[AC Question]

why does my android phone saying "invalid card "

I tried to replace the SD card with something with more memory but the card was too big so i put the old one back in its place exactly how it was and i kept getting that message and now i cant text or call.

Re: why does my android phone saying "invalid card "

Welcome to Android Central! Which phone? Are you sure you took out the SD card, or the SIM card? The SIM card is needed for your phone to connect to the carrier's network and access the web.

If you mistakenly took out the SIM card, try powering down, remove the SIM again, then make sure it's reinserted correctly again. Refer to the user manual to make sure you're doing it right. Then power back on and see if it works.

Also, which carrier do you use? Some of them will replace the card if it's defective, without a word. Others will say plenty and charge you for a new card.

I just bought a LG Premier LTE Straight Talk phone yesterday. This morning I woke up and it said invalid SIM card. It will not let me turn on my data. It will not let me call or text anyone. It was working fine yesterday. I have tried restoring the phone, I have checked all of the settings, and I have tried taking out the SIM card and then made sure I put it back in properly. I don't know what to do. Any help would be much appreciated.

Try contacting them on Facebook. (That's one problem with them - with a large carrier, you can walk in and have a SIM card replaced.)

I have the same exact problem. I have the lg stylo 2. Bought about 2 nonths ago. Last week out of nowhere i lost signal tgen the invalid sim card msg shortly after. I taljed to straight talk and they sebt me a new sim this past Sunday. Put it in and my phone worked fine. Well 2 days later (today) same exact thing happened. Brand new sim card and phone is only a couple months old. I cannot make or recieve calls or txts. No data nothing. Its getting rediculous and i have yet to find a way to fix it or figure out whats cuasing it. I havent changed any of my settings at all. Abd i have removed cleaned and double checked my sim card as well as rebooted my phone multiple times. Any answer to why this is happening would be great

Hi, I've got an LGG4, for the last 4 days my mobile switches itself off, when it comes back on it says invalid sim card, I've searched for a reason but I'm assuming that it's because of an update recently installed, another forum site is inundated with the same problems, all LG mobiles, apparently we can't unistall updates so they are stumped as to how to resolve the issue , hope this helps x
