Re: why can i not send photo's when i text.
You also need to make sure that the total message size, text plus pictures, is 1MB or less.
More than that, use email, up to 25MB.
Still larger? Post the picture on a cloud account and email a link to it. (There's no limit there - I've downloaded 3GB files from Mega, and a picture like that would be a close-up of the White House Lawn good enough for you to pick out the mites on the legs of the insects in the grass while seeing the whole lawn.)
