When Orange Pi 3G-IoT SBC was launched, I looked at 3G USB dongles to make a comparison with a similar setup based on a Raspberry Pi Zero W board and an inexpensive 3G USB stick, and the cheapest I could find was a refurbished HUAWEI E3533 model now selling for around $16 shipped.
But I’ve just found one fairly cheaper with LEORY 3G USB dongle offered for only $9.99 including shipping on Banggood.

The dongle is said to be supported in Windows 2000/XP/Vista/7/8/10, as well as Linux and Android operating systems, and no extra drivers are required, they’ll just be installed automatically by the OS.
The 3G USB dongle supports data & SMS functions, and can be used with laptops, computers, tablets, development boards, etc… The micro SD card slot inside the device means it can also be used as a USB thumb drive up to 16GB.
Based on the specs, only 2100 MHz (Band 1) networks are supported, which means 3G UMTS should be supported in most countries, but not in the US or Canada, nor Latin America.
