iPhone searching signal constantly

Had this problem for three days. New sim. ATT reset my phone on the network. Nothing. Reset phone to factory default. Works for a hour or two. Last time it happened I smacked my phone on the table and immediately started working again. Will test this method again once it stops working again.

"Was having this issues for months. Searching hours on google to find an answer. I replaced the Lightning Charging Assembly which included a cellular antenna, cleaned all the grounding points in the case, and replaced the antenna flex ribbon. None of this worked.

1) Software wasn't the issue. DFU restored, everything, it still continued.

2)Cellular settings being changed had no effect on the signal.

3) Hardware was the obvious in this case because ""smacking"" the phone caused it to regain signal.

A few days later I noticed my phone said ""NO SIM"" and started to think. This is what the problem is. The sim slot in the iPhone 6 can get deformed by slight bending in the phone. This provides the SIM card with a hairlike gap to wiggle around in. The simple fix for this is to take a sheet of printer paper and cut it the exact size of your nano-SIM card and place it on the plastic side of your SIM card which faces up and then insert it. Do this carefully and make sure the paper doesn't crinkle/fold in half. This tightens the SIM card very slightly but just enough to keep it tight to the gold connectors.

My phone was loosing signal, and saying ""Searching"" for weeks, and after this it is working 100%!

Three days and strong signal ever since.

Goodluck!"

"Good day everyone! Manchester UK and !&&* YEAH it worked!!! Same problem here, mo carrier services, device constantly displaying searching mode out if the blue - I spent an hr on the phone with Apple without a resolution then they sent me to their store which was busy and on a conveyor belt and the guy opened my sim card locket, pretended he looked inside with an expert eye and said i have water damage! I said to him how is it possible that my phone works on all other functions and wi fi etc - he said the phone cannot be repaired and since it's out of warranty i could get a new one for £200. I said i need to think about it, left there upset and feeling conned!

So i found all these wonderful wacky ""bash it"" experiences - and said to myself well, if i smash it it's my own fault and the phone is ""beyond repair"" anyhow!!

I turned the phone off, took the sim out, dropped it onto its back from arm's length (I'm 5'3"" and i have wood floors...) IN UNDER A MINUTE FROM PUTTING BACK THE SIM CARD MY PHONE CONNECTED TO THE MOBILE NETWORK!!!

How full of BS are you Apple flagship store""specialists""???

Blessings to everyone writing in here so i will have the balls to do something like this hahahhaha!!! Thank you, thank you, thank you!!!"

"OMG! The drop method worked perfectly!

1. Have an iPhone 6 that has been dropped with and without a case approximately 1.5 years ago.

2. With clumsy handling and active toddler hands, my Screen was cracked twice

3. Signal (cellular) went out first weekend in November 2016

4. Sprint Tech support tried to trouble shoot- no resolve

5. Best Buy Tech- no resolve

7. Sprint Store- no resolve

6. Apple Store- screen repair with fixed signal issue only to lose signal a few days later

7. Sprint Repair store- Store not allowed to open / repair phone

8. Ifixit- Power phone off, case on phone, go into garage, hold phone 12""-18"" off ground, close eyes and Let Go..power phone on and RESOLVE!!!!!"

Crazy comments on this post! The fact of the matter is a bad connection on the baseband modem following a bend or drop. Due to the screw location. If you have modem firmware and imei then the modem needs reballing. If no firmware then it is eeprom memory or baseband pmu. Don't ever drop the device you will cause more damage. This is plain stupidity!
