Questions
What is the best eSIM for Cambodia?
For most trips, 5 GB for 30 days is enough: $6.79 here, against $13.00 at Airalo for the same data (read 1 Nov 2026). It is data only and needs no app: the QR code and a one-tap install link arrive by email. For heavy use there is also a Day Pass: 3 GB a day at full speed. Every brand's price for Cambodia, dated and sourced, is on our comparison page.
Is there an unlimited eSIM for Cambodia?
Yes: our Day Pass is unlimited data, 3 GB a day at full speed and then 1 Mbps with no cut-off, and 7 days cost $23.90 here. Other brands' "unlimited" plans for 7 days: Airalo $27.00 (unlimited with a daily high-speed allowance) (prices read 1 Nov 2026). Read each one's terms: "unlimited" often means a daily allowance at full speed.
Which Cambodia eSIM for a month?
Every one of these lasts 30 days: 3 GB $4.49, 5 GB $6.79, 10 GB $11.79, 20 GB $23.59. The 30 days start when the eSIM first connects to a network there, so you can buy before the trip.
Can I buy a Cambodia eSIM without an app?
Yes. You pay on this page and the QR code and a one-tap install link arrive by email: no app and no account. It is data only, with no phone number, so your home SIM keeps your calls and SMS.
Does the Cambodia eSIM come with a phone number?
No. It is data only: no local number, calls or SMS on this eSIM. Your home SIM stays in the phone for calls and texts (your carrier's roaming rates apply to them), and WhatsApp, FaceTime or Signal calls run over the eSIM's data. If you need a local number in Cambodia, for example for a service that texts a code, buy a local SIM there.
Which Cambodia eSIM for a week or two?
For 7 days: 1 GB $2.79. The 30-day packs cover one or two weeks too: 3 GB $4.49, 5 GB $6.79. Day Pass, 3 GB a day at full speed and then 1 Mbps: 7 days $23.90.
12 more questions
Will WhatsApp keep my number with a Cambodia eSIM?
Yes. WhatsApp stays on your home number: this eSIM is data only and has no number. Leave your home SIM in the phone with its data roaming off, use the Cambodia eSIM for mobile data, and do not re-register WhatsApp.
Is a Cambodia eSIM cheaper than roaming?
Usually, for a trip of more than a day or two. US carriers charge $12 a day for roaming (AT&T International Day Pass, Verizon TravelPass, read 31 Oct 2026) where they cover Cambodia, so a week costs $84. Here 5 GB for 30 days is $6.79 in total.
