Validity of text messages

[Anonymous]

How do you change the validity of a text message sent. I got a report saying message expired after 48 hours because recipient didn't have their phone on. Can it be extended?

I think it can on some phones.

Somewhere in the settings you can change the message validity to 'MAX' which is 30 days.

'IF' apple let you.

Not sure if this will be of any use to you, but I use a code that's been around for years and yes it works with the iPhone.

At the very start of your text message type *0# then leave a space and continue writing your text message and send.

You will get a text back saying that message to number blah blah blah was delivered, it will also show date and time it was delivered.

Delivery does not mean that the message has been read though. It just indicates that their phone will have received the message.
