Samsung Galaxy Tab 3 SM-T215 Sim card slot - Galaxy Tab 3 Q&A, Help & Troubleshooting

Hi everyone.
I have a Singapore version of samsung Galaxy tab 3 SM-T215 LTE version. Problem is that pins in the sim card slot got damaged and I tried to do a replacement, however in the process I accidentally damage one on the "Solder pad" on the circuit meant for the sim slot (shown in the picture).
I would really appreciate if anyone could tell me which part of the circuit board does it connected to, so I can use a wire to do a bypass.

That's mean no network detected.
Try changing to another carrier. Maybe your current network provider is down.

[Q] ANyone know how a SIM card connects to the SIM reader?

Hi All,
As you can see from the picture I have broken the three brass bits off one end of my SIM card reader
Although I have lost the missing bit, I am going to try and replace them.
Does the connection JUST have to be made at A or when the SIM is inserted, do those pins have to connect to the very small contacts marked B
Any help appreciated

External GSM/CDMA/LTE/4G external antenna for android smartphones

I wonder if is it possible to connect an external antenna for data (not wifi) to any android smartphone, so you don't have the antennas physically near you and radiating you with microwaves. 3 feet or more would be desirable.
Something like this, but with the android smartphone/tablet instead of the computer:

H815 Mainboard (RF) connectors

Hello everyone,
I've got a bricked LG G4 H815 mainboard lying around. Recently, i've noticed that there are 5 empty connectors scattered across it

In the service manual they are referred to as RF connectors (Part number: EAG63772101, location number: SW1002,SW1005,SW1101,SW1102,SW1106).
Since they say "RF", it seems likely that they are Antenna connectors (?). Does anyone have an idea, what they are used for?
Thanks

Verizon Galaxy Note8

Hello everyone!
I have a Verizon Galaxy Note8. When I try to insert other sim card, is saying sim card is not from Verizon wireless. Tried to change the ROM and firmware but no luck. Searching the internet I have read that I can root the phone, so my next step in this experiment is to root the phone, but I have no experience in doing this!
Model number: SM-N950U
Thank you!
One of these numbers wth *#*#number#*#* will give you a menu and you can change CSC from there or at least I can
