Frequently Asked Questions — United States eSIM
What is the best eSIM for visiting the USA?▾
Giga.tel offers several USA eSIM plans covering major US carriers. For most tourists, a 10 GB or 20 GB plan is enough for a one- or two-week trip, with options for unlimited daily data if you stream heavily.
Will an eSIM work on my phone in the USA?▾
Yes, if your phone supports eSIM (most iPhones XS/XR and newer, and many Android phones from 2019 onward). You can verify in your phone Settings > About > available eSIM.
Can I keep my home number while using a USA eSIM?▾
Yes. Set the USA eSIM as your data line while your physical SIM keeps your home number for calls and messages. Most dual-SIM phones support this natively.
Do I need to unlock my phone to use a USA eSIM?▾
Your phone must be carrier-unlocked to install a foreign eSIM. Phones bought directly from Apple or Google are usually unlocked by default.
