How much data do you need in Guam?
Maps, messages and some browsing use about 0.3–0.5 GB a day. Add social media and photos and it is closer to 1 GB a day; video calls and streaming use much more.
| Weekend, light use | 1–3 GB |
|---|---|
| One week, normal use | 3–5 GB |
| Two weeks, normal use | 5–10 GB |
| A month, or working remotely | 10–20 GB |
Can I keep my WhatsApp number?
Yes. WhatsApp and iMessage stay linked to your usual number; the eSIM only carries the data.
Do I need to remove my own SIM?
No. Phones that support eSIM run it next to your normal SIM. Turn off data roaming on your own line so it doesn’t charge you.
