One for the panel.....In the last while my other half has not received the odd text that i sent, but in the time frame of sending it has received texts that i sent two (2) years before

No recording of these texts was made by either party, they are usually boring run of the mill texts, yet here they are again
We are both with the same mobile network, so i'm wondering if they have been stored on the company's server (naughty, naughty) and are somehow triggered and slip out ? Very strange.......
