Installing a Nano SIM card

To install a Nano SIM card:
1. Push the bundled eject pin into the hole on the card slot to
eject the tray out.
2. Insert the Nano SIM card(s) into the card slot(s).
3.
Push the tray to close it.
NOTES:
Both Nano SIM card slots support GSM/GPRS/EDGE,
WCDMA/HSPA+/ DC-HSPA+, FDD-LTE, TD-LTE, and 5G NR Sub-6
& mmWave network bands. Both Nano SIM cards can connect to
VoLTE (4G Calling) service. But only one can connect to 5G NR
Sub-6 & mmWave data service at a time.
Actual network and frequency band usage depends on network deployment
in your area. Contact your telecom carrier if 5G NR Sub-6 & mmWave
support and VoLTE (4G Calling) service are available in your area.
CAUTION!
Do not use sharp tools or solvent on your device to avoid scratches on it.
Use only a standard Nano SIM card on your Smartphone.
