Travel is wonderful, I travel all over the United States and World.    However there are some risks with travel like losing a phone or computer, breaking a device, customs inspections, and robbery.

The solution is older than cell phones and computers.   i was taught from a young age to never travel with anything I did not want to lose.   Also since long before I was born taking expensive things, like watches and jewelry often attracts the attention of burglars, robbers and conmen.   Expensive clothing made in your country of origin also identifies you as a "tourist" which usually means you will pay top prices for everything.

The Solution for phones and technology is to leave your primary phone and computer at home and purchase a disposable "burner" phone, laptop or pad before you leave.   The disposable electronics should only have a few emergency numbers programmed in and the laptops or pads should only have basic programs loaded.   For an extra layer of security and backup copies you can upload photos and documents created on your trip to a server or cloud in your home country.

Long chats and personal information should be kept at a minimum because the US and some other nations now want to access and search these devices.

There are many ways to travel safely.   Personally, I travel and then blend in by wearing clothes and fashions used by the people of where ever I travel, I don't wear an expensive phone or any jewelry.   I may take a Tux and Formal Wear but that stays packed along with the cufflinks, buttons, and bow tie.   

The best way to buy inexpensive phones and computers is online or at local retailers here in the United States.   If you do your research you can also buy a phone service plan for the city or nation you are going to visit.   You can also buy the phones and service plans when you get to your destination.   Computers and other electronics are generally more expensive in foreign countries even if they have stores from the United States.

The other major way to travel safely is to travel with Tour Groups and while this may not give you the most free time to explore on your own - you will see a little of everything.   Tour groups have their own advisors, translators and people for questions or customer services.

My last bits of advice are to not spend all your time on your phone so you do no miss what you traveled to see, and also to keep a journal on paper or a device and take notes about what you see, and what you would like to see more of on your next trip to that location.
