What happens if my eSIM doesn't work abroad?
First: toggle airplane mode on/off, ensure data roaming is enabled, manually select a network in Settings > Cellular > Network Selection. If problems persist, contact your provider: KnowRoaming offers 24/7 WhatsApp support, Holafly has 24/7 live chat, most others respond within hours via email. Having provider contact info saved offline before departure is essential.
