Frequently asked questions.
Answers to common setup and buying questions.
Which eSIM should I choose for Cambodia?
Work from the number of days away, then estimate real mobile data use. The cheapest option, 100 MB, rarely lasts a full tourist day of maps and photos, so 'best value' and 'best price' mean the smallest plan that still fits your actual use, not the lowest number. For light use, 3 GB for 15 days at €4.62 is a sensible middle point; for regular browsing and sharing, 10 GB for 30 days at €15.00 leaves more room. Keep large backups on Wi-Fi.
Which networks and technologies are available in Cambodia?
Two network operators are listed: Smart Axiata Cambodia and Metfone Cambodia. Metfone has confirmed 4G/LTE and 5G flags; Smart Axiata's 4G and 5G support is not confirmed in the supplied data. Reception and speed depend on the network your phone attaches to, the device and your location.
Will my phone be able to support this eSIM?
An eSIM card is a virtual SIM card that installs digitally, so confirm your exact phone model and regional variant support eSIM, and that the device is network unlocked. On iPhone, open Settings, General, About and check Carrier Lock; 'No SIM Restrictions' means it is unlocked. Compatible phones vary between Android and iOS models, so check the compatibility guide before you buy.
When should I install the eSIM?
Install over reliable Wi-Fi and keep the instructions offline; an eSIM installs digitally, but treat 'instant installation' as a delivery method, not a timing guarantee. The start of validity depends on the supplied plan instructions, so follow the activation steps for your plan before enabling the line. On arrival, select the travel eSIM for mobile data and apply the roaming and APN settings specified for it.
Can I keep using WhatsApp and receive bank texts?
Your existing WhatsApp account and other messaging apps run over the eSIM's internet connection. Standard SMS and bank verification codes still depend on your regular SIM, your bank and your home carrier. This data-only plan adds no local phone number, so check your home carrier's charges if you leave that line on.
Can I share my data with a laptop?
The listed networks support hotspot. Any device you connect draws from the same data allowance. Automatic updates, video calls and cloud backups during tethering can burn through a fixed allowance quickly. Pause those transfers or use Wi-Fi when you can.
Is the data allowance unlimited or renewed daily?
Each card shows one fixed total allowance for its validity period. It is not unlimited and it does not reset every day. Tethered devices draw from the same allowance, and a longer validity does not add more data.
Does this plan cover travel outside of Cambodia?
No. These plans cover Cambodia only. Arrange separate coverage for onward destinations and check the country list of any regional plan before relying on it. A signal near a border does not prove coverage in the next country.
Can I add more data or extend a plan?
Pick an available plan that covers the extra data and days you need, and follow the instructions for that purchase. Do not assume you can top up an existing plan by a small amount, that it reuses the same profile or that remaining data carries over. Keep the installed profile while you resolve any connection problem.
What should I check if the data does not work?
Confirm you are in Cambodia, the eSIM line is on and selected for mobile data, and the plan still has data and days left. Follow the supplied roaming and APN instructions, briefly toggle airplane mode or restart, then try another spot. Keep the profile installed and have your phone model, location and order reference ready if you ask for help.
How can I avoid using my regular SIM for mobile data?
Set the travel line as your mobile data line and turn off automatic data switching. Keep data roaming off on your regular SIM, and apply any required travel-eSIM roaming setting only to the travel line. Calls and texts on your regular number still follow your home carrier's terms.
Before requesting a refund, what should I check?
Keep the order reference, installation details and a clear description of the problem. Refund eligibility depends on the purchase conditions and whether the plan has been activated or used, so read the applicable policy before ordering. Do not delete an installed eSIM as your first troubleshooting step.
Can I rely on mobile data to display my Angkor pass?
Save the issued pass offline before the visit and keep it openable on your phone. A live connection helps with messages and checking plans, but reception at any single temple is not guaranteed. Entry is separate from your mobile-data purchase.
Using mobile data on a Cambodia trip
Choosing a Cambodia data plan
Sort the airport transfer, keep your Angkor pass saved offline and agree a pickup point before each temple visit, whether you are a first-time tourist or visiting family. The eSIM installs digitally on a compatible, unlocked phone, so you get mobile data in Cambodia without carrying or swapping a physical SIM card.
The 100 MB and 500 MB options are small allowances, enough for little more than maps and messages. For a short stay, compare these data plans online: 1 GB for 7 days at €1.67 against 3 GB for 15 days at €4.62; step up if you plan video calls, YouTube or regular data hotspot use. Affordable means matching the plan to your actual use, not just picking the lowest price.
For a longer trip, 10 GB for 30 days costs €15.00, and a 20 GB option covers the same 30 days for heavier use. Thirty days is not always one month on the calendar, and the shortest validity listed is 7 days, so even a stopover of one day, or 1 day, still buys a 7-day plan, while a trip of 14 days, or 2 weeks, fits the 15-day option. These are fixed prepaid totals, not a monthly subscription; treat 'no contract' as a search term and read the purchase terms before you commit.
Coverage quality varies between the stops.
The listed network operators are Smart Axiata Cambodia and Metfone Cambodia. Metfone carries confirmed 4G/LTE and 5G flags; Smart Axiata's 4G and 5G support is not confirmed in the supplied data. No single operator guarantees the best coverage everywhere, and the service quality and speed you get depend on the network your phone attaches to, the device and your location.
in reach.Angkor Wat, Cambodia
Phnom Penh: know which airport you are landing at.
Check the flight booking for Techo International Airport (KTI) before you arrange a Phnom Penh pickup. Transfers from KTI are not the same as the former city airport, so send the real airport name and flight details to whoever is meeting you.
The airport publishes Airport Express Bus details, with service running daily from 05:30 to 23:30 on two direct routes into the city. Confirm the current departure details, then map the last leg to your accommodation before you leave the terminal.
Save the hotel address and pickup confirmation on your phone. A data-only eSIM carries messages through your existing apps, but it gives no Cambodian phone number for a driver to ring.
Save before you goKTI flight details, the accommodation address and the current airport-bus stop or agreed pickup point.
Siem Reap: confirm where the shuttle drops you.
Siem Reap Angkor International Airport (SAI) is the arrival point; check its current shuttle-bus details and town drop-off before you decide between the shuttle and a prearranged transfer.
Send your host the expected arrival time and ask how to get from that drop-off to the front door. A town-centre stop and your guesthouse may still be one more ride apart.
Download the first night's booking and the transfer confirmation before you fly. Once connected, use messages to settle the last details instead of letting automatic app updates eat the arrival allowance.
Save before you goShuttle details, the town drop-off pin, guesthouse entrance and host contact.
Angkor: keep the pass offline for the early start.
Angkor Enterprise is the official source for Angkor tickets. Check the ticket type that fits your visit and keep the confirmation or issued pass saved offline; buying mobile data does not include entry.
Agree a named temple entrance and a return time with your driver before you walk off. A pin dropped on the whole Angkor area is too broad, especially when a group returns from different paths.
Signal can weaken around stone buildings and on the approach roads. Keep the day's itinerary and ticket available without data, and fix the next pickup while you are still together. More gigabytes will not force a signal at every temple.
Save before you goIssued Angkor pass, the daily itinerary and a precise pickup location for each stop.
