How do I delete an eSIM I no longer need?
On iPhone: Settings > Cellular > tap the eSIM line > Remove eSIM. On Android: Settings > Network & Internet > SIMs > tap the eSIM > Erase. Deleting the eSIM frees up a profile slot. Make sure you don't need it anymore - once deleted, you can't reinstall the same profile.
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.
What makes eSIMno different from other eSIM services?
eSIMno partners directly with local operators in over 200 countries, eliminating intermediaries. This direct relationship lets us offer competitive pricing, extensive coverage, and faster activation than resellers who route data through third parties.
Can I use the eSIM to make video calls?
Yes - apps like FaceTime, WhatsApp, Zoom, Google Meet, and Microsoft Teams all work over your eSIM data. Video calls use about 200-400 MB per hour depending on quality, so factor that into your plan choice if you make long calls regularly.
How fast does the eSIM activate after I switch off airplane mode?
Activation typically takes 10-30 seconds after airplane mode is switched off, depending on local network availability. In some cases it's nearly instant; in remote areas it may take a minute or two. If it doesn't connect within 5 minutes, restart your phone or check that data roaming is enabled.
What smartphones support eSIM?
Most modern devices support eSIM, including iPhone XS and later, Samsung Galaxy S20 through S25 series, Google Pixel 4 and later, Huawei P40 and later, and many recent iPads. Check our full compatibility list before purchasing to confirm your device is supported.
Should I enable data roaming for the eSIM?
Yes - you must enable data roaming for the eSIM line, even though there are no roaming charges. The eSIM connects to a local partner network and your phone treats this as roaming. Enable it: iPhone > Settings > Cellular > eSIMno line > Data Roaming ON; Android > Settings > Network > SIMs > eSIMno > Roaming ON. This setting only affects the eSIM, not your home SIM.
Which eSIM is best for travelling to Mongolia?
eSIMno is an excellent option for travelers heading to Mongolia. We offer a diverse range of eSIM plans - including regional, local, and lifetime options - with reliable coverage on local networks.
What payment methods does eSIMno accept?
eSIMno accepts major credit and debit cards (Visa, Mastercard, American Express), PayPal, Apple Pay, and Google Pay. All transactions are processed through secure encrypted gateways, and we don't store full card details on our servers.
How can I verify if my eSIM is activated?
There are two clear indicators: (1) your phone's status bar shows the local carrier name once you arrive at your destination, and (2) the data icon (4G, LTE, or 5G) appears next to the eSIMno line in your cellular settings. If neither shows up, toggle airplane mode off and on, or restart your phone.
Are there any hidden fees or extra charges?
No. The price you see at checkout is the total price - no activation fees, no hidden taxes, no roaming surcharges. Your data plan is fixed-price, and you'll never receive a surprise bill from your home carrier as long as you keep cellular data off on your home SIM.
Does the eSIM work on cruise ships or airplanes?
eSIMs use ground-based cellular networks, so they don't work in flight or at sea outside coastal coverage. They activate as soon as you connect to a partner network on land. For in-flight or maritime data, you'll need the airline or ship's onboard Wi-Fi.
