Dialing and Mobile Codes

Respect Time Zones: Send messages during the recipient's local daytime hours unless urgent.
Support HELP/STOP Commands: Ensure SMS campaigns support these commands in the local language for subscription management.
Do-Not-Call Registries: Avoid messaging users on do-not-call or do-not-disturb lists.
