It is not necessary to have a PC or laptop computer to download MicroSIP. The software is also available for the iPhone, iPad and Android devices. In order to download the software, you simply need to go online and find a website that allows you to download a program for your device. Once you are in the site that allows you to download, you will notice that it will require you to enter your Microsoft account information. After you enter the username and password, the website will be able to run a check on your accounts to see if there are any existing subscriptions to be cancelled.
After you submit your information, you will then receive a confirmation email that will tell you that you can download the software for free or for a limited time, or a free trial. It is possible to download MicroSIP for free but the software is only available for a limited time, for example, for a week or two. If you do not want to use the software for one reason or another, you can always cancel your subscription and download the software again. However, you will be required to pay a small fee if you wish to download the software for an extended period of time.
You can use the download area at the site that you purchased the software from to make sure that you only get the software for the period of time that you actually have the free trial. Then you will not be asked to pay the fee and be able to use the application without any limits. The same goes for paying for the application through the internet. It is always best to cancel the subscription when you are done using the application because it can sometimes result in penalties that may include the inability to use the application, like being unable to call the number on your card.
