International SIM & Network Compatibility
⚠️ For international customers only
Please do not choose a mobile plan that operates through Verizon, AT&T, T-Mobile, or their partner networks, as these carriers are not supported internationally.
Supported Cellular Frequency Bands
Angel Watch™ devices support the following 4G LTE frequency bands:
4G LTE:
B1, B2, B3, B4, B5, B7, B8, B12, B17, B20, B28, B38, B39, B40, B41
(Includes universal/global frequencies)
How to Check Your Carrier’s Compatibility
- Search online for: “What bands does (your carrier) use?”
- Confirm that at least one of the frequency bands listed above is supported by your provider.
If your carrier does not support any of these bands, the Angel Watch™ will not connect properly to the network.
