Re: Receiving/Sending of texts is delayed
The iPhone uses data to send text messages between iPhones. hence why some messages are blue, and other messages are green when you send to other types of phones. This could be one reason you had zero lag with iPhone if the majority of your friends have iPhone as well.
If you are experiencing this across phones and carriers it is a problem with your area. you would need to contact your current carrier for a resolution. Your phone isn't the problem they are.
