I just ordered a quad sim quad band phone over ebay from Hong Kong. Couldn't resist the novelty of having all 4 of my sim cards (Jolt/AT&T, Tuyo/T-Mobile USA, E-Kit Simple Calling (Immix USA/Manx Telecom UK?), and Digicel Bermuda) working at the same time.
Yeah, I know it will run only 2G not 3G sim cards, it is GPRS (not EDGE, 3G or LTE), and it has analog rather than digital TV, but it should still be a lot of fun having a phone with 4 signal strength meters on the screen and a qwerty keyboard for SMS. Currently use an MFU V200 dual sim phone, but now I won't have to change sim chips when crossing borders.
