Fix Signal Dropping / No Service Problem in iPhone After iOS 8 Update

Last updated: September 25, 2014 at 2:36 am
No service bug on Apple iPhone

Update: If your carrier is searching for signal or showing “no service” message, follow this guide. These solutions works even with iOS 8.0.1 update.

Is it true that an Apple iPhone with iOS 8 keeps losing the carrier network signal frequently? And does it show a “No Service” signal message at the top-left corner of your screen… meaning you cannot make phone calls anymore? In this article we will share our thoughts on the iPhone’s poor signal strength and three simple solutions to fix this problem.

No Service And No Cell Coverage Issues Explained

After installing iOS 8 firmware on an iPhone 4s, we quickly decided to try out the new features, not remembering to check the signal strength. So next time, we updated iPhone 5s to iOS 8 and saw the “No Service” message at the top-left corner of the iPhone screen.

Solution? Before we could do anything, the problem fixed itself. Yes, magics do happen in the iOS land. So here’s a tip: if you are facing a “No Service” message right after installing a new firmware, just wait.

You may get a “Searching…” or “No Service” message, but if you wait for another 10-15 seconds, the message will disappear and you will get some signal strength back.

Of course, the above solution requires “pure luck” right? We don’t know why the signal drops on iOS 8, but we always believed it was because of our location where the network coverage is usually very poor. So whenever we receive calls, all of us in our family have to walk around the house to get minimum signal strength on our iPhone.

But how about a few “working” solutions? We have them for you and we are very sure these fixes will stop the signal dropping issues permanently on your Apple iPhone. Here we go:

How To Fix Poor Signal Strength Problem Permanently

We have three solutions to get a good cell coverage service on iPhone:

  • Use Reset All Setting
  • Disable Data Roaming
  • Pick carrier manually

Sure, you can do a full restore or clean install iOS 8 on your device. Those are extreme methods we do not recommend right now. The first step is to try the above methods that will help you get rid of the “No Service” error message, stop signal losses and bring back the reception dots. Let’s explain how to execute each of these solutions:

Fix 1: Use Reset All Settings

How it works: From your Apple iPhone, go to the following: Settings -> General -> Reset -> Reset All Settings. Before you click on the “Reset All Settings” you should know what it does.

Reset All Settings will reset your device’s settings without erasing data. Does it delete photos, contacts, messages? No! What it really does is wipe out network configuration, passwords of WiFi network and minor changes.

Remember: If tapping one time doesn’t bring back the signal, try it again. Tap “Reset All Settings” few times and the signal bar will eventually show up. Also note that after you have executed this process, you have to  manually enter password to connect to your WiFi network.

Fix 2: Disable Data Roaming

How it works: If you have activated or turned ON roaming option, then disable it and see if it solves the signal issues. Disable data roaming by going to the following: Settings -> Cellular -> Data Roaming.

When iOS 8 beta users faced similar signal problems on their iPhones, disabling this option did the trick.

Fix 3: Pick Carrier Manually

How it works: Should you blame iOS 8 for frequent signal losses? We can’t be absolutely sure, but picking the right carrier solves the problem. Here’s what you should do: Go to Settings -> Carrier -> Disable Automatic selection and look for the network carrier manually.

Apple iPhone will now search for the right carrier and show you a list (if any) of network carriers you have to choose. That’s it!

Let us know if you have any similar problems related to signal strength, how you tackled it, and which method did you use. We hope this article has helped your iPhone get back signal strength it deserves.

Note: We tried to replicate the problem and see if hard reset would fix it. And it did not. So don’t try to hard reset your iPhone. Simply resetting all settings solved the problem immediately. Even taking the GSM SIM card out and inserting it back again proved helpful.

  • numan

    yes im facing tha same problem
    so much irritated
    no service 2,3 times in an hour

    • kamal

      Did you find any alternative of your weak signal ?

  • yehlie

    same here… sigh…. grrrr

  • Horace S. Patoot

    At least in our case I don’t think it has anything to do with signal strength. We have two iPhones and two iPads that consistently show three or four bars (dots) or more, except that one of them goes into NO SERVICE mode and after a period of time or a restart goes back to three or more bars. This happens very frequently but never happened once before the upgrade. It’s not a problem since we have wifi; just an observation.

  • Anthony

    My phone has been searching for signal since I updated a few days ago (4s). I did the network reset. I took the sim out and it’s not saying sim not installed. I restored from iCloud back up, nothing seems to work. Is this a downgrade? I need help.

  • Anthony M.

    WOW. After my daughters upgrade she has not been happy. We tried fix 1 and everything was working perfectly.

    I just wanted to say thank you for the help !

  • Jacqueline Samuel

    THANK YOU!!!! Fix #1 worked for me! Last Friday, I updated to iOS8 on my iPhone 4S until I could get the i6+ and have had no cell service and intermittent text and internet abilities since!

  • KNH

    I have been having problems for two weeks now and nothing seems to work – even after calling my network provider and Apple.
    Seems that they want you to download the ios 8 and then no one wants to help after this

  • paula

    Tried the above. Didn’t fix my issue.

