Why Am I Receiving Text Messages (SMS) on My eSIM?


When travelling abroad, it's common to receive eSIM text messages (SMS) in different languages, depending on the local network operator. This often includes notifications related to your eSIM, especially in certain Holafly destinations.


For instance, in Asian countries like Taiwan, Singapore, and Hong Kong, operators may send you registration messages to meet local regulations, such as the Real Name Registration from the CMLink provider. Be sure to complete the form to gain access to your internet service!

Can I text with eSIM?

Most of our Holafly eSIMs are data-only eSIMs, so they do not allow sending or receiving text messages (SMS), but there are ways to send and receive messages with international data-only eSIMs.

Alternative Options for Sending SMS with a Data-Only eSIM

  • You can use iMessage on your iPhone since it only requires a Wi-Fi or data connection, making it ideal for data-only eSIMs.
  • If you have Dual SIM, you can text from your personal SIM, just keep your traditional SIM active, but check with your carrier about their charges for sending and receiving messages. 
  • Use internet-based messaging apps If you prefer not to use your regular SIM.
