If you’re not receiving One-Time Password (OTP) messages on your Android device, they may be going to your Spam or Blocked messages folder. Android automatically filters messages it thinks might be spam. Follow the steps below to ensure you receive OTPs without issues.
Step 1: Check Your Spam Messages
Open the Messages app (Google Messages or your default SMS app)
Tap the three-dot menu (⋮) in the top-right corner
Select Spam & blocked
If you see an OTP message from Spacetalk:
Open it
Tap Not spam
This helps Android recognise future OTPs from us as safe.
Step 2. Add the Sender to Your Contacts
Saving the sender number makes Android less likely to block future messages.
Open the OTP message
Tap the sender number
Select Add to contacts
Step 3. Ensure the Messages App Has Required Permissions
Go to Settings → Apps → Messages
Tap Permissions
Make sure SMS is allowed
Set it as your default SMS app
Request a new OTP
