Provider-by-provider breakdown
Superalink is the clear starting point — cheapest for a genuine week (1GB/7 days at $3.00), and also the best unlimited option once you scale up, at $15.68 for 5 days or $46.74 for a full month. If you're not sure how long your trip is or how much data you'll actually use, Superalink is the sensible default to check first.
BNESIM takes over as the best value for a longer stay, at $3.02 for 1GB/30 days — and it's also the strongest raw price-per-GB in the whole catalog, with a 100GB/30-day tier at $100.84 for anyone who needs genuinely heavy data volume. They currently run a real discount code too:
eSIMGlobe (from currently unavailable for 500MB/1 day) has one of the largest single lineups we track for Guam — useful if your trip length doesn't line up with anyone else's standard tiers, and they currently have a discount code active as well:
Yatelo (from $4.73 for 1GB/7 days) and Revo eSim (from $5.53 for 1GB/7 days) both sit in the middle of the comparison — worth a look if their specific tier shapes happen to fit your trip better than the leaders above.
AirPlans offers a strong short-stay unlimited option in the catalog at $50.06 for 3 days — a strong pick if you're passing through Guam on a shorter connection rather than staying the full week. They also currently run a discount code:
10% off any one order, no minimum. One use per customer — first order or fifth.
nadanada (from $6.99 for 1GB/7 days) and Sim Local (from $7.50 for 1GB/3 days) round out the mid-tier options — reasonable fallback picks if your first-choice provider's network happens not to perform well in a specific part of the island.
Why prices vary this much
A cheap weekly plan and a bulk-data month both show up under "Guam eSIM," but they're solving different problems. Superalink and BNESIM both compete hardest on efficient, fixed-data pricing sized for a real trip length. BNESIM's real strength beyond that is bulk-data pricing specifically — its 100GB tier is priced efficiently for genuinely heavy users (remote work, hotspotting, large uploads), which is exactly why it wins on price-per-GB without being the absolute cheapest entry tier. AirPlans and Superalink take a different approach for unlimited buyers, pricing by the day or in short blocks — useful specifically for a shorter Guam stopover rather than a full week or month.
If you're not sure how much data your trip actually needs, our data usage guide is worth a look before defaulting to a bigger plan than necessary.
Which plan fits your trip
- A short stopover or a few days on the island: AirPlans' 3-day unlimited plan at $50.06, or Superalink's 1GB/7-day plan if a week fits better.
- A standard week in Guam: Superalink's 1GB/7-day plan at $3.00 is the clear default pick.
- A longer stay or a full month: BNESIM's 1GB/30-day plan at $3.02, or its 100GB variant at $100.84 if you need real data volume for remote work or heavy uploads.
- You want unlimited data without thinking about it: Superalink's day-rate for a short trip, or their 30-day unlimited at $46.74 for a full month.
A few practical notes
As a US territory, Guam's mobile infrastructure is generally solid around the main population centers like Tamuning and Hagåtña, though — same as with a local Guam SIM — coverage can thin out in more remote parts of the island. Install your eSIM before you fly; every provider above activates only once you land and connect to a local network, so there's no benefit to trying to set it up in advance.
If this is your first time using an eSIM, our beginner's guide to how eSIMs work covers installation and activation from the very start, and it's worth confirming your phone is eSIM-compatible and carrier-unlocked before you buy.
If Guam is a stopover on a wider Pacific or Micronesia itinerary, check each destination's own pricing separately rather than assuming one plan carries over — our multi-country trip planner can show you real plans that genuinely cover your full route if one exists.
Guam also sees a lot of visitors from Japan and South Korea, and English is widely spoken alongside Chamorro, so day-to-day connectivity needs here look a lot like a domestic US trip — booking apps, maps, and messaging rather than needing a local phone number for calls.
