GigSky is a data-only service, so your GigSky eSIM does not include a phone number.
You can't use GigSky to make traditional phone calls or send standard SMS messages.
Make calls using apps
You can use your GigSky mobile data to make voice and video calls through apps such as:
WhatsApp
FaceTime
Facebook Messenger
iMessage
Keep using your regular phone number
Your GigSky eSIM does not replace your existing phone number.
If you want to receive regular calls or SMS messages on your usual number while travelling, keep your primary SIM active. Your home carrier may charge roaming fees for calls or SMS.
