Will it work while charging and what is the best SIM Card/Carrier to use?

YES I first contacted LAYEN to confirm it worked while charging. After purchasing tested it with a myriad of power banks/external battery packs as well as plugged right into the wall and they all worked. Dang good thing because without another power source, the battery life in this thing is only 2 hours of continuous use. Truphone SIM card is best in my opinion. I'm in the USA.

In my experience, it charges great, but the connection to play music/use the phone through the cable doesn't work well. Bluetooth connection is best in that case.

Yes this will charge. Turn your phone completely off or your ipad. It'll charge, But not as fast as with the wall charger. The only reason it says not supported is cause you're trying to charge while it's active, so it's trying to use the active power input while it charges the battery. So it needs more input power while it's on, then while it's off.

No. But it is best practice to only charge a phone when it has lees than 20% battery. Yes you can use the device and charge at the same time.

Hello! Yes, the booster works while charging. I have used it this way many times. If it runs completely dead, it will take a few minutes of charging before it will power up for use. Good Luck.

Same as C F, after a while of using it while plugged in, the USB port has become a bit lose and it will mess up as you move around with the cable plugged in. So yeah, it will work while charging, but you will losen up your USB port and eventually, you won't be able to use it while charging.

Yes, it still works while charging. I tried this out with a travel charger in my car. I had my iPhone connected to it playing music through my car stereo; all while the device was being charged.

yes it can work and charge at same time. charging it requires powered usb port. you can get a usb port for charging that connects to wall outlet if you don't have a nearby powered usb port.

Yes, you can use the phone or other device while charging. Full charge takes about 45 min to an hour if pretty empty. With a longer charge cord I leave the battery in my pocket while using the phone.

I have used mine while in the charger so would say yes it works. It was already in the charger when the phone rang so don't know if putting it in the charger while on the phone will disconnect it

Yes you can use it while charging, this is my third one, can't remember the others names but they were pos. This one is the best by far.

Yes you can use it while it is charging .When I get the low battery tone, I plug it in, power it up and it reconnects with my phone while it charges.The light turns red while charging and green when fully charged.

It is rechargeable and depending on device you will be to charge 2 devices before having to recharge the battery. As far as using the phone while charging you should be able to, should be no different than having it plugged into a regular charger.

It will charge as long as your phone asks for a charge.. That said, your phone should be smart enough to stop asking for a charge once it's full.. I believe they all do..

Yes you can use it while charging, but it can only be charged via USB cord.

Yes, the phone can be charged/powered while docked. You need a car charger, which can remain attached to the dock.
