Yes, on a dual-SIM phone you can keep your usual line active and use the travel eSIM for mobile data. To avoid unexpected charges, check your home provider's rates for calls and texts, and turn off data switching to your home SIM.
A data-only plan gives you internet access but not a number for standard mobile calls or SMS. You can still use internet-based calling and messaging apps. Any calls or texts on your usual line will be charged by your home provider.
Check the options for your eSIM in your Cellesim account or app. If a top-up is available, review how much data it includes, how long it lasts, and how to activate it before you buy. Otherwise, you may need to buy a new plan.
Your connection depends on the networks in your plan, your phone, and local conditions. Check the plan's network details, as service can be affected by buildings, remote locations, and network traffic.

This depends on the plan, so check its activation details before you set it up. Buying a plan, installing it, and starting it are not always the same step.
Make sure the eSIM is turned on and selected for mobile data, then follow the setup instructions from your order. If it's still not working, keep the eSIM installed and contact support with your order details. Please don't delete the eSIM to try and fix the problem.
Check the requirements for your chosen plan before you buy. Some destinations and providers may require you to verify your identity.
No, you can keep using your existing WhatsApp number with the eSIM for internet. You don't need to change your number.
Check if your plan allows hotspot sharing and if your phone supports it. If so, you can turn on your phone's personal hotspot, and other devices can share your data.
Please contact support if your eSIM doesn't work. Whether you can get a refund depends on our refund policy and your plan's status, such as if it's been activated or used. Check the policy before you buy.
Look up your phone's exact model number and where you bought it on our compatibility page. You can also check if your phone has an EID number or an “Add eSIM” option, but be sure to also check for any regional or carrier restrictions.
Read the list of covered countries on the plan's page. A single-country plan and a regional plan can cover different places, so don't assume a nearby country is included.
