Samsung phone help

[Migalot]

I have a Samsung Galaxy S20FE.
Two of my contacts, irritatingly, don't have WhatsApp so I can only communicate with them using the standard Messages app. If I need to send them a picture (as i did this morning), it always fails to send. I have cleared the cache, turned off Wi-Fi and switched on "Use mobile data", but it still won't send a photo.
Anyone got a solution?

TIA

Sending a photo via messages is a multimedia function (multimedia messaging service MMS), many phones have this disabled as most of the operators charge circa 50p per picture sent! Same is true if you have a charge cap on the account.

Might be better using email if they are still living in the dark ages

Or uploading the picture to an image hosting site and messaging them the link. Depending on the exact nature of their technical limitations

Thanks guys!

Spoke to a 3 techie (by chance) and he told me to get an App to reduce the photo size to 300kb.

It works!
