The Polish site Antyweb reported on 3 November 2026 on an Android flaw dubbed "SMS of death", citing Android Police. One crafted text message is enough to cut a phone off from the mobile network, and the user does not need to click or download anything.
How the attack works
The attack is a "zero click" type. According to the description, the malicious SMS reaches a vulnerable device and crashes the system process com.android.phone. This process handles communication between the modem and the mobile operator's base stations.
The effects are immediate: ongoing calls are dropped, mobile data stops working and the phone loses signal.
The way messages are delivered makes things worse. The phone freezes while processing the SMS, so the operator's exchange never receives confirmation of delivery. It therefore tries again as soon as the device reconnects. After the process restarts, the phone receives the same message and the crash repeats.
Up to a week without service
The person who discovered the flaw says a device can stay in this state for as long as a week. That is how long it takes for the maximum validity period of an undelivered message to expire on the operator's system. According to the description, the only way out is then to boot into Recovery mode and restore factory settings, which wipes the phone.
A fix, but not for everyone
Google has released a patch, but according to Antyweb it covers only devices running Android 14, 15, 16 and 17. Users of phones running versions 12 and 13 have been left out. The author advises installing the autumn security update without delay once the phone's manufacturer makes it available.
What this means for you
The flaw affects Android phones regardless of country, so people using UK and Polish operators may be exposed. It is worth checking which Android version your phone runs and looking for security updates in settings (usually under "Software update"). Release dates for fixes depend on the manufacturer and model. The sources do not say exactly when they will reach specific devices. According to Antyweb, people with Android 12 or 13 cannot expect this fix.
The sources also do not say whether the flaw has been exploited in real attacks.
