Sms; Contacts - Xiaomi Amazfit Nexo User Manual

SMS

The SMS feature can be used independently through the eSIM card. Whether the
text messages can be received or not is based on the carrier. At present, the SMS
sending function isn't currently supported.

Contacts

If the contact list of the phone call and SMS features is synced from the contacts
of your mobile phone, make sure the Amazfit app is given permission and allowed
to read your contacts.
