Why can't I send a text to a contact from my I-pad but can send to that contact from my I-phone?

Why can't I send a text to a contact from my I-pad but can send to that same contact on my  I-phone

Are you saying you are successful in sending text messages to Android users from your iPad?  I doubt you can do that as iPad does not SMS, which is what a cell phone does, but iPad is not a cell phone.  The Message App in iPad was designed to let you send messages to other iOS based devices.
There are Apps you can get from the App Store, like TextFree, which will assign a number to your account, but from iPad you can text all your contacts regardless of type of device.  You will however need to let everyone you message with know what number a message would come from as it won't come from your cell number.
