How does the SMS function work?

To use the SMS feature, you will need two separate subscriptions: one for call minutes and another for data. Once your temporary US phone number is emailed to you, your device will be able to receive text messages. While receiving incoming SMS messages is free, please note the following: - Sending SMS messages is not supported. You will not be able to send outgoing messages using this feature. - It is important to note that we cannot guarantee the delivery of messages from third-party apps or services. You can still try, and while it may work, we cannot guarantee that these messages will actually reach your device.
