Is there coverage at the Angkor Wat temple complex?
Yes. The entire Angkor Archaeological Park — including Angkor Wat, Angkor Thom, Ta Prohm (the Tomb Raider temple), and Bayon — has solid 4G throughout.
Does the eSIM work in Phnom Penh?
Yes. Phnom Penh has excellent 4G across the city including the Royal Palace, Russian Market, and the Tuol Sleng Genocide Museum.
Is there coverage in Sihanoukville?
Yes. Sihanoukville beach area and the island ferries (to Koh Rong and Koh Rong Sanloem) departure points have 4G. The islands themselves have variable coverage depending on the resort.
What currency does Cambodia use?
Cambodia officially uses the riel (KHR) but US dollars are widely accepted and preferred for larger transactions. Most ATMs dispense USD. Change may be given in riel.
Does this eSIM work near the Thailand border for the Poipet crossing?
Yes. The Poipet border crossing on the Cambodian side has 4G. On the Thai side, you'll need a Thailand eSIM.
Do I need to register a Cambodia eSIM?
No. Cambodian SIM cards must be registered against a passport, which means visiting a carrier shop. A Flysimio eSIM is an international data plan with no registration step — install it before you fly and it connects when you land at Siem Reap or Phnom Penh.
What is an eSIM?
An eSIM (embedded SIM) is a digital SIM built into your phone. Instead of a physical card, you scan a QR code and your plan installs instantly — no SIM tray needed.
Is my phone eSIM-compatible?
iPhone XS (2018) and newer, most Android flagships from 2020+, and all Samsung Galaxy S21+ devices support eSIM. Check our compatibility page for the full device list.
How do I install the eSIM?
After purchase, we email a QR code. On iPhone: Settings → Cellular → Add eSIM → Scan QR Code. On Android: Settings → Network & Internet → SIMs → Add eSIM. The whole process takes under 60 seconds.
Can I keep my regular SIM while using this eSIM?
Yes. Most phones support dual SIM (physical + eSIM). Keep your home number for calls and SMS — use Flysimio for data abroad. You control which SIM handles what in your phone Settings.
Is an eSIM better than a tourist SIM card?
For most trips, yes. A tourist SIM card means finding a shop or airport kiosk on arrival, showing your passport, and swapping out your home SIM. An eSIM is bought online, installed at home before you fly, and connects when you land, while your home SIM stays in the phone. A local SIM can be cheaper per GB for long stays of a month or more, and it is the option to choose if you need a local phone number.
Does the eSIM come with a local phone number?
No. Flysimio travel eSIMs are data-only, so there is no local phone number for calls or SMS. WhatsApp, iMessage, FaceTime and other calling apps work over the data connection, and your home number stays active on your regular SIM for calls and texts.
How fast is the eSIM?
You connect to the same local 4G/LTE and 5G networks listed on this page, at the speeds those networks give local customers where you are. 5G works where the network and your phone both support it. Daily plans run at full speed up to the daily allowance and are slowed for the rest of that day; fixed-data plans run at full speed until the data is used.
Does the eSIM include a hotspot (tethering)?
Yes, all Flysimio plans include mobile hotspot at no extra charge. Share your data connection with laptops, tablets, or other devices freely.
What happens when my data runs out?
You can top up data from your account dashboard at any time. Top-ups are applied instantly — no need to buy a new eSIM or wait.
Can I get a refund?
Yes. Full refund within 7 days of purchase, no questions asked, as long as the eSIM is unused or has used less than 100 MB — that allowance means you can install it and check it connects without losing the guarantee. Past 100 MB we still refund in full for verified faults, such as activation details that never arrived or a technical failure on our side. Contact contact@flysimio.com with your order number.
How long is the eSIM valid for?
You have 6 months from your purchase date to activate the eSIM. Once activated, the plan validity period (e.g., 7 days, 30 days) begins counting down.
Will the eSIM work at the airport when I land?
Yes — as long as you installed the eSIM before your flight, it activates automatically when your phone connects to a local network on landing. No Wi-Fi required for activation.
What if the QR code doesn't scan?
If the QR code won't scan, you can enter the activation code manually — we include both in the email. You can also contact our 24/7 support team and we'll resend or manually provision your eSIM.
