How can I choose between SMS and MMS?

[Kumidan]

When I have to send a message I can only choose a button which says "SMS/MMS" and it is the phone to decide which to send: SMS if the message contains only text, MMS if it also contains any other content.

I want to be able to decide to send MMS even if my message contains only text.
Is there a way to do this? Does exist any app for this?

My phone is a Motorola Atrix4G.

Uh, there wouldn't be any point in sending an MMS message if its just text. MMS is just the same process as sending an SMS except that it uses a different gateway which would allow sending of nontext data. I don't think its even possible because the MMS gateway only accepts media content, not text content

I'm going to Japan and I will rent a SIM card.
SMS -> 160 chars -> 15yen each SMS
MMS -> 0.32yen each packet (128byte = 128 chars)

When I rented Japanese mobiles in the past it was possible to choose between SMS and S!Mail (MMS) even if the message was only text.
I don't see why it couldn't be possible with Android.

Hmm. Now that you mention it. Yes I seem to remember being able to force send something as MMS on my old Nokia.

EDIT:
Tinkered around with my phone. On a Samsung device, you go to Messages>New Message>click on menu button>add subject. This converts it to an MMS message.

I've checked and I can add a subject with my mobile too, but can't realize if it changes from SMS to MMS, by the way I think it should work since SMS doesn't accept subjects.

Thank you.

If that doesn't work, you could simply attach a very tiny image (1x1 pixel) to each of your messages. Crude workaround, but it should work.

Thank you.

My Samsung gives me a small dialog box for a second after adding a subject saying: converted to multimedia message.

Good, it works, I've found out that my mobile gives me the same message, but only if I start writing something into the subject field.

Thanks again
