Quick verdict: the B311-221’s firmware history shows modest, practical updates (stability, carrier tweaks, security patches) rather than flashy new features. If you rely on stable 4G home internet, updating is usually worthwhile — but proceed carefully: use official sources or your carrier’s image, follow the vendor steps, and back up settings.
