Here is the accommodation information:
Single room, no breakfast.
It costs US$9 per night, but I paid 25 soles, which is about 900 yen.
I brought my motorcycle inside, but there are stairs, so I had to carry it up with the help of a man. Ugh.
In this first town in Peru, I bought a smartphone. It's a Moto E. I'm not sure if it's the 1st generation or the 2nd generation, but it cost about 16,000 yen (439 soles). The original price was 479 soles, but I couldn't understand the "7" displayed, so I thought it was 3, but it was actually 7. And then, when I was about to pay, they said, "If you pay with a credit card, there's a 5% surcharge" (which should be prohibited according to the regulations). So the total would be a little over 500 soles (about 19,000 yen), and I hesitated, and I was about to say, "I'll pass," but just then, the person on the phone finished talking to their boss, and they said, "Okay, I understand. 439 soles. You can pay with a credit card at that price." So I ended up buying it for about 16,000 yen. I had confirmed online that it was being sold for 399 soles (about 15,000 yen), so I thought I could buy it if it was only about 1,000 yen more, so 439 soles was probably still profitable for the store.
The Android One phone I had was cracked, and it seems I couldn't use the cheap SIM cards here with it, so I decided to buy a new one.
After that, the store employee sold me a SIM card called "bitel," which is supposed to be only available to Peruvian residents, using his name. It's an unlimited 30-day plan for about 1,300 yen. Normally, 1GB costs around 2,000 yen, so this is a very good deal.
Mobile communication in Ecuador is quite expensive, but it seems I can get it cheaper in Peru.
■ Postscript (11/14):
The Moto E I bought recently received an update, and when the Android OS updated to 5.1, I suddenly ran out of storage space. It's so tight that I can't even install essential apps. So, I had no choice but to root it and uninstall all the pre-installed apps to free up space.
Rooting voids the warranty, but that doesn't matter since I'll be leaving Peru anyway. I haven't rooted a phone since I tried it on the XPEDIA 1st generation, but it seems that the "rooting using OS bugs" method is no longer available, and the mainstream method is now rooting directly from the bootloader. Well, that's fine. There's plenty of information available, and I was able to set it up pretty quickly. I wonder if a lot of people will customize Android and have fun now that it's so easy. As expected, there are various custom OSes available. This Moto E is a cheap phone, so it seems to be a popular toy for people who like to modify it, and I'm glad there's a lot of information available. I think it's less likely that a simple mistake in commands or settings will cause the phone to stop working and become a paperweight, like it used to.
