If you are receiving the following error:
Please set your device to the correct date. This is a security requirement (and helpful if you forget what day it is).
First, we recommend double checking that your date and time is in fact correct.
Go into your Android Settings>>Date and Time>>Turn on Automatic date and time
Next, check if the security certificate that Textfree needs to connect to the internet is disabled or missing.
Go into your Android Settings app and select Lock screen and security>> Other security settings>> View security certificates>> Turn on Thawte, Inc. Primary Root CA
If Thawte, Inc. Primary Root CA is not an option in your device’s list of security certificates, please reach out to us at firstname.lastname@example.org, and we’ll send you a link to download the certificate to your device.
