I have an iPhone 6s that has the searching/no service issue. I’ve seen this a lot online with the iPhone 6/6 Plus, but no one really talks about it with the 6s. Is it caused by the same baseband ic issue or is it another chip? I’ve looked around to get this repaired, but no one really seems to offer this service. Does anyone know where I can get this chip reballed? Thanks in advanced!
Give a shout out to @refectio here on IFIXIT, or search through the pros here on iFixit. If you cannot find what you are looking for here, search for Chris Long on youtube. I’ve done several 6 and 6 plus, but not had the “6s or 6S+” with searching or no service.
The antenna may have become dislodged. While sitting down, turn your phone screen facing down in a horizontal position across your upper leg.Firmly rock it left-to-right across your upper leg for about 5-10 secs. (Be careful not to do it so hard that you bend your phone).Switch your phone to Flight Mode and back again to reinitialise the network search.Repeat if necessary. This should re-seat the antenna and restore network connectivity. I had exhausted all other software options, and this is the only thing that actually worked for me! I’ve been doing this for a few weeks now and it consistently restores service to my iPhone 6. I still lose network every few days (sometimes multiple times in a single day), but this method restores it every time.
This is pretty common for every 1/10 Iphones. I always review the following. Check for Carrier Updates, this is typically done with the sim and wi-fi connected. Check for iOS UpdateTest for Signal, if fail proceed to next steps.Look for APN settings on the phone and remove it, this can cause a signal interruption. I believe it’s in Settings>General> APN. This does not appear in all phones and this varies on where the phone was purchased from. Some APNs can be found in Cellular > Cellular Data Options > APN/Cellular Data Network. Just look around to see if one exists. Test for Signal, if fail proceed to next steps. Manually search for a Network in Settings > Carrier (turn off automatic) see if you can manually search for the tower of your carrier.Test another Sim Card to ensure it’s not a hardware issue. Frankly, some phones, primarily samsung, gets picky about the sim type you use. I’m not familiar with Sim Cards and how they function, I just know that if one type doesn’t work try another type. Hope this helps.
Have you opened it recently? If so, a antenna connector cable could have came lose or not been fully seated back .
Hi all, i have the same problem. My sim card is being detected but I have no service. The sim is working in another phone and the iPhone is water damaged,so I’m pretty sure it’s a hardware problem. Do someone know which chip it is most likely? Or which chips are involved in this issue?
I have same issue. Probably software issue. Need downgrade or something upgrade to solve. My phone have iOS 11 update of 1.21gb size but I am not updating hoping my iPhone will die or any other issue will arise.
Then d baseband (network) ic should be replaced or reballed. Few Engineers do it in Lagos Nigeria
yes this issue must be fixed by apple ,or file a suit
I have the same problem. my phone works perfectly on T Mobile, it’s the model a1687 so it should have worked with Verizon but it doesn’t. when you turn on the phone or after switching airplane mode on and off its says “searching” then it shows “Verizon” for a few seconds with no bars and then “no service till the end of times” After doing some research I found out the problem, and it’s that Apple sucks in every conceivable way
Just putting it here because I had an 6s with the same issue and found that the culprit was the aerial jumper linkage in the top left of the phone, doesn’t look faulty but there was a definite resolution of the signal issue when it was replaced. It was initially very dirty so I cleaned it the first time but didn’t help. So if all else is failing then this might be just the answer you are looking for.
if no service or searching need to reball baseband or bbpmu (power managment for baseband)if its freeze sim no sim after few secconts replace u5411 ic and problem solvet…all time this problem happen after lcd replacement
Same problem here. Just wondering how on earth it could possibly happen? Worked fine from the start, and just stopped and now screaming “No service” all at once… Replacing the SIM, resetting “Network settings”, resetting ALL settings, and no luck!
I also face the same issue with my iPhone 6s. Having a doubt. When some people fix the screen protection sheet, they press the screen heavily. Will this lead to this kind of problem?
Hello. See this video for fix Searching/No Service iPhone 6 on youtube : https://youtu.be/6rx_TOfgHqg
Dec 2018 same symptoms here. Above loose connector fix did not fix it. I also noted that when syncing to pc (itunes) that it always insisted applying a network patch. Just before opening my i6 l tripped across apples site saying to follow a procedure at their site to fix. Support.apple.com/en-za/HT201415 or search no service or searching Both iphone and ipad my i6 is only 6 months old and lost my receipt so l am so glad this worked! charles
I had this issue on a phone I was working on yesterday. I performed various tests including a new charge port with a new antenna with no success. It was a locked device so I couldn’t test it with a new sim card. It just suddenly began working again after trying for 45 minutes. Our master technician said it could have been a bad IC chip, which reballing wouldn’t have solved and it can’t be replaced. He also said that iPhone 6s, 6s plus, 7, and 7 plus have been known to have this issue every once in a while.
I recently got my screen replaced. Prior to that thou, ive never had this problem im thinking when he replaced my screen he might have accidently did something . when i shake it it does sound like something is loose. How do i open the screen? i dont wanna mess up my Ihpone6Plus. I really love this phone
May be I can help you with this …
i have same problem iphone 6 Solution plz…
I’ll suggest two things to try. Do the first one and test for results. If no good then do the second one. remove the SIM card and clean the contacts with a pencil eraser.Follow the guide on iFixit for replacing the antennas. I did this recently on my wife’s iPhone 6 which was having cell connection problems. It was constantly dropping calls and the phone would indicate poor signal or no service. The GPS functions were also not working well. I replaced the antennas but might not have needed to. When I was disassembling the phone I found many of the screws holding in the antenna were loose. Making sure those connections are clean and tight could be the only fix you need. In my case I went ahead and replaced the antennas since I had new ones right there. The problem is solved in our case.
