Guam eSIM prices at a glance

SoloSim sells 15 prepaid eSIM plans for Guam, priced from $5.50 to $91.40 and valid for between 1 and 30 days. The smallest is 500 MB / day for 1 day at $6.40; the largest is 20 GB for 30 days at $91.40. The best value per gigabyte is the 10 GB / day for 1 day plan, which works out at $4.29 per GB. 9 of the plans are daily allowances — the data resets every 24 hours instead of being a single balance for the trip.

Network and speed in Guam

Every Guam plan connects over 3G/4G/5G networks. 9 of the plans slow down rather than stop when their allowance is used up: they drop to 512 Kbps, 1 Mbps or 384 Kbps for the rest of the validity period, so maps and messaging keep working. Traffic exits to the internet through SG, which is the location websites and apps will see you connecting from.

Which Guam plan for your trip?

  • A long weekend (up to 3 days): 1 GB for 7 days at $5.50.
  • Two weeks: 3 GB for 15 days at $14.70.
  • A month: 3 GB for 30 days at $15.60.

Plans are prepaid and data-only, so if you run low you top up from the app rather than paying overage.

How it works

  1. Pick a plan and pay online — no account or physical SIM needed.
  2. Scan the QR code we send you to install the eSIM on your phone. Check your phone is eSIM compatible.
  3. Turn on data roaming for the eSIM when you land and you're online.

Guam eSIM — frequently asked questions

How much does a Guam eSIM cost?

Guam eSIM plans on SoloSim start at $5.50 and go up to $91.40 for the largest plan. Prices are in USD and include everything — there is no activation fee and no roaming charge on top.

Does the Guam eSIM support 5G?

Yes. All plans for Guam connect over 3G/4G/5G networks, and your phone will use the fastest one available where you are.

How long is a Guam eSIM valid?

The validity period starts when the eSIM first connects to a network in Guam, not when you buy it, so you can install it at home before you fly. The longest Guam plan currently lasts 30 days.

What happens when I use all the data on my Guam eSIM?

Plans with a fair-use policy slow to 512 Kbps, 1 Mbps or 384 Kbps for the remainder of the validity period instead of cutting off. Top up from My eSIMs in two taps — added data shares the current expiry date. With low data alerts on, we warn you at 80% and 95%.

Can I keep my own number while using a Guam eSIM?

Yes. The eSIM carries data only; calls and texts keep working on your home SIM. Just make sure data roaming is off on the home line.

How do I install the Guam eSIM?

After purchase you get a QR code. On Wi-Fi, scan it from another device (or use the one-tap link on the same phone), then enable the new data line in Settings.
