So the SIM had a tiny bit of water damage but the guy at the store said the SIM isn't really a problem like that and he was right it was perfectly working until like a while ago where it used to like lose the connection to it so I just took it out and put it back again and now it's come back and my fix worked but now it's not working anymore and my SIM isn't loading
Is this a good question?

Hi @rotemmesika
Did the guy at the store open the phone to check if there was any water damage or not to the internal components?
The phone is not waterproof. It only has an IP53 splash resistant rating.
The phone needs to be opened and the internal components checked if there is any evidence of corrosion and water damage.
The impurities in the water causes corrosion and provides circuit paths for the electricity which were not in the phone's operating design and could damage the components. The corrosion starts immediately and is ongoing until it is completely cleaned away
Do not try to charge or to turn on your phone anymore and then remove the battery as soon as possible from the phone to minimize any further damage.
Then you need to dis-assemble the rest of the phone and clean all the affected parts using Isopropyl Alcohol 99%+ (available at electronics parts stores) to remove all traces of corrosion and water. If possible do not use "rubbing alcohol" as in some cases this is only 70% IPA or less, can contain additives which may leave conductive residues and is not as effective. If you do have to use it check the label to verify the amount of IPA. The higher the percentage of IPA the better
Here is a link that describes what happens. Electronics Water Damage
As always with electronics, especially surface mounted pcb be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the board. Remove the shields that may be covering some components as the water may have got in under there. The ends of any flex cables and their connectors need to be cleaned as well
Hopefully after you have done all this the phone might possibly work correctly again.
Here is a teardown video that may help.
If this process seems too daunting, take your phone to a reputable, professional phone repair service, experienced in liquid damage repair and ask for a quote for a repair. If you decide to do this, do it sooner than later.
