Yes, you can disable message encryption, but you must submit a request to our SMSGatewayCenter support team to do so. Once message encryption is disabled, any new messages you send will no longer be encrypted. However, previously encrypted messages from the period when encryption was enabled cannot be automatically converted back to their unencrypted (plain text) form. To access the content of those encrypted messages, you will need to use your unique message encryption secret token to decrypt them.
For guidance on decrypting and encrypting messages, you can refer to our code example here. To request the disabling of message encryption or for assistance with managing encrypted messages, please contact our support team at contact @ smsgatewaycenter.com.
