Does using SouthESIM data consume more battery in less-developed areas of the Global South?

In remote or mountainous regions, like the Andes in Peru or rural parts of Laos, your phone might indeed work a bit harder to find a stable signal, which can use more battery. To help, try manually selecting the strongest available network carrier in your phone's settings. For example, if you're in Peru, you might lock onto Claro or Movistar. This prevents your phone from constantly searching and helps conserve that precious battery life for your adventures.
