TL;DR

• Google confirmed to Android Authority that the Pixel 10a uses the Exynos Modem 5400.
• This is the same modem seen in the Pixel 10 and Pixel 10 Pro, newer than the Pixel 9a’s modem.
• The new modem enables satellite connectivity on the Pixel 10a.

Connectivity Upgrade

Google has just launched the Pixel 10a, which is essentially the same phone as the Pixel 9a. Both devices use the Tensor G4 processor, but the Pixel 10a features a significant connectivity upgrade.

Google representatives told Android Authority that the Pixel 10a uses the Exynos Modem 5400 instead of the Pixel 9a’s Exynos Modem 5300:

For your question on Pixel 10a’s modem, confirming that Pixel 10a has the same modem as Pixel 10 and 10 Pro: S5400 [Samsung Exynos Modem 5400 – ed].

The Exynos Modem 5400 is a notable upgrade over the older Exynos Modem 5300 seen in the Pixel 9a. The new modem supports non‑terrestrial networks (i.e., satellite connectivity), enabling Satellite SOS functionality for emergency assistance in areas without cellular or Wi‑Fi coverage.

Expected Benefits

Our reviewers did not report major cellular connectivity issues with the Pixel 9a. A more modern modem should improve reception and provide a more efficient overall experience. It will be interesting to see whether the Pixel 10a delivers better battery life on cellular networks compared to the Pixel 9a.

Reader Survey

A March 2025 poll found that about 37 % of surveyed readers considered the old modem a dealbreaker on the Pixel 9a, while roughly 24 % were indifferent. Nearly 40 % said they would wait for reviews and testing before deciding.
