Hi all:
I am hoping that there are some hardware folks out there that may be able to shed some light on my situation.
I have a 4G Xoom. I wanted to be able to use the same SIM card in my Xoom as my Razr Maxx, but the Maxx uses a micro SIM, so I activated a regular mini SIM in my wife's Spectrum with my phone number and tried the SIM in the Xoom and it worked great. I then cut the SIM down to micro size and put it in my Razr Maxx, again worked great.
I planned on using the remainder of the mini SIM card that I punched the micro SIM from as an adapter for use in the Xoom. I figured that it was a good idea to store the "adapter" in the SIM card tray/slot of the Xoom until I needed it...BAD IDEA! Due to the nature of the spring loaded contacts the "adapter" got stuck, hung up on the contacts. I thought that an easy fix would be to slide something thin in the slot to free up the adapter. It worked in so far as I got the tray and the homemade adapter out, but I must have pressed too hard on the back three contacts as they no longer made contact with a SIM card.
I took the Xoom apart and used a paper clip to raise the contacts back up, but I raised them too far so I went in again and still didn't get it right because although I had a signal on the meter I could not connect to anything. The third time was the charm. I got a signal and was surfing the web!
Now the strange/good part. I now get a full 4G signal (presumably because I am roaming on a non-Verizon tower) as opposed to the usually poor signal at my house. I live right on the edge of a Verizon 4G service area. The Xoom surfs much faster now than before I broke it, but why? Did I short something out? Did I fail to raise one of the contact pins enough? It isn't the SIM, I verified that with another device. I did something to the SIM card slot, contacts, or a related electrical component, but what?
I want to "break"my Razr Maxx and my wife's Spectrum also!
Thanks for any thoughts from any of you hardware guys or anyone that knows how SIM cards work. I don't even know what contact/pin does what.
Thanks

i look into but i see noting, how do you raise it up ?
(i make a mistake, push adapter without micro sim )

You should be able to take it to a local electronic repair man and have them do it, if your xoom is out of warranty.
Hi I have a LG optimus one (p509)
I was puttin in my micro sim adapter and it didn't fit properly. so I jammed it in,
Phone worked fine.
Then when I tried to take it out, three 3 of the four pins got caught in it, the sim wouldn't come out.
So I pulled really hard and now three of the four pins are sticking up.
So no sim cards (not even a regular full size sim card) would go through, so I thought maybe I could force the sim card down and it would work.
So I did that, now when I tried to remove it, it got caught again, so i took a screw driver and took off the thing that keeps the sim card in the slot.
(the metal piece )
Now half of the sim card slot is attached to the motherboard, and the other half is out.
So what do i do?
Can I just soder it back on and it will work?

My phone still boots up and is useable (just no service of course).
better have a technician repair it. i used to have a samsung (old model) the simcard is too loose so i soldered the sim pins (at phone) at yes!!! it failed.
Hello,
Firstly I'm looking for a comment from an expert who has taken Nexus5s apart before. Also I'm beyond the point of returning the phone as this fault developed after replacing a screen and ribbon cable (after I smashed my phone badly). Any help or advice would be great.
So since screen and USB flex replacement on my D821 i notice that my phone signal will connect with full bars, then drop completely, I can also only get 2g where i was able to get higher. The same sim works fine in my nokia. The Wifi Signal is fine and gps works ok but the 'no service' thing makes my phone unusable. I have tried making sure all contacts are clean and even replaced the loudspeaker unit and the black antenna cable but to no avail.
Can someone put up a picture of exactly the components that are involved in the phone signal / 3g setup? Is it possible something could have been damaged on the mainboard to cause this? I can search for networks, connect (sometimes) then it will just cut out.
I tried google for days but cant find a schematic. Basically im trying to determine if there are any other parts i should try exchanging before giving up. It makes no difference how i hold (or dont hold) the phone.
Thanks
I just got this phone today unlocked from tmobile and inserted my custom-cut nano sim into the nano to micro adapter and inserted it into the phone. Everything was fine for a while but i started noticing my data and signal was cutting in and out by itself when the screen was off maybe for 3 minutes or longer. This is a significant problem as you can imagine. I checked every single setting i could and nothing would make it do so. Any advice or suggestions? Im using a straight talk att micro sim card that i had cut down to fit my i5S but came back to android and used a noosy sim adapter. Maybe its the fact that the card is custom cut (so it already doesnt fit the adapter like its supposed to)? I really need help here. Yes i have the proper apn settings and im fully stock.
Bump
I have a nexus 5 "hammerhead" running the latest version of android marshmallow 6.0.1 .
My issue is, the device wont detect any network signal. At first i thought it was a software issue so I downgraded to lollipop and kitkat but the same issue still exist.
All I see is the network provider name, and beside it 'No Service'. I really dont know what else to do, unless this is a hardware issue. Anyone here had experienced the same issue and have it solved? Or am I just going to have to turn this device into a tablet. -___-
p.s. The screen broke and was replaced, and after return of the phone this happened. Is it that the phone repair guy damaged my device?
Plz help!?
Is the imei okay? Are both of the antenna wires properly connected?

