In certain areas of the U.S. some AT&T users found they couldn’t access their inboxes in encrypted email app Tutanota.
Starting on January 25th 2020, we have had constant complaints from AT&T mobile users who were unable to access their encrypted Tutanota mailbox. While AT&T seemed willing to fix this when we reached out to them, the issue is still not solved and reports from users keep coming in.
While some AT&T users confirmed the block, others said that they were able to access Tutanota. As AT&T has not fixed the issue after more than two weeks, we are reaching out publicly in the hope of getting the attention of the right people at AT&T.
