Yes! As long as your device supports hotspotting, you can use your Reach Mobile service as a hotspot.
Please note hotspotting on Androids may take up to 24 hours to become accessible.
Are there any limits to hotspotting?
The only limit is the amount of data you have. If you were on the All-In for 20GB, you could perceivably use all 20GB for hotspotting if required.
