Short answer: no. 4S eSIM is a data-only travel eSIM. It does not include a phone number, voice calls, or SMS.
What 4S eSIM provides
- Mobile data for supported destinations.
- Internet access for apps, websites, maps, messaging apps, email, and browsing.
- A data connection that can be used by apps such as WhatsApp, iMessage, Telegram, LINE, WeChat, and other internet-based services.
What 4S eSIM does not provide
- A phone number.
- Regular voice calls.
- Regular SMS text messages.
- Carrier voicemail.
Can I still use my main number?
Yes. You can keep your primary SIM turned on for calls or SMS while using 4S eSIM for mobile data. To avoid roaming data charges from your primary carrier, select the label used for your 4S eSIM as mobile data and turn off data roaming for your primary SIM.
If your 4S eSIM line shows No Number, that is normal. 4S eSIM is data-only.
