On Guam, your trip length and how you use your phone decide the plan, so match those two first. - **A city break in Tumon:** For three days of light use, such as maps and messages, pick 1 GB for 7 days. - **A fortnight touring Guam:** For 14 days of standard use, with social media, music and some video, pick 10 GB for 30 days. - **A month-long stay:** For 30 days of standard use, pick 20 GB for 30 days. - **Island hopping:** If your trip also takes in other countries, the [Global bundle](/esim/global-117-countries) covers 117 countries, so one eSIM can take you further. The longest plan lasts 30 days, and most plans can be topped up if you need more data. ## Will my eSIM have signal in Guam? GTA Wireless is the network your eSIM joins on Guam, and your phone picks it up by itself. It runs on 4G, which is plenty for maps, Messenger and everyday browsing. There's nothing to set up. Your data reaches the internet through Singapore, a normal setup for travel eSIMs. You can read more on the [IP address help page](/help/ip-address-another-country). Daily plans slow to a fair use speed once you've used that day's allowance, so save heavy video for days when you have allowance left. ## Using your phone in Guam: data tips - **Landing at Antonio B. Won Pat (GUM):** Install your eSIM at home on Wi-Fi before you fly. When you land, switch the eSIM line on, then [turn on data roaming](/help/turn-on-data-roaming) for it. - **Finding your way:** Before you head out, type Tumon, Hagåtña, Tamuning or Dededo into your maps app and save the route. Your eSIM connects to GTA Wireless's 4G network. - **Data, plainly:** Light use, such as maps, messages and email, is about 0.25 GB a day. Heavy use with streaming and hotspot is about 1.8 GB a day, and most plans can be topped up. - **Staying in touch:** Messenger is the messaging app to have ready here. Your home number stays on for calls and texts, and the [WhatsApp steps](/help/keep-whatsapp-and-home-number) show how to keep WhatsApp going too. - **Going further:** The Global plan covers 117 countries, Guam included, so it's worth a look if your trip continues. ## Questions ### How much is an eSIM for Guam?

Yes. Most Guam plans can be topped up from your eSIM page in two taps, with no new QR code. The plan table on this page shows which ones. ### Why does my IP address show another country? Guam plans route your data through Singapore, a normal setup for travel eSIMs. Websites and apps may show that country's content; your speed and coverage in Guam are not affected. ### Does it come with a phone number? Every eSIMology plan is data only. Keep your own SIM switched on for calls and texts, and use WhatsApp, FaceTime or any calling app over your eSIM's data. ### What if my plans change?
