Jessica is a Staff Writer for WhistleOut and the site’s resident app expert, covering mobile plans, carrier pricing, smartphone deals, and the mobile apps that power everyday connectivity. She tracks plan changes and promotions across major carriers and MVNOs while testing a wide range of apps to help readers determine which downloads are genuinely useful, and which ones just take up storage space. Her coverage frequently includes hands-on comparisons of popular app categories, such as translation, navigation, and dating apps, to evaluate how they perform in real-world mobile use.
After spending six years teaching abroad, Jessica developed a global perspective on connectivity that informs her expertise in international phone plans, eSIM carriers, and the apps travelers rely on to stay connected across borders.
She currently uses an iPhone 11 on Visible’s base plan and regularly experiments with new apps to identify the most helpful tools for everyday mobile users. Her current favorites include Splid, Garmin, Discord, and Libby. When she’s not researching wireless trends or testing the latest apps, Jessica enjoys cycling and open-water swimming.
