Which network actually works in Tonga
Digicel Tonga is your best bet for an eSIM before you even land. Their network covers most of the main island, Tongatapu, and the popular outer islands like Vava'u. Don't expect lightning speeds everywhere, though. Rural areas and smaller, less populated islands might see coverage drop to 3G or even just edge.
For a plan, you're looking at around $15-$25† for 7-15 days with 5-10 GB of data. You can often buy these directly through Digicel's website or app. If you buy an eSIM from a global provider like Airalo or Holafly, check carefully which Tonga network they use. Sometimes they route through less reliable partners.
Activating can be fiddly. Make sure you're not on airplane mode when you scan the QR code. Some phones, especially dual-SIM models from China, can have issues with eSIM recognition. You usually have about 15 minutes to scan and install the eSIM after purchase; don't leave it until you're on the plane.
Here's the real Tonga gotcha: data is expensive, and speeds can be slow. It’s not like Southeast Asia where you get 50GB for $10. Be prepared to ration your data or look for Wi-Fi at your accommodation. Hotspotting from your phone is generally allowed, but heavy usage might get throttled.

Your bank’s 2FA codes still arrive on your physical SIM. Don’t pull it out, just disable data on it in settings.
One eSIM per trip, not per country
