North American ThinkPads have the Sierra Wireless MC8765 card. European ThinkPads have the Sierra Wireless MC8755 card.

The only difference between the two is the frequency at which they support WCDMA. The MC8765 supports WCDMA800 and WCDMA1900, while the MC8755 supports only WCDMA2100.

Both models support GPRS and EDGE at 850, 900, 1800, and 1900MHz.

Both models are category 11/12 UMTS devices, meaning they support up to 1.8Mbps downstream using QPSK modulation. They do not support 16QAM modulation.
