How do I force send a text message in iOS 10?

When I'm out of the country and don't have wifi or data and I want to send a text message to another iPhone back in the UK, it won't let me send a standard text message . It wants me to send an iMessage as it recognizes I'm sending to another iPhone , but I do not have any data allowance or wifi so it won't let me send an iMessage anyway, and I can't find a way for forcing it to send a text SMS message.

I've looked in settings and turned off my iMessage, and the option to send text SMS only is not there anymore. I used to be able to do this before iOS 10. Is there a way I can send a standard text?

Solution 1:

Go to settings and turn off iMessage. Send your message. (Optional) go back to settings and turn iMessage back on.

Solution 2:

Solution 3:

You can, press and hold the unsent iMessage and a menu will pop up with the option
