Can I be opted out of ever automatically adding these trial services that I’m then responsible to cancel or I’ll get charged in the future please
As far as other trial in Verizon I can not say. The Verizon Cloud trial either initiates as part of the device provisioning where setting up the Verizon Cloud is an optional part, so the trial was selected, or a plan change that contained the trial as a part. Users get an SMS with a cancel link at the start of the trial, after the first few days, half way through, and before the end that contains a link to cancel the trial. While yes this requires an 'Opt Out', there's 30 days of time to make that tap on the link offered.
