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

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 models sold in mainland China.
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.

Awesome service. I have traveled back-and-forth between the United States and the Philippines and this app has not let me down. I strongly suggest that you check your data roaming option so this way you don’t mess up what you need to do.
