what do two ticks mean on an sms message

On most messaging apps, two ticks mean the message has been delivered to the recipient’s device, not necessarily read. On WhatsApp, two grey ticks usually mean delivered, and two blue ticks mean read if read receipts are on.

What it means

• One tick: sent.
• Two ticks: delivered.
• Two blue ticks: read, on apps that support read receipts.

SMS vs apps

Plain SMS usually does not show tick marks the way apps like WhatsApp or Google Messages do. If you’re seeing ticks, it’s likely in a messaging app rather than basic SMS.

Common exceptions

• Some apps use different colors or icons for delivered vs read.
• Read receipts can be turned off, so two ticks may still only mean delivered.

In short, two ticks usually mean the message reached the phone, not that the person opened it.
