My iphone 4 will not send my text. I have gone through all the fix steps in setting an it still will not send my text

go to setting, messages, try to turn off imessage for few seconds , then turn on, if still doesnt work, signout of apple id & sign in again

for sms, in the same messages there is a toggle which u need to make on which says "send as text message"

Okay, and you worked through this page: https://support.apple.com/en-us/HT204065 ?

Is iMessage activated? https://support.apple.com/en-us/HT201422

Are you sending a message to another iPhone or to an Android phone?

Does this phone currently have an active phone number?

Does this phone have an active phone number?

What does your iPhone show when it tries to send? "Not Delivered" or something else?
