Welcome, and may your camino be everything you need it to be.
There are some things you can do to make things easier on yourself:
A good whistle (in case of falls, or if you want to catch the attention of someone nearby for help).
A good phone app with a downloadable map for your camino route ( like both
Wise Pilgrim and Buen Camino).
A SIM card for your phone for while you are walking (if you are not already on an EU plan). Options range from an eSIM you can pre-purchase, to a nano-SIM that tyou can pick up in most airports. Download "Alert Cops" -- which gives you an easy way to access local police if you should ever need it.
If you have the option on your phone, you might want to set up "fall detection" for some spots (You will know them when you see them), especially if you are making steep descents or climbs all alone (it's the descents that are more likely to result in a tumble if there's been a lot of rain, and the loose scree can trip anyone up).
Exercise caution and awareness because as with any other part of the world, there will be opportunists; keep your boundaries, and if you want to walk alone, it's still a good idea for folks to know where you intend to be or to meet up at the end of day.
To protect my personal belongings, I always put my documents, phone and money pack in the foot of my sleep sac at night, and take precious things with me to the showers. It's really *nice* when you get to stay in an albergue that has personal storage space for each person and a key to lock it!
Buen camino.
