Common eSIM questions
Can I use my regular SIM and an eSIM at the same time?
Yes. Most modern phones are dual SIM — you keep your home number active on your physical SIM and use the eSIM for local data.
Can I reuse my eSIM on another trip?
It depends on the plan. Some eSIM plans can be topped up; others are single-use. uPhone clearly labels which is which.
What if I don't use all my data?
Unused data expires with the plan validity. We recommend choosing a size that matches your usage.
Do eSIMs work for calls and texts?
uPhone eSIMs are data-only plans. Use WhatsApp, FaceTime, or any VoIP app for calls and messages.
