The sums assume data every day at 0.8GB a day, the same norm as the data calculator; highlighted is the option that costs least. We compare each network’s public roaming passes and daily rates. Some plans have roaming built in (for example Vodafone Global Roam, O2 Ultimate, Three Complete and Sky Diamond VIP), so check your own plan. Network prices as published for their own customers; the eSIM at its price in pounds on 1 Nov, charged in pounds by card. For other days or other usage, work out your own trip. Every destination: roaming or eSIM, by country.

Frequently asked questions
Which network does the eSIM use in Guam?
Only GTA (4G): it is the single partner network for Guam in the catalogue. Where GTA has no coverage, this eSIM has no signal either, so on a remote route check that GTA covers it.
What if the eSIM doesn't work when you land in Guam?
Check, in this order: data roaming is on for the eSIM line, the eSIM is chosen as the line for mobile data, and aeroplane mode is off. Then the APN: on this plan it is entered by hand on Android, mpulse.gta.net. Give the phone a few minutes to register on GTA; that first registration is what starts the plan’s days. Still no connection? See what to check when the eSIM has no signal abroad.
General questions have their own pages: how card payment works, refund policy, how to install an eSIM and help and FAQ.
Prices come from our partner operator’s catalogue and may change; the amount at the moment of payment applies. We are not a mobile operator: network access is provided by the partner operator, under the plan’s terms. See the terms and the refund policy.
