Additional information

I have had the attachment limit set to 1MB and this has been working for the last week (since I 1st installed). Today I started getting this error. I also tried changing the limit to 2MB and have the same issue.

I did some testing with sending pics of varying sizes. It seems anything over 800KB does get sent. It doesn't matter what the attachment limit size is.

To rule out a change with my carrier, other than checking online I also tried the default messaging app and Textra. Both were able to send all pics without issue.

Because of that, and that this was working yesterday and nothing has changed (no app or phone updates, no setting changes), this is seeming like a bug. Let me know what other info can help.

What is the file format of the image you are trying to send?

Also, if you weren't able to send an image with the limit set to 1 MB, changing it to 2 MB doesn't make sense. You should set it to 600 kB or even lower.

All images are jpg.

I guess you're right with that but since I can send those same images with other 2 other apps I'm guessing it's not related to that anyway (Textra I have set to 2MB w/o issue).

Have you at least tried changing the limit to any value lower than 1 MB? It will help us to know whether it's a problem with file size limit or something different. Textra isn't a good example here because in the other bug report it was found that Textra compresses images much below the set limit (#45 (comment)).

Ah I see, sorry I misunderstood the need for that test. I just tried 600kb and it did go through.

However something still seems off because this is what T-mobile says about their SMS limits:

All networks restrict the size of MMS. For T-Mobile, the max sending size is 1MB, 3 MB for receiving, and under 3072 x 3072 resolution.

The original size of the image I sent was 818kb and was well below those dimensions.
I also checked with the person I sent the image to when I tested with textra and the size came through unchanged. Not saying I don't believe they would do so with larger pics, but at least with pic sizes under the 1MB limit I have set (and I guess under the carriers 1MB limit?) it seems they are not being resized.

So I guess it boils down to (1) my carrier allows SMS <= 1MB; (2) I can send an 800kb file with Textra and it is received as 800kb (proving the network is allowing this filesize); and (3) I cannot send the same file with Fossify Messenger unless shrinking it.

Is it possible FM is adding some kind of overhead that would kick it above the 1MB limit? (So approx 180kb)

Isn't this a duplicate of #45?

We should keep 'Error code 5' in one place as it's always about the final MMS size.
