Apple and the four major US airlines are offering two free months of iCloud's 200-gigabyte level for Some people who want to upgrade their iPhone this fall
The promo listed on Reddit is only available to new (paid) iCloud customers and nominally they should make sure they are "have enough storage space to safely back up all the important things on your iPhone, such as photos, videos, files, and apps, so the data can be recovered as soon as a new phone arrives. The link above mentions Sprint in the URL, but should work for AT & T, T-Mobile, and Verizon as well.
Apple has been offering 30-day trial versions of its paid tiers since May, so the new promotion is actually just an extra month in addition. People signing up will also be charged $ 2.99 per month after the deal expires, unless they cancel.
iCloud only contains 5 gigabytes of data for free, which is sufficient for many people to secure a single device. In the US, Apple Expenses 99 Cents a Month for 50 Gigabytes, 2.99 for 200 Gigabytes, and 9.99 for 2 Terabytes
The company expects to launch three new iPhones at its usual September press event next month. These include 5.8- and 6.5-inch OLED models and a less expensive 6.1-inch LCD device. It's possible that Apple could boost its maximum local storage back to 512 gigabytes, which would make iPhones compete with Samsung Galaxy Note 9.
