Can I use Huawei E8231 datacard without a pc or usb port?
Yes, You can use. Huawei E8231 is a hardware based WiFi hotspot. So it does not require a pc or any software to work. A pc usb port is not necessary but it is powered by usb port, so you atleast need a usb power source to use it. You may plug it directly to a usb wall power outlet, power bank with usb charging outlet or your car usb charger port and it will work.

What type of sim card is required, micro sim or normal sim?
It needs a normal sim card, which means a mini sim card. You may also use Micro or Nano sim cards with adapters but I do not recommend using adapters as they get stuck sometimes and damage the pins on the dongle/phone.

Does it work with CDMA.
No. The datacard works only on GSM

What frequencies are supported in GSM/WCDMA?
EDGE/GPRS/GSM 1900MHz/1800MHz/900MHz/850MHz

What is the difference between other data cards and huawei E8231
The main difference is in the WiFi and Hotspot functionality.

Many datacards are usb only, meaning you will have to attach the datacard to your pc/mac usb port to be able to use the data connection. You can not use these data cards with your mobile phones/tablets.

Some datacards have SoftWiFi functionality, which means you can create a WiFi Hotspot using an application on your PC. The hotspot can be shared with other computers/phones/tablets. So your phones/tablets can access the WiFi hotspot of your datacard just like as they can access any other WiFi. But the limitation is that the data card still needs to be attached to your pc and pc and the required applicaton needs to be running as long as you want WiFi zone.

Huawei E8231 (and some other models from Huawei and other companies) can create a WiFi Hotspot without need of a pc. This WiFi hotspot is hardware based. Just connecting the E8231 to any usb power will create a hotspot. So all your WiFi devices can access the hotspot.

All you need to do is connect the E8231 to a usb wall adapter(charger), car usb adapter(you have a mobile wifi zone now), power bank usb port(or even a pc usb port). Once it is powered, the WiFi zone will be created.

You can also use the E8231 normally without WiFi by attaching the datacard to the usb port on your pc/mac.
