iPhone 5 - Difficulty Capturing Network After No Signal

Can you replicate the wait time by switching the phone into airplane mode for 30 sec then switching it off, or similar wait times when you boot your phone?

If this network wait time is persistant in all these situations at different locations, then I think I would recommend a factory restore, and if that does not fix it then a trip to the apple store.

However, I think it might be a low or weak signal at your work place? I don't have any trouble with my iphone 5 picking a signal back up within 10 seconds, and I regularly go into "no service" when I am in my apartment.

 

I have just always had this issue, both on the 4s and my current 5. At work, data signal is pretty spotty. At the end of the day, when I leave the building, I see 4G, but absolutely cannot get any data. What I usually do is airplane mode on/off and it seems to work majority of the time.

Not sure why this happens. Seems like something Apple can patch with an update.

 

Try a reset network settings.

 

Yeah, my 5 is doing this (on 6.0.1) and it's not just an annoyance - I've missed calls due to my having driven through a 2-minute stretch of bad signal AN HOUR AGO and my phone still won't receive calls, texts, or push data unless I first *place* a call outbound. At that point, everything connects back up again! Unacceptable. I shouldn't have to babysit my phone's connection by placing "wake up calls" through it.

Oh, also: putting it in airplane mode and back out again fixes it. It's a hack.

I called Apple and they acted like they'd never heard of this and told me to "Reset all settings" (not just network!). I'm not doing that. I think 6.0.1 probably needs a patch or something.

 

I'm having the same exact problem, turning wifi off, airplane mode on and off, and network reset has not helped the problem. My phone was ordered on the first day so i wonder if there are issues with the early iPhone 5's

 

Update:

I installed iOS 6.0.2 and no signs of improvements
