Discuss what they need to consider if they wish to use their devices when they are away from home?

Below are suggestions Ryan and Michael should be aware or when travelling away from home with portable personal digital devices.

Portability: This includes the size and weight. Always keep portable equipment like phones and laptops in your possession every time.

Power adapters or chargers: At one point, you will need to recharge your phone or laptop. Bring your charger, plug adapter or a voltage converter if traveling overseas.

Mobile networks or Data roaming charges: When traveling overseas, it is worth noting that your data plan will probably be very expensive. Be sure to turn off 3G and push services and disable notifications.

Connectivity and availability of the internet: Doing a research on the connectivity well before your departure date is vital. Ensure to find out whether free wireless is offered at your hotel. If you must connect to any public hot-spots, be careful not to enter personal information like passwords and credit cards numbers.

Personal security and the security of the device: If you are set to travel to a dangerous part of the world, leave your expensive electronics behind and find alternative ways of how you can stay in touch with family and friends