  • Arjun

    Yup, had a similar issue the past few days. I’m from India and bought the unlocked one from the US, this issue seems to occur often though. Weird :/ However, a quick toggle and it works out fine. Sometimes even the toggle doesn’t seem to make it work well though. Praying they release an update soon!

  • Lee

    Hello Im also experiencing searching signal network in my iphone 4s after updated to iSO 8, its been 3 days already but still my iphone still searching for network signal. I’ve already tried all what you have said but it’s not working. Is there anyone know how to fix this problem?

  • Shreyash

    i have iPhone 4S. I have try all above possible solution. but nothing seems to be helpful for me. Still i have searching.. and No Service problem. Please let me know if there is any other solution to resolved it. Thanks.

    • kamal

      i have same issue. what is the best alternative ?

  • sachin

    I have iPhone 5S. recently my carrier company AIRTEL has provided my 4G SIM and since then facing problem. I have try all above possible solution. but nothing seems to be helpful for me. Still i have searching.. and No Service problem. Please let me know if there is any other solution to resolved it. Thanks.

  • Jack

    I’ve just tried all of them and I’m still getting the same thing now and then

  • Joe

    I often find I lose signal in 4g areas. If ‘no signal’ pops up I disable the 4g settings and reset my phone. When it starts up I’ve got 3G and don’t lose signal. Worth a shot if the above doesn’t work

  • kamal

    which option ?

  • Prissy

    Same issue for about 2 months. Can’t constantly reset the settings and taking SIM out. I have had enough and finally got it replaced. Hopefully the replacement phone will not call for the workarounds.

  • Pablo Caceres

    I have the same problem after upgrading ios 8.1.2 lost all signs . probe all solutions that give you and nothing happens. restore from itunes and just finished the restoration has to set the signal but loses all signal iphone again. I need help please !!!!!

  • Sendu

    No one of this share working, why you dont fix the problem for the iphone users?signal and wifi are too weak after ios 8.1.3 release… Fix it if you care…

  • Pat

    I have been having this same issue for a while now and as soon as I can I’m going to get a different phone, probably an HTC. This experience has been the worst that I have ever had with any phone.

  • Ankit deswal

    I m also facing the same problem in a day 18/24 hrs my phone shows no service . The best way to get the network i found is to reinsert your sim card. I reinserted my sim card 13 times in a day this is worst ever thing i saw in iphone . They released 8.3 version but the problem is not yet fixed

  • Bhawanshu

    yeah reset setting my iphone 5 was very usefull, as my airtle sin 4g was not showing signals. NO SERVICE at the top left corner. Thanx for the HELP :)

  • Doreen

    yes the reset settings worked after 3 times on my iPhone 5s. It happened before and if was like that for about a year! then I updated to IOS 8.3 and it was fixed for about a month. My phone is on airplane mode 90% of the time and a few hours ago I turned it off and saw the “searching…” thing again and it was the worst feeling ever to think that I wouldn’t have signal until another IOS update. But then I tried this and it actually works for now. hope it’ll last :) tnx alot

  • Manu

    Thanks Man, Reset all settings works gr8, fed up of the NO SIGNAL issue thanks for the help :)

  • Jamie

    make sure before resetting all settings that you know where to locate your backgrounds and know all of the settings you are used to because you will have to reset them again

  • Luca

    many thanks for the article, after 2 days no signal on my iPhone6, lots of frustration, an unhelpful visit to the apple store today, finally it has worked for me with your Fix 3: Pick Carrier Manually, have select Virgin that is my SIM provider and all good!

    • Haute Culture Books

      yes it worked for me that way too

  • Nick

    It’s 2015 and Apple is not able to make a phone that always connect to the network? A few times a week a must switch to aiplane modus and back, to force my Iphone 5s to reconnect the provider. Next buy will be Samsung
    Most annoying is that you don’t know how long you were unreachable.

  • Pavan Angirekula

    i too got the same problem but its different when my data pack is vanish( inactive) i phone shows “NO Service”. i need to again recharge with a 3G data pack then i can see my signal popping up dint know whats wrong with it . . . can any one helps me in fixing it

    • Saurav Chintapatra

      you must be using Vodafone IN which assigns different n/w capability for different data type (2G/GPRS, 3G, LTE). So, once your 3G data pack is over, the network goes to 2G mode which the iPhone is not able to connect to. So Head to Settings>Mobile Data>Voice & Data>Change according to your situation.

      • Miles Grady

        I have same issue and am with Vodafone. If I turn on my phone at home it sticks on searching (not no service) and will stay like that if I drive around various places. If however I’m in a town centre (with presumably a superior Vodafone coverage) and turn my phone off and on it will connect. If I go home I stay connected unless my phone goes off and then the next time I turn it on it again won’t connect. Ie once connected it stays connected. It’s like my iPhone is getting a signal back on trying to connect saying my number is blocked. Same happens if I put sim in another iPhone.

        I’ve raised with Vodafone saying it appears to be the sign up routine at some locations doesn’t work. All happened after latest Apple update.

  • Matthew Carter

    Here’s irony. In the UK Apple are advertising how they write their software for their hardware. Great! So why doesn’t it work?
    None of the above fixes have worked on my iPhone 4s, and no way to revert to an OS that works.
