iPhone problem is fixable, but time consuming

Over the last few weeks, iPhone users around the world have started to see an infuriating bug appear. Seemingly at random, iMessage and FaceTime deactivate, and can’t be re-enabled.

The high-profile victim that has brought the bug to wider attention is none other than Bloomberg’s Mark Gurman, who tweeted about his experience. This exposed exactly how widespread the bug has become, with users everywhere from Italy to the Philippines impacted.

The problem seems to only impact those who use their iPhone’s eSIM chip, rather than a physical SIM card. Gurman claims that the bug impacts at least three versions of iOS: 15.4, 15.6 and 15.6 beta 1. “Potentially earlier too, but that’s all I can confirm right now.”

There seem to be two solutions — what you’d loosely call an easy way and a hard way. The easy way, and the one that Gurman opted for, is to switch to a new physical SIM card. The harder way is to remove the eSIM account and set it up again from scratch. 

“That’s complex for most people and shouldn’t need to ever to [sic.] be done,” Gurman tweeted. “Not being able to send and receive texts is obviously not ideal. Not ‘it just works.’”

In the U.S., there have been reports of T-Mobile and Verizon users impacted, but nobody wants to claim responsibility. As one commenter on 9to5Mac reported, Apple blames T-Mobile, while T-Mobile states it’s an Apple issue. 

“The really frustrating thing was the finger pointing between Apple and T-Mobile - with neither really helping resolve the issue,” the poster lamented, after finally getting the latter to provide a physical SIM.

A warning for future iPhones

With most of the world still to make the move to eSIM, and a simple (if slightly time-consuming) solution available, this may not seem like too big a deal. But it provides a warning shot to Apple’s rumored direction of travel which shouldn’t be ignored.

Whether it’s in 2022, 2023 or later, an eSIM-only iPhone is “a question of ‘when’ not ‘if’” according to one analyst. If this bug had struck at such a time, then the ‘easy’ solution of popping in a regular SIM card simply wouldn’t be possible. Nor would you be able to move your SIM card to another temporary handset while Apple resolves any other problems preventing communication.

Of course, in this hypothetical scenario where iPhone SIM cards no longer exist, the problem would be much more widespread, and thus probably quickly resolved. All the same, it’s a timely warning that ‘simplifying’ phone design can sometimes make things more complicated in unexpected ways.
