Phone Reboots Randomly While Traveling/Strange Text

I’ve been using my Brax3 phone solely for 1) calling/texting via PSTN and 2) as a mobile hotspot for a separate de-googled phone (for internet use) while traveling.

I’ve been having a strange reoccurring issue where the Brax3 phone will randomly reboot itself without warning; each time it does, a text pops up with the exact same message which seems to be some kind of coding that I can only somewhat figure out. Something with “len=”, “smtp_u=”, “smtp_pw=” and a bunch of numbers and letters. I do recognize my phone number and voicemail password within the text, which is why I’m not copy/pasting it in here.

Anyone else having this issue? The text sender number is always the same as well, ‘1000000000’, which within this context makes me think it’s some kind of interaction between the phone and cell towers. I’m not a tech guy so I don’t really know what’s going on with this, but it just seems like some kind of technical bug I’ve been having since I first got the phone. Updates haven’t seemed to remedy it.

I’m unsure if the phone has rebooted every time that text pops up but the hotspot had turned off every time I’ve seen that text, so I’m assuming it’s also rebooting and I’m just not noticing that it’s rebooting.

Update: Koldunya pointed out in another thread that this seems to be related to the ATT network. I’m still not sure why the phone reboots on its own though.

Welcome to our community!

I found more context about the message you’re receiving: Reddit - The heart of the internet

It is supposed to be a silent SMS sent to your phone (telcos send quite a few of those for different configs), but sometimes it is showing as it seems with AT&T. It doesn’t seem to be related to any error.

If you block the number, which doesn’t seem to affect the service, you should stop receiving those notifications.

Having said that, it doesn’t seem that the notification you see is related to the device rebooting.

Let’s try to narrow this a bit:

  • Have you noticed any pattern with the reboot? Like any activity before the device reboots?
  • How often would the device reboot?
  • Can you confirm which OS version are you currently using?
