the bill and the reliability of the connection,. It is just perfect.
So, when you want to call abroad, be well informed for the technologies you are about to use and this way you can save some serious money.
