How can I access public Wi-Fi safely while traveling?

While waiting at an international airport, I needed to log into the public Wi-Fi network to check my flight status. The portal insisted on sending an authentication code via SMS before granting internet access. Getting a temporary line from https://onlinesim.io/ saved me from revealing my primary mobile line to unknown networks. I connected right away and kept my personal data secure.
