If you're attempting to send group texts 100 at a time, you are better off with a web service that handles that. I'm sure there are plenty of sites out there that service spammers for just such an occasion. Sending texts in bulk like this is not legal everywhere, and is usually frowned upon heavily by the people who receive them. If you have that many of hundreds of close friends, I salute you. Most people are lucky to have one or two. If these aren't people you know, then be aware that spamming laws apply, and some people may trace the texts to you and come beat you up. Just sayin'.
