No signal iPhone 7 plus

In my case the voice over LTE switch did not make any difference at all. I think maybe that helps on Verizon models, but not AT&T? I have 256g 7 with AT&T. It was replaced once already and the new one is doing the exact same thing, No Service. Went to the Apple store to try and get another swap and they don't have any more in stock to with it. I am just hanging on using my sim in my old iPhone 5 until Apple can release a software update that the Apple Store claims will fix it.

Thank you for the update. What stinks with Verizon is you need to have VoLTE enabled for Wi-Fi calling to work. Hopefully they will be able to fix existing phones with software/firmware update and not a replacement of the phone.

i also have this problem with my iPhone 7 Plus (Verizon). In general weaker Verizon service turns into no service at all, especially while using GPS.

At AppleCare suggestion, I called Verizon to confirm that there were no problems on their end. Spent over an hour confirming various settings with Verizon support, but no solution found. Verizon has forwarded my case to a technical team. I should hear from them by October 4th.

Until a week ago, I was using iPhone 5s on Verizon with solid service in the same area, even while using GPS.

We're having the same problem. Never lost signal with iPhone 6s, but recent upgrade to iPhone 7 causing sporadic "No Signal" even when in a signal rich location. WAZE app causes this to happen even more frequently. A visit to Verizon led to a new SIM, with no improvement. Just spent an hour on the phone with Verizon support - they played with settings but still no improvement. Based on the 7 pages of thread I just read, I'm assuming this is a software glitch with the iPhone 7 and not a hardware issue. Does anyone have any firm data on that, and/or if Apple knows for sure this has been formally reported as a known issue?

Apple certainly knows about the issue (as does Verizon), but it's always a good idea to call Apple Care so they're aware of how many people it's affecting.

The work-around mentioned in this tread worked for me today. The work-around disabling voice in LTE by changing enable LTE from voice and data to data located in settings - cellular - cellular data options- enable LTE. I used my GPS for an hour and a half and I did not experience the dreaded no service. Before changing this setting, I would recieve no service many times during my drive on the iPhone 7. I switched the setting back when I was done using the GPS on the iPhone 7. Hopefully Apple will release a fix for this issue.

Hey ccarrieta171!

This could be a few different things. The iPhone 7 has had a few reports of defective antennas, however there are some troubleshooting steps may resolve the issue if it's not hardware related. Try running through the steps here to see if its software related first: If you can't connect to a cellular network or cellular data - Apple Support

If the above steps don't help resolve the issue but you have an old/spare iPhone available, you can try removing that SIM card and transferring it to the old device. If the old device connects to the cell network, that confirms a hardware on the iPhone 7. See an Authorized Apple Retailer for assistance or possible replacement (this service should be covered by warrantee based on personal experience!).

Note: Below are some advanced user steps. If you are uncomfortable trying them out, visit a Genius Bar for help!

To swap the SIM card, get an object like a paper clip. Holding your iPhone 7, turn it so you are looking at the right side (wake/sleep button facing you). Locate the small circle and push the paperclip with moderate force to remove the SIM card holder. Carefully remove the SIM chip inside. Repeat these steps with the other iPhone and place the SIM chip into the holder, and then the phone. The device should connect without restarting the device.

If you suspect a hardware issue, set up an appointment through the Apple Store or Authorized Apple Service Provider: https://getsupport.apple.com/

Well. please don't underestimate your customers....

there is a hardware and/or software problem. all around the world. why give this tier (0) customer advice.

you pay £780 for a phone that can't use 4G.

Honestly.....

iPhone 7 has the issue. probably os10 has it

apple customer service offer to replace phone. shame they don't have it in stock....

my temporary one plus 3 and old iPhone 6 got signal where my iPhone 7 doesn't

stop advising useless iTunes restoring, network resetting and similar......

This is due to the fact that they forgot to mention in the keynote address from Apple, that they changed to Modem Chip to INTEL. I believe QUALCOMM was the original chipset. Only a certain percentage of the new iPhones have the new INTEL chipset. Hmmm... I wonder how many?

Look it up on google for the full story: "modem chipset in iPhone 7"

VIOLA !

iPhone 7's with the Intel modem are the GSM models. Verizon and Sprint models have the Qualcomm modems. However, this seems to be widespread regardless of the modem as both Intel and Qualcomm phones are affected.

I returned my iPhone 7+ and got a new one...that seems to have solved my issues

The same thing is happening on AT&T. I live in an area of so-so signal. My 5s works fine. My new 7 hardly works at all. It also drops calls in areas of reasonably good service. Have tried everything mentioned, including new SIM card. In desperation have put the new SIM back in my 5s, which is working normally. Must be intrinsic to the phone.

I am having this same issue. My first iPhone 7 was getting a "no SIM card installed" error so I went to Verizon and they replaced the SIM. Told me that if it kept happening, it was probably a SIM reader issue and the phone would need to be replaced. I monitored it really closely over the next week and was constantly getting the "no service" error up to 10x on my commute to and from work, all while using Waze. It is really obvious when you lose signal while using GPS. After a few miles of driving, service would usually come back.

I wanted to replace my phone within the 14-day warranty window so I took it to Verizon and asked it to be replaced.

Got the replacement iPhone 7 within a week and guess what? Still getting the same error. So glad to find this forum to know that I'm not crazy, but I don't know if they would replace my phone again. Hoping there is a software fix I can try because I'm tired of switching phones.

I Had tried a few things to get my 4g back. Up until now only way it would was powering off phone and turning back on.

Tried setting 4g to data only , this would keep it on 4g longer.

As soon as I tried this turning off of automatic carrier my 4g came back instantly.

Will see how it goes and report back if it drops again.

Same problem with my iPhone 5. fixed mine (twice now) by going to Settings, Cellular and turning data roaming off and then on again. Good luck.
