The correct answer is B. Slow data speeds C. No wireless connectivity. A '1x' signal indicator means the phone has fallen back to a 1G/CDMA data network - the oldest and slowest mobile data standard. This directly causes two symptoms: slow data speeds (B), because 1x is far slower than 3G/4G/LTE, and no wireless (cellular data) connectivity (C)…

Explanation

A '1x' signal indicator means the phone has fallen back to a 1G/CDMA data network - the oldest and slowest mobile data standard. This directly causes two symptoms: slow data speeds (B), because 1x is far slower than 3G/4G/LTE, and no wireless (cellular data) connectivity (C) for practical purposes, since many modern apps and services cannot function on 1x. An iOS update can sometimes corrupt or reset the baseband/carrier settings, causing the modem to register on an incorrect or degraded network band. Slow performance (A), application hangs (E), and overheating (F) are unrelated to a network downgrade, and baseband (D) is the root cause component, not a symptom.
