This is a significant roaming trap for travelers heading to Tonga! As an independent kingdom, Tonga is absolutely not included in any standard Australian, New Zealand, EU, or US domestic plans. Your home carrier will charge your group extremely high "Rest of World" satellite rates, which can quickly become a budget nightmare. Triply offers a smart, affordable solution to keep your entire crew connected in Tonga without facing those exorbitant unexpected charges.
HELP CENTER
Is roaming free in Tonga with my Australian, NZ, or US SIM card, or should my group use Triply?
