Network & Coverage

Stay connected across every corner of Guam

Your eSIM connects to the local network of GTA Wireless — for fast, reliable 4G/5G from the resort strip and white sands of Tumon Bay and the Spanish-era Plaza de España in Hagåtña to the clifftop Two Lovers Point and the wildlife refuge at Ritidian Point.

GTA
Guam's homegrown network, delivering fast, reliable 4G/5G across Tumon, Hagåtña and the whole island.
Popular destinations covered

From relaxing on Tumon Bay and exploring the Plaza de España in Hagåtña to taking in the view from Two Lovers Point or snorkelling at Ritidian, your unlimited data keeps maps, translation and ride-hailing apps running wherever Guam takes you.

Will my Guam eSIM work across the whole island?+
Yes. Your eSIM runs on Guam's main networks (GTA), which provide strong 4G/5G island-wide — from the Tumon resorts and Hagåtña to Dededo, Yigo and the southern villages. Coverage is excellent across Guam.
Can I share my Guam eSIM as a hotspot?+
Yes — tethering is fully supported, so you can share your unlimited connection with a laptop, tablet or a travel companion's phone — perfect for working from a Tumon Bay café or keeping the group online on an island road trip. One thing worth knowing: hotspot traffic counts towards the same 2 GB daily full-speed allowance, and tablets or laptops get through it faster than a phone. If you plan to keep several devices online all day, one of our data packages with a fixed GB volume is usually the better fit.

Frequently asked questions

Everything you need to know about your Guam eSIM

Is the data truly unlimited? +
Yes — there is no data cap and your connection is never switched off. Like every unlimited travel eSIM, the plan carries a daily full-speed allowance: in Guam that is 2 GB per day. Beyond it you stay online at a reduced speed (1 Mbps) for the rest of that day, and full speed returns automatically the next day. Hotspot traffic counts towards the same allowance. We publish the exact figure for all 181 destinations — see our daily allowance by country.
When does my eSIM activate? +
Your eSIM activates the moment you first connect in Guam. Your days don't start until you're there — so you can install it weeks before travel with no waste.
Which devices are compatible? +
Any unlocked eSIM-compatible device: iPhone XS and later, Google Pixel 3+, Samsung Galaxy S21+, and most modern Android flagships. Check Settings → Cellular → Add eSIM to confirm.
How do I install the eSIM? +
After purchase, check your email for the QR code. On your phone: Settings → Cellular (or Mobile Data) → Add eSIM → Scan QR Code. It takes under 2 minutes. Full step-by-step instructions are included in the email.
What if I need help? +
Our team is available 24/7 via live chat at aerosims.com — day or night, before or during your trip.
Could my internet speed ever change? +
Yes — once you pass the daily full-speed allowance, which in Guam is 2 GB per day. After that, data keeps working at a reduced speed (1 Mbps) for the rest of that day and returns to full speed the next day. Nothing is cut off, and hotspot traffic counts towards the same allowance. This tier is set by the local operator, not by AeroSims. Full details for every destination: daily allowance by country. If you prefer a guaranteed volume at full speed, our data packages give you a fixed number of GB.
Can I extend it if I stay longer? +
Often yes. While the eSIM is still active, open your personal eSIM page — the link is in your delivery email — and you will see there whether extra days can be added to your plan. If they can't, another eSIM for the same destination arrives by email and installs alongside the one you already have.