yes i can clearly see the imei #. ..and about the antenna wires, yes both are connected but just that the white wire seems abit off. but i tested the continuity and it seemed to work.
The imei is the same before and after the repair?
Did you remove the motherboard and examine it for signs of damage or alteration?

Yes I did. Motherboard checked out ok. Just can't understand why no signal tho. Wifi and Bluetooth works well. And to answer your question, yes imei # is the same.
Also, I was told that the phone fell before the screen replacement and that's when the issue started.
Even if the antenna wasn't connected, it should be able to pickup some amount of signal. If that's not the case then I'll just have to replace the cables and the lower PCB also the speaker area.
Maybe the drop caused a loose connection on the motherboard?
Did you try pressing against the antenna connection points on the motherboard with the back removed?
Well not entirely.. All I tried was checking the antenna wires (which I realized are just the WiFi antennas) and also, tried placing a copper wire in one of the testpoint area that's dedicated to GPRS.
Is it possible that the transceiver may be damaged? Or that's not possible from a simple fall.
Imei is not blacklisted?
Nahh I doubt it. Phone was purchased unlocked was working for a while.. Fell, signal went ..broken screen.. Then once the screen was replaced, inserted sim and it detected sim and also the network but won't gain any bars (service) nor will it detect any other providers.
I would check the imei just in case.
What would I compare that to, apart from what the phone telling me?
I'm registered on the cell network, but no service despite the adjustments of changing the network type or by dialing *#*#4636#*#* and making alterations there.
You can check the imei in swappa.
same problem
same problem with me sim detecting i can see card name but no service in signal bar wifi bluetooh all ok
Pretty wierd

Yeah pretty weird if you ask me. But if you do get a solution to that issue please share :good:
According to Rameeze87, possible hardware issue. Here's the link http://forum.xda-developers.com/google-nexus-5/help/nexus-5-network-signal-wifi-ok-t3310047
Had no idea couldnt duplicate threads, then again it did help to justify the issue.
same
Mine is doing the same thing. Once in a blue moon it will show full bars upon first inserting the sim for maybe three seconds and show provider then drop all the bars and say no service. Dont think there is a simple fix.
Having this issue right now with my wife's phone. Power button broke and was going through endless power cycling so I removed the power button. Got the phone working but will not connect to network. I have checked everything 20 times.
Any solutions?

Yup.. same issue. Phone fell and no mobile signals since (sim gets detected). Everything else is working fine, checked the antenna wires and they are connected properly... Anyone here who was able to get the signals back?
similar issue here in the uk.
N5 phone worked fine for 2 years with a 3 sim.
i changed the knackered battery and that all works and charges ok.
but the 3 sim now wont work(but it does in my motorola moto g), the only sim that will work in my N5 is an O2 sim ???
why does one sim work but not another, the phone isn't locked to a carrier?....
