One of the more underrated advantages of using an eSIM in Armenia is that it doesn’t require giving up your home number for the length of your trip — most modern phones let you run both a home SIM and an Armenia eSIM side by side, splitting duties between them however suits you.
Quick answer: Set your Armenia eSIM as the active line for cellular data, while keeping your home SIM active for calls and texts on your usual number — this way you stay reachable to contacts back home without paying international roaming rates for data.

Switching entirely to an Armenian SIM means losing your home number for the length of your trip unless you have a second phone or a physical dual-SIM device — an eSIM alongside your existing physical SIM avoids this trade-off entirely, letting you keep your usual number reachable while getting affordable local data, covered further in the local SIM vs eSIM guide.
Setting this up on iPhone
Under Settings, Cellular, iPhones let you assign separate roles to each line — designate your home SIM for calls and texts, and your Armenia eSIM for cellular data specifically. The Armenia eSIM iPhone guide covers the general installation process this builds on.
Setting this up on Android
Android’s approach varies slightly by manufacturer but follows the same general logic — assign your Armenia eSIM as the default for mobile data under your network settings, while leaving your physical SIM handling calls and texts. The Armenia eSIM Android guide covers manufacturer-specific menu differences.
Avoiding accidental roaming charges
The most common mistake with a dual SIM setup is forgetting to disable data roaming on your home SIM, which can result in your phone quietly using expensive home-network data instead of the much cheaper Armenia eSIM — double-checking that data roaming is off for your home line, while your Armenia eSIM handles data, avoids this. The roaming charges guide covers this risk in more depth.
Hotspotting from a dual SIM setup
If you also want to hotspot a laptop or second device, most phones let you share data from whichever line is designated for data — the hotspot guide covers this specifically, useful for travelers combining dual SIM with the need to connect an additional device.
Receiving SMS codes on either line
Some services send verification codes to whichever number you originally registered with, so keep in mind which line — home or Armenia eSIM — you’ll need active to receive specific messages, particularly if you’re setting up a local ride-hailing or delivery app that might expect an Armenian number. The eSIM not working guide covers what to check if messages aren’t coming through as expected on either line.
