When you send an SMS, the recipient will see your underlying mobile number (the one linked directly to your SIM).
Key Points to Remember
Landline SMS: Landline numbers are for voice calls only; they cannot be used to send or receive text messages.
Receiving Messages: If you want customers or colleagues to text you, you must provide them with your mobile number rather than your landline number.
Caller ID vs. SMS ID: Even if your outgoing voice calls are set to show a landline number, your SMS messages will always show the mobile number.
