Can I Send Texts with a Mossroam eSIM?

Most Mossroam eSIMs are designed for data-only use, meaning they do not support sending or receiving traditional text messages (SMS). However, there are alternative methods to send and receive messages using a data-only eSIM.

Alternative Options for Messaging with a Data-Only eSIM

  • iMessage on iPhone: Utilize iMessage, which functions over Wi-Fi or data, making it perfect for data-only eSIMs.
  • Dual SIM Setup: If your device supports Dual SIM, you can send texts via your personal SIM. Keep your physical SIM active, but verify with your carrier about potential charges for messaging.
  • Messaging Apps: Opt for internet-based apps like WhatsApp or Telegram if you prefer not to rely on your regular SIM.
