Iphone doesn't have any options to turn on receipts for SMS but I have seen other phone networks allowing you to prefix your text message with a code to receive the receipt.
For example prefix a text message from o2 with *0# and you'll get sent a delivery receipt.
Does id have such a code to request a receipt?

Unfortunately it would seem that iD Mobile don't support this feature yet :(
iPhones also unfortunately don't support the feature to toggle on "Get SMS Reports" or "Request Delivery Report" either. They kinda scrapped this after iMessage became a thing which is weird how they give the option of delivery/read receipts to iMessage but not SMS messages.
