Specimen messages are written for this pack and modelled on the patterns official bodies describe. They contain no real person's details and the links point nowhere real, so they are safe to show on screen.

1. Grandma it's me, I've had an accident and I'm at the police station. Please don't tell Mum. Can you send money for bail now? I'll explain later.

2. Hi Dad, I dropped my phone in the sea, this is my new number. I need to pay a bill urgently, can you help today?

3. This is Officer Daniels. Your son is in custody after a car crash. Bail is $3,000 in gift cards. Do not hang up.

4. Mum, it's me. I'm stuck abroad and my cards are blocked. Please send $900 to this account and keep it between us.

5. Hey it's your nephew, voice note won't send properly. Can you transfer $500? I'm embarrassed to ask anyone else.
