Sending text messages on its own?

[Pappeh]

Hey everyone,

My wife's iPhone SE sent off like...30 of these text messages today all in rapid succession. The text contained is Jiberish and all of the numbers are a slightly variation on these ones. Anyone seen this before?

Looks interesting. About 30 Chinese people will likely be wondering why they are receiving a message from your wife.

Simplest way to (hopefully) stop it happening again is to go to Settings/Reset/Reset All Settings.

And for good measure, clear Safari website data too.

I suspect a script from a website sent the messages. There are no viruses for iDevices so you can rule that out.
