An unknown number of users are reporting that their brand spanking new iPhone 7 is struggling to regain mobile service after Airplane Mode has been cancelled. According to internal documents, the company is aware of and investigating the issue.

Apple’s reportedly advised authorized service providers to instruct customers to restart the affected devices and, if service persists, remove and re-insert the device’s SIM card.

MacRumors reader Yasser El-Haggan posted the following video showing an iPhone 7 unable to regain cellular network access after exiting Airplane Mode alongside an iPhone 6s, which regains two bars of LTE after Airplane Mode is cancelled.

Both devices are apparently AT&T models.

Now, the AT&T iPhone 7 has an Intel modem versus Qualcomm’s in Verizon and Sprint models so this issue may have something to do with the decision to dual-source baseband chips for this year’s iPhone refresh.

El-Haggan took his handset to an Apple Store and they swapped it out with a new one.

“The employee had allegedly seen the issue on a few previous handsets, and he immediately replaced the device per Apple’s instructions in lieu of running a basic diagnostic test,” reads the article.

It’s unclear if this was a one-off replacement or whether Apple’s instructed stores to replace any iPhone 7 units exhibiting the Airplane Mode symptoms, no questions asked.

This isn’t the first issue to hit Apple’s new phone. Two days ago, some owners of new iPhones reported hearing an odd hissing noise coming from the logic board when the CPU is pegged out.

    The AT&T and T-Mobile phones are the same- A1778, A1774 for the 7 and 7 plus respectively (Intel modem and no CDMA).

    Same thing happens occasionally on a 6s on 9.3.3 so probably a software bug showing with the faster CPU.

      I guess the CPUs are so fast that the SIM cards just can’t keep up. *sarcasm*

    I had this happen with my Sprint iPhone 7. I had to reboot for it to recognize the LTE network after it dropped to 3G. And I had 3/5 bars of LTE, which is odd.

    I encountered this problem a few times on my iPhone 6S Plus where it would suddenly enter “No Service” mode and nothing but a reboot would fix it. Nothing new here.

      I too encountered this problem a few times on my iPhone 6S Plus where it would suddenly enter “No Service” . Switching Airplane Mode on/off fixed it. No reboot required.

    Does anyone knows if there is a way to buy a Varizon unit if your device is not with them? I tried online and it’s asking me for varizons service phone number.

      Wait for the unlocked SIM free International version in a month or 2.

      • omakad

        Yeah I wanted to order one asap, but it looks like I’m not gonna be getting it that soon anyway. Mind as well wait for the Sim Free one from Apple.

    I have this issue now on my i7 on o2-UK. No E/3G/4G – takes a lifetime to find a gsm signal. Booked in with Apple tomorrow for them to swap the phone.
