Can I install multiple eSIMs on the same phone?
Yes. Modern iPhones and Android devices support multiple eSIM profiles - typically 5 to 8 stored profiles, with 1 or 2 active simultaneously. You can install eSIMs for different countries and switch between them in settings without removing any.
What should I do if I lose my activation QR code?
You can't really lose it - your QR code is in your order confirmation email, and also in the install pop-up on the website. To reopen it any time before activation, tap "Install eSIM" in your order email, or sign in at esimno.com and go to Profile > My eSIMs > Install. Both show the QR code together with the one-tap install link and the manual SM-DP+ / activation code. Note the install codes are one-time-use: once the eSIM is installed on a device they can't be reused - reopen the installer (My eSIMs > Install) to display a fresh QR if you need one.
Can I get a refund after purchase?
Refunds are not available once an eSIM has been installed or activated - install codes are one-time-use, so an installed eSIM is considered used even if no data has been consumed. If you have not installed your eSIM yet, you can get a refund within 14 days of purchase without giving a reason - just contact support with your order. We recommend reviewing plan details carefully before purchase to avoid any issues.Refund policy
Can I tether or use Personal Hotspot with my eSIM?
Yes. Your eSIMno plan supports tethering and Personal Hotspot at no extra charge. Activate the Personal Hotspot feature in your device settings and connect other devices as you would with any cellular plan. Data used while tethering counts toward your plan allowance.
Will the eSIM work on my iPad?
Yes, if your iPad model supports eSIM. iPad Pro (3rd generation and later), iPad Air (3rd generation and later), iPad mini (5th generation and later), and standard iPad (7th generation and later with cellular) all support eSIM. Installation works the same way as on iPhone.
Do I need to deactivate my original SIM?
We recommend turning off cellular data and data roaming on your original SIM while abroad to avoid accidental roaming charges. You don't need to physically remove the SIM - just disable data and set the eSIM as your primary data line.
Does the eSIM work in rural areas and small towns?
Coverage depends on the partner network's reach in Cambodia. Major cities, tourist areas, and highways typically have strong 4G/5G coverage. Remote rural areas may have weaker signal or fall back to 3G. Download offline maps before heading off the beaten path.
Can I buy an eSIM for someone else as a gift?
Yes. Purchase the eSIM with your own details, then forward your order confirmation email - or share the "Install eSIM" link from it - with the recipient so they can install it on their own phone (the email contains the QR code and the manual SM-DP+ / activation codes). Make sure their device is eSIM-compatible first - installation usually cannot be reversed once completed.
What makes eSIMno different from other eSIM services?
eSIMno offers eSIM plans for 170+ countries on reliable local partner networks. The price at checkout is all you pay - no activation fee or roaming surcharge. Your eSIM arrives by email within minutes and only starts when it connects to a network at your destination; most plans can be topped up in Profile > My eSIMs, and if you haven't installed your eSIM, you can get a refund within 14 days.
Who can I call and text on a voice plan?
Outgoing calls and SMS are unlimited across Europe - that is the calling area, and it is not the same as where the plan gives you data. Incoming calls and SMS go further: they reach you from anywhere in the world, they are free, and they do not use up your allowance. So if someone back home calls or texts your eSIM number, it arrives no matter where they are calling from. If you mainly need to be reachable rather than to make calls, that matters more than the outgoing area.
Will my eSIM work in airports immediately after landing?
Yes - eSIMs typically connect within seconds of switching off airplane mode at the gate. Major airports have strong cellular coverage from local partner networks, so you'll have data before reaching baggage claim. No setup needed at arrival.
Can I keep my WhatsApp number while using an eSIM?
Yes. Your WhatsApp number stays linked to your home SIM, so all your chats, contacts, and groups remain unchanged. WhatsApp uses data (not the SIM line directly) for messages and calls, so it works seamlessly over your eSIMno data.
