How Dual SIM works

Dual SIM lets your phone manage two mobile lines. Your primary SIM can keep your number while the travel eSIM handles mobile data abroad.

Why keep your original number active?

Your original number can be useful for bank verification codes, airline or hotel SMS updates, family or work calls, and two-factor authentication.

Reduce roaming risk

After arrival, select Skylano eSIM for mobile data. If you do not want home carrier data charges, turn off data roaming on your primary SIM.

Frequently asked questions

Can I receive SMS while using eSIM data?
