Looking for a free international texting app. 24sms irritates me since every time I get a regular text from anyone this app opens as well. I dont need that. I have the whatsapp app and it works perfectly. But my parents do not have a smartphone and they cannot get the app. I need to text to Cape Town South Africa for Free. It would be nice if they could reply to my message but its ok if they cant. Im am in the US. Thanks.
