Can my regular SIM stay in the phone while I use the eSIM?

Yes — all compatible phones support dual SIM. Your calls and texts continue to work on your home number via the physical SIM. Data runs through the eSIM at local rates instead of your carrier's roaming charges. Both connections operate at full capacity.
