Can I use my EastESIM for internet while my digital Suica/Pasmo card is on the same phone?

Yes, absolutely! Your EastESIM, providing seamless internet connectivity across Japan, operates independently from your digital transit cards like Suica, Pasmo, or ICOCA. Both services reside on your iPhone or Android device without interference. You can confidently use your EastESIM for navigation and communication while still tapping your phone at ticket gates or for payments at convenience stores. They are complementary services designed to make your Japanese journey smooth and efficient.
