TL;DR
For eSIM, enable roaming via your carrier's app or by sending an SMS to your provider. A physical SIM card works without extra setup — messages arrive automatically.

Roaming for eSIM is activated through your carrier's personal account or app. You typically need to send an SMS to your provider's support number — check the exact command with your carrier before traveling.

If your eSIM in Nha Trang only gives access to a limited set of apps (e.g. TikTok or ChatGPT work but others don't), roaming is likely not enabled. Activating roaming restores full internet access.

A standard physical SIM card requires no extra roaming configuration in Nha Trang — just leave it in your phone and SMS messages will arrive normally.
