Lost SMS/Txt Msgs on iPhone
Are you sure your SMS/Text Messages are gone? Assuming you have iOS configured to keep them, they should be there.

If you're not sure, here is how to check:


Tap on your iPhone Settings
Swipe up until you see the Messages option
Tap on Messages
Swipe up until you see the Keep Messages option. This should show either 30 Days, 1 Year, or Forever.


If it shows Forever you should be okay. Likewise, if it shows 1 Year you may be okay depending on how far back you need to go. However, if it's only set at 30 Days then you're going to be out of luck unless you have backups for the period you need (which you may do if you have a good backup regime in place).

In terms of accessing past messages, may people don't realise they can do this quite easily by using the following procedure:


Open Messages
Tap on your spouse's name
When the messages appear, tap at the top centre of the screen to load more messages. 


NOTE: It's easiest to tap where the Time is displayed. Each time you do this more messages will load. Depending on how far back you want to go, you may need to tap many times to load them all.
