Mini PCI-E PCI-Express to USB Adapter With SIM Slot Card for WWAN/LTE Module $14.11 + $2.39 shipping

if you need a DC-DC lipo to 5V converter with a bit more (peak) power this one is good.

Here is a suitable outside antenna with a SMA connector.
It supports 433/868Mhz and GSM 900/1800/1900MHz/UMTS and has gain of +3dB
