Networks and coverage in Guam

Your eSIM connects to GTA Wireless (4G). 4G. That's plenty for maps, messages, social media and video calls.

Real speed depends on the local network, how busy it is and your signal. Why 5G or 4G

How to set up your Guam eSIM before you fly

  1. Check your phone. It needs eSIM and no carrier lock. Dial *#06#: if you see an EID, it supports eSIM. Phone check
  2. Install at home, on Wi-Fi. Any time up to 180 days before. Your days don't start until it first connects in Guam.
  3. When you land, switch the kimsim line on and turn on Data Roaming for it. You won't be charged roaming: kimsim is prepaid. Keep roaming off on your home line.
  4. Make kimsim your mobile data line. Your home number stays on for calls and texts.

Guam eSIM: questions travellers ask

Which network does the Guam eSIM use?

A kimsim Guam eSIM connects to GTA Wireless (4G). It does this on its own once Data Roaming is on for the kimsim line, so there's nothing to choose.

Does the Guam eSIM work on 5G?

Not at the moment: these plans run on 4G (GTA Wireless (4G)). That's plenty for maps, messages, social media and video calls. Real speed depends on the network, how busy it is and your signal.

How much data do I need for a week in Guam?

Many travellers use around 3 to 7 GB a week for maps, messages and some social media. For a typical week, the 10 GB pack is a sensible start, and you can top up onto the same eSIM. If you stream or use hotspot every day, Unlimited suits you better.

Is there an unlimited data eSIM for Guam?

Yes. kimsim Unlimited gives you 3 GB at full speed every day, then 1 Mbps for the rest of that day, which is fine for messages, maps and music but not HD video. Pick how many days you need; the allowance resets daily.

Can I use my Guam eSIM in other countries?

An eSIM for Guam works in Guam only. For a trip that goes further, Global (117 countries) cover Guam and more countries on one eSIM. Check every country on your trip is on the plan's list before you buy.

When should I install my Guam eSIM?

Before you fly, at home on Wi-Fi. You can install it any time up to 180 days ahead. Your plan's days only start when the eSIM first connects in Guam, so installing early costs you nothing and means you're online when you land.

Do I need to turn on data roaming for an eSIM in Guam?

Yes, for the kimsim line only. The eSIM connects to local networks as a visitor, so your phone treats it as roaming and won't use it unless roaming is on. You aren't charged roaming: kimsim is prepaid. Keep Data Roaming off on your home line.

Does the Guam eSIM come with a phone number?

No, kimsim plans are data only. WhatsApp, iMessage, FaceTime and other apps keep working on your usual number over data. Your home SIM can stay on for normal calls and texts, such as bank codes, at your home carrier's rates.

What if my Guam eSIM doesn't work when I land?

Check the kimsim line is on, Data Roaming is on for it, and it's your mobile data line. Then restart the phone. Still nothing? Don't delete the eSIM: contact us with your order number. If it can't be activated and we can't fix it, you get a full refund.

Can I top up my Guam eSIM?

Yes. Top up from My eSIMs onto the same eSIM, with nothing to reinstall. It's handy if you picked a pack that's too small or your trip gets longer.
