Visible is kicking off a new promotion to entice Apple Watch users to switch over to its service. If you haven’t been swayed by any of the existing iPhone 15 promotions since the new smartphones launched last week, the Verizon subsidiary is now debuting a new offer that just might. Right now when you activate an iPhone on Visible Wireless, you’ll be able to add a new or existing Apple Watch to your plan at no extra cost. Applying code WATCHPROMO at checkout cuts the usual $5 per month fee off your bill for the first year, saving you $60 off your first 12 months of service. More details below the fold.
