It's a WWAN 3G adapter, so you can connect to a 3G network. You will also have to insert a SIM card to be able to use it. If you never use it you can remove it and replace it with a SSD. Make sure to isolate the antenna connectors with something like scotch.

im pretty sure this cards drivers dont work well with win10 anyways, soo...

pretty sure most 3G networks that worked with are shut down now anyway

yea, likely why they didnt bother

First off 3G is dead. If your battery is removed it won’t matter which wire you remove first. Important to note .. battery removed and unplugged.

those are just antenna wires, they lead to passive antennas. Can be unplugged anyways, id still remove the battery tho bc who knows what the metal plugs will hit on the board when disconnected

battery out and no power prevents an accidental spark.

as said, not caused by the antennas but by their plugs touching the board. Theres no power on these wires.

Thanks friends. I mounted msata ssd, win10 after cloning it and it works perfectly. In the end, nothing exploded 😄

That is always a good thing

I’m pretty sure it’s a cellular antenna just like your Wi-Fi but it’s a lot bigger and in the M sata port

Thank you!! how do i detach the red and blue wires?

start with the blue. oh wait no, the red! or should we be waiting for the bomb defusal unit?

you just detach

if you use your screw driver to lift up the wire it will tilt the right way and seperate from the connector very safely. If done wrong you do risk ripping the SMD port off the board. It has happened to me before.

This is a 3g wwan modem. There are still a lot of countries where 3g is working perfectly fine, so it is still possible to use them. Drivers should also work just fine.

If you decide to remove the modem and use an msata ssd instead, make sure to isolate the antenna wires (for example with electrical tape or heatshrink) so they do not short circuit the board.

That's a 3G card, you can remove it if you don't use a sim card

It's a 3G / WWAN card. You can remove it
