Frequently Asked Questions
What is the cheapest eSIM for Guam?
Guam is covered by multi-country plans only, and the cheapest is $12.99 for 1 GB, valid for 30 days. Prices come live from 2 vetted providers and change often; the price on this page is the current one.
Is it worth getting an eSIM for Guam?
For most travellers, yes, if your phone supports eSIM. Guam plans start at $12.99 for 1 GB, and the longest lasts 365 days, which suits long stays and repeat visits. If your home plan already covers Guam at no extra cost, you may not need one.
Which networks do Guam eSIMs use?
Every Guam eSIM on MobiMatter connects to Docomo, so your coverage is that network's coverage. If you are heading somewhere remote, check its coverage map before you buy.
Which eSIM is best for Guam?
No plan covers Guam alone right now, so the choice is a multi-country plan. The top one is 12 GB for 30 days at $22.99 from Three Hong Kong, covering 21 countries. We rank plans on quality and value for money.
How much data do I need for a week in Guam?
It depends on how you use your phone. Light use (maps, messaging, browsing) takes about 0.5–1 GB a day; scrolling a lot of social video can take 2–3 GB or more. Typical use per hour:
- Instagram Reels, TikTok: 0.3–1 GB
- YouTube, Netflix at standard quality: 0.5–1 GB
- Video calls (WhatsApp, FaceTime): 0.5–1 GB
- Voice calls (WhatsApp, FaceTime Audio): 50–70 MB
- Maps and navigation: 2–6 MB
- Messaging and browsing: 50–150 MB
The cheapest Guam plan with at least 5 GB for a week or longer is 7 GB for 30 days at $13.99.
Do Guam eSIMs support 5G and hotspot?
Guam plans currently run on 4G/LTE. Hotspot (tethering) works on every plan, so you can share your data with other devices.
Does a Guam eSIM come with a phone number?
Most travel eSIMs, including most Guam plans, are data-only and have no local number. You keep your usual number on your main SIM for calls, texts and WhatsApp. Plans that include a number or minutes say so on the plan page.
Will my phone work with a Guam eSIM?
Yes, if it supports eSIM and is not locked to a carrier. To check, dial *#06#: if an EID number appears, your phone supports eSIM. Most iPhones from the XS/XR on, Galaxy S20 and later and Pixel 3 and later do, except most models sold in mainland China and some sold in Hong Kong and Macao.
Can I keep my own SIM and WhatsApp while using a Guam eSIM?
Yes. Your eSIM and your main SIM can be active at the same time. Use the eSIM for mobile data with data roaming on for that line, and turn data roaming off on your home SIM to avoid charges. WhatsApp keeps working on your usual number.

I used it for the first time with my wife during our trip to Japan and Korea, and I didn't experience any connection problems. The internet was fast enough in both Japan and Korea, and I was satisfied with the app. I recommend it.
