With IPSMS simply type the message, select recipients from your contact list and choose which IP telephone services you want to use to send the message. You can use, for example, SMS77, SMSBug, VoipBuster, 12voip, dialnow, justvoip, nonoh, among others. In order to send the message, you must have an account with and have previously logged into the IP telephone service you want to use.
But once you have these things, the software means you can continue to send supercheap text messages without having to use your PC. The developer recognises there are several current bugs so rest assured they are being worked on. They include: 'First name, Last name' view is sorted by Last name, program crashes on invalid XML phonebook file, history of sent SMS not saved. If you can live with these get messaging, otherwise check the website and wait a while.
Send super-cheap texts but the service is still being developed
