I recently switched to at&t, my phone says 4G but not LTE, is there something wrong? My iPhone was bought at best buy and used with tmobile first then got it unlocked if that makes a difference.
After more than 15 years covering everything Apple, it’s with a heavy heart we announce that we will no longer be publishing new content on iMore and the iMore forums will be closing as of November 1st, 2024.
And, to truly confirm, I would restart the device, to reconfirm that it is still active, and not just a fluke.
