Guam and US eSIM

Operators are listed with 5G, but not every country or operator has 5G. Each plan's networks show them by country.

It depends on which plan you pick: others drop to 128 Kbps, which is enough for messaging; a few stop passing data altogether. Every row says which.

It starts when the eSIM first connects to a network, not when you buy it and not when you install it.

No. Each QR code installs once. If you delete the eSIM or reset the phone, it can't be installed again, and once it has connected to a network it can't be refunded. Install it on the phone you're travelling with.

It depends on the plan: some can add data within the current validity, some can add days, and some can't be topped up. The plan shows which before you buy. To top up, open the eSIM in My eSIMs or on its order page and choose an option; it goes onto the same eSIM, so there's nothing new to install. If no options are shown, buy a new plan.

Yes. The listed price is the final price, with no activation fee.
