# ZERO eSIM vs TDAC Arrival Card Assistant

The clearest difference is rating: ZERO eSIM at 4.8 against TDAC Arrival Card Assistant's 4.3. ZERO eSIM also leads on ratings volume (137 vs 11) and device support (4 vs 1). TDAC Arrival Card Assistant's advantage is in-app purchases (none vs 4) and update cadence (every 2 days vs every 10 days). On price and ads there is nothing between them.

Both are free to download. ZERO eSIM sells 4 in-app purchases, starting at $2.99 per 7 days. TDAC Arrival Card Assistant asks for nothing beyond the download.

ZERO eSIM holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: ZERO eSIM has 137 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 58% of ZERO eSIM's written reviews are positive against 67% of TDAC Arrival Card Assistant's, so the app with the better star average is not the one people write more warmly about.

ZERO eSIM ships an update every 10 days, TDAC Arrival Card Assistant every 2 days. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
