Can iphones only send sms text through data?

I recently got am iphone 5s and it ended up not working so maybe that was the problem. But I noticed that I could not send messages to android users without my data on? Is that how apple works or was it just that phone.Also, I did try sending it with Wi-Fi on and it still would not work.

It's because your imessage settings are wrong. Use another SMS service.

No phone requires data to send SMSs.

  • ON IPHONE, How do i send a text a email address as a SMS and not MMS? On my basic phone, I can text a email address without it being MMS. Now on my iPhone, it only can text email addresses using MMS. This requires data. Does apple IPHONES not know how to text a email address? I don't want to use data to text email address? I might as well just use email.
