How to verify eSIM support on your device

1. iPhone: Settings → Cellular → look for "Add eSIM" or "Add Cellular Plan". You can also dial *#06# , if you see an "EID" (32-digit number), your phone has eSIM hardware.
2. Android: Settings → Connections (or Network & Internet) → SIM Cards → look for "Download a SIM instead" or "Add eSIM".
3. EID check: most eSIM-capable Android phones show EID in Settings → About Phone → Status.

Tip: Even if your phone supports eSIM hardware, it must be unlocked (not carrier-locked) to use third-party eSIMs like Cellesim. Most phones bought outright are unlocked; phones from carrier instalment plans may require unlocking after the contract is paid off.

Almost every flagship smartphone released since 2019 supports eSIM, making it ideal for international travel. Compatible models include iPhone XS and newer, Google Pixel 3 and newer, Samsung Galaxy S20 and newer, plus a growing list of mid-range devices. If your phone has Settings → Cellular → "Add eSIM", you're ready to use a Cellesim plan abroad.

Travellers benefit most from eSIM because it eliminates the airport SIM-card queue, removes the need to swap your home SIM out, and lets you keep your usual phone number active for SMS verification. A Cellesim travel eSIM activates the moment you land , no shop visit required.

4. Android version: Android 9 or newer typically supports eSIM, though it depends on the manufacturer.
5. Region-specific variants: some Samsung models sold in Hong Kong or China are dual physical SIM with no eSIM , verify your specific model number.

Tip: if your current phone doesn't support eSIM but you travel often, an unlocked, mid-range eSIM-capable phone (e.g., Pixel 7a, iPhone SE 3, Samsung Galaxy A55) makes an excellent secondary travel device , pair it with a Cellesim plan and you have a full mobile internet kit for any destination.

Warning: Check your plan carefully! Although Guam is a U.S. Territory, most U.S. carriers do not include it in their standard "domestic" plans. You may be charged high pay-per-use roaming fees ($3+/MB) or be throttled to unusable 2G/3G speeds. A Cellesim Guam eSIM connects you to the fastest local 4G/5G networks (like GTA or Docomo) for a fixed, cheap price, saving you from a massive bill. 

 To give you the best speed on the island, our eSIM connects to Guam’s top-tier providers, typically GTA Teleguam, Docomo Pacific, or IT&E. This ensures you get the fastest and most reliable 4G/LTE (and 5G) coverage, whether you are in the tourist hub of Tumon or at Naval Base Guam. 

 This specific plan is valid only within Guam. Many travelers (especially military personnel or divers) "island hop" between Guam and Saipan (CNMI). These are separate territories with different network agreements. If you plan to visit both, you will need a separate plan for CNMI or check our Pacific Regional eSIM options. 

Yes. While Guam is a small island, coverage can be spotty in the dense jungles or southern villages. Our eSIM connects to the strongest available signal, providing reliable coverage not just in the Tumon and Tamuning tourist districts, but also at popular spots like Ritidian Point, the Two Lovers Point lookout, and in villages like Merizo. 

Yes, for convenience and speed. Buying a physical "prepaid" SIM at the Guam Airport (GUM) requires you to find the kiosk (which may be closed if you land late), present your passport, and go through the registration process. Our eSIM is 100% digital. You can buy it online, install it before you fly, and be connected the moment you land, ready to use Google Maps or contact your hotel. 

 Most modern phones do, but you must check our specific list here: eSIM Compatible Devices to be 100% sure before purchasing. 

 No, Uber does not operate in Guam. You need reliable data to download and use Stroll, the local ride-sharing app, or to find taxi dispatch numbers on Google Maps. 

 Yes. Coverage is generally reliable on the major military installations like Andersen AFB and Naval Base Guam, allowing you to stay connected with family off-island. 

 Absolutely. Public transport is limited, so most visitors rent cars. Reliable data for Google Maps is vital to navigate Marine Corps Drive and find hidden spots like the Inarajan Pools. 

 Yes. You will have strong signal at the Two Lovers Point observation deck, allowing you to live-stream the stunning views of the Philippine Sea instantly.
