How to use the SIM card with a phone tablet
Most of the LansTB tablets support SIM cards to make phone calls etc functions. You can find the SIM card slot covers on the back for a few tablets, and most of the tablets have the SIM card slots on the sides. You will need a card removal pin to insert and push to be able to pull out those SIM card slots on the tablets' side.

So far, there are 3 kinds of size SIM cards (standard, micro, nano) available. One tablet usually only supports one size SIM card. Most of the LansTB tablets can be inserted into up to 2 SIM cards.

Please note that not any SIM card would be compatible with the tablet PC you have. Because there are different mobile networks available, such as 2G GSM, 3G WCDMA, 4G LTE, and 5G. What's more, the network bands would vary for different SIM card providers or countries. For example, a 4G SIM card would not work for a tablet that only supports 3G.
