Went from a iPhone 4s to Galaxy s4 NO GROUP TEXT MESSAGES?

How can I get group text message? I have tried EVERYTHING. The current app I'm using is GroupMe, however all my iPhone friend have to download it if they want to group message me. I have done Go SMS Pro, nothing, still. I have done the app Handcent (not sure if that is correct spelling) Still, nothing. I receive every text individually. I love the galaxy but I loved my group texts!

How to use 750 euros wisely?

I've been saving up for like 6 months and now I'd really like to spend the money but I'm not sure on what. I have a fine phone, I don't need like an iphone because I don't think it's wise. I got a new laptop 8 months ago. I could buy new clothes and makeup but not with all the money, I don't want to spend so much money on my looks. I don't really need dvds. I'll probably donate 100 euros for charity, another 100 goes for clothes, 50 for makeup. So what could I buy with 750 euros that is wise? And I don't wanna save anymore.

I'm sorry if I sound like I'm bragging or something, I'm not. I'm honestly poor but just been saving up.

Added (1). Ariadni: like I said I don't prefer saving up anymore.

Why do I keep getting random calls like this?

On my iPhone I keep getting these random calls. I got them on my other phone too. They're sometimes telemarketers offering tax services. I got another call from a "lawyer in New York" threatening to proceed with the "charges" if I did not call back in the next week. Some of them are calls from actual people. If I try to call one back, a real person answers and it freaks me out. A lot of them have accents, too. All the calls are from major US cities, spread out everywhere. There's no pattern other than that.

What is this? Does this happen to anyone else? Is there some sort of secret network? Am I being stalked?
