Force iPhone to Find Network
I live in New York, so I’m constantly losing my iPhone signal when I go onto the subway. Sometimes when I get off the train and I’m back in range of the phone still can’t find the network. Recently, my phone has randomly also been telling me “No Sim” even though it’s just been sitting on my coffee table or desk (and been in range).
To get my signal back I used to turn the phone completely off, and boot her back up. This solution was alright, but it took a lot of time and it occasionally took several attempts for my phone to actually find the network. So, I have new method. I simply:
- Go to Settings
- Turn Airplane Mode on
- Wait a few seconds, turn Airplane Mode off
Turning Airplane mode on disables the wireless features of the iPhone, and then turning it back makes the phone re-register on the network. I’ve had better success getting my signal back by toggling Airplane mode rather than rebooting the phone. Good luck!

#1 Peter says:I’ve noticed the same problem, and my last Blackberry was much better at coming back to life (nudge nudge apple, don’t let BB win!)
Also to note, if I attempt to make a call and there’s no signal, it should immediately go looking for a signal, instead of waiting till the next interval time. I’m guessing the interval is pretty large for battery reasons. Valid, but let me force it to check if I do something that needs radio. This includes sending TXT messages, as the iPhone has no ability to queue them up and send when the radio becomes active.
p.s. Not being able to write/queue up texts when I’m on the subway is one of the biggest negatives I’ve had for the iPhone, and one that’s easy to fix..
#2 Mike Germano says:As a New Yorker I always have that problem wish I thought of this earlier. Great tip I will use it in a couple hours on my commute home.
#3 kortina says:Didn’t ever think of that. Makes sense. I ride the subway with Germano, so I’ll be using this tip a lot too.
#4 Honza says:The ‘no sim’ thing… I think either your sim or iPhone is faulty. Assuming you are using the ATT sim, otherwise you may have a slightly incompatible sim card. Shouldn’t be an issue these days, but I have seen this in the past.
