If you've decided the voice and data plan your current network provider supplies your Samsung Galaxy Tab with is too stingy, it may be time to jump ship to another carrier. Connecting your device to a new carrier will involve freeing it from your old network provider and replacing its SIM card. This may sound like a simple process, but you could damage your device or be left without 3G/4G services if you go about it in the wrong way.

Content your network provider and ask for an unlock code. If your carrier has locked your tablet, SIM cards from other companies won't work in it. Some carriers may charge you for an unlock code, while others will provide one for free. It will be unlikely your slate is locked if you bought it SIM-free without a contact.
Hold down the "Power" button at the side of your Galaxy Tab and select "Power off" from the "Tablet options" menu that displays on your screen. Tap "OK" after you're informed that your device will shut down.
Open the SIM card slot cover on the other side of your tablet. Push the top of the SIM card that's currently in your device to release it. You'll then be able to slide it out of the SIM slot.
Slide your new SIM into the card slot until it locks in place. Replace the card slot cover, power your device back on and test data and voice services.
Tips and warnings
- You may need to activate your new SIM before you can access services through it. Contact your carrier if you're having problems accessing voice or data services.
- If you're out of contract with your current network provider and are using its services on a rolling monthly basis, you'll typically need to supply 30 days notice to cancel your service.
- Check what type of SIM card your Galaxy Tab uses before ordering a new one. A traditional SIM won't be much use to you if your slate takes a micro SIM. Older versions of the device take a traditional SIM, while newer ones use micro SIMs.
- Don't insert or remove a SIM card while your device is powered on. Doing so may harm the SIM card and your tablet.
