Yes, you can usually keep your existing phone number while using an eSIM.
One of the biggest advantages of a travel eSIM is that you can keep your regular SIM active for calls, SMS, and verification codes while using a separate eSIM such as Figabytes for mobile data abroad.
This means you do not have to remove your home SIM, change your WhatsApp number, or give everyone a new number just because you are traveling.
Not necessarily.
An eSIM is a digital version of a SIM card. Whether it comes with a phone number depends on the type of eSIM plan you are using.
Your primary mobile carrier may provide an eSIM that includes:

Before using mobile data abroad, confirm that your home SIM is not selected as your primary data line.

To reduce the risk of unexpected roaming charges:
This setup helps keep your regular number reachable while directing your internet usage through your Figabytes travel eSIM.
Not always.
Many travel eSIM plans are data-only. This means they provide mobile internet rather than a traditional local phone number with calls and SMS.
For many travelers, that is all they need.
Internet-based services can continue working through your Figabytes mobile data connection, including:
Meanwhile, your existing phone number can remain associated with your home SIM.
If having a local phone number, traditional calls, or SMS is important for your trip, always check the specific eSIM plan details before purchasing.
If your home SIM remains enabled and your carrier supports roaming at your destination, calls to your regular number may still reach you.
However, receiving or making traditional calls abroad may result in roaming charges depending on your carrier and plan.
If you prefer internet-based communication, you can use your Figabytes data connection for services such as WhatsApp or FaceTime while keeping your existing number unchanged.
In many cases, yes.
Your existing number can remain associated with iMessage and FaceTime while you use another eSIM for mobile data.

Switching back is simple.
When you return:

Dual SIM and eSIM capabilities depend on several factors:
Many recent iPhone, Samsung Galaxy, Google Pixel, and other smartphones support Dual SIM functionality, but capabilities vary between models and regions.
Always check your exact device model and make sure it is carrier-unlocked before purchasing a travel eSIM.
You normally do not need to transfer your existing phone number to use Figabytes for travel.
Your primary mobile plan and a travel eSIM serve different purposes.
A simple setup is:

For many travelers, the simplest setup is:
You can then use travel data while keeping your familiar number on the same phone.
Using an eSIM does not mean giving up your existing phone number.
With a compatible Dual SIM device, you can keep your home number active for calls, SMS, OTP codes, and messaging accounts while using a Figabytes eSIM for mobile data during your trip.
The key is simple: keep your home line for your number and set Figabytes as your travel data line.
That way, you can stay reachable on the number you already use while enjoying a more convenient way to get connected abroad.
Choose a Figabytes eSIM for your destination, install it before your trip, and use travel data without replacing your existing phone number.
